Abstract:
The aim of this study was to evaluate the effects of substituting fishmeal (FM) with soybean
meal (SM) on new muscle generation of silver barb, Barbonymusgonionotus. Five diets were
prepared with SM 0 (FM 100), SM 25 (FM 75), SM 50 (FM50), SM 75 (FM25) and SM 100%
(FM 0%) by replacing FM with SM. Each diet was fed to B. gonionotus having initial weight of
8.80 ± 3.11 g to apparent satiation twice a day for six months. During the 120th days, the growth
were significantly (P< 0.05) higher in fish fed with SM50 diets compared to SM0 diets. But in
150th days, growth were significantly (P<0.01) higher in fish fed with SM25 diets compared to
SM0 diets. Finally during 180th days, growth were significantly (P<0.1) higher in fish fed with
SM50 and SM25 diets compared to SM100 diets. There was a significantly(P< 0.05) increased
number of muscle fiber atSM50, SM25 and SM0 diets compared to SM100. Diameter of muscle
fiber (µm) was significantly(P<0.01) increasedat SM50, SM25 and SM0 diets compared to
SM100 diet. The results of the present study indicated that substitution of upto50% SM with FM
enhanced the muscle growth by promoting hyperplasia and hypertrophy inB. gonionotu |
