Abstract

Effect of dietary betain as a food attractant on Growth, Survival, Body composition and resistance to Stress in Caspian roach (Rutilus rutilus) were investigated for 8 weeks. 240 individuals of Caspian roach by the weight of 6. 23± 0. 23 g and density of 20/tank fed in fiberglass tanks. Four treatments of different levels of betain including 0 (control), 0. 5, 1. 0 and 1. 5 percent added to diet (contained 41. 13% protein and 8. 42% fat). At the end of the study, Growth and feeding factors including final weight, weight gain, feed conversion ratio, specific Growth rate, Survival rate, Body composition and resistance to environmental Stressors including thermal (40 oC), alkalinity (pH=12), acidity (pH=2) and salinity Stress (150 g/lit) were assessed. According to the results, there were no significant differences in Growth, feeding parameters and Survival rate between fish fed control and betain supplementation diets (P>0. 05). No significance difference was observed in lipid and ash carcass (P>0. 05), but the highest of carcass protein was obtained in 1% betain (P<0. 05). The longest surviving time against thermal Stress (P>0. 05) and acidity Stress (P<0. 05) were due to 1% of betain and highest rate in salinity Stress was due to control (P<0. 05) and highest Survival rate after alkalinity Stress was due to 0. 5% Betafin (P<0. 05). Totally considering no significant differences in most parameters betain is not recommended to improve the Growth, surviving and resistance to Stress in roach juveniles.
