Abstract: Breeding of Brachionus Calyciflorus (rotifer), Moina micrura (cladoceran) and Thermocyclops sp. (copepod) on poultry dropping were investigated in mixed condition. The most production per day was obtained in chicken dropping medium (p < 0.05) with in top B. Calyciflorus (973 ± 249 individuals/L), followed M. micrura (126 ± 08 individuals/L) and Thermocyclops sp. (45 ± 19 individuals/L). M. micrura had a higher intrinsic rate (a) and the less duplication time (Td) (a = 0.88 ± 0.05; Td = 1.13 ± 0.07), followed B. Calyciflorus (a = 0.73 ± 0.02; Td = 1.38 ± 0.05) and Thermocyclops sp. (a = 0.21 ± 0.01; Td = 5.08 ± 0.88). The colonization phase ranged 6-12th day for M. micrura and B. calyciflorus and 18-21th day for Thermocyclops sp. Evolution profile and dynamic of populations showed: (1) quickly evolution marked by a peak followed a crash of species rotifer (B. calyciflorus) and cladoceran (M. micrura); (2) more late evolution of copepod (Thermocyclops sp.). In perspectives of culture of life food for larviculture, it result of this experiment that the harvest of zooplankton may be realized 6-12th day when the zooplankton production reached its high level; and rotifers and cladocerans were abundant.
