Última Vieira patagonica (Zygochlamys patagonica King & Broderip, 1832): una nueva pesquería en la plataforma continental argentina. 20 Lasta, M.L.; Bremec, C.. Patagonian scallop (Zygochlamys patagonica King Broderip, 1832): A new fishery in the Argentine continental shelf. We present preliminary information on a new fishery of patagonian scallop (Zygochlamys patagonica King Broderip, 1832) in the Argentine Continental Shelf. A research program was conducted jointly by INIDEP and a fishing company during 1995 with the F/V Erin Bruce. The vessel, fishing equipment and processing on board are described. A total of 7235 fishing tows were performed during 246 days at sea. Seven new beds were located between 38º 50' S and 42º 30' S, along the 100-m isobath. Beds are discrete. Differences in the size structure by bed suggest that recruitment consists of sporadic pulses. Proportion of scallops and invertebrate by-catch...

The main life history characteristics, ecology and fishing interest of bivalve and gastropod species from the Argentine Sea are described. Exploited bivalve species are: mussel Mytilus edulis platensis, cholga Aulacomya ater, tehuelche scallop Aequipecten tehuelchus, Patagonian scallop Zygochlamys patagonica. Bivalve species irregularly exploited are: yellow clam Mesodesma mactroides, purple clam Amiantis purpurata, hard shell clam Ameghinomya antiqua and wedge shell Donax hanleyanus. It is also presented information on species of potential interest: clams Eurhomalea exhalbida and Pitar rostratus, half naked pen shell Atrina seminuda, 'geoduck' Panopea abbreviata, razor shells Solen tehuelchus, Ensis macha, Tagelus plebeius, and flat oyster Ostrea...

Résumé : En 15 jours de pêche expérimentale, un caseyeur japonais a pêché près de 40.000 kg de crabe profond (Geryon maritae) représentant 12.032 kg de produit fini sous forme de farcis et pattes. Le rapport Capture/Produit fini a été estimé à 3, et celui de Poids total du crabe/Poids des pattes à environ 1,7.

Ano: 1995 URL: http://hdl.handle.net/1834/253 Les ressources vivantes exploitables du lac de Bizerte : Etat actuel et potentialités ( première partie) 20 Beji, O.. La production conchylicole du lac de Bizerte reste très faible (une moyenne de 120 t /an) comparée à son potentiel qui a été estimé selon les auteurs et la surface exploitée entre 10000 et 20000(t)/an. Un programme de développement d'entreprises conchylicoles de type familiales, PME et autres est à priori largement justifiable dans le lac de Bizerte et la mer ouverte avoisinante (zone de cap Zebib).La production annuelle moyenne de la pêche est de 86,7 t/an avec une productivité totale de 12,4 kg/ha/an. L’aménagement de la pêcherie, l’introduction d’une aquaculture extensive et l’ensemencement régulier du plan d’eau sont des solutions intéressantes pour améliorer les ressources du lac. La collecte naturelle des algues rouges de type gracilaire n’offre... Tipo: Journal Contribution Palavras-chave: Potential resources; Aquaculture development; Shellfish; Exploitation.

Wetlands that occur in arid and semi-arid areas have unique characteristics and support unique biodiversity. The permanent wetlands are relatively small and isolated by large areas of dry land. There are however, numerous temporary or seasonal wetlands that contain water for only short period in the year. These wetlands contain water, a critical resource for all people, livestock, wildlife and plant life. The availability of fresh water minerals, pasture and other useful products attract humans, thereby making the wetlands to become focal points of economic development and indeed urbanization. The changing lifestyles of resident communities, such as increased focus on subsistence and commercial agriculture and sedentarization as opposed to nomadic...
