Density, abundance and extractive potential of the mangrove crab, Ucides cordatus (Linnaeus, 1763) (Brachyura, Ocypodidae): subsidies for fishery management Anais da ABC (AABC)
PINHEIRO,MARCELO A.A.; SOUZA,MARCELO R.; SANTOS,LUCIANA C.M.; FONTES,ROBERTO F.C..
ABSTRACT Ucides cordatus is a relevant fishery resource of Brazilian mangroves and requires legal normative to sustainable use based on stock assessment and management. This study evaluated some population parameters (structure, density, abundance, fishery potential and stock) of this crab species in Brazil Southeast (São Paulo, State), discussing the use of the results to delineate fishery management strategies. Density was monthly evaluated (September 1998 to August 1999), using five sample quadrats of 2x2 m. Density (ind.m-2) was indirectly estimated by counting the opened (with biogenic activity) and closed galleries, and contrasted with flooding level by tides using the vertical distribution of macroalgae in the base of trees. Density of U. cordatus...

Temporal changes in caiçara artisanal fishing and alternatives for management: a case study on the southeastern Brazilian coast Biota Neotropica
Lopes,Priscila Fabiana Macedo; Begossi,Alpina.
This paper describes a case study of the changes in fishing that occurred in a Brazilian coastal community after a 10 year interval (1992-2002). There was a decrease in the mean amount of fish caught daily (from 14 kg to 11.32 kg) and annually (from 4.2 t to 3.4 t) and in the richness of species caught (from 21 to 17 species); there was also a low similarity in the species composition of the fish landings (Morisita-Horn index Ch = 0.24). These changes suggested a decline in the locally exploited fish populations, which probably caused the discontinuation of commercial artisanal fishing. However, the diversity of fish caught by hook and line and purse-seine fishing was higher in the second period, whereas there was no significant difference in the diversity...

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...

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...

Биологическая дифференциация и структура запаса черноморского шпрота sprattus spra ttus phalericus (pisces: clupeidae) IBSS Repository
Зуев, Г. В.; Мельникова, Е. Б.; Пустоварова, Н. И..
Изучали внутривидовую дифференциацию и структуру запаса шпрота из разных районов северо-западной части Черного моря. В качестве популяционных характеристик использованы следующие параметры возрас­тной структуры: общее количество поколений (годовых классов), относительная численность разных поко­лений, средний возраст особей в популяции, средние размеры одновозрастных особей. По трем показателям (из четырех) обнаружены достоверные (уровень значимости ниже 0,05) различия между шпротом из запад­ной (о-в Змеиный) и восточной (у западного и южного побережья Крыма) областей. Полученные результаты позволили уточнить предложенную нами ранее предварительную схему внутривидовой дифференциации и структуры запаса черноморского шпрота [5J, согласно которой данный вид в...

Рыбные ресурсы черного моря: многолетняя динамика, режим эксплуатации и перспективы управления IBSS Repository
Еремеев, В. Н.; Зуев, Г. В..
На основе комплексного анализа многолетней динамики ряда промыслово-биологических показателей пред­принята попытка определить характер и степень воздействия промышленного рыболовства на формирование рыбных ресурсов в Черном море (с начала 70-х годов по настоящее время), дать оценку их современного со­стояния и перспектив развития, а также выяснить роль обозначенного фактора в антропогенной перестройке экосистемы бассейна. Главной причиной катастрофического сокращения черноморского вылова в 1989 г. следует считать последовательное сокращение промыслового запаса, начиная с 1979 г., в результате посто­янно нараставшей интенсивности рыболовства. На это указывают: 1) наличие тесной отрицательной корре­ляционной связи (г = -0,898) между величиной запаса и...

Incidences des épisodes d'efflorescences de micro algues toxiques sur les écosystèmes et sur les pêcheries de coquillages en baie de Douarnenez ArchiMer
Thebaud, Olivier; Veron, Gerard; Fifas, Spyros.
The commercial fishery for wedge clam, or telline (Donax trunculus) in the bay of Douarnenez in France started in the early 1980ies. During twenty years, the activity has developed, from an opportunistic fishery, into a regular fishing enterprise for 36 fishermen, who derive from it most, if not all, of their revenue. The fishery is nowadays strictly regulated. It is subject to natural variations in the productivity of clam stocks, in relation with meteorological conditions which can strongly affect the stocks. The bay of Douarnenez has been experiencing regular blooms of harmful algae, both of species leading to shellfish poisoning for human consumption, such as Dinophysis (Diarrhoeic Shellfish Poisoning) and Pseudo-nitzschia (Amnesic Shellfish...

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...

Understanding consequences of adaptive monitoring protocols on data consistency: application to the monitoring of giant clam densities impacted by massive mortalities in Tuamotu atolls, French Polynesia ArchiMer
Georget, Stephane; Van Wynsberge, Simon; Andrefouet, Serge.
During long-term monitoring, protocols suitable in the initial context may have to change afterward because of unforeseen events. The outcome for management can be important if the consequences of changing protocols are not understood. In Tuamotu Archipelago atolls, French Polynesia, the density of giant clams (Tridacna maxima) has been monitored for 12years, but massive mortalities and collapsing densities forced to shift from a line-intercept transects and quadrats (LIT-Q) method to a belt-transect (BT) method. We investigated with a simulation approach the conditions (density, size structure, aggregation of giant clam populations) under which the two methods provided different results. A statistical model relating the BT density to the LIT-Q density was...

Les prises accessoires de la pêcherie de civelles (Anguilla anguilla) dans l'estuaire de la Loire en 1987 ArchiMer
Guerault, Daniel; Desaunay, Yves; Bellois, Pierre; Grellier, Patrick; Robin, Jean-paul; Robineau, Brigitte.
A survey of the glass-eel fishery in the Loire estuary in 1987 (265 boats, 117 tons gasseel, 13733 fishing trips) showed that 16 fishery species constitute the by-catch (49,3 million individuals, mainly juveniles, among which 98 % consist in flounder, sprat and brown shrimp). The analysis of catches in space and time leads to proposaIs for Iimiting the impact during the last fishing weeks. Taking into account the naturai mortality rates of the concerned juveniles, an attempt is made to estimate the actuai impact of the glasseel fishery, after a delay. Only 10 % of the caught brown shrimps wouid have been recruited in the summer shrimp fishery. Up to 85,5 to 97,6 % of juvenile fishes would have disappeared during the following year by natural mortality.

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...
