Aquaculture is promoted all over the world due to the limitations of capture fisheries production. According
of the State of World Fisheries and Aquaculture, total world fisheries and aquaculture production has reached
to 170.9 million metric ton (mt) collectively including 90 mt from capture fisheries and 80 mt from aquaculture
during 2016. Aquaculture in India has grown over six and half fold in the last two decades in which freshwater
aquaculture contributing over 95% of the total production. Indian fisheries occupy the second position in global fish production and second in aquaculture in the world with an annual growth rate of 4.7%, contributing 1.1% to the total GDP and 4.5% to the agricultural GDP of the country. Aquaculture is a feed based industry where feed source alone constitute 60% of the operational cost due to which feeding of fish with balanced diet is very essential. Fish feed management is one of the most important factors in commercial fish farming because feeding regime mostly decides the cost of production of per kg fish, as fish feed have consequences on both, growth efficiency and feed wastage. Lack of suitable technologies to meet location specific demand of farming community and to enhance their adoption rate, there is a need to undertake technology assessment, dissemination, field demonstration, and farmer’s participatory research and training programs. This study aimed to investigate the effects of feed supplement (mineral mixture) on the growth performance of fish in the form of total yield and the economic returns. The feeding trials were conducted in practicing fish farmer’s earthen pond under composite fish farming system with six species. The study revealed that fish fed with mineral mixture added feed (T1) exhibited significant improvement in daily weight gain, feed conversion ratio, feed conversion efficiency and survival as compared to the recommended (T2) and farmers practice (T3).
