Abstract

This experiment was conducted to increase the resistance of tiger barb (Capoeta tetrazona ) against environmental stress by
feeding brackish water Gammarus sp. Powder as supplementary diet in three levels (25%, 50% and 75%) and three replicates
pe group compared to control group for 60 days. fishes was fed with 4 diet treatment containea of: 100% artificial diet
(control group), 25% brakish water gammarus and 75% artificial diet, 50% brakish water gammarus and 50% artificial diet
and 75% brackish water gammarus and 25% artifical diet. At the end of experiment, the group that was fed with 25%
brackish water gammarus powder and 75% artificial food in exposed to pH=3/8, temperature=15c and deficiency of oxygen
hat a significant higher for survival than other groups. At the results obtained, it can be suggested that using of 25% brackish
water Gammarus powder with artificial diet SFT00 for rainbow trout is suitable for production of highly quality ornamental
tiger fish.
