Program Area: Resource Development and Management

Commodity: Fish

Objectives:

The present research includes the description of seasonal availability, breeding season, status of 78 species of fishes under 48 genera, 19 families, 9 orders and 1 class.

Methodology:

The study area is located on the eastern bank of the river Atrai and it covered from Chotkighasa to Casiabari hat of Naogaon district. The fish species were collected and identified directly from the local place. Monthly visits were made in the fish markets of Ahsangong hat and Casiabari hat during the study period. Visits to the fish-landing centers of Atrai station, Kumghat, Shahebgong and Chotkighasa area were also made almost once in a week throughout the study period, which started from August 2005 to July 2006. The specimens were identified with the help of books and systematically categorized. Identification was made following the key of Bhuiyan (1964), Rahman (1989), Talwar and Jhingran (1991) and Bhuiyan et al. (1992).

Achievement/Findings:

The present study is an attempt to identify the fishes and non-fin fishes available in the river Atrai near Naogaon region. As many as 78 fish species and 11 fisheries items were identified during the study period. The richness of the river Atrai with regard to fisheries resources have been greatly affected due to degradation of habitat through pollution, siltration, soil erosion, impact of barrage and flood control structures that have modified the natural route of the rivers and overfishing trend as well as the use of banned fishing gear endangering many fish species and also fisheries items. For coservation and propagation of the endangered fish species from further degradation now it is necessary to provide suitable habitat for food, shelter and breeding of endangered fish species moreover standardization of spawn and fry collection method is necessary for further sustainability of the fisheries resources of the river Atrai.
