Abstract


Catfish is one of the freshwater commodities whose demand continues to increase in Indonesia. Intensive cultivation is done to meet market demand. Intensive cultivation is done by optimizing stocking density. The aim of this research was to know the effect of different density on feed productivity, growth, feed conversion ratio (FCR) and survival of catfish dumbo fry (Clarias gariepinus, Burch) in biofloc and nitrobacter media. This study used a completely randomized design (RAL) with 6 treatments and 3 replications. The test animals
used catfish dumbo (Clarias gariepinus, Burch) with an average weight of 0,6 ± 0,1g and an average length of 4 cm. Catfish dombo seeds are kept in tarpaulin ponds 2 m in diameter with water volume ± 1 m3 for 45 days and feeding 3% of biomass weight. The results showed that the different density of stocking
in biofloc and nitrobacter media had increase on productivity, specific growth rate, feed efficiency and no significant effect on the survival of catfish dumbo fry.
