title: Effect of niacin and folic acid in feed rations on growth and live weights of Green catfish (Mystus nemurus Valenciennes 1840).
abstract: This study aims to justify effects of niacin and folic acid in feed rations on growth and survival rate of the fish under in vitro conditions. A Completely Randomized Design (CRD) with four replications for Experiment I and three replications for Experiment II was used. Niacin (0, 5, 10, 20 and 40 mg kg(-1)) and folic acid (0, 2, 4, 6 and 8 mg kg(-1)) were used for Experiments I, and II, respectively. The cement tanks were used for Experiment I and fibre tanks for Experiment II. A static water system was used. Water temperature was maintained at a range from 26 to 30 degrees C with pH values from 7.4 to 7.9. The results showed that niacin at a rate of 10 mg kg(-1) feed ration gave significant differences on weight gained %, survival %, protein efficiency ratio, specific growth rate % and feed conversion ratio with mean values of 99.92, 100, 1.18, 5.77 and 1.35, respectively. Folic acid at a rate of 2 mg kg(-1) gave significant differences on weight gained %, survival %, protein efficiency ratio, specific growth rate % and feed conversion ratio with mean values of 108.88, 100, 1.22, 6.13 and 1.43, respectively. Niacin at a rate of 10 and 2 mg kg(-1) of folic acid were the best rates for in vitro culture of Green catfish.
