Abstract/ Executive Summary:

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.

Objectives:

Objective of the study was to find out the fishing technique using sutijal (purse net) in the Chalan Beel, in different parts of studied wetland.

Methodology:

Study area and duration: The present study was carried out study in Chalan Beel- the largest wetland of Bangladesh situated in the northwest region. This research was conducted between July 2011 and June 2014. Sampling framework: Extensive field surveys were made for the collection of primary data. Information regarding the gear structure, fishing technique, mode of operation and catch composition were collected through personal interview and detailed discussion with local fishermen as well as direct observation. Interviews were carried out using a prepared questionnaire which was pre-tested in field situation and updated before final use. Amount of catch was measured in kilogram (kg) and weight was determined using a pan balance. Species in the catch were identified following published literatures (Rahman 1989, 2005; Talwar and Jhingran 1991). Benefit cost ratio (BCR) of net was calculated using the following formula: BCR=B/K (FAO 1991); where B is the net benefit and K is the sum of cost. Standard market price of fishes was considered during this calculation. Data analysis: Collected data were accumulated, grouped and interpreted according to the objective. Data were subjected to simple descriptive analysis using computer software Microsoft Excel 2007.

Achievement/Findings:

Sutijal is very harmful to all kinds of fish and other aquatic macro organisms and brood fish, fry and fingerlings are declining day by day in the study area because of this fishing net. Thus, for the proper management of rapidly dealing fisheries resources, there should be strict ban on the area of destructive fishing method and only scientific methods for sustainable fishing should be allowed.
