This book is the result of two years Master research on culture technique of snakehead, Channa striatus in recirculating aquaculture system (RAS). Growth and survival of endangered snakehead Channa striatus were investigated at different diets, feeding frequencies and stocking densities in RAS. The fry fed with trash fish showed significantly higher (p < 0.05) weight gain percentage than those fed with Acetes shrimp and bloodworm. The best FCR value (3.63 ± 0.27) was found in fish fed with trash fish compared to those fed with Acetes shrimp (7.41 ± 0.88) and bloodworm (11.48 ± 1.51). The fr...

The fry fed with trash fish showed significantly higher (p < 0.05) weight gain percentage than those fed with Acetes shrimp and bloodworm. The best FCR value (3.63 ± 0.27) was found in fish fed with trash fish compared to those fed with Acetes shrimp (7.41 ± 0.88) and bloodworm (11.48 ± 1.51). The fry were fed at 6 % of body weight daily at 2, 4, 6 and 8 times/day. The result showed significant (p < 0.05) differences in the weight gain (%) among the treatments where 2 times/day yield the highest value (316.23 ±36.94 %). Over all it could be concluded that 40 pcs/m2 was the most suitable stocking density under a monoculture system in the RAS in term of production.
