Abstract: Production potential of Monopterus cuchia in semi-intensive monoculture system was studied at a stocking density of 51 fingerlings m-2, 42 fingerlings m-2 and 33 fingerlings m-2 fingerlings, in the treatment T T and T for a period of 240 days at Bharhatta, 1, 2 3 Netrokona; sadar, Gopalgonj and Jinaigati, Sherpur, Bangladesh to find out a new culture technology on a sustainable aquaculture method of cuchia fish. About eight small ditches with an area of 33.45 m-2 were selected for the experiment accommodating two replications for each treatment. At stocking, all fingerlings were of same age with a mean weight of M. cuchia 99.20±10.98g production in treatment T T and T were 352.0±6.66, 377.0±5.24 and 376.0±3.82 kg.ditch-1 respectively after 240days. Food 1, 2 3 conversion ratio was significantly lower in T (2.16±0.06) than T and T . Relative growth (RG) was significantly higher in 1 2 3 treatment T (2.56±1.02) than treatment T and T The mean differences of gross yield among different treatments were significant 3 2 1. (P<0.05). The net monitory profit of treatment T T and T were -3670, 18566 and 34890 Tk.ditch-1.after 240 day, respectively. 1, 2 3 The mean differences of net monitory profit among different treatments were also significant (P<0.05). Despite the yield values, it is advocated that M. cuchia culture is a sustainable aquaculture technology to meet up the protein deficiency, earn foreign currency and socio-economic status of the general people of Bangladesh and extremely helpful towards the protection of M. cuchia from extinction as well as for its conservation.
