Feed evaluation study on several type of commercial feed for catfish culture

Abstract

This study was conducted at marine hatchery, Department of Fisheries Science and Aquaculture, University Malaysia Terengganu (UMT). Three type of catfish pellet with differences crude protein were used in order to evaluate the suitability of them for Clarias gariepinus culture. Three fishes were taken out for protein analysis while the total length and total weight of 30 fishes were taken out and recorded in the early and by the end of the experiment. The mortality rate and amount of given feed was calculated and 3 fishes from each tanks were taken out for proximate analysis. The performance parameters (Absolute growth rate (AGR), food conversion ratio (FCR), Protein Efficiency Ratio (PER), Protein Digestibility and Survival rate) of three catfish pellet (Terengganu pellet, TP pellet and Cargill pellet) was determined through the proper calculation. Cargill pellet has the lowest value of AGR (0.41±0.15), FCR (0.94±0.37), PER (0.49±0.16), Protein digestibility (85.00±1.3) and Survival rate (93.30±3.51) compare to the TP pellet and Terengganu pellet. This result shows that the Cargill pellet was the best feed for the African catfish.
