Abstract

A 56-day feeding trial was conducted with RAINBOW TROUT to examine effects of partial substitution of plant protein sources with fish meal in diets. Two different sources of plant protein including canola and SOYBEAN MEAL, were substituted by fish meal at four levels of 10, 20, 30 and 40%. Each diet was assigned to triplicate groups of fish in a completely randomized design as a 2×4 factorial arrangement, with a control diet.240 fish were used in this trial.10 fish were randomly assigned to each of 24 pens and were acclimated in these pens to the experimental conditions two weeks before treatments began. Measurements of Final body weight, Body Weight Index (BWI), Feed Conversion ratio (FCR), specefic growth rate (SGR), volountary feed Intake (VFI) and protein efficiency ratio (PER) was determined for total experimental duration and carcss composition (dry matter, protein and energy) was determined on first and 56th day for measuring of nitrogen (NRE) and energy retetion (ERE). This substitution caused no significant differences in all criteria measured with control diet (with the exception of final body weight, VFI, NRE and ERE) (p>0.05). Irrespective of substitution levels, comparison of fish fed by two different sources of plant protein in their diets showed that fish fed diet containing CANOLA MEAL had significantly (p<0.05) higher final body weight, BWI, SGR, VFI, PER, NRE and ERE and lower FCR than the fish receiving SOYBEAN MEAL diets. The results of present experiment showed that 40% CANOLA MEAL because of improvement of GROWTH PERFORMANCE in RAINBOW TROUT is feasible to replace compared with 40% soybeam meal. Partial replacement of CANOLA MEAL result in a higher energy availability to fish and also better performance of fish. These results indicate that CANOLA MEAL can be recommended as a more suitable and fish meal-sparing ingredient compared with SOYBEAN MEAL in diets for RAINBOW TROUT.
