Jesi 2021. The effectiveness of adding vitamin-B complex into feed on survival and growth rates of snakehead fish (Channa striata Bloch). (Supervised by Isriansyah and Sumoharjo). This study aimed to analyze survival and growth rates, feed efficiency and feed conversion ratio of snakehead fish with the addition of vitamin-B complex into the fish feed. This study used a completely randomized design (CRD) with five treatments and three replications, namely: P1 = control, P2 = 2 grams of vitamin-B complex/kg of fish feed, P3 = 4 grams of vitamin-B complex/kg of fish feed, P4 = 6 grams of vitamin-B complex / kg fish feed and P5 = 8 grams of vitamin-B complex / kg fish feed. The results showed that theaddition of vitamin B Complex with different doses in the feed did not have a significant effect on the survival rate, absolute weight growth, specific growth, daily growth rate, absolute length growth, feed efficiency and feed conversion
0,05. The survival rate of snakehead fish fry was at P4 and the lowest was at P1. The absolute length growth rate at P5 and lowest at P1. The absolute weight growth rate highest at P5 and lowest at P1. The daily growth rate is at P5 and the lowest is at P1. The specific growth rate was at P4 and the lowest was at P1 treatment. The feed efficiency is at P5 and the lowest is at P2. The feed conversion was at P2 and the lowest was at P5..
