Analyse des resultats et des comportements economiques des entreprises de peche artisanale ArchiMer
Catanzano, Joseph; Gilly, Bernard; Lantz, Frederic; Durand, M.h..
(Not controled OCR) The economic results of artisanal fishing enterprises are investigated through a sample of 300 to 700 artisanal vessels for which account books are available from 1983 to 1986. The use of economic (such as added value) and financial ratios (solvency and financial autonomy) leads to the identification of four groups of firms. A rough classification has been identified from gears used and areas. Over the period, financial rentability and autonomy show obvious damaging that underlines the relevance of a (current) analysis on the impact of public subsidies on the enterprises behaviour.

Assessment of sábalo (Prochilodus lineatus) fisheries in the lower Paraná River basin (Argentina) based on hydrological, biological, and fishery indicators Neotropical Ichthyology
Baigún,Claudio; Minotti,Priscilla; Oldani,Norberto.
This study assesses the change in fish exploitation patterns of the sábalo fisheries of the lower Paraná River basin based on hydrological, biological, and fishery indicators. From historical catch records, we recorded a shift from a lightly and moderate exploited status before 2001 to a heavily exploited one, as a result of the development of sábalo exports from 2001 onwards. Channel and floodplain connectivity indices demonstrated that the Paraná exhibited highly favorable hydrological conditions between 1972 and 1999 but more adverse conditions from 1999 to 2009, as a consequence of flood pulses reduction coincident with a fishing mortality increment. A total catch of 15,000 tons, including local consumption, regional market, informal sales, and...

Bony fishes (Teleostei) caught by small-scale fisheries off central to south coast of São Paulo State, Southeastern Brazil Biota Neotropica
Motta,Fabio Santos; Rosa,Marcos Rogério; Namora,Rafael Cabrera; Gadig,Otto Bismarck Fazzano.
Small-scale fisheries have a great socioeconomic importance in Brazil. Different regional characteristics along the coast, mostly related to landing sites, equipment used, and targeted species, renders its assessment and monitoring difficult. The aim of this paper is to present a list of species of bony fishes (Teleostei) caught by artisanal fisheries along the São Paulo coast, southeastern Brazil and to provide comments on the relative abundance and conservation status of those species. A total of 315 fishing fleet landings were surveyed, and 106 species distributed among 38 families were recorded. Sciaenidae and Carangidae were the most frequent families in species number. The southern king weakfish, Macrodon atricauda, was the most abundant species,...

Changes in the catch composition of artisanal fisheries attributable to dolphin depredation in a Mediterranean marine reserve ArchiMer
Rocklin, Delphine; Santoni, Marie-catherine; Culioli, Jean-michel; Tomasini, Jean-antoine; Pelletier, Dominique; Mouillot, David.
There is increasing evidence from previous studies, and from fishers' observations, that coastal dolphins use fishing nets as an easily accessible feeding source, damaging or depredating fish caught in the nets. This study investigates the impact of dolphin depredation on artisanal trammelnets by analysing the catch composition of 614 artisanal fishing operations in the Bonifacio Strait Natural Reserve (France). Common bottlenose dolphins (Tursiops truncatus) attacked, on average, 12.4% of the nets and damaged 8.3% of the catch. However, attacked nets were characterized by statistically significantly higher catch per unit effort than unattacked ones. Catch composition also differed significantly after dolphin attacks; bentho-pelagic fish were more...

Des modèles et des indicateurs pour évaluer la performance des Aires Marines Protégées pour la gestion des zones côtières. Application à la Réserve Naturelle des Bouches de Bonifacio ArchiMer
Rocklin, Delphine.
These last decades have been characterized by a great development of fishing techniques, contributing to the overexploitation of numerous marine fish stocks. In order to limit this collapse and to restore impacted communities, the implementation of management measures was necessary. Marine Protected Areas (MPAs), initially developed to protect remarkable habitats and associated biodiversity, are more and more used as a tool for spatial management of fishing activities, by adult export and/or larvae migrations from protected zones to surrounding fisheries. The aim of this PhD was to use indicators and predictive models for evaluating the impact of the Bonifacio Strait Natural Reserve (Corsica) implementation on fish communities and the benefits of such...

Early stages of snapper-grouper exploitation in the Caribbean (Bay Islands, Honduras) ArchiMer
Gobert, Bertrand; Berthou, Patrick; Lopez, E; Lespagnol, Patrick; Turcios, Maria Dolores Oqueli; Macabiau, Christophe; Portillo, Pedro.
In the Caribbean, snappers (Lutjanidae) and groupers (Serranidae) are often heavily exploited by artisanal or industrial fisheries. This paper analyzes the catches of an artisanal fishery selectively targeting these species with a moderate fishing pressure in the Bay Islands (Honduras), and discusses the implications on the understanding of the early stages of development of reef fisheries. Although snappers and groupers are targeted with handlines and spearguns in the whole archipelago, the differences in species diversity and size structure of the catch reveals various exploitation patterns. In most areas, a depletion is observed for the most vulnerable snapper and grouper species, and most other species are mainly exploited in their juvenile phase;...

Fish wariness is a more sensitive indicator to changes in fishing pressure than abundance, length or biomass ArchiMer
Goetze, Jordan S.; Januchowski-hartley, Fraser A.; Claudet, Joachim; Langlois, Tim J.; Wilson, Shaun K.; Jupiter, Stacy D..
Identifying the most sensitive indicators to changes in fishing pressure is important for accurately detecting impacts. Biomass is thought to be more sensitive than abundance and length, while the wariness of fishes is emerging as a new metric. Periodically harvested closures (PHCs) that involve the opening and closing of an area to fishing are the most common form of fisheries management in the western Pacific. The opening of PHCs to fishing provides a unique opportunity to compare the sensitivity of metrics, such as abundance, length, biomass and wariness, to changes in fishing pressure. Diver-operated stereo video (stereo-DOV) provides data on fish behavior (using a proxy for wariness, minimum approach distance) simultaneous to abundance and length...

La pêche artisanale des années quatre-vingt en France ArchiMer
Catanzano, Joseph; Lantz, Frederic; Vernier, C; Allard, M.o.
The artisanal fisheries industry has experienced a major development over the 80's: technology has improved and ship building costs have increased. The firms' economic behaviour and financial performances have shown that the marginal profitability of capital is lower for large units than for small units, the latter being used by coastal fisheries. Overall, conclusions on the financial situation of the industry must be qualified. Public intervention has materialized through (1) an increasing amount of state aids supporting modernization investment (Brittany being the most supported region), (2) more political and financial involvement of regions as a result of more administrative and decision making responsibilities being devolved to them, (3) the...

Local ecological knowledge is not a useful source of information concerning impacts caused by non-native Nile tilapia on fishery stocks - doi 10.4025/actascibiolsci.v35i3.18418 Biological Sciences
Brasil, Jandeson; Universidade Federal do Rio Grande do Norte; Bastos, Fernando; Universidade Federal do Rio Grande do Norte; Mourão, José da Silva; Universidade Estadual da Paraíba.
Exotic freshwater fish can have deleterious effects on local biodiversity, although these impacts often only become apparent many years after the introduction. Local Ecological Knowledge (LEK) may be a useful source of information in situations where formal technical studies are insufficient, but few works have examined the reliability of information generated through this approach. We examined the reliability of LEK by investigating the impacts of Nile tilapia on fishery stocks in an artificial reservoir in northeastern Brazil. We gathered LEK from 29 experienced fishermen and then confronted this information with official fishery statistics from the same site. Twenty-two fishermen stated that total catch in the Gargalheiras Reservoir had declined over...

Local ecological knowledge of fishers about the life cycle and temporal patterns in the migration of mullet (Mugil liza) in Southern Brazil Neotropical Ichthyology
Herbst,Dannieli Firme; Hanazaki,Natalia.
This research investigates local ecological knowledge of fishers in communities along a latitudinal gradient in the coast of the Santa Catarina State, regarding the life cycle of mullets Mugil liza (migration, feeding, and reproductive behavior). Our sampling encompassed eight Santa Catarina coastal cities (nine artisanal fishing sites) and engaged 45 key informants (28- 86 years of age) through semi-structured interviews from August/2011 to March/2012. This fish species feeds and grows in lagoon and estuarine systems, migrating to the sea for reproduction, and spawning. Fishers acknowledged the Patos Lagoon and the Plata River as the main source of mullet schools. Migration occurs from South to North and the routes vary according to climatic and...

Local ecological knowledge on the goliath grouper epinephelus itajara (teleostei: serranidae) in southern Brazil Neotropical Ichthyology
Gerhardinger,Leopoldo Cavaleri; Marenzi,Rosemeri Carvalho; Bertoncini,Áthila Andrade; Medeiros,Rodrigo Pereira; Hostim-Silva,Maurício.
The goliath grouper Epinephelus itajara is a large sized (> 400 kg) and critically endangered marine fish, which is protected in many countries, including Brazil. Through the application of semi-structured interviews, we investigated the local ecological knowledge of seven fishermen specialist on catching E. itajara from the Babitonga bay, Santa Catarina, Brazil. Local long-line fisheries for E. itajara seemed to be a disappearing tradition in the studied site, with a detailed inherent local ecological knowledge system, which is also being lost. Our study also showed that fishermen engaged in recent fisheries, such as spear-fishing, can also possess a detailed local ecological knowledge system. Through the analysis of fishermen local ecological...

Reproductive biology of Macrobrachium surinamicum (Decapoda: Palaemonidae) in the Amazon River mouth. Repositório Alice
LIMA, J. de F.; CRUZ, M. C. M. da; SILVA, L. M. A. da.
Macrobrachium surinamicum is an indigenous prawn distributed from the lower Amazon and Tocantins river basins to Venezuela in the Orinoco Delta region. It is common bycatch fauna of Macrobrachium amazonicumartisan fishing in the states of Pará and Amapá. The aim of this study was to investigate aspects on reproductive biology (reproductive period, size of sexual maturity population, fecundity, reproductive output and recruitment) of M. surinamicum from four important areas to artisanal prawn fishing located at the Amazon River mouth (Amapá and Pará). The specimens were captured using 20 handcrafted traps called ?matapi?. A number of 675 prawns were captured, 258 males, 409 females and eight juveniles, resulting in 1:1.6 (Male: Female) sex ratio. The...

Resilience, Social-Ecological Rules, and Environmental Variability in a Two-Species Artisanal Fishery Ecology and Society
Duer-Balkind, Marshall; Department of the Environment, Washington, DC; School of Forestry and Environmental Studies, Yale University, New Haven, CT, USA; marshall@aya.yale.edu; Jacobs, Kasey R.; NOAA Coastal Management Fellow at the Puerto Rico Coastal Zone Management Program, San Juan, PR; School of Forestry and Environmental Studies, Yale University, New Haven, CT, USA; kasey.jacobs@aya.yale.edu; Basurto, Xavier; Duke Marine Lab, Nicholas School of the Environment, Duke University, Beaufort, NC, USA; xavier.basurto@duke.edu.
Social-ecological resilience is an increasingly central paradigm for understanding sustainable resource management. In this study, we aimed to better understand the effect of environmental variability on the resilience of fishery systems, and the important role that social institutions and biophysical constraints play. To explore these issues, we built a dynamic model of the pen shell fishery of the indigenous Seri people in the Gulf of California, Mexico. This model included the dynamics of the two dominant species in the fishery (Atrina tuberculosa and Pinna rugosa), several institutional rules that the Seri use, and a number of ecological constraints, including key stochastic variables derived from empirical data. We found that modeling with multiple...
