Abstract

An assessment was carried out to investigate the species abundance by catch per unit effort (CPUE) in Ruhul beel 1, 2 and Bamonjibeel 1, 2 under Chalanbeel in Pabna district of Bangladesh. Data were collected from selected sanctuary sites, focus group discussion, personal and group contract as well as Government and Non-Government organizations with prepared and pretested questionnaire. Total 38 species were observed in sample catch from RB-1 and RB-2 during the whole study period. Each of 38 species was not available during all the months in the sample catch. Some species were found during whole study period and some were not available in every month. The mean highest CPUE was observed in case of Badai jal and Khora jal in both beels in both years whereas, the lowest CPUE was recorded in case of Dhundi and Borshi in both sites in both years. The CPUE was increased in RB for every gear and decreased in BB for every gear other than Dharmo jal. There was a highly significant difference in total catch and CPUE among the sites (P
