Predicting hunter behavior of indigenous communities in the Ecuadorian Amazon: insights from a household production model
Provedor de dados: 7
Autores: Maldonado, Jorge H; CEDE - Department of Economics, Universidad de los Andes; jmaldona@uniandes.edu.co.
Many indigenous communities living in the Amazon rely on hunting and fishing to meet the majority of their protein needs. Despite the importance of these practices, few studies from the region have analyzed the socioeconomic drivers of hunting and fishing at the household level. We propose a household production model to assess the effect of key economic parameters on hunting and fishing in small indigenous communities located in the Ecuadorian Amazon, whose principal source of protein is derived from hunting and fishing. The model was validated using empirical data from two communities that reflect different levels of market integration and forest conservation. Demand and supply functions were generated from household data gathered over 19 months....

We review the evidence for multiple ecological states and the factors that create ecological resilience in coral reef ecosystems. There are natural differences among benthic communities along gradients of water temperature, light, nutrients, and organic matter associated with upwelling-downwelling and onshore-offshore systems. Along gradients from oligotrophy to eutrophy, plant-animal symbioses tend to decrease, and the abundance of algae and heterotrophic suspension feeders and the ratio of organic to inorganic carbon production tend to increase. Human influences such as fishing, increased organic matter and nutrients, sediments, warm water, and transportation of xenobiotics and diseases are common causes of a large number of recently reported ecological...

Autores: Marshall, Nadine A; CSIRO; nadine.marshall@csiro.au; Marshall, Paul A; Great Barrier Reef Marine Park Authority; p.marshall@gbrmpa.gov.au.
How can we tell whether resource-dependent people are socially resilient to institutional change? This question is becoming increasingly important as demand for natural resources escalates, requiring resource managers to implement policies that are increasingly restrictive on resource users. Yet policy changes are frequently made without a good understanding of the likely social and economic consequences. Knowledge of the resilience of resource users to changes in resource-use policies can assist in the design and implementation of policies that minimize the impacts on people while maximizing the sustainability of ecosystem goods and services. Despite the appeal of resilience as a framework for sustaining human-environment relations, there has been a...

Reproductive biology of the swimming crab Achelous spinimanus (Decapoda, Portunoidea): a potential fishing resource
Provedor de dados: 76
Autores: Sousa,Aline N.; Bernardes,Veronica P.; Bernardo,Camila H.; Taddei,Fabiano G.; Teixeira,Gustavo M.; Costa,Rogério C.; Fransozo,Adilson.
ABSTRACT This study describes the reproductive and recruitment patterns of the swimming crab Achelous spinimanus (Latreille, 1819) in the Ubatuba region of the northern coast of São Paulo, Brazil. Crabs were captured monthly from January 1998 to December 1999 in 18 sites located in three bays (Ubatumirim, Ubatuba, and Mar Virado), using a commercial fishing boat. In each sampling area, bottom temperature, salinity, and organic matter content were recorded. A total of 1,911 individuals were captured: 350 adult males, 475 non-ovigerous adult females, 584 adult ovigerous females, and 502 immature individuals. Reproductive females were more abundant in deeper areas; this migration might be a strategy to improve larval dispersion and survival. Ovigerous females...

Compactation for a better management of marine biomass: applications to fish discards and by-products
Provedor de dados: 5
Autores: Perez-galvez, Raul.
In the framework of the future application of a zero-discard policy in EU fisheries, this thesis aims to develop and implement an efficient and integral waste management both on board the fishing vessels and in land (fish auctions and fish processing industry). To this end, it proposes a compaction operation able to reduce the volume and the water activity of the fish wastes, thus favouring their handling and reducing the economical costs associated to their transport and storage. To asses the viability of a waste compaction operation, the main operation factors governing the process were identified, and their influence upon the performance of the compacting operation was investigated by a statistical approach. Sardine was chosen as fish species since it...

Autores: Moullec, Fabien; Barrier, Nicolas; Drira, Sabrine; Guilhaumon, François; Marsaleix, Patrick; Somot, Samuel; Ulses, Caroline; Velez, Laure; Shin, Yunne-jai.
The Mediterranean Sea is now recognized as a hotspot of global change, ranking among the fastest warming ocean regions. In order to project future plausible scenarios of marine biodiversity at the scale of the whole Mediterranean basin, the current challenge is to develop an explicit representation of the multispecies spatial dynamics under the combined influence of fishing pressure and climate change. Notwithstanding the advanced state-of-the-art modeling of food webs in the region, no previous studies have projected the consequences of climate change on marine ecosystems in an integrated way, considering changes in ocean dynamics, in phyto- and zoo-plankton productions, shifts in Mediterranean species distributions and their trophic interactions at the...

Towards multidisciplinary indicator dashboards for coral reef fisheries management
Provedor de dados: 5
Autores: Clua, Eric; Beliaeff, Benoit; Chauvet, Claude; David, Gilbert; Ferraris, Jocelyne; Kronen, Mekhi; Kulbicki, Michel; Labrosse, Pierre; Letourneur, Yves; Pelletier, Dominique; Thebaud, Olivier; Leopold, Marc.
The diversity of reef ecosystems, the multiplicity of reef resource uses and the breadth of the range of the island socio-cultural contexts concerned make coral reef fisheries (CRF) management in the South Pacific a complex task. The health and state of the targeted resources depend both on ecosystem characteristics (as determined by ecological and biological factors) and on fishing pressure, whose effects are only partly known. Increasing harvests from commercial and recreational fishing increasingly overlap with traditional Subsistence activity, creating an important CRF management challenge. This paper presents a new approach to CRF assessment and monitoring by providing a set of multidisciplinary indicators. The fisheries system is assessed from three...

Oyster reefs are among the most threatened marine habitats globally. In Europe, oyster reefs have been extirpated from most locations within their historical range. Active restoration of the native oyster (Ostrea edulis) in Europe has grown substantially in recent years. In sharing experiences between oyster restoration projects in Europe at the Native Oyster Restoration Alliance conference, NORA2, in Edinburgh in May 2019, it became apparent that a number of similar barriers are experienced. This study identified the top 40 questions, which, if answered, would have the greatest influence on the policy and practice of oyster restoration in Europe. Initially 71 people were consulted across 28 institutions and 11 European countries to generate 194 questions....

Sensitivity of marine systems to climate and fishing: Concepts, issues and management responses
Provedor de dados: 5
Autores: Perry, R. Ian; Cury, Philippe; Brander, Keith; Jennings, Simon; Moellmann, Christian; Planque, Benjamin.
Modern fisheries research and management must understand and take account of the interactions between climate and fishing, rather than try to disentangle their effects and address each separately. These interactions are significant drivers of change in exploited marine systems and have ramifications for ecosystems and those who depend on the services they provide. We discuss how fishing and climate forcing interact on individual fish, marine populations, marine communities, and ecosystems to bring these levels into states that are more sensitive to (i.e. more strongly related with) climate forcing. Fishing is unlikely to alter the sensitivities of individual finfish and invertebrates to climate forcing. It will remove individuals with specific...

The research programme developed within in the framework of the project study of the Paluel site allowed us to highlight, near the drainage channel of the Durdent, a sea trout fishery using fixed nets in the area of the swaying of the tides. This activity, very much in use in the eastern English Channel and along the southern shoreline of the North Sea, not only for catching certain amphibiotic species but also species that are strictly of the sea, represents a sizeable cause of the mortality rate for salmonid populations during their coastal migrations. The studies begun on this fishery in 1980 have as their goal to assess the size of the salmonid catches near the site, especially of sea trout, and to acquire more complete knowledge of the catch, biology...

Trawling activities are considered to be one of the main sources of disturbance to the seabed worldwide. We aimed to disentangle the dominance of environmental variations and trawling intensity in order to explain the distribution of diversity patterns over 152 sampling sites in the French trawl fishing-ground, the Grande Vasière. Using a towed underwater video device, we identified 39 taxa to the finest taxonomic level possible, which were clustered according to their vulnerability to trawling disturbance based on functional traits. Using generalized linear models, we investigated whether the density distribution of each vulnerability group was sensitive to trawling intensity and habitat characteristics. Our analyses revealed a structuring effect of depth...

Analyse quantitative et qualitative des captures de tourteaux Cancer pagurus par la flottille de Manche-ouest
Provedor de dados: 5
Autores: Latrouite, Daniel; Morizur, Yvon.
French potters from « Manche ouest » harbours ish edible crab Cancer pagurus in English Channel, Iroise Sea and along north Biscay Bay shelf. Monthly landings of the offshore fleet analysed from logbooks for the period 1985-1987 indicate changes in fishing areas. The mean length of males, the mean length of females and the sex-ratio have been analysed by Principal Component Analysis in 1981-1987 samples. The heterogeneity between catches from different statistical rectangle (30 x 40 nautical miles) was great enough to deduce a way of raising composition from samples to total landings. It also offers the possibility to verifiy and correct declaration on geographical origin of landings.

Optimisation of trawl energy efficiency under fishing effort constraint
Provedor de dados: 5
Autores: Priour, Daniel; Khaled, Ramez.
Trawls energy efficiency is greatly affected by the drag, as well as by the swept area. The drag results in an increase of the energy consumption and the sweeping influences the catch. Methods of optimisation of the trawl design have been developed in order to reduce the volume of carburant per kg of caught fish and consequently the drag per swept area of the trawl. Based on a finite element method model for flexible netting structures, the tool modifies step by step a reference design. For each step the best-modified design, in terms of drag per swept area is kept. Such optimisation can lead to a decrease of the drag or an increase of the swept area. In the second case, that could lead to an increase of fishing effort. To avoid such increase, which could...

This study concerns mainly 2 species Merluccius capensis and M. paradoxus; M. polli is a more northern species though the 3 species are known to inhabit the same regions. The life cycle, seasonal migrations geographical distribution and fishing grounds of the 2 main species are discussed in detail. The intensity of fishing in this region, over the past 10 years has increased to such an extent that during 1968 -1970 this production accounted for one half level on a world-wide basis. Attempts have been made by Britain to market this fish as a frozen product.

Exploring the abundance-occupancy relationships for the Georges Bank finfish and shellfish community from 1963 to 2006
Provedor de dados: 5
Autores: Frisk, Michael G.; Duplisea, Daniel E.; Trenkel, Verena.
Abundance-occupancy (A-O) patterns were explored temporally and spatially for the Georges Bank finfish and shellfish community to evaluate long-term trends in the assemblage structure and to identify anthropogenic and environmental drivers impacting the ecosystem. Analyses were conducted for 32 species representing the assemblage from 1963 to 2006 using data from the National Marine Fisheries Service's annual autumn bottom trawl survey. For individual species, occupancy was considered the proportion of stations with at least one individual present, and abundance was estimated as the mean annual number of fish captured per station. Intraspecific relationships were estimated to provide information on utilization of space by a species. Multispecies...

Connectivity is a crucial process underpinning the persistence, recovery, and productivity of marine ecosystems. The Convention on Biological Diversity, through the Aichi Target 11, has set the ambitious objective of implementing a ‘well connected system of protected areas’ by 2020. This paper identifies eight challenges toward the integration of connectivity into MPA network management and planning. A summary table lists the main recommendations in terms of method, tool, advice, or action to address each of these challenges. Authors belong to a science–management continuum including researchers, international NGO officers, and national MPA agency members. Three knowledge challenges are addressed: selecting and integrating connectivity measurement metrics;...

There is an increasing need to understand community-level or whole-ecosystem responses to multiple stressors since the impacts of multiple stressors on marine systems depend not only on species- level responses, but also on species interactions and ecosystem structure. In this study, we used a multi-model ecosystem simulation approach to explore the combined effects of fishing and primary productivity on different components of the food-web across a suite of ecosystems and a range of model types. Simulations were carried out under different levels of primary productivity and various fishing scenarios (targeting different trophic levels). Previous work exploring the effects of multiple stressors often assumed that the combined effects of stressors are...

La gestion des ressources et des territoires : Application à la mise en oeuvre de projets de valorisation de sous-produits de poisson
Provedor de dados: 5
Autores: Penven, Anais.
Beyond the technical and technological advances in the conversion of marine by-products into useful products, the territorial, economic, social, political and environmental parameters, which govern all forms of approaches for fish by-products upgrading, must be taken in account. This is essential to understand why and how bioconversion technologies are applicable. The fishery sector is facing several issues such as fish stocks weakening, recourse to imports, aquaculture rising or consumers behaviors which complicate the approach of fish by-products upgrading as it is linked to the raw material processing. Thanks to some projects addressed this thematic in recent years, several quantitative and qualitative data about by-products deposits are available....

Biologie et pêche traditionnelle des crevettes pénéides dans l'embouchure d'un fleuve en milieur semi-aride (sud-ouest de Madagascar)
Provedor de dados: 5
Autores: Laroche, Jean; Benoely,; Siaviri, A.
Traditional fishing using beach seines was studied over a period of one year at the mouth of the Onilahy river. The catches/efforts were recorded on a daily basis, biological sampling and the measurement of hydrological parameters being carried out twice a month. The moderate variations of salinity and temperature (14 &lt; salinity &lt; 35; 25 degrees C &lt; temperature &lt; 30 degrees C) which were observed in the estuary can be explained by the semiarid climate of the area. Four species of penaeid shrimps are to be found on the Onilahy: Metapenaeus monoceros, Panaeus indicus, Penaeus monodon and Penaeus japonicus, which were mainly caught at the subadult/adult stage with a Carapace length between 10 and 50 mm.

Using a spatially structured life cycle model to assess the influence of multiple stressors on an exploited coastal-nursery-dependent population
Provedor de dados: 5
Autores: Archambault, B.; Rivot, E.; Savina-rolland, Marie; Le Pape, Olivier.
Exploited coastal-nursery-dependent fish species are subject to various stressors occurring at specific stages of the life cycle: climate-driven variability in hydrography determines the success of the first eggs/larvae stages; coastal nursery habitat suitability controls juvenile growth and survival; and fisheries target mostly adults. A life cycle approach was used to quantify the relative influence of these stressors on the Eastern English Channel (EEC) population of the common sole (Solea solea), a coastal-nursery-dependent flatfish population which sustains important fisheries. The common sole has a complex life cycle: after eggs hatch, larvae spend several weeks drifting in open water. Survivors go on to metamorphose into benthic fish. Juveniles...

Development of a model for flexural rigidity of fishing net with a spring mass approach and its inverse identification by metaheuristic parametric optimization.
Provedor de dados: 5
Autores: Vincent, Benoit; Di Cesare, Noëlie; Simon, Julien.
The assessment of mesh resistance to opening is a key factor when coming to fishing gear design to study or optimize the fishing selectivity process. Different authors proposed methodologies to achieve twine flexural rigidity identification and mesh opening angle at rest. Their experimental protocols could rely on complex installations and instrumentation, and identification needs dedicated models or software with possible important set up time. Sometimes, different flexural rigidity and rest angle values for a given netting type were proposed depending on identification or experimental conditions, leading to difficulties to choose a value for implementation in netting structures simulation software. The new methodology proposed in this article is based on...

The objective of the project is firstly, to assess the fuel consumption for the fishing technique of Danish seine including assessing its distribution in each phase of its implementation and secondly, investigate potential improvements in energy consumption. Sensors on the boat and on the gear have been installed. Measurements were carried out during sea trials. The boat and gear were simulated. From these measurements and simulations, we observe that the route and fishing phase have more or less te same consumption (58% and 42%). During fishing phase, the gear focuses the main share of consumption (60%). This energy is transmitted to 2/3 by winches and 1/3 by the propulsion. Areas for improvement were evaluated: Changing the type of winch (electric vs...

The integration of fishing management into the ecosystemic approach has been recommended for many years by international consultative bodies; it is also written into international conventions and agreements. The implementation of the ecosystemic approach involves the development of programmes for monitoring exploited ecosystems in order to measure the effects of management steps. Plotting the results of these observations for operational reasons requires formalizing summary performance indicators.  IFREMER has carried out halieutic observation campaigns for some twenty years along the coasts of France from oceanographic ships and chartered ships. The objective of these campaigns is to produce abundance indices of species that are of halieutic interest....

Contribution a l'étude de l'étrille Necora puber dans le Mor-Braz : données halieutiques, biologiques et pathologiques
Provedor de dados: 5
Autores: Wilhelm, Gwenaëlle.
The velvet swimming crab Necora puber, commonly found on the French coast was an important resource for inshore fishermen of the Mor-Braz sea in Southern Brittany before the production collapsed in 1985. Although there are still many uncertainties as to the reasons for this, we note that the collapse took place after a significant ecological imbalance which locally caused massive mortality of many marine organisms in 1982.  Without being obviously linked to the former point, mortality due to pathological causes was observed in velvet swimming crabs. Seeing the lack of general knowledge about these crabs, this study was designed to acquire data about its fishery and its biology. The first part focused on fleet, fishing effort and yield trends in the...

Introduction : Intra-basin fishing is not grasped as well, partly because of a lack of distinction between pure professional fishing units and conchological units and on the other hand because of the large amount of ships. Poorly adapted codification of the equipment found in the basin is also contributing to this lack of information. Studies on the subject do exist, but the elements necessary to publish notices are not always gathered, this is leading to the proposal of a geographical systemic analysis on the basin. The steps that are being taken are complementing the development of the Geographical Information System already in place in the basin since 1993 through DEL at the Arcachon Ifremer as well as the PECOSUDE European study ¿ caractéristiques des...

Compte rendu des essais de pêche du Laminaria hyperborea
Provedor de dados: 5
Autores: Arzel, Pierre; Mingant, Christian; Noel, Philippe; Gourronc, Eugene.
Introduction  During the month of April 1994, the "Ressources Halieutiques de l'Ifremer" laboratory (Ifremer Halieutic Resources) in Brest tested tools to be used for the harvesting of Laminaria hyperborea as requested by Système Bio-Industries. The first results of this trial campaign are as follows: The tools are effective as far as interspecific as well as intraspecific selectivity. Rightly so, Laminaria hyperborea accounts for nearly 100% of the harvest. We also noticed that only large size plants are harvested, commercial harvest is satisfactory in terms of yield. However insufficiencies still remain. Comb efficiency is low, since the actual harvest only represents 10 to 12% of the stipes collected when the machine goes through.  This low efficiency...

Pêche de la langouste rouge Palinurus elephas en france. Eléments pour fixer une taille marchande
Provedor de dados: 5
Autores: Latrouite, Daniel; Noel, Philippe.
From the end of XIX century to the 1950', spiny lobster (Palinurus elephas) fishing has been an important economical activity for potters of Brittany and led to landings over two thousands tons. Later, impoverishment of traditional fishing grounds and closure, to French fleet, of foreign fishing area obliged a reconversion of potters toward crabs (edible crab and spider crab). Recently in the 80', development of a netting activity has restarted catches of spiny lobster (at a modest scale). Presently, the only reglementary measure concerning this species/metier is a national minimum legal size (total length) but European Commission has wished that a European MLS would be established. In that aim, this paper presents the main features of spiny lobster...

Towed Gear Optimisation, application to trawls
Provedor de dados: 5
Autores: Roullot, Jean; Vincent, Benoit.
IFREMER has been developing and commercialising scientific software to help the conception and optimisation of any kind of trawl. This software named DynamiT makes available a "virtual flume tank" where tests can be achieved without any constraint due to scale effects or other limitation when physically testing out. DynamiT has been used numbers of times to simulate and optimise trawls by different net makers and by IFREMER. The software is based on the resolution of the mechanics (structure and hydrodynamic) equations of a model describing the actual trawl and its rigging. The "user friendly" interface allows the user to iterate "modification and observations" cycles to reach an optimised state of the fishing gear. The process can be used to reduce the...

Autores: Durand, Jean-louis.
Introduction: Marine organism mortality in the Vilaine bay during July-August 1982, consecutive Dynophysis growth since that date prohibiting shellfish commercialisation, repetitious conflicts among sea professionals are the reflection of a fragile ecosystem and current instability of halieutic resources exploitation in Mor Braz . Becoming aware of this fragility the Ministère de la Mer (Ministry of the Sea) initiated the creation of the Commission Quadripartite (Quadripartite Commission) in charge of the Hydrobiologic Protection and Alieutic Development of the Quiberon-Vilaine bay, bringing together administrative and scientific professionals. Right from the start, among the missions entrusted to the Commission, the will to study the halieutic future of...

Autores: Morizur, Yvon; Antoine, Loic.
The exploitation of the living marine resources should take into account the effects on marine ecosystems. It consequently includes direct and indirect impacts of fishing activities on marine communities of non-market value for the fishing industry. Protecting the marine species victims of by-catch such as sea mammals is essential as it could be a serious threat for endangered species -See COM (1999) 363 final. The entire group of cetaceans are among the protected species listed by CITES against over-exploitation through international trade. Similarly, several international agreements on cetaceans conservation have been signed, including the Agreement on the Conservation of Small Cetaceans of the Baltic and North Seas (ASCOBANS), the ACCOBAMS agreement for...

Changements adaptatifs induits par la pêche chez les populations halieutiques
Provedor de dados: 5
Autores: Marty, Lise.
Fishing is an important source of mortality in harvested populations and therefore may induce adaptive responses. These responses affect life-history traits in particular, which have consequences for stocks’ dynamics, and thus can alter the demographic direct effect of fishing (i.e. the reduction in stock’s biomass). Fishing-induced adaptive changes depend, non-exclusively, on two processes: evolution and phenotypic plasticity. These two components are observed at the phenotypic level because functional genes coding for the traits undergoing adaptive changes have not yet been identified. These two origins are confounded in individual phenotypes, and the impact of adaptive changes in the long run remains therefore unclear: evolutionary changes are expected...

Ce rapport fait la synthèse des travaux réalisés en 2008 et en 2009 au cours du programme Selecmer. Celui-ci, réalisé à l'initiative des professionnels de la pêche en partenariat avec l'Ifremer, avait pour objectif de travailler à améliorer la sélectivité du chalut de fond qu'ils utilisent afin de diminuer les rejets des individus hors-tailles1, en particulier pour le merlan, tout en limitant les pertes commerciales immédiates. Une première phase a consisté à tester l'efficacité de fenêtres à mailles carrées. La deuxième phase a eu pour objectif de développer une grille sélective. Des essais en bassin et des campagnes vidéo en mer ont permis d'apporter des ajustements aux dispositifs sélectifs. L'ensemble des essais de sélectivité à bord des navires de...

Fishing effects and life history traits: a case study comparing tropical versus temperate tunas
Provedor de dados: 5
Autores: Fromentin, Jean-marc; Fonteneau, Alain.
This study aims to test whether exploitation affects tunas and tuna-like species displaying contrasting life history traits similarly. We first collected information on life history of 10 commercial Atlantic species and then compared this information using multivariate analysis. On one hand, tropical tunas are characterised by small to medium size, rapid growth, early age-at-maturity, long spawning duration and short life span. These species, therefore, display a rapid turnover, characteristic of r-selected species. On the other hand, temperate tunas display differing life history traits, i.e., large size, slow growth, late age-at-maturity, short spawning duration and long life span. The turnover of these species is slow and present characteristics similar...

The scientist community, the fishing organisations and all involved parties show a growing interest in an integrated project management of the sea space exploited by fishing communities. A key to reach such a target is to make available reliable and precise scientist data on the different components of the fishing systems.  For about twenty years, and in its mission to support the development of an integrated management for a sustainable use of marine resources, Ifremer has been organising monitoring campaigns of fishery resources along the shores of France. These campaigns aim at providing abundance indicator on species of interest. They consequently provide an essential knowledge base to characterize and trace the status of exploited fish and...

Le gouvernement du Sénégal s’est engagé, en élaborant le Plan directeur des pêches en 1998, à mettre en oeuvre « une politique de gestion prudentielle » de la ressource halieutique, conformément au Code de conduite pour une pêche responsable (FAO,1995). D’où l'intérêt d’examiner les contraintes à la conservation et à l’exploitation durable de la ressource et comment lever ces contraintes. La situation des pêches est caractérisée par un état critique de la ressource halieutique du fait de plusieurs facteurs, la surpêche entrant en première ligne. Plusieurs contraintes ont été identifiées. Les principales sont l’absence d'une démarche de planification dans la gestion des ressources halieutiques, le problème de l'appropriation de la réglementation, la...

Estimación del crecimiento y mortalidad del chivo cabezón Ariopsis bonillai (Miles, 1945) (Pisces: Siluriformes: Ariidae), en la Ciénaga Grande de Santa Marta, Colombia
Provedor de dados: 20
Autores: Galvis-Cortés, O.D.
A partir de septiembre de 1981 y durante 14 meses consecutivos de muestreo en la Ciénaga Grande de Santa Marta, se capturaron 3477 ejemplares de chivo cabezón Ariopsis bonillai (Miles, 1945). Con base en estas capturas, se estimó la relación tallapeso para hembras y machos en forma separada y en conjunto. Se obtuvieron las curvas de crecimiento según von Bertalanffy en talla y peso para ambos sexos y también los valores preliminares de las tasas de mortalidad natural (M), total (Z) y por pesca (F) Se analiza la variación de estos resultados entre sexos como una función causaefecto, originada por el fenómeno de la incubación oral característico en la especie.

Réseaux et groupes d'appartenance chez les pêcheurs migrants : le cas des wolofs de n'diago (Mauritanie)
Provedor de dados: 20
Autores: Dia, A.D.
L'article situe les conditions historiques d'émergence du phénomène migratoire chez les Wolof de N'Diago et de son autonomisation vis-à-vis de des pêcheurs de Guet-N'dar (Saint-Louis) du Sénégal. Il traite des différents réseaux et groupes d'appartenance qui constituent des lieux et modes d'affirmation et d'expression des processus identitaires manipulés à des fins stratégiques d'accès aux ressources de la pêche. Par ailleurs, les phénomènes d’identification à un espace géographique institutionnel sont éclairé à partir d'une approche conceptuelle, bilatéralité des références. Ce qui permet de saisir les conditions particulières des activités de pêches pratiquées dans un contexte de migration et les conséquences de ces migrations sur la différenciation...

Interaction entre les activités de pêche dans le golfe de Gabès
Provedor de dados: 20
Autores: Jabeur, Ch.; Missaoui, H.
Les activités de pêche dans le Golfe de Gabès sont diverses et sont rarement monospécifiques, plusieurs espèces sont pêchées par un même engin (cas du chalutage) et une même espèce est exploitée par plusieurs engins et donc par plusieurs métiers (chalutage et pêche côtière). Les interactions qui existent entre ces métiers sont fortes et sont essentiellement de type compétition sur les ressources et l’espace. Les relations de complémentarité et de substitution sont rares.

Analyse économique des effets induits par la pêche récréative au Sénégal: cas de la Petite Côte et du Sine Saloum
Provedor de dados: 20
Autores: Manel, C. J. P.
La pratique de la pêche récréative dans les eaux sénégalaises constitue une opportunité pour la valorisation des ressources aquatiques du pays. Elle fait partie intégrante de l’offre touristique de plusieurs réceptifs le long du littoral. Cependant, son importance économique n’est pas pour autant bien connue. Pour pallier ce déficit, ce présent mémoire porte sur l’analyse économique des effets induits par la pêche récréative au Sénégal. Il cible, à travers des enquêtes, plusieurs acteurs intéressés par cette activité (voyagistes en France, établissements d’hébergement touristique, centres de pêche, skippers free lance et touristes pêcheurs récréatifs). Les informations qualitatives ont porté sur la perception en général des acteurs, notamment les...

Fishing and poverty levels around Lake Victoria (Kenya)
Provedor de dados: 20
Autores: Abila, R.O.; Omwega, R.N.; Lwenya, C.
Fishing is known to be one of the oldest occupations of mankind and in Lake Victoria (Kenya); it has been largely practiced at artisanal levels. Despite this, poverty amongst the fisher folk remains high. Why the fisher folk remain in perpetual poverty was the key research question for this study. Sampling was conducted on 12 landing beaches between June and August 2004. Data was obtained using survey questionnaires; personal interviews were made using open-ended questions and beach observations. Results from this study indicates that 179 fishers sampled earned an average income of Ksh. 107,063 each in a year with modal income of Ksh. 57,600 while in a day they earned an average income of Ksh. 518 each with modal income of Ksh. 200. Fishers perceived that...

Técnicas de elaboración y "Curado" de cuerdas de Currican para la pesca en Taganga/Santa Marta, Colombia
Provedor de dados: 20
Autores: Köster, F.; Guerrero, G.A.; Rios, F.
El presente artículo da una descripción detallada de la elaboración y del "curado" de cuerdas de curricán, utilizadas anteriormente para la pesca en Taganga, un pueblo pescador en la costa norte de Colombia. Antes del "curado", estas cuerdas de fibras de algodón y de fabricación industrial, eran o destorcidas o torcidas a mano nuevamente, o tensionadas y envueltas con una cuerda más delgada del mismo material. El "curado" que siguió a estas operaciones se efectuó tanto en una cocción de corteza de las raíces zanconas de mangle, y/o por medio de un frote de estas cuerdas con los hypocotylos del mismo árbol (Rhizophora manglr). Por medio de las técnicas aquí descritas, los pescadores aspiraban a aumentar la resistencia de sus aparejos de pesca en el agua de...

La langouste rose Palinurus mauritanicus de Mauritanie : Biologie, pêche et état du stock
Provedor de dados: 20
Autores: Kojemiakine, A.; Diop, M.
Résumé : La biologie de la langouste rose des côtes mauritaniennes est aujourd’hui bien connue. Nous avons cependant rappelé les traits marquants. Sur le plan de la pêche, de 1963 à 1988, le stock de la langouste rose a connu trois phases d’exploitation. Après une phase de surexploitation entre 1963 et 1970-1971, le stock de langouste rose de Mauritanie a pu se reconstituer grâce à une réduction importante du nombre de langoustiers. Ceci c’est traduit à partir de 1971 par une augmentation sensible des captures et aussi de la PUE. Mais le dédoublement du nombre de ces derniers en 1987 et 1988 a fait chuter les P.U.E de 50% ce qui est un signe d’effondrement du stock à nouveau.

Optimal Management of a Potential Invader:  The Case of Zebra Mussels in Florida
Provedor de dados: 31
Autores: Lee,   Donna J.; Adams,   Damian C.; Rossi,   Frederick J.
Dominant users of Lake Okeechobee water resources are agricultural producers and recreational anglers.  These uses will be directly affected, should the lake become infested with zebra mussels.  We employ a probabilistic bioeconomic simulation model to estimate the potential impact of zebra mussels on consumptive water uses, recreational angling, and wetland ecosystem services under alternative public management scenarios.  Without public management, the expected net economic impact from zebra mussels is - $244.1 million over 20 years.  Public investment in prevention and eradication will yield a net expected gain of +$188.7 million, a superior strategy to either prevention or eradication alone.

Estimating Mixed Logit Recreation Demand Models With Large Choice Sets
Provedor de dados: 31
Autores: Domanski,   Adam.
Discrete choice models are widely used in studies of recreation demand.  They have proven valuable when modeling situations where decision makers face large choice sets and site substitution is important.  However, when the choice set faced by the individual becomes very large (on the order of hundreds or thousands of alternatives), computational limitations make estimation with the full choice set intractable.  Sampling of alternatives in a conditional logit framework is an effective method to limit computational burdens while still producing consistent estimates.  This method is allowed by the existence of the independence of irrelevant alternatives (IIA) assumption.  More advanced mixed logit models account for unobserved preference heterogeneity and...

Provedor de dados: 31
Autores: Bangsund,   Dean A.; Leistritz,   F. Larry.
Macro-economic forces, technological innovations in equipment, abundant wildlife populations, changing participation levels, and land access are all contributing to a changing environment for wildlife managers and outdoor recreationists.  Since the late 1970s, numerous studies have periodically examined hunter and angler spending in North Dakota; however, comprehensive assessments of changes in spending over time have not been conducted.  The purpose of this report was to evaluate changes in hunter and angler spending from 1981 through 2001 and evaluate spending patterns based on selected participant characteristics.    For resident hunters, increasing trends in miles traveled, spending on lodging, and spending on durable goods were observed, while overall...

Whale-watching and Herring Fishing: Joint or Independent Production?
Provedor de dados: 31
Autores: Lee,   Min-Yang A.
The effects of "localized depletion" of a pelagic fishery (herring) on a non-extractive marine activity (tourism) are investigated. Proponents of the localized depletion theory claim that intense fishing effort can lead to areas that are unsuitable for predators like tuna, groundfish, and whales. This leads to poor outcomes for the fishing and whale-watching industries. However, there has been no consensus in the scientific community about the existence of this phenomenon. Localized depletion would be consistent with an economic theory of joint production, in which nearshore herring stocks are an input in production of both herring and whale-watching trips. A unique dataset of daily whale-watching outcomes is combined with fishing effort and oceanographic...

No litoral brasileiro, a legislação costuma regular as práticas pesqueiras segundo o ciclo de vida das espécies-alvo, mas o fato deste não ser coincidente entre as espécies dominantes nas capturas dificulta o manejo em pescarias multiespecíficas. No litoral de Santa Catarina, o defeso aplica-se apenas à pesca de arrasto, e para tal considera o período reprodutivo do camarão sete-barbas, Xyphopenaeus kroyeri. O presente trabalho investiga a incidência da atividade pesqueira sobre indivíduos em reprodução da betara preta, Menticirrhus americanus, espécie comercialmente apreciada e frequente nas pescarias. As amostragens ocorreram em 2006 e 2007, em desembarques do município de Itapoá, norte do Estado (26°00’S; 48°36’W). Calcularam-se os valores de proporção...

Factors that determine the quality of bigeye tuna, caught in the western tropical Atlantic Ocean
Provedor de dados: 45
Autores: Nóbrega,C.C.; Mendes,P.P.; Mendes,E.S.
Tuna are highly prized in Oriental cuisine, and the bigeye tuna (Thunnus obesus) is of great commercial importance. Quality is assessed by the tuna meat quality, freshness, texture and fat, which can be altered by factors inherent to capture, such as days of onboard storage, months of the year, whether the catch was living or dead, fish weight and year. These factors were correlated to identify those that affect quality. We obtained data from nine vessels, from January 2007 to April 2010, creating an information bank of 21,908 bigeye tuna. Fish quality and parameters were related using multiple linear regression analysis, in which the variables were included in the model by a stepwise procedure (F&gt;4). We found that live catch, heavier fish and fewer...

The ethnoecological knowledge of fishermen from three coastal lagoons in the northern of the State of Rio de Janeiro, Brazil
Provedor de dados: 49
Autores: Lopes,Alexandre Ferreira; Bozelli,Reinaldo Luiz.
The current study investigated the ethnoecological knowledge developed by fishermen through their fishing activities and searched for ways to match such knowledge to empirical data available in the scientific literature. The research involved fishermen from three coastal lagoons in the northern region of the State of Rio de Janeiro, Brazil, who were consulted through semi-structured interviews after the establishment of a trustful relationship over a period of three years with the interviewer. Their knowledge, in addition to its cultural and historical importance to these populations’ survival, in many ways matches scientific studies based on an ethnoecological approach. Their knowledge considers reproductive aspects, feeding habits, and migratory fishing...

ABSTRACT With the purpose of evaluating the status of the lane snapper Lutjanus synagris from limited catch length data from the landings of artisanal fishing catches recorded between 2006 and 2012 in Tayrona and Corales del Rosario y de San Bernardo National Parks, and the Vía Parque Isla de Salamanca, simple indicators and the decision tree methodology were applied. it was observed that this indicator mostly configured a selectivity pattern represented in capture of mayoritary immature specimens (&lt;L  mat ) and a spawning biomass level lower than the target reference point, affecting the natural renewal of L. synagris stocks. Also, it was ratified the degree of overfishing for growth and recruitment to which L. synagris is subjected. Reducing pressure...
