Effect of diets on growth, survival and coefficient of blotched sankehead Channa maculata (Lacepède, 1801) of fry to fingerlings stage conducted from April to May 2020. The experiment was designed completely randomly with 3 treatments: Treatment 1: Moina + commercial food; Treatment 2: Moina + Filariae; Treatment 3: Moina + marine shrimp. Each treatment was replicated 3 times. The results of this experiment showed that fry fed by moina - threadworms and moina - shrimp developed better and more uniformly than larvae fed by other foods:survival rate from 91.62 to 91.76%, special growth rate with weight from 18.29 to 18.51%/days and length from 4.68 to 4.85%/days, fish grow evenly Group size W = 0.31-0.45 g predominate> 60% and the fish's ability to withstand shock and death is within acceptable ranges from 1.33 to 12%
