River water finds multiple uses like agriculture, industry, transportation, aquaculture, and public water supply. Natural waters are being contaminated as the quality of water is being affected by anthropogenic activities, in developing countries like Bangladesh. From the point of view, the physicochemical parameters (water temperature, pH, electrical conductivity, total dissolved solids, DO, BOD, alkalinity, total hardness, nitrate) of seventeen rivers in Bangladesh were reviewed from January 2021 to June 2021. The water quality parameters of some rivers were found to be far above the suitable limits, which is dangerous for human health, agriculture, and fisheries. It is therefore necessary to check the water quality at regular interval of time to conserve the natural ecosystem of the rivers of Bangladesh. Furthermore, this study would help to create and...

The aim of the present study was to identify the traditional fishing gears and crafts used by the fishermen of Payra River at Amtali upazila under Barguna district for a period of 12 months from September 2015 to October 2016. Questionnaire Interview (QI) and Key Informant Interview (KII) were done to obtain information about fishing gear and craft. The investigation showed that a wide variety of fishing gears and crafts were operated throughout the year in the study area for commercial fishing. Fishermen were found to follow 4 fishing techniques i.e. netting, angling, trapping and spearing. Among them 18 types of the fishing gear was recorded to be used by the fishermen of which 5 gill, 1 seine, 2 fixed purse, 1 lift, 1 cast, 2 push/drag nets, 2 traps, 2 hooks and lines and 2 wounding gear...

Primary data were collected through questionnaire interviews of 80 fishermen, 8 focus group discussions, and 5 key informant interviews. A total of 64 fish and prawn species under 22 families and 11 orders were recorded. Cyprinidae (31.25%) was the most diversified family. On the basis of their availability the recorded species were categorized into four groups: available (35.94%), less available (29.69%), rare (20.31%), and very rare (14.06%). A total of 10 fishing gears under 5 major categories viz., fish nets, fish traps, wounding gears, hooks and lines, and fish aggregating device were recorded. Overfishing, siltation, use of banned fishing gears, irrespective catching of juvenile and brood fishes, katha fishing, etc. were detected as major threats to the fish diversity and habitat degradation of the fishes in this river. Therefore, dredging, use of legally applicable fishing gears, establishment and management of fish sanctuary, community based fisheries management, stocking of economically and nutritionally important indigenous fish species, implementation of fish acts and laws, and increasing fishers' awareness should be undertaken to conserve the fish diversity in this river.

The highest percentage (46.25%) of the fishermen belonged to middle age group, and 68.75% were Muslim. Among the respondents 61.25% had nuclear family, 17.50% had no education, 72.50% had access to drinking water from tube-wells and 71.25% lived in earthen houses. Around 93.75% fishermen had homestead land, 56.25% borrowed money from non-government organizations, 75.00% fishermen got Vulnerable Group Feeding (VGF) card from the government. The result of this study shows poor livelihood status of the fishermen with a number of constraints for fishing. To improve the fisheries resources and livelihood status of the fishermen credit facilities and alternative livelihood opportunities should be ensured.

Data were collected by Questionnaire Interview (QI), Focus Group Discussion (FGD) and cross-check Interview of fishermen and resource persons from 8 villages by the river Banar under 4 Unions of Fulbaria Upazila, under Mymensingh District. A total of 62 species of fish and shellfish under 10 Orders and 24 Families were recorded from the Banar river. Among the Orders recorded from the studied river, Cypriniformes (30.65%) was the most dominant Order followed by Siluriformes (29.04%), Perciformes (22.58%), Synbranchiformes (6.45%), and Decapoda (3.23%). Cyprinidae was the most dominant family contributing 17 species. The availability status of identified species were common (40.32%), seasonal (20.97%), rare (17.74%) and very rare (20.97%). Seventeen threatened fish species were recorded from the river in which 8 species were endangered, 7 were vulnerable and 2 were critically endangered. Among the threatened fish species, endangered (47.06%) was found to be most abundant followed by vulnerable (41.18%) and critically endangered (11.76%). Fishermen were found to use 10 types of the fishing gears. Use of illegal fishing gears, overfishing, decreasing depth of river and katha fishing were observed as major threats for fish diversity in the river.
