Abstract/ Executive Summary:

A research work was conducted to observe the beel management of the Dhaka beel situated in Tangail district, Bangladesh. Data were collected through questionnaire survey, discussion and interviewing. Dhaka beel is a 13ha semi-enclosed beel brought under the nursery management project in 2010. The beel was stocked with approximately 100000 fish larvae of 4 days old during May to June. After 60 days of proper management the stocked larvae were sampled and 70,000 of fry were obtained. In the studied beel the annual production was 2.4 mt in 2009 where beel nursery management has increased the production to 7.10 mt in 2010 which also included several non-stocked indigenous fish species. Socio-economic conditions of people were also improved where 80% of the people believed that it was true. Beel management has played an important role to minimize the rapid reduction of many important indigenous species through four to five months of management where fishes got the chance of recruitment. Management, guarding, harvesting, and income were equally shared among the group members. Findings of the present study suggest that beel nursery management can be an excellent scope for improvement of fish production and socio-economic status of the adjacent people.

Keywords: Beel, Nursery management, Recruitment, Socio-economic

Location: Madhupur upazila located in the Tangail district Bangladesh.

Start Date: 00-02-2011

End Date: 00-09-2011

Program Area: Socio-economic and Policy

Commodity: Fish

Objectives:

The specific objectives were: 1) to evaluate the potential importance of the beel management; 2) to determine fish species composition and their yield; 3) to compile the information about the household communities around the beel areas and 4) to evaluate farmer’s dependency level on the beel fisheries.

Methodology:

Study area: The survey was undertaken in the Dhaka beel (13ha) which is one of the most important beels in Madhupur upazila located in the Tangail district Bangladesh. The survey was conducted from February to September, 2011. Research approach and technique: The quantitative data were collected by reconnaissance survey while qualitative information was explored by case studies as the primary tools of data collection [4] . Method of data collection: Primary source: Primary information was provided directly by the fishermen through direct observation, interviews and discussions. To obtain primary data, the study employed some techniques such as key informant’s interview, participatory rural appraisal (PRA) with focus group discussions (FGD), observations, and documents screening time to time. Secondary sources: Secondary data was collected through literature and publications available from Upazila Fisheries Office, quarterly and annual reports. Books of Bangladesh Bureau of Statistics were used to cross- check, complement or illustrate the primary data obtained through the survey and group discussion. Editing and tabulation of the data: After collection, the data were edited for analysis. In order to minimize error, data were collected in local units and later, local units were converted into standard units. After completing the data collection, processed data were transferred to a master sheet and completed with a view to facilitate tabulation. Considering the objectives a list of tables were prepared. For completing the study a distinct list of steps was followed. Processing and analysis of data: All the collected data were processed and analyzed by statistical analyzing software Microsoft-excel and SPSS version 15.0.

Achievement/Findings:

The sustainability of beel fisheries resources are especially important both from ecological and economic point of view. Due to the proper beel nursery management the annual production had increased from 2.4 mt to 7.10 mt in the studied Dhaka beel. Different fish species were disappearing from the beel where beel management practice has created the opportunity of their recruitment. The findings suggested that beel nursery project is economically profitable than the fish fry releasing program. It is clear that community based beel nursery management in the water areas may be an excellent example to stimulate income generation, employment opportunity and to supply nutrition for ensuring sustainable livelihood security
