Abstract/ Executive Summary:

The study was carried out at Dhunat Upazilla under the district of Bogra for a period of four months from June to September 2002 to assess the diversity of fishing gears, catch assessment survey and the socio-economic condition of the riverine fishermen. The fishermen were found to follow various types of fishing gears and broadly categorized into three groups such as nets, traps and wounding gears. A total of 5 types of nets, 2 types of traps and one type of wounding gear were recorded. A total of 38 species of fishes were identified in the catches of different gears used by the fishermen. Among the different types of nets, the highest number of species recorded in the catches of sein net (25) which was followed by cast net (18) and relatively less number of species were recorded in the catch of push net (7). The average highest catch was obtained with the sein net was average 4.26 kg/ day) and the lowest with the (traps) Bair (the average 0.60 kg/day). It was found that Muslims were featuring as the absolute majority (66.67%) the Hindus were remarkably lower (33.33). The largest family size (8 persons) belongs to the seine net fishermen whose income was the highest (160/- TK/month) and the lowest family size (5 persons) was found among the current jal and the lowest income was found for long line fishermen (520 Tk/ month). it may be included that fish population in this river have declined alarmingly due to embankment erosion , indiscriminant gears used and absence of management policy for the open water resources of Bangladesh.

Keywords: Fishing diversity, Catch Assessment, Fishermen Community

Location: DHUNAT UPAZILLA, BOGRA.

Start Date: 00-06-2002

End Date: 00-09-2002

Program Area: Socio-economic and Policy

Commodity: Aquatic animal

Objectives:

To assess the diversity of fishing gears used in the study area,
To undertake a catch assessment and species composition and
To understand the socioeconomic condition of the fishermen.

Methodology:

Study Area: The study was conducted in the Jumuna River adjacent to the Dhunat Upazilla under the district Bogra during June to September 2002. The area of study side was about 4 km long with average depth 4.92 and wide 0.75 km. The river is an irregular shaped and in monsoon it is over flooded and affected the nearest villages. Fishermen Category: In the study area the fishermen communities were divided into two (2) distinct groups such as, professional fishermen and subsistence fishermen. Sixty (60) fishermen were selected from professional and subsistence fishermen groups. The samples and relevant data were collected once weekly throughout the study period. Sampling Procedure: Water samples were collected weekly at regular intervals from the Jamuna River. Type of Gear Used: There are many types of gear used in the Jamuna River. The gears were surveyed at 6 (six) hours’ intervals in each sampling day. A specially designed gear survey from was filled-up I.i by counting the gears. Catch Assessment Survey (CAS): Sapling of catches and their assessment were done once per week during the study period. The fishermen were selected on the basis of types of gear they operated. The total catches were weighed by a balance and the representative samples were taken with the help of hand without repetition of the same gear in each sampling day. The collected samples from different gears were taken in separate polythene bags gear-wise and brought to the Upazilla Fisheries Office, Shibganj, Bogra. The collected fishes were sorted species wise and the numbers of individuals for each species were counted and then their percent composition was determined. Preparation of Questionnaire: To collect data, preparation of questionnaire is very important. Before preparing the final questionnaire, a draft questionnaire was developed keeping in view the objectives of the study. The draft questionnaire was pre-tested in the study area by interviewing a few fishermen by the researcher himself. The questionnaire was then changed, modified and rearranged according to the experience gather in the testing. The final questionnaire was then developed in logical sequence, so that the fishermen could answer chronologically. Questions related to socio-demographic condition, income of fishermen and the family members, factors affecting the level of fish production and other relevant aspects of riverine fishing were included in the questionnaire. Collection of Data: To collect relevant data the single interview technique i.e. primary data were collected directly from the fishermen by the researcher himself. Several visits were made to the study area to collect accurate information related to objectives of the study. After each visits collected data were checked for accuracy and clarity.

Achievement/Findings:

The fishermen were found to follow three (3) fishing techniques viz , netting, trapping and angling. Within the fishing techniques three (3) types of fishing gears were recorded to be used by the fishermen for fishing. Among them (5) were fishing nets, two (2) fishing traps, one (1) wounding gear. A total of 38 species of fish were identified in the catches of different gears in this river. In case of nets the number of species was recorded in the catches of ber jal (25) , which was closely followed by jhaki jal (18). Relatively less number of species was recorded in the catches of current jal (13), dharma jal (15) and thela jal (7). in the traps , bair (5)and dharki (6) were found to catch a variety of species of fish. Wounding gear, borshi (8) caught more species of fish than the rest of the hooks and lines. Weekly average highest catch rates, CPUE (3.13 kg /gear) were recorded in nets and the lowest catch (0.40 kg / gear) in the traps. Socio economic condition of riverine fishermen communities were presented in terms of religion, family size and composition, educational status and income etc, in the present investigation, it was found that the Muslims were featuring as the absolute majority of the fishermen. About 66.67% and 33.33% riverine fishermen were the Muslims and Hindus respectively. The average monthly income of the berjal fishermen was the highest and they earned 20.97% income from fishing as the main occupation and average monthly income of thella jal fishermen was the lowest and they earned 6.81% income from fishing. it may be concluded that berjal fishermen were more efficient than other gears.
