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...

Exploraciones oceanográficas y pesqueras en el Mar Argentino y la región adyacente del Atlántico Sudoccidental (años 1874-1993) OceanDocs
Angelescu, V.A.; Sánchez, R.P..
A detailed analysis is presented of the main contributions both local and international to the fields of oceanography and fishery sciences resulting from exploratory cruises carried out on the continental shelf off Argentina and the adjacent oceanic basin of SW Atlantic over the last 100 years. The end of the 19th century is chosen as starting point for this analysis as it marks the beginning of active marine research by Argentine scientists and an accumulation of information on Antarctic and Subantarctic marine organisms in foreign journals. Mention is also made to previous contributions derived from the classic expeditions and global circumnavigation voyages during the 18th and 19th centuries. Although the aims of those were not always strictly...

La caballa (Scomber japonicus) y las condiciones del ambiente en elárea "El Rincón" 39°40'-41°30'S del Mar Argentino. Septiembre 2000 OceanDocs
Perrotta, R.G.; Viñas, M.D.; Madirolas, A.; Reta, R.; Akselman, R.; Castro Machado, F.; Garciarena, A.D.; Macchi, G.J.; Moriondo Danovaro, P.; Llanos, V.; Urteaga, J.R..
Between September 1st and 6th a research cruise was carried out in the Buenos Aires shelf area of "El Rincon" 39°40'-41°30'S, Argentine Sea SW Atlantic. The total area studied was 2,527.8 nautical mile2. Knowledge of the commercial fleet location at the time of the survey allowed to intensify sampling in a 'miniarea' of 52,8 nautical mile2. The acoustic assessment of chub mackerel (Scomber japonicus) biomass was 49,511.9 t, 94 of which corresponded to this last area. Fish samples coming from fishing trawls included only adult individuals of 240-460 mm total length (TL) and ages ranging 2-11 years. The limit age was estimated at 13 years and natural and total mortality rates at 0.23 and 0.54, respectively. Oceanographic conditions were those typical of the...

Structure démographique des captures des sardiniers Dakarois en 1981 OceanDocs
Lopez, J.; Sow, I..
Ce document de travail présente la structure démographique des captures des sardiniers dakarois en 1981. Les sardiniers basés à Dakar en 1981, étaient au nombre de 15. Les captures réalisés par ces unités, les efforts de pêche mis en oeuvre de même que les rendements obtenus pour chaque espéce ont déjà été récapitulés dans l'archive n°113. Pour les principales espèces débarquées, les distriibutions de fréquence de taille sont présentées mensuellement. Les résultats obtenus sont exploités pour les études de biologie et de dynamique des populations; ils feront l'objet de publications.

Utilización de datos satelitarios en investigaciones oceanográficas y pesqueras en el océano Atlántico sudoccidental OceanDocs
Podestá, G..
The use of satellite data in oceanographic and fishery studies in the SW Atlantic is reviewed. First, terms commonly used in the remote sensing literature are defined. The main satellite sensors used in oceanographic applications are described, and the principles of the remote estimation of two important variables, sea surface temperature(SST)and ocean color, are discussed. The use of remotely sensed data in oceanographic studies of the SW Atlantic is reviewed. Most studies are based on satellite SST fields and describe circulation in the open, particularly near the confluence of the Brazil and Malvinas currents. Due to the limited number of fishery studies based on satellite data in the SW Atlantic, examples from other parts of the world are reviewed....
