Abstract: The current study was undertaken to observe production potential of mud eel in participatory semi-intensive culture systems
in Noukuchi rice field (treatment T J), Sherpur and Gohalidew Ponds (treatment T1), Netrokona with an area of 0.20 and 0.06
ha, respectively. The water bodies were stocked with cuchia fingerlings (95.96±3.21 and 95.45±4.02 g) at a density of
5187.ha-1 and 12866.ha-1 , respectively in treatment T1 and T2 for a period of 150 days. Rice field and pond habitat was
improved by installing mud-compost hips, bamboo roots; plastic and bamboo-made hollow pipes, and aquatic vegetations.
The.fish were fed with 3% bw (1% dead.fish, 1% dry.fish, and 1%jlesh of snails and bivalve) at every alternative day. In
addition live carp fry was also added to the system at 15 days interval. In the rice fish system, the individual final weight was
310. 63±17.59 g in 150 days of culture period. The average daily gain, specific growth rate, FCR and survival rate were
1.43±0.08, 0.79±0.23, 1.0±0.0 and 90.0±0.0, respectively. Comparatively, lower growth peiformance of M cuchia was
observed in Gohalidew (T1). The mean differences of gross yield between two treatments was significant (P<0.05). The
results of this study indicated that treatment T1 showed significantly higher growth and lower yield (cuchia 1440.0±0.0, and
native fish 1122.48±9.32 kg.ha-1.I 50 days-1 ) than treatment T2 The physico-chemical factors were found to be suitable for
mud eel culture. M cuchia semi-interiSive culture in rice field and ponds is a good proposition as an aquaculture technology
to save the mud eel from declined and enhance the nutritional status and socio-economic improvement of the Adivasi people.
