Feeding of Gammarus lacustris Sars under different conditions of habitation [Translation from: [Trophic relations of freshwater invertebrates.] (ed. G. G. Vinberg) pp.94-98. Leningrad, Zool.Inst.AN SSSR, 1980]

The amphipod Gammarus lacustris, a regular representative of lacustrine communities, often plays a significant role in the transformation of matter and energy. The object of the present work was to clarify the quantitative side of the feeding of the amphipod under different conditions of habitation. Experimental works on determination of the rate of consumption of food and its dependence on body-weight were carried out in the summer periods 1975-1978 on three water-bodies of the Krasnoyarsk region, of different conditions of habitation for the amphipods.

Relations longueur-poids de 43 espèces de poissons capturées dans les lagunes ivoiriennes

Since 1974 we have been collecting statistics on the main fishing gears in the ivorian lagoons. In order to get good estimation of the catches, it is often more convenient to measure the fishes and to convert this data into weights through a length-weight relationship. In this work we computed this relation for 43 species found in the Aby and Ebrié lagoons.
