Abstract– The current world population demands rich source of protein in their dietary management day by day. Fish is one of the major aquatic animals that is enriched with digestive protein and cost benefit to buy. The fish culture is a lucrative venture in the current era. As fish is aquatic vertebrate so impact of water quality in relation to physico-chemical parameters play a major role in life of fish. The major physico-chemical parameters of water quality management are like pH, Temperature, DO, Total Hardness, Salinity, Ammonia, Turbidity etc plays major role in fish production. The optimal range of these parameters leads to the maximum production of edible fishes like IMCs. The present work focuses on the optimal ranges of certain major water quality parameters for IMCS (catla, rohu, mrigal) culture in cement tanks (Artificial system) by intensive method to promote the fish farmers and culturists to do more and more fish culture which will be economically healthy for them by improving their financial status. Finding of this study shows that the average ranges of the above parameters are pH=7.35, temperature=31-33oC, DO=5.86 mg/l, Salinity=0.26 ppt, Ammonia=0.02 mg/l, Total Hardness=163.12 mg/l & Transparency=35.125 cm were the best suited for the growth of the IMCs. The SGR of Catla, Rohu & Mrigal was 13.08%, 13.28% & 12.75% respectively in 45 days culture period. The total survival rate in this study is 80%.
Key words: IMCS, Intensive mixed culture, Water quality parameters, Growth performance, Cement tank.
