Abstract/ Executive Summary:

The present study was conducted to know the fish biodiversity in Kafrikhal beel under Mithapukur Upazila, Rangpur, Bangladesh. It was undertaken during the period of January to March 2011. A questionnaire had used to collect the key informations from 50 randomly selected fishermen from the study areas. The present study had revealed the presence of 54 species of fish from the Kafrikhal beel including 10 endangered and 7 critically endangered. Among the recorded 54 species; 15 species were abundant (27.78%), 13 species common (24.04%), 19 species less common (35.19%) and 7 species were rare (12.96%) respectively. Catfishes (24.07%) were the most dominant group followed by Carps (16.67%), Barbs (9.26%), Perches (12.96%), Snakeheads (87.40%), Eels (5.55%), Minnows (3.70%), Clupeids (3.70%) and Miscellaneous (16.67%) respectively. It will be very helpful to identify areas of high fish biodiversity and to mitigate the loss of fish biodiversity in the Kafrikhal beel.

Keywords: Fish biodiversity, Kafrikhal beel, Mitigation of biodiversity loss

Location: Kafrikhal beel under Mithapukur Upazila, Rangpur, Bangladesh

Start Date: 00-01-2011

End Date: 00-03-2011

Program Area: Conservation and Biodiversity

Commodity: Fish

Objectives:

Runoff from agricultural and urban areas, the invasion of exotic species, and the creation of dams and water diversion have been identified as the greatest challenges to freshwater environments. This beel plays a very important role in the alleviation of rural poverty and supplying food to the poor fishing community. Fisheries managers and policy makers must, therefore, take a precautionary approach in their management of fish diversity.

Methodology:

The study was carried out in Kafrikhal beel under Mithapukur Upazila in Rangpur district during period of January to March 2011. In the study, a total of 50 fishermen (both professional and subsistence) were randomly selected from three villages (Jalalpur-20, Edgharpur-15 and Horiharpur-15) surrounding the beel. At first, primary information was collected from Senior Upazila Fisheries Officer, Mithapukur regarding the fish biodiversity and fish availability in Kafrikhal beel. During collection of data, both primary and secondary sources were considered. For the study a combination of interview schedule, participatory rural appraisal (PRA) tool such as, focus group discussion (FGD), social mapping and cross interviews with key informants were used for fishermen. The collected data were summarized and processed for analysis by using MS Excel and SPSS-20 version. Tables, graph, piechart etc. had been used for data presentation.

Achievement/Findings:

Nowadays the fish biodiversity of the Kafrikhal beel is under great threat due to fishing pressure, overfishing, pollution, siltation, urbanization and human intervention. These have been created a great impact on beel ecology. As a result, the water quality is deteriorating day by day and the availability of fish species and another aquatic biodiversity is decreasing gradually. The complete drying up in many parts of this beel is a common scenario during lean season, which is detrimental to fish populations and ecosystem. The findings of the study will be applicable to the management of this beel. Our govt. should take proper steps to save fish biodiversity in this beel. People in adjacent areas should awareness. Moreover, the findings will to be useful to students, researchers and policy makers.
