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 was done using probiotics. The experimental three group’s basal diets with probiotics diets include Bacillus subtilis + Lactobacillus rhamnosus diet-E3, basal with Antibiotics diet-E2 and only basal diet in the control -E1. Feeding trail experiments were conducted for 60 days and growth parameters were monitored through Weight gain, Specific growth rates, Percent survival, Biochemical analysis, Microbial analysis and Antibacterial activity of probiotics were significantly (P<0.05) higher in probiotics diets (Calcium)- E3 incorporated diet fed fish followed by other experimental groups when compared with control deits-E1. The FCR values also recorded to be better with diet-E2 compared to Control diet- E1, demonstrates the efficient utilization of feed by fishes. The present study conclude that probiotics with starch was the best feed concentration food for the freshwater fish L. rohita.
