A comparison of economic performance in the fisheries sector: A short- and long-term perspective ArchiMer
Le Floc'H, P.; Daures, Fabienne; Brigaudeau, Cecile; Bihel, J..
Indicators of the economic performance of fishing vessels are frequently computed in various countries. In this paper, we use different types of information to assess capital value and the economic performance of fishing vessels. On the one hand, field surveys provide technical and financial information on the main components of fishing capital. On the other hand, book values are given in bookkeeping databases. Both sources of information on fishing capital are used for the same set of vessels, namely the commercial fishing fleet of the French region of Brittany. Based on these two sources, measures of economic performance can be produced for the short term using gross surplus; and for the long term including the cost of capital. The measures of...

A Dynamic Model of Mesh Size Regulatory Compliance AgEcon
Akpalu, Wisdom.
This paper employs a dynamic model for crimes that involve time and punishment to analyze the use of a net with illegal mesh size in a management regime where each community claims territorial use right over a fishery but has a discount rate that may differ from the social discount rate. The equilibrium stock and harvest levels are found to be much lower if the regulation is violated. Moreover, the optimal penalty for violation must be decreasing in the shadow cost of taking the risk to fish illegally, and increasing the risk of punishment increases the equilibrium stock level.

A new approach to recruitment overfishing diagnosis based on fish condition from survey data ArchiMer
Ordines, Francesc; Lloret, Josep; Tugores, Pilar; Manfredi, Chiara; Guijarro, Beatriz; Jadaud, Angelique; Porcu, Cristina; Gil De Sola, Luis; Carlucci, Roberto; Sartini, Marina; Isajlovic, Igor; Massutti, Enric.
A new approach to recruitment overfishing diagnosis is presented. We hypothesize that condition of recruits should increase when recruitment failures are caused by fishing activity. This would be a consequence of the increase in trophic resource availability, because the population is smaller than that which the ecosystem could support. Temporal series of hake recruit condition were calculated from MEDITS survey data collected in Mediterranean geographical sub-areas (GSAs) 1, 6, 17 and 19 from 1994 to 2015. Multiple linear regressions were used to analyse the relationship between mean annual condition and abundance of recruits and climatic indices in each GSA. Significant correlations were only detected in GSA 6, where 69% of condition variability was...

An end-to-end model to evaluate the sensitivity of ecosystem indicators to track fishing impacts ArchiMer
Halouani, Ghassen; Le Loc'H, François; Shin, Yunne-jai; Velez, Laure; Hattab, Tarek; Romdhane, Mohamed Salah; Ben Rais Lasram, Frida.
In order to assist fisheries managers, ecological indicators are needed to evaluate the effects of fishing activities on marine ecosystems and to improve communication of these effects in both public and scientific contexts. Finding appropriate indicators is challenging given the complexity of marine food webs as well as the ecosystem response to fishing pressure. In this study, an end-to-end model developed in the Gulf of Gabes ecosystem (Tunisia) was used to compare the performance of a set of ecosystem indicators in assessing the impact of fishing. This end-to-end model aimed to represent the ecosystem functioning by coupling two existing sub-models, the multispecies individual-based model OSMOSE, representing the dynamics of exploited species and the...

Analyses de données halieutiques (séries historiques) sur le thon germon, Thunnus alalunga, en Atlantique Nord-est ArchiMer
Patucca, Audrey.
The works carried out during this course (March-August 2015) alowed to correct the datasets and to study the variation in catches of albacore tuna from 1967 to 2014 (except for the years 1987 to 1990) based on 3 gears: the trolling line, the line with cane and the pelagic trawl. Simultaneously, key ICCAT delivred was provide information to expert groups, with a view to defining fishing quotas. Catches released and fishing effort (defined by the number of vessels and the time spent at sea) have varied considerably over these 50 years, and have been increasing in recent years, after having decreased sharply. Fishing today is concentrated on the edge of the continental shelf, whereas it was very oceanic before. It is mainly juveniles that are caught, while...

Capacity reduction, quota trading and productivity: the case of a fishery AgEcon
Fox, Kevin J.; Grafton, R. Quentin; Kompas, Tom; Che, Tuong Nhu.
We present the first ex post study that quantitatively analyses the effects of a licence buyback and enhanced quota trading on the profitability and productivity of individual vessels in a fishery. Using firm-level data and a profit index decomposition method, we find that small and large vessels and three different trawler fleets all experienced substantial productivity gains in the year immediately following a licence buy-back and the establishment of a quota brokerage service. The apparent ongoing benefits of the buy-back and increased quota trading over the sample period are in stark contrast to the generally unfavourable long-term outcomes commonly associated with vessel buy-backs in input-controlled fisheries.

Contribution à l'étude de la crevette rose Palaemon serratus (Pennant) : Exploitation, Biologie, Elevage, Epidémiologie ArchiMer
Campillo, Albert.
This these is the result of several years of investigations conducted on the common prawn Palaemon serratus in the Roscoff (northern Brittany) and Yeu (bay of Biscay) sectors of the French Atlantic coast. Following a description of the fishery and fishing strategies, it deals with the species biological aspects, focusing on growth, lifespan, sex-ratio and breeding. Hypotheses on the reasons for apparent variations in interannual abundance are drawn up and compared with field observations. The second part is devoted to production experiments in a controlled environment (hatchery), explaining how larvae are obtained and their development and survival with respect to food, density and physical parameters like salinity and temperature. The link between...

Cumulative Effects of Coastal Habitat Alterations on Fishery Resources: toward Prediction at Regional Scales Ecology and Society
Jordan, Stephen J; United States Environmental Protection Agency, Gulf Ecology Division; jordan.steve@epa.gov; Smith, Lisa M; United States Environmental Protection Agency, Gulf Ecology Division; smith.lisam@epa.gov; Nestlerode, Janet A; United States Environmental Protection Agency, Gulf Ecology Division; nestlerode.janet@epa.gov.
Coastal habitat alterations such as the loss of submersed aquatic vegetation (SAV) and hardening of shorelines could have cumulative effects on valuable fishery resources. To investigate this effect, we developed a multiscale modeling framework for blue crab (Callinectes sapidus) in the northern Gulf of Mexico. Areal coverage of shoreline land cover and SAV for Mobile Bay, Alabama, were combined with information from small-scale biological studies and long-term, large-scale commercial fishery data to model the potential effects of marginal habitat losses on the blue crab fishery. We applied stochastic variation in annual recruitment to the fishery to estimate probabilities for sustainable harvests under scenarios of habitat loss. The simulations suggested...

Development and characterization of 20 polymorphic microsatellite markers for Epinephelus marginatus (Lowe, 1834) (Perciformes: Epinephelidae) using 454 pyrosequencing Genet. Mol. Biol.
Vaini,Jussara Oliveira; Mota,Kenneth Gabriel; Ojeda,Alejandra Paola; Barreiros,João Pedro; Moreira,Renata Guimarães; Hilsdorf,Alexandre Wagner Silva.
Abstract The dusky grouper, Epinephelus marginatus, is a well-known and widespread marine fish assessed as endangered by the International Union for the Conservation of Nature. Analyzing the genetic diversity of this species is, therefore, of utmost importance and necessary for conservation purposes. Microsatellites are molecular tools with advantages that are ideal for population analyses. This study provides the first set of species-specific microsatellite loci for E. marginatus that can be applied when assessing both intra- and interpopulation genetic variation. Twenty microsatellite loci were isolated and characterized for the dusky grouper by genotyping 20 individuals obtained from the North Eastern Atlantic Ocean (n = 4) and from the South Western...

El cluster pesquero de Chimbote: acción conjunta limitada y la tragedia de los recursos colectivos AgEcon
Kuramoto, Juana R..
Chimbote es uno de los principales puertos pesqueros del Perú y alberga una parte importante de las fábricas de harina de pescado del país. Sin embargo, luego de más de cincuenta años de existencia, este puerto está lejos de haberse convertido en un cluster dinámico formado por negocios pesqueros altamente especializados y diversificados. Este trabajo pretende explicar esta situación, usando como tesis que la acción conjunta es primordial en el desarrollo de los clusters dinámicos y que ésta se ve obstaculizada en las actividades económicas que no cuentan con derechos de propiedad claramente establecidos, como es el caso de la pesca de anchoveta. La falta de acción conjunta se aprecia en la persistencia de problemas que afectan la eficiencia colectiva...

Evaluation du stock de palourdes du bassin d'Arcachon ArchiMer
Bertignac, Michel; Auby, Isabelle; Sauriau, Pierre-guy; De Montaudouin, Xavier; Foucard, Julie; Martin, Sophie.
As part of a larger project financed by the European Union programme "Community initiative PESCA" on the study of "small scale fisheries" in Aquitaine (France), an estimation of the stock of clams in the Bassin d'Arcachon has been conducted. A two-stage stratified random sampling survey has been designed. Samples have been collected using a Hamon bottom sampler in 237 locations distributed over 24 km2. The clam Tapes philippinarum, which appeared in the basin following a series of aquaculture experiments in the mid eighties, is now the main species accounting for more than 90% of the abundance and the biomass, largely overcoming the European species Tapes decussata. The mean abundance and biomass (26 clams / m2 et l28g / m2) are above those estimated in...

Évolution de l'écosystème pélagique du Golfe de Gascogne pendant la période 1990-2003. Conséquences sur la capturabilité des espèces ArchiMer
Villalobos, Hector.
Several small pelagic fish species contribute remarkably to world catch. Their populations are, however, characterized by large biomass fluctuations strongly affecting fisheries. The fishing gears and methods used to capture small pelagics have evolved to exploit the highly developed shoaling behavior of these species. Hence, faced to modern fishing this gregarious behavior becomes a disadvantage for fish. Fish behavior may be affected by environmental conditions and by fishing, at the same time that behavior impacts fishing. In this study, we seek to characterize the aggregative systems of small pelagic fishes inhabiting the Bay of Biscay by analyzing "acoustic images", defined as the group of echoes (planktonic layers, shoals, isolated targets) detected...

Findings from an exploratory study on the governance of a French fishery ArchiMer
Tissière, Laurie; Mahévas, Stephanie; Trouillet, Brice.
In marine fisheries science, the application of social sciences and the increasing use of a multidisciplinary approach have enriched fisheries research through new paradigms. The stance on fisheries governance aims to complement bio-economic approaches and to break with the “tragedy of the commons” premise by focusing on the institutions and network actors at the heart of knowledge, representations, actions and decisions systems. Although the French-European context is largely determined by The Common Fisheries Policy, governance levers and an organised network of actors have been identified in demersal and benthic fisheries. In the present study, the observation of dialogue meetings identified the stakeholder strategies and interactions used to activate...

Fishing activity in Northern Rio de Janeiro State (Brazil) and its relation with small cetaceans BABT
Beneditto,Ana Paula Madeira Di; Ramos,Renata Maria Arruda; Lima,Neuza Rejane Wille.
Research on fishing activity at Atafona village, in Northern Rio de Janeiro, Brazil (21°35'S), was carried out between 1987-96 for the purpose of relating it to the accidental capture of small cetaceans and of estimating the relationship between fishing activity and the diet of small cetaceans. Data on fishing operations were obtained at the cold storage plants management, from interviews with fishermen and personal observations. The most representative fishing resources were Xyphopenaeus kroyeri, Micropogonias furnieri, Carcharhinus plumbeus, C. acronotus,and Rhizoprionodon porosus. Gillnets are responsible for the accidental capture of small cetaceans in the region, mainly Pontoporia blainvillei and Sotalia fluviatilis (marine form). Four types of...
