Production of Daphnia for Freshwater Nursery Rearing of Cultivable Fishes

Abstract

Aquaculture producing the cheapest protein and good source of nutritional food for the human nutrition. However, intensification of aquaculture systems requires supply of high quality seed which indirectly influenced by the supply of live feed. Mass production and supplementation of live feed play a vital role in larval nutrition of aquaculture hatchery practices. The newly hatched larvae are highly relying on live feed which provides nutrients for growth and physiological activities. The Cladoceran like Moina and Daphnia spp. etc. have good source of nutritional food for many cultivable fishes. Daphnia is an inevitable live feed used in freshwater aquaculture. The impotence of commercial feed at early larval culture makes daphnia as potent live feed in many freshwater fish hatcheries. Therefore, the insemination of daphnia culture and their nutritional make up could help the hatchery people to perform well in the near future.
