In an indoor feeding trial for 16 weeks in plastic tanks on Nile tilapia fish fry, dietary graded levels (0, 1, and 2 %) of camphor tree leaves meal were tested for their effects on the fish performance. It was concluded that dietary inclusion of camphor tree leaves meal (particularly at 2 %) had improved significantly fish performance concerning final fish weight,  weight gains (total and daily), relative growth rate, feed utilization parameters (feed and protein intakes, feed conversion, protein productive value, protein efficiency ratio, energy retention), carcass composition (protein, ether extract, energy). So, it could recommend the addition of 2 % camphor tree leaves meal to Nile tilapia fish diets, but it may need more research on the effect of such feed additive on the organoleptic test of the fish meat.
