Abstract:	Animal protein is the most essential part of trout feed Shrimp is a good source of animal protein to improve the quqlity of rainbow trout. However, shrimp is very expen~ive in the local market. An alternate way to reduce the cost of trout feed is to use the shrimp meal as low as possible. Feeding trial was conducted with jour group of diet with 70, 50, 30 and 10% shrimp powder with and without incorporating 10% soybean oil in each diet. Rainbow trout jed upon the diets containing more than 50% shrimp powd_er resulted in highest specific growth rate (2.0% per day}, feed efficiency more than 57% and survival rate more than 98 percent. The 10% soybean oil mixed in diet with 30% shrimp powder produced similar growth results of (;out as contrived in 50% inclusion of shrimp powder. The production cost of trout with 30% shrimp powder added with 10% soybean oil was estimated to be 15% less than the feed prepared with 50% inclusion level of shrimp powder.
