The present study highlighted a case study on sustainable management of Halti Beel tank sanctuary, Bangladesh (a part of Chalan Beel) established for the betterment of fsheries and fshermen community. The study was conducted for a period of 6 months from July to December 2017. Both primary and secondary data was used for a comparison before and after effects of Halti Beel tank sanctuary considering three parameters viz., fsheries diversity, production trends and socio-economic condition of fshermen community. During the study period, diversity in both native and exotic fsh species (71) were increased where 62 species were native and 9 were exotic under 26 families of 11 orders. This number (71) was observed 97.22% higher than the number of species before declaring Halti Beel tank as fsh sanctuary. Recovery rate was observed highest for the order Siluriformes (11) and the lowest for Channiformes (1). Cypriniformes was the most diversifed order with 24 species (18 native and 6 exotic species). The observed data showed a dramatic increase in fsh production from 8.77 to 37.50 metric ton within four fscal years whereas the gradual production trend was recorded 10.12, 29.47, 35.10 and 37.50 metric ton, respectively in the year 2013-2014, 2014- 2015, 2014-2015 and 2016-2017. The study was also showed a satisfactory improvement in fnancial and housing assets as socio-economic status of fshermen community involved in the management of Halti Beel tank sanctuary. ©2020 Agriculture and Environmental Science Academy Keywords Chalan Beel Fish diversity Fish retrieval Halti Beel Sanctuary GRAPHICAL ABSTRACT Citation of this article: Siddique, M.A.B., Hussain, M.A., Alam, M.M., Haque, M.A. and Flowra, F.A.
