Abstract
The nutritional evaluation, survival rate and growth of fresh fish water Labeo rohita fingerlings fed with artificial feeds along with supplements like Calcium, Starch and Sardine oil were done using probiotics. Three experiments were ere directed for 30 days each to assess the possible advantages of threemulti-strain probiotics in three distinct phases of adolescent Rohu (hatchling—8 daysold, fry—38 days old and progressed fry—68 days old) on the endurance and development. In this study, four different types of treatments were used; namely, T1: Control, feed without any dietary supplements, T2: feed with Lactobacilli, Bifid bacterium, yeast, Spirulina and phytase, T3: feed with Lactobacillus, yeast, seaweed and amylase, and T4: feed with Lactobacilli, Bacillus and yeast only. Hatchlings fed with T2 feed showed highest survival (72.62 ± 7.27c), which is about 25% improvement in comparison to the survival of the Control group (46.87 ± 5.27a). Similarly, T3 (59.02 ± 8.23b) and T4 (60.42 ± 5.67b) showed at least 10% increment in survival as compared to that of Control (T1). The hatchlings in T2 group had significantly higher (p b 0.05) final weight (0.57 ± 0.05b) compared with T1, T3, and T4which had final weights of (0.51 ± 0.07a), (0.42 ± 0.10ab) and (0.39 ± 0.02ab) respectively. Specific growth rates of T2 and T3were found significantly higher (p b 0.05) in hatchlings. In fry stage, the feed with all the probiotic blends showed fundamentally higher explicit development than the Control.
