The present study on fishing technique using sutijal (purse net) in the Chalan Beel was conducted for a period of 3 years from July 2011 to June 2014. Net description, operation details and catch composition were studied through field survey in different parts of studied wetland. Three different categories of sutijal were recorded. Catch composition revealed that all types of aquatic organisms are being caught by this net. Benefit-cost ratio of studied fishing net was also calculated. Frequent fishing by this net, especially in streams of remote areas of the Chalan Beel resulting in decline of fish species and abundance. Appropriate management steps are recommended to get rid of this destructive fishing gear.

“…The number of recorded fish species from Kumari Beel was similar to various beels (MACH 2006;Mustafa et al 2014) and slightly lower than the Chalan Beel (Galib et al 2009a), Dahia Beel (Flowra et al 2009), Halti Beel (Imteazzaman and Galib 2013), Brahmaputra River (Galib 2015) and Mahananda River (Galib et al 2016). Most of the respondent (82%) mentioned that the fish species was decreasing day by day before establishing the fish sanctuary.…”

CitationJoadder MAR, Alam B, Siddique AB and Naim J (2016) Present status of fish diversity in the Beel Kumari in relation to fish sanctuary and fishing gears. Journal of Fisheries 4(2): 390-396. DOI: 10.17017/jfish.v4i2.2016.172 AbstractThe study was conducted on Beel Kumari beel (wetland) in Rajshahi, Bangladesh from October 2013 to September 2014. A total of 52 species of fish were recorded and the dominant species was Mystus tengara (Tanagra (9.75%). Exotic species like bighead carp (Aristichthys nobilis), silver carp (Hypophthalmichthys molitrix) and common carp (Cyprinus carpio) were also commonly found. Of the indigenous species, Ompok bimaculatus, Puntius sarana, Pseudeutropius atherinoides, Botia dario, Mystus aor and Chitala chitala were abundant, though these species were rare before the establishment of the fish sanctuary. Four groups of fishing gears i.e. net, trap, spear and harpoons and line fishing were found to use, among them 8 types of net, 7 types of trap, 4 types of spear and harpoon and 4 types of line fishing were recorded. Among these gill net contributed to the highest catch (32%) and push net was the lowest (6%). Most of the respondents (80%) were found to believe that their fish catch had increased considerably due to impact of fish sanctuary establishment and effective community based fisheries management approach employed in this beel.

“…Critically Endangered, Endangered and Vulnerable. Decreasing trend of freshwater fishes in various rivers of Bangladesh has already been reported by several researchers (Galib 2015;Joadder et al 2015;Chaki et al 2014;Mohsin et al 2014Mohsin et al , 2013Galib et al 2013). In a recent research Hossain (2014a) declared that 30 riverine fish species have became extinct though the researcher did not mention the methodology followed for his findings.…”

This study was carried out in the Mahananda River from January to December 2013 with a view to determining the seasonal variation and community structure of fishes along with some conservation issues. Monthly sampling was carried out using traditional fishing gears and fishes were identified based on morphometric and meristic characters. A total of 4082 individuals of native fish species were captured, analyzed and classified into 62 species belonging to 46 genera, 25 families and 9 orders. Cypriniformes and Siluriformes were the dominant fish orders represented by 19 species each and the most abundant family was Cyprinidae (14 species). In addition to indigenous individuals, 9 individuals of 2 exotic fish species (Hypophthalmichthys molitrix and Pangasius hypophthalmus) were also recorded. Among three sampling sites, S-1 was the most diversified in terms of not only the number of individual fish but also the number of species present represented by mean (±SE) individuals of 151.50±25.22 and species of 25.58±3.91. Three distinct fish groups of fish families were revealed from the cluster analysis of similarity. To improve the situation, control of illegal fishing gears, establishment of sanctuaries and legal protection for threatened species are recommended.
