Aislamiento de Microsatélites y flujo Genético en Dosidicus Gigas (D'Orbigny, 1835) entre el Golfo de California y La Costa Occidental de La Península de Baja California, México OceanDocs
Millán, A.M..
El calamar gigante, Dosidicus gigas (D'Orbigny, 1835) es una especie semioceánica y nerítica endémica del Pacífico Oriental, distribuida desde el norte de California E.U.A (43º N) hasta el sur de Chile (20°S), incluyendo el Golfo de California. Habita aguas desde la superficie hasta 1000 metros de profundad. Particularmente dentro del Golfo de California (México), es considerado uno de los recursos pesqueros más importantes, sin embargo el manejo de la pesquería de éste cefalópodo enfrenta varias dificultades entre las que se encuentran: un corto ciclo de vida, tasa de crecimiento desigual y falta de caracteres morfométricos y/o merísticos debido a la extrema plasticidad morfológica. Con el fin de determinar si existe estructura genética poblacional en D....

Características ecológicas del pulpito Octopus Tehuelchus en tres ambientes del golfo San Matías OceanDocs
Storero, L.P..
Coastal marine ecosystems are highly variable and the inherent biotic and abiotic factors of these environments can influence the bio-ecological characteristics of the living cephalopods. The presence of the small octopus “pulpito” Octopus tehuelchus in the coastal environments of San Matías Gulf has been exploited by artisanal fishermen for more than 60 years. The aim of this study is to evaluate the variations in the life cycle of the pulpito, and the factors that could account for these variations in three different coastal environments of San Matías Gulf, with differences in the physical, ecological and fisheries characteristics. This study was developed in San Antonio bay, El Fuerte and Islote Lobos. Monthly samplings (October 2005-2007) in the...

Contribution de la recherche à l'amélioration des moyens d'existence durables des communautés de pêche artisanale: étude de cas du Sénégal OceanDocs
Moustapha, Déme; Ibrahima, Seck; Diébel, Sarr; Moustapha, Thiam; Karim, Dahou; Mamadou Diop, Thioune; Aliou, Sall.
Jusqu'à une période récente, le choix et l'exécution des thèmes de recherche se faisaient sans aucune concertation ni coordination avec l'administration, les professionnels et les ONG. Le processus actuel tient davantage compte de l'ensemble des acteurs de la pêche, mais si les professionnels sont consultés lors de l'élaboration de mesures, leur participation se réduit souvent à une simple validation, sans qu'ils puissent intervenir dans l'exécution proprement dite. Ce projet vise à mieux rendre compte des capacités et programmes de recherche du point de vue des politiques nationales relatives à la pêche. Le rapport suivant synthétise quatre notes sur les conditions de vie des groupes évoluant dans la pêche artisanale, la fourniture de services de...

Description de la pêcherie démersale céphalopodière en Mauritanie (1990 – 1992) OceanDocs
Inejih, C.A.O..
Résumé : Le présent article donne une description de l’évolution des paramètres descripteurs de la pêcherie de céphalopodes. Il utilise les statistiques de pêche du CNROP. Les paramètres décrits sont l’effort (nombre de licences, caractéristiques physiques des bateaux, jours de pêche), les captures et les prises par unité d’effort. Les débarquements totaux ont enregistré une hausse atteignant 42000 tonnes en 1992. Cette hausse est due à celle des rendements importants observés pour le poulpe ; ceux des poissons ont diminué continuellement depuis 1990, notamment chez les glaciers. L’effort, en jour de pêche, a enregistré une baisse progressive pour les congélateurs. Par contre, il a presque doublé de 1990 à 1991 chez les glaciers. Les deux modes de...

Diagnostic des pêcheries du poulpe (Octopus vulgaris) dans les eaux sous juridiction sénégalaise: Rapport définitif OceanDocs
Les seiches, poulpes, calmars et nautiles forment la Classe des Céphalopodes de l’Embranchement des Mollusques de grande taille, exclusivement marins. Leur croissance est rapide, leur arrivée à la maturité sexuelle précoce et leur durée de vie courte. Le poulpe a une très large aire de distribution incluant les eaux maritimes tropicales. Elle abonde surtout en Méditerranée, dans les eaux japonaises (Océan Pacifique) et dans l’Atlantique Centre-Est qui s’étend du Maroc à l’Angola. La pêche du poulpe s’est développée au large du Sahara dans les années 1960. Son importance dans la zone du COPACE notamment, au Maroc, en Mauritanie et au Sénégal, s’expliquerait par la raréfaction de ses prédateurs potentiels (Serranidés, Sparidés). Au Sénégal, elle est...

Ommastrephes bartramii: a potential target for the squid fishery in the Southwest Atlantic OceanDocs
Brunetti, N.E.; Ivanovic, M.L..
Six exploratory cruises on board of the Japanese RV "Shinko Maru N°3" were carried out between 1997 and 2002 to obtain data on red squid (Ommastrephes bartramii)in the oceanic area of the SW Atlantic off Argentina and Uruguay (33° S-42° S/43° W-55° W). Between 10 and 32 jigging stations were performed each year during the night at depths of 80-200 m. Positive catches were registered in the whole area investigated with yields ranging between 0.01 and 2.03 kg/ (hour*line)and 0.001-2.26 individuals/(hour*line). Total catches oscilated between 1,426 kg in 2002 and 2,825 kg in 2000 and sea surface temperature at the fishing stations between 7.5° C and 24.5° C. Yields higher than 1 individual/ (hour*line)were registered at surface temperatures of 22° C-24° C....

Pesquerías de pulpos OceanDocs
Re, M.E..
The species composition, population structure, seasonality in catches and fishing of octopuses along the Argentine coast are described from available statistical data and capture samplings. Three species of octopuses, Octopus tehuelchus, Eledone massyae and Enteroctopus megalocyathus are caught. An artisanal intertidal fishery of O.tehuelchus occurs mainly in summer, from November-December to March-April in the North Patagonian coast, especially in the San Matias Gulf, by hooks. E.massyae is caught by coastal trawlers all around the year but mainly in winter and spring in Mar del Plata and Necochea areas. E.megalocyathus is caught by hooks in the intertidal zone and by diving in the subtidal zone, from the North Patagonian gulfs (March to November)to the...

Reproductive biology of red squid (Ommastrephes bartramii) in the Southwest Atlantic OceanDocs
Brunetti, N.E.; Ivanovic, M.L.; Aubone, A.; Pascual, L.N..
Red squid (Ommastrephes bartramii) samples were collected during six exploratory cruises carried out in the Southwest Atlantic region off Argentina and Uruguay (33° S-42° S; 43° W-55° W) during summer-autumn of the period 1997-2002 on board the japanese jigger “Shinko Maru N° 3” under a joint research programme approved by Japan and Argentina. Size ranges of the squids analyzed were 10-40 cm mantle length (ML) for males and 12-49 cm ML for females. Two groups of squids were identified: smaller and larger than 20 cm ML. The group under 20 cm ML was characterized by the presence of immature squids and a sex ratio of around 1:1 in the whole study area. The squids of more than 20 cm ML included from immature to mature individuals. The mean sizes, proportion of...
