Abstract
The study evaluate the growth, survival and skin coloration of red tilapia (Oreochromis niloticus L.) fry fed with diet containing carotenoid pigment from jute leaves (Corchorus olitorius). The treatments evaluated were: Treatment I - control diet (0% carotenoid extract); Treatment II - diet with 500 mg carotenoid extract from jute leaves; Treatment III - diet with 1000 mg carotenoid extract from jute leaves. Results of the study showed that red tilapia fed with diet containing 1000 mg pigment extract from jute leaves had the highest final weight, gain in weight, and absolute growth rate. However analysis of variance revealed no significant differences among the treatments. Fish survival and skin coloration were likewise comparable.
