The major objective of this experiment was to assess the effect of alternate plant protein sources as a replacement for fish meal in feed on the proximate composition of muscle, liver and tissue in Oreochromis niloticus. O. niloticus of average size (average Weight 45.00±1.25 g, total length 13.28±1.42 cm) were stocked in 100 L glass aquarium. Fish were fed with three experimental feeds (A, B and C) and reference commercial feed (D) for 16 weeks. Feed A, B and C was prepared from four different plant sources and fish meal (40 % crude protein). Fish were fed at the rate 3 % of body weight daily. It has been observed that tilapia fed with feed B in which 20 % fish meal was replaced compared to feed C with other plant sources of protein, had shown significantly higher total protein in their muscle compared to diet other experimental and commercial feeds. In O. niloticus minimum lipid content was recorded in fish fed with diet B compared to A, C and commercial feed. It has been concluded that 20-40% level of fish meal can be replaced in the diet of fish without having any impact on growth and chemical composition of muscle
