Fish meal is generally expended as the foremost protein supply in the fish diet. The risingcost of this component inflicted the aquaculture industry to seek a substitute in lesseningthe pellet cost. Thus, fish waste was tested in this study to investigate its viability. Anexperiment was performed to study the effects of fish waste and carcass on the growthperformance of Nile tilapia fry. Solid fish waste of three different common speciesavailable in Mukah’s wet market was formulated into an artificial diet. The diet wasformulated into three treatments consist of three protein levels (40%, 45% and 50%) with4000 kcal/kg energy. A controlled group was fed with a commercial pellet consisting of45% protein level. Fish were fed at 4% of body weight twice daily for 45 days. Fry rearedin a controlled group was discovered highest weight gain, specific growth rate and lengthgain. There was no significant difference in all treatments for all parameters measured.The lowest weight gain and specific growth rate were recorded in fish fed 45% proteinlevel (T2) group. Fish in T3 (50%) achieved the highest survival rate while T1 (40%)group recorded the lowest. The best and lowest Feed Conversion ratio (FCR) wasrecorded in the control group. In conclusion, the performance of formulated feed usingfish waste is similar to commercial pellet as no significant difference can be observed inall parameters measured.
