Abstract/ Executive Summary:

Studies were conducted on catch assessment of some artisanal marine fishing gears operated in Cox’s Bazar and Teknaf areas from April 2014 to April 2015. Sixteen types of fishing gears were identified, of which gill net, beach seine net, estuarine set bag net, marine set bag net and trammel net occupy major fishing activities. Although estuarine set bag net (ESBN) is a legally restricted fishing gear recorded the highest catch per unit effort (CPUE) (110 kg/gear/day) in July followed by marine set bag net (MSBN) (105 kg/gear/day) in Cox’s Bazar and the highest CPUE was recorded 100 kg/gear/day by ESBN in June followed by MSBN (90 kg/gear/day) in Teknaf. Out of 52 species of fishes, the major fish species abundantly caught by these gears were Poa (Otolithoides argenteus), Churi (Trichiurus haumela), Loittya (Harpadon nehereus), Ranga choukha (Lutjanus johni), Lal poa (Johnius argentatus), Olua (Coilia dussumieri), Rup chanda (Stromateus chinensis), (Stromateus argenteus) and Ilish (Tenualosa ilisha). Besides these fish species, 10 commercially important shrimp species and 3 important crab species were also recorded during the study period. The peak season of availability of most fish species was June and July while lean season was December and January. This study indicated that Otolithoides argenteus) was the dominant fish species followed by Trichiurus haumela, Harpadon nehereus and Coilia dussumieri.

Location: Teknaf and Cox's Baza

Start Date: 00-04-2014

End Date: 00-04-2015

Program Area: Resource Development and Management

Commodity: Marine fish

Objectives:

To investigate the types and characteristics of artisanal marine fishing gears operated in the Cox’s Bazar and Teknaf region, and their catch composition and seasonality of operation.

Methodology:

Study Area- The study was conducted in Teknaf and Cox's Bazar areas because of greater importance of these two areas for artisanal fishing activities. Data Collection- Primary data were collected by field survey that involved the investigation of the study areas in terms of artisanal marine fishing gears, particulars of operation, catch composition, seasonal abundance and species composition of fish. Data were collected from April 2014 to April 2015 where a total of 106 fishermen were interviewed with a combination of field survey, questionnaire interviews and participatory rural appraisal (PRA) methods viz. focus group discussion (FGD). A total of 7 FGD sessions were conducted in the study areas where each group had 10 to 20 persons and duration of FGD was approximately two hours. Thereafter data were cross-checked with proper authorization like Upazilla Fisheries Officer (UFO), Manager of BFDC for the accuracy of collected primary data. Data Processing and Analysis- All the collected primary data were analyzed through simple statistical methods using Microsoft excel

Achievement/Findings:

This study concludes that there is very little or no change in fishing activities over the last two decades in Cox’s Bazar and Teknaf and there is almost no evidence of introducing new fishing gears. Fishermen are using the common fishing gears for fishing in marine areas. One of the major findings of this research shows that there is a fishing pressure in the study areas. The main reason which is markedly evident is the easy access in the water body for fishing and limitations in implementations of rules and regulations.
