Nile tilapia were reared in chemically fertilized and fed (25% crude protein pellets) green water tanks containing Nile tilapia Juveniles (I.W.=86.3-98.3grams/fish). The experiment included five treatments that lasted 66 days in concrete tanks in still water system. Three treatments had areal inputs of 8, 9 and 10 grams diet (25% crude protein) per square meter of surface water area per day for the whole experiment. The other two treatments had pelleted feed inputs of 8 and 9 grams diet (25% C.P.) UR - http://172.23.153.220/th.pdf ER -
