  • A long-term (160 days) feeding experiment was conducted to evaluate effects of dietary soybean meal (SBM) on growth of rainbow trout (Oncorhynchus mykiss). Fish fed diets containing up to $46\%$ of SBM showed the same growth rates with control during the first 60 days (p>0.05). However, growth showed a gradual decrease with the culture period. At the end of 160-days experiment, fish fed diets with above $34\%$ of SBM showed a decrease in growth rate compared to the control group. Fatness of experimental fish was reduced with an increase in dietary SBM levels and in feeding period. Hepatosomatic index was significantly lower from fish fed the diets containing above $46\%$ of SBM than that from fish fed the control diet throughout the 160 days of experimental period, and fish fed diet containing above $46\%$ of SBM appeared to make restricted utilization of carbohydrate sources. These results may suggest that soybean meal could be used up to $22\%$ in trout diet as a substitute for fish meal without unfavourable side effects.
