Presented ByID No.: M130604037M.Sc. in Fisheries

Geographically Patharghata has been identified as one of the most important and promising area for marine fish. (Roy, B.J. 2010.)

Sharks, rays, and skates are of great commercial importance worldwide although shark fishery in Bangladesh is not a target fishery; its availability is incidental as by-catch (Haroon, A.K.Y., 2010).

A study was conducted to assess the effect of sun on drying shark fillet and fin at Pathargahata. It takes usually 7 to 8 days depending on weather.
