Fish were reared for 30 days in sized nets 100x100x50 cm³. The experimental obeserved were different levels astaxanthin supplementation, namely; 0, 100 and 200 mg/kg diet. The result showed that, fed on the diet supplemented with astaxanthin 200 mg/kg diet produced the best final weight, daily growth rate and feed efficiency (8.24 g, 4.14% and 85.31%). The supplementation astaxanthin 100 and 200 mg/kg diet did not affect on survival rate of snakehead
