2018

Abstract

A study was directed to assess probiotic-enrich dietary effect on the reproductive performance and larvae growth produced from the brood fish of Ompok pabda for 60 days. A total of 120 pairs of broodfish was used and fed with diets incorporating different levels of probiotic viz. 0 (served as a control), 0.6, 0.8 and 1.0g / kg diet under 4 treatments, i.e. PRO0, PRO1, PRO2 and PRO3 having 3 replications of each. After feeding trials, the brood fish were induced to breed with equal doses of ovaprim i.e. 0.5 and 1.2ml/kg body weight for male and female, respectively and subsequently larvae were produced. The experimental fish were observed for the success in reproductive performance like Gonado Somatic Index (GSI), fecundity, percentage of fertilization, percentage of hatching, percentage of deformed and formed larvae. GSI (10.24±0.94), fertilization rate (76.07±1.67) and percentage of hatching (78.65±4.17) found increased in PRO2 treatment. Likewise, in case of growth rate PRO2 also ...
