Abstract

Fish nutrition has advanced dramatically in recent years with the development of new, balanced commercial diets that promote optimal fish growth and health. Aquaculture industry development has become a great challenge for future generations, not only for feeding expenses but also from availability of ingredients. The utilization of selected probiotic organisms has emerged as a solution with huge application in the aquaculture feed industry. The probiotic feeds inhibits pathogen proliferations, increase health status of fish, improving food conversion ratio and indices optimal growth of fishes. From the results of the present observations, conducted with fingerlings of Cirrhinusmrigalafingerlings fed on Spirulinafusiformis fortified feed of 5 percentage inclusion showed significant growth 3.69g, the highest enhancement in length 1.67cm was observed in fishes fed with PS5(5%)diet. It is clear that incorporation of Spirulinafusiformis in the feed of Cirrhinusmrigalaconsiderably enhanced the growth in terms of specific growth rate, weight gain, length gain and survival of the fish. Therefore, the locally available algal genera can be used as probiotic feed to achieve better results in Indian major carp farming which may have a high commercial value in long term.
