| Topics on Lake Victoria limnology, benthic fauna, stock assessment, catch assessment survey, gear selectivity, fisheries ecology, fish parasites and marketing economics are covered. Management and conservation of the lake's fisheries and other aquatic resources are discussed. Dialogue between fishermen, scientists and administrators is stressed, measures to be undertaken are addressed and further research is recommended. |

| Cette étude a pour but de déterminer la structure générale des peuplements d’Annélides Polychètes le long de la côte N-E du golfe de Tunis. Au total, neuf stations ont été échantillonnées et les spécimens récoltés ont été identifiés, pour la plus part, jusqu’au niveau spécifique. Ensuite, des analyses de la classification ascendante hiérarchique ont été réalisées sur les abondances des différentes espèces aux stations étudiées, ce qui a permis de définir trois groupes de stations faunistiquement plus homogènes avec leurs espèces leaders. Parallèlement, les principaux paramètres synthétiques descriptifs de biodiversité (Richesse spécifique, Abondance, Indice de Shannon et Equitabilité) ont été calculés pour chaque groupe ainsi défini, et des analyses... |

| Macrobenthic sampling was carried out during the survey of mussel beds (Mytilus edulis platensis, D'Orb)at the continental shelf of Buenos Aires province (Argentina)(EH-06/93, INIDEP). 47 samples were obtained with a hard bottom dredge between 18 m and 64 m depth;sedimentological samples were also collected in every station. The following descriptors were used: Maxime Dominance, Relative Dominance, Relative Presence (Bouderesque, 1971), Specific Diversity(H')(Shannon Weaver, 1963)and Evenness (J')(Pielou, 1966)Faunistic associations and areas of distribution were defined usingcluster analysis (UPGMA, Q and R modes)(Legendre Legendre, 1979).The community structure of the benthic macrofauna associated to mussel beds was defined for a coastal area between... |
