Performance growth and survival of Hemibagrus nemurus with probiotic application on aquaponics

Abstract

Hemibagrus nemurus is a freshwater catfish commodity that has high economi value and favored by the community. The purpose of study was to evaluate the growth and survival of Hemibagrus nemurus in aquaponics with the application of probiotics. The research was conducted in Sukawening Dramaga Bogor. Using 6 units of tarpaulin ponds measuring 20 x 3.0x 0.8 m filled with 3 M 3 of water, each pool is equipped with an aquaponics unit with an upstream system using lettuce and eggplant. The experiments, namely using probiotics and without using probiotics with 3 replication. The test fish used is 16.5 sd 0.2 g/individu The probiotics used at a dose of 10 ml/M3. Given every 5 days. Fish were given commercial feed of 4 % at 50 days rearing and then 3% until the end of the study with feeding times/day (morning and afternoon). The test parameters were SGR, survival, absolute weight, FCR and water quality. The result showed that the application of probiotic RIFA can increase the growth and survival of the fish, improve water quality and increase plant productivity.
