To investigate the technical and co-management aspects of mud eel (Monopterus cuchia) culture by ethnic (Adivasi) communities in the Northern Bangladesh

摘要: The current study was undertaken to observe production potential of mud eel in participatory semi-intensive culture systems Noukuchi rice field (treatment T J), Sherpur and Gohalidew Ponds Ti), Netrokona with an area 0.20 0.06 ha, respectively. water bodies were stocked cuchia fingerlings (95.96±3.21 95.45±4.02 g) at a density 5187.ha- 1 12866.ha- , respectively treatment T1 T2 for period 150 days. Rice pond habitat improved by installing mud-compost hips, bamboo roots; plastic bamboo-made hollow pipes, aquatic vegetations. The.fish fed 3% bw (1% dead.fish, 1% dry.fish, 1%jlesh snails bivalve) every alternative day. In addition live carp fry also added the system 15 days interval. fish system, individual final weight 310. 63±17.59 g period. average daily gain, specific growth rate, FCR survival rate 1.43±0.08, 0.79±0.23, 1.0±0.0 90.0±0.0, Comparatively, lower peiformance M observed (I'i). mean differences gross yield between two treatments significant (P<0.05). results this indicated that showed significantly higher (cuchia 1440.0±0.0, native 1122.48±9.32 kg.ha- .I 50 days- ) than T2• physico-chemical factors found be suitable culture. semi-interiSive ponds is good proposition as aquaculture technology save from declined enhance nutritional status socio-economic improvement Adivasi people.
