A review of 1973 - 1982 Tuna fishing activities within Nigeria's Eez and the options for Nigeria. OceanDocs
Ajayi, T.O..
Examination of published information on temperature, oxygen and other enviromental prefrences of tuna like fishes suggests that the Nigerian EEz should have commercial quantities of fishes. ICCAT historical catch and effort data analysed are confirmatory. given the prevailing low level of maintenance conciousness, initial investmnt and skills required, purse-seine may not be decidedly superior to pole ond line as capture technique. Prefered size of vessel type and gear specific scenarios are described. It appears that fuel costs can attract some of the multinational fleets to Nigeria and that transhipment facilities and a local canery are advantageous.

Aire marine protégée, gestion halieutique, diversification et développement local: le cas de la reserve de biosphère du Delta du Saloum (Sénégal) OceanDocs
Sarr, O..
Cette thèse étudie le problème de la gestion des pêches au sein d’une AMP, en tenant compte du système économique global ainsi que des transformations structurelles qui affectent celui ci, et en diversifiant les critères de gestion. Le cas d’étude est la RBDS (Sénégal). Une enquête de terrain montre que la population de cette localité diversifie ses activités essentiellement entre l’agriculture, la pêche et le tourisme. Une analyse économétrique indique que la démographie, la sécheresse et la baisse du prix de l’arachide sur le marché mondial sont les principales causes de la crise agricole dans la région. Cette crise favorise la diversification vers la pêche. Un modèle théorique étudiant ce processus montre qu’il conduit la pêche à l’équilibre de libre...

Aménagement des ressources halieutiques au Sénégal: partenariat et démarche préventive OceanDocs
Ndiaye, O..
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...

Artes de Pesca 1 (artes de malla): guía didáctica OceanDocs
Costa Labandera, M.N.; Dragonetti Saucero, J.P.; Fernández Amorín, S..
La pesca es una de las actividades humanas más antiguas. Los registros de su práctica se remontan a varios miles de años. Los productos que de ella se obtienen juegan un importante papel en la dieta humana como fuente de proteína animal, minerales y ácidos grasos esenciales, entre otros. La inmensidad del océano y su biodiversidad, dio lugar por mucho tiempo a la creencia de que el mar era una fuente ilimitada de recursos, capaz de sustentar la población humana indefinidamente. Nada parecía alertar sobre la necesidad de usar métodos de pesca racionales, ni sobre las serias consecuencias ambientales que puede conllevar la actividad pesquera. El perfeccionamiento de buques pesqueros y de las técnicas de navegación determinó un explosivo crecimiento de la...

Bases biológicas para la evaluación y manejo de metapoblaciones de loco en la III y IV Regiones OceanDocs
González, J.; Tapia, C.; Wilson, A.; Stotz, W.; Orensanz, J.M.; Parma, A.M.; Valero, J.; Catrilao, M.; Garrido, J..
En la III y IV Regiones las áreas de manejo y explotación de recursos bentónicos (AMERB) se han establecido como la principal herramienta de manejo del recurso loco (Concholepas concholepas). Sin embargo, su aplicabilidad para la administración y aporte en términos del desarrollo sustentable, aunque sugerentes, requieren de una evaluación objetiva, en cuanto al manejo de carácter discreto que se ha establecido para cada AMERB, desconociendo la eventual interacción espacial de las mismas. En este marco, se desarrolla una aproximación para evaluar el desempeño de las AMERBs desde una perspectiva integral bajo un enfoque metapoblacional. Si bien el estudio está orientado a proporcionar la información de campo que permita probar la hipótesis de metapoblaciones...

Características biológicas y de la pesca del savorín Seriolella porosa (Pisces: Centrolophidae) del Mar Argentino OceanDocs
Garciarena, A.D.; Perrotta, R.G..
Length growth parameters were calculated and total length-weight and total length-fork length relationships, which showed no differences between sexes, were fitted for the South Atlantic bream (Seriolella porosa). Length at first maturity was also calculated. The results were as follows: L (mm)= 490.96k years-¹) = 0.154; t0 (years)= -3.915; W(g) = 4*10-6)*TL³.1989; FL(mm) = 0.8917*TL1.0006);L sub 50 (mm)= 290.61. Natural mortality was estimated at 0.274 and limit age at 11 years. Samples were taken during research surveys carried out in 1999 and 2000 in the Argentine Sea (Atlantic SW). Sagittae otoliths of 374 specimen were used for age determination. Total fish length ranged from 226 mm to 550 mm (1-14 years). Commercial landing data of trawl fleets for...

Checklist of marine demersal fishes captured by the pair trawl fisheries in Southern (RJ-SC) Brazil Biota Neotropica
Rotundo,Matheus Marcos; Severino-Rodrigues,Evandro; Barrella,Walter; Petrere Junior,Miguel; Ramires,Milena.
Abstract: Demersal fishery resources are abundant on continental shelves, on the tropical and subtropical coasts, making up a significant part of the marine environment. Marine demersal fishery resources are captured by various fishing methods, often unsustainably, which has led to the depletion of their stocks. In order to inventory the marine demersal ichthyofauna on the Southern Brazilian coast, as well as their conservation status and distribution, this study analyzed the composition and frequency of occurrence of fish captured by pair trawling in 117 fishery fleet landings based in the State of São Paulo between 2005 and 2012. The ichthyofauna consisted of 245 species (81 families, 32 orders and 2 classes). Among the species, 50 species were...

Coral Transplantation and Restocking to Accelerate the Recovery of Coral Reef Habitats and Fisheries Resources Within No-Take Marine Protected Areas: Hands-On Approaches to Support Community-Based Coral Reef Management OceanDocs
Bowden-Kerby, A..
Of the planet’s 600,000 km2 of coral reefs (Jameson et al., 1995), roughly 70-80% are located in developing countries. Many of these reefs are owned or controlled by indigenous fishing communities rather than national or state governments. These rural fishing communities are a primary force of destruction to coral reefs on a global scale (Wilkinson, 1998), therefore their involvement in the management and conservation of coral reefs will be an essential part of reversing coral reef decline....
