Abstract/ Executive Summary:

Present status and future prospects of mackerel and tuna fisheries in Bangladesh were assessed during July 2003-June 2004. The work concentrated on the fishing gears, length of fishes, total landings and market price of the catch and highlighted the prospects of the fishery in Bangladesh. Four commercially important species of mackerels and tuna viz. Scomberomorus guttatus, Scomberomorus commerson, Rastrelliger kanagurta, and Euthynnus affinis were included in the study. About 95% of mackerels and tuna were caught by drift gill nets and the rest were caught by long lines (4%) and marine set-bag-net (1%). Average monthly total landing of mackerels and tunas was about 264 t, of which 147 t landed in Cox's Bazar and 117 t in Chittagong sites. Total catches of the four species in Cox's Bazar and Chittagong sites were found to be 956 and 762 t, respectively. The poor landing was observed during January-February and the peak landing was in November and July. Gross market value of the annual landing of mackerels and tunas (1,718 t) was found to be 1,392 latch taka. Nevertheless, the mackerel and tuna fisheries in Bangladesh are increasingly contributing to the marine fish production of the country and have very good potential for further expansion for both domestic and export market.

Keywords: Mackerel, Tuna, Bay of Bengal

Location: Cox's Bazar and Chittagong district

Start Date: 00-07-2003

End Date: 00-06-2004

Program Area: Animal Health and Management

Commodity: Marine fish

Objectives:

To report about the fishing gears, length of fishes) total landings and market price of the catch and highlighted the prospects of the fishery in Bangladesh.

Methodology:

The two most important coastal fish landing sites) viz Cox's Bazar and Chittagong were selected as the sampling stations. Commercially exploited species of mackerels and tunas viz. Scomberomorus guttatus, Scomberomorus commerson, Rastrelliger kanagurta and Euthynnus affinis were selected for data collection. Data collections were conducted in three consecutive days in every 10 days, which covered nine days in a month. On each of the sampling days, types of fishing gears, total landings (kg), average length (TL in cm) and wholesale market prices for three important mackerels and one tuna species were recorded. Approximate proportion of selected mackerels and tuna caught by different gears were also recorded. Average total daily catch for a particular month was raised to monthly and then annual total catch for each of the species. Average daily catch was estimated. The seasonal variations of catches and percentage contributions of all species were also assessed. The size range, average size and_95% confidence limits of the size were calculated (TL in cm) for each month for each species. Finally, the price range, average price and total annual values of the catch of each of the species were estimated.

Achievement/Findings:

Total annual catch of the three mackerels and one tuna species was 1,718 t, which worth about 1,392 lakh taka. This annual contribution of mackerels and tuna could be increased many fold, if six other members of the group could be harvested properly. Therefore, the mackerel and tuna fishery are increasingly contributing to the marine fish production of the country and have glorious potential for further expansion for both domestic and export market. Nonetheless, due to the moderate market price but high quality flesh content, vast majority of the low-income coastal population are increasingly including the species in their diets, significantly contributing to the reduction of main utri ti on to the poorest of the poor people of Bangladesh.
