Abstract/ Executive Summary:

The greater Rajshahi District has vast fisheries resources, covering 2,39,292 ha, nearly one-third of the total land mass. There are 18,991 ha of rivers and canals, 19,889 ha of beels and 1,85,043 ha of floodplains. It has also 56,954 ponds covering an area of 15,369 ha. The total fish production of the area was estimated as 59864 metric tones (mt), of which open water contributed 24,562 mt (41.03%) and culture fishery produced 35,302 mt (58.97%) for the year 2000. The fish production from rivers and canals, beels, floodplains, and ponds were estimated as 2,316, 6,518, 15,728 and 35,302 mt, receptivel. The data shows that ponds contributed the highest fish production (2,297 kg/ha), followed by beels (328 kg/ha), river and canals (122 kg/ha), and floodplain (85 kg/ha). The average fish production was calculated as 110 and 2297 kg/ha for capture and culture fishery, respectively. The relative share of fish production for different water bodies were calculated as 3.87, 10.89, 26.27 and 58.97% for rivers and canals, beels, floodplains, and ponds respectively. The growth rate of fish production from 1990 to 2000 for these areas were calculated as -0.96, -1.91, -2.06 and 5.68%, respectively. From 1990 to 2000, capture fishery declined nearly 5,855 mt (1.92%) per year, whereas culture fishery increased 5.68%, and combined total fish production increased by 1.31%.

Program Area: Resource Development and Management

Commodity: Fish

Objectives:

To study the fisheries resources management of the greater Rajshahi District.

Methodology:

The information needed for this study was collected from multiple sources. Firstly, an extensive literature reviews were made in the area of fisheries resources. Secondly, the primary data for the study were collected through survey method from the fishermen, fish traders, Government and NGO personnel and experienced persons related to fisheries research and education (N=250). The information thus collected was analyzed to bring it to bear on the hypothesis by simple tabulation and statistical calculations. The fish species were collected from the different fish markets, landing certres and on the fishing spots of the study area for the taxonomic study. Supporting papers, documents, information and records were collected from the Water Development Board, Rajshahi, Bangladesh. Contracts were also made with different Fisheries Co-operative Societies and other experienced personnel to obtain data on the fisheries resources of the greater Rajshahi District.

Achievement/Findings:

It is therefore necessary to understand and recognize the need for aquatic habitats and the adaptation of different fish and prawn populations to certain sets of hydrological conditions for breeding, feeding, migration and movement. The negative impacts of flood control and road infrastructure on floodplain fisheries are being mitigated through a programme of floodplain stocking and fish pass construction. While planning water resources development projects, comprehensive studies on different aspects of ecological needs of fisheries species should be undertaken so that a meaningful understanding of the needs for fish and other aquatic animals emerges.
