The document summarizes a study on the sun drying process of shark fillets and fins in Patharghata, Barguna, Bangladesh. The study assessed the time required to dry shark fillets and fins using data collected from June 2009 to May 2010 through interviews, surveys, and laboratory analysis. The results showed that it takes 7-8 days to dry shark fillets and fins depending on weather conditions, with weight loss occurring steadily each day as moisture is removed through sun drying. Samples were collected from the Bangladesh Fisheries Development Corporation in Patharghata to monitor weight changes during the drying process over multiple days.

3.  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.
