    Abstract


    Four isoenergic feed pellets of different protein and lipid levels, namely D1 (35% Pr, 10% L), D2 (42% Pr, 10% L), D3 (42% Pr, 5% L) and D4 (35% Pr, 5% L), were used to investigate the growth of bagrid catfish Mystus nemurus in cages breed in water reservoir in Yen Thanh, Nghe An. Experimental fish of initial size of 47.0 ± 1.2 g were fed twice a day to satiation in 85 days. Fish fed on diet D2 which contained the highest protein and lipid levels showed the best growth rate and the lowest feed conversion ratio (P <0.05). Fish fed on D4 diet with the lowest in protein and lipid content yielded the lowest growth rate and protein efficiency ratio and the highest feed conversion ratio (P <0.05). Fish fed on diet D3 gave similar growth rate, protein efficiency ratio to those fed on diet D1 but had a lower feed conversion ratio (P <0.05). Survival rates of fish from all feed treatments were high (93.0-96.0%) and no significant difference was found among treatments. Based on these results, diet D2 (42 % protein and 10 % lipid) was recomended for maximizing growth rate and feed utilization of Mystus nemurus.
