Abstract
The study evaluated the effect of different background colors of artificial incubator on the hatching rate of Nile tilapia eggs. The study had five treatments with three replicates namely: Treatment 1 -Transparent (Control), Treatment II- Blue, Treatment III - Green, Treatment IV - Black, Treatment V - Red Average weight and survival of fry were likewise determined after a week of stocking in hapa. The results of the study showed that Nile tilapia (Oreochromis niloticus) eggs in Treatment IV had the highest hatching rate during artificial incubation while Treatment III and Treatment V had the highest survival rate and average weight of fry, respectively, in hapa after one week. However, analysis of variance revealed that hatching rate, average weight and survival of fry were comparable.
