| Summary: | The diversification of marine finfish aquaculture has identified a requirement for live foods other than the traditional rotifer and brine shrimp species. As copepods constitute a natural component of the diets of larval fish, three species were isolated and their life cycle, environmental tolerances, and productivities investigated. Preliminary trials were also conducted feeding them to larval finfish. The temperate harpacticoid Tisbe species and the tropical cyclopoid Apocyclops dengizicus were chosen for these trials as a result of their persistence in aquaculture environs and apparent tolerance of a wide range of environmental conditions. Both Tisbe sp. and A. dengizicus populations in culture were found to tolerate temperatures and salinities over the ranges of 10 °C to 35 °C and 25 %o to 70 %o respectively, and were well accepted by first feeding larvae of test fish species. Tisbe sp. populations maintained at 20 °C and 35%0 and fed a mixed algal diet of Tetraselmis sp. and Isochrysis ... |
