In this study, a total of 720 rainbow trout (Oncorhyncus mykiss) having 50.08±0.19 g of average initial weight were
used to compare of usage of the soybean meal, sunflower meal, canola meal and cottonseed meal as the best plant protein
source. Four different feeds which contain soybean meal (SBM), canola meal (CM), sunflower meal (SFM) and cotton seed
meal were used, respectively. Four trial groups were tested in triplicate during 12 weeks. Experimental diets were prepared as
isonitrogenous (42% CP) and isocaloric (13.9 MJ DE/kg feed). At the end of the study, it was observed that there was no
significantly difference among the groups for average feed consumption, condition factor and survival rate, however, average
live weight, live weight gain, feed conversion ratio (FCR), protein efficiency ratio (PER) and specific growth rate (SGR) were
found statistically significant (P<0.05). Moreover, the difference in the composition of carcass and total body between the
groups were found statistically significant (P<0.05). Consequently, it is concluded that soybean meal, canola meal and
sunflower meal can be used as a part of fish meal, however cottonseed meal can be used as only smolt or older trout feeds if it
is cheap and has good quality.
