| Abstract |
Hauls with a plankton net and a pump, are used to study twice a month, from the surface to the bottom and in the upper layer at 0-4-7-10-15-20 m. A coefficient of correction is applied by comparison with a Van Dorn bottle (standard). Temp is the determinant factor for Acanthodiaptomus denticornis repartition. Distribution of Cyclops abyssorum prealpinus and of Daphnia longispina is determined by trophic conditions and light. In these lakes, the different stages of the development are not generally isolated in the same stratum, they are associated with 1 or 2 stages which have the same physiological requirements, probably to select the same kind of food. Spatio-temporal repartition on the day, for limentic Crustacea is ordered by factors varying slowly: temp of the water and food abundance. |
