A comparative study of hybrid catfish fry in concrete tank fed with fairy Shrimp, Moina macrocopa, Artemia salina and commercial feed

Experiments were conducted to study the culture and use of the fairy shrimp, B. thailandensis as live food for hybrid catfish, Clarias macrocephalus x C. gariepinus. The study aimed to compare the growth performance of hybrid catfish fed with fairy shrimp, Moina macrocopa, Artemia salina, commercial feed and continually fed with commercial feed until harvestable stage. Results indicated that the hybrid catfish fed with fairy shrimp had shown maximum length, final weight gain, daily weight gain and survival rate. The differences were shown on the final weight, daily weight gain and survival rate of hybrid catfish fed previously with fairy shrimps compared to other feeds. However, the food conversion ratio of hybrid catfish previously fed with fairy shrimp was not significantly (p > 0.05) compared to fish fed with Moina, Artemia and commercial feed.
