Evaluation of production performances of Koi (A. testudineus), with Shing (H. fossilis) and GIFT Tilapia (O. niloticus) in semi-intensive culture management

AHM Kohinoor, Md. Moshiur Rahman and Md. Shahidul Islam

Production potential of Koi (Anabas testudineus) with Shing (Heteropneustes fossilis) and GIFT Tilapia (Oreochromis niloticus), an experiment was carried out for a period of four months from March to June 2013 at Dohakhola village in Gouripur upazila under Mymensingh districts in six farmers’ ponds having an area of 600-800 m2 each. The stocking density of Koi was same in all treatments, but Shing and GIF tilapia density were varied in different treatments. Fingerlings of Koi were stocked at the rate of 125,000/ha in all three treatments. Shing were stocked 37500, 32500 and 27500/ha in treatments-I, II and III, respectively. In addition, monosex GIF Tilapia was also stocked 5000, 10000 and 15000 in treatments-I, II and III, respectively. In all the treatments, the fish were fed with pelleted feed (30% crude protein) at the rate of 5-20% of estimated body weight. All ponds were completely harvested after four months of rearing, first by seine netting followed by draining out of the ponds. Koi reached at an average final weight of 140.10 ±5.60, 132.66±5.11 and 129.73± 4.07g in treatments-I, II and III, respectively. The final weights of Shing were 32.47 ± 7.11g in treatment-I, 35.40±6.59 and 37.51± 6.95g in treatment-II and III. Relatively, identical growth of monosex GIFT tilapia in terms of weight was attained in all the treatments. It grew to an average weight of 210±9.75, 208±7.51 and 206±6.21g in treatments-I, II, and III, respectively. The survival rates of various species in three treatments were fairly high. The survival rate of Koi, Shing and monosex GIF tilapia were ranged from 82-88, 72-79 and 87-94%, respectively. The gross production of fish in three treatments was calculated from the growth and survival of each fish species. The highest gross production of 17995 kg/ha were obtained in treatment-I and the lowest of 16805 kg/ha in treatment-II.
