The study describes traditional fishing gears and crafts available at Gumti river of Muradnagarupazila in Cumilla district, Bangladesh. The study was carried out by the collection of primary data through surveying individual fishermen. We found that there are 6 fishing gears available in the study area. Among them, 5 types of the fishing net (i.e., cast nets, seine net, lift net, push net, gill net) and a kind of fishing trap was identified. We also found 4 different types of crafts, including dinginauka, koshanauka, chandinauka, and sototempu. Synthetic twines are used for net making, which increases the fishing efficiency significantly. The life span of these nets varies according to their building materials. Sun-drying was the best approach for net preservation rather than using any chemicals or medicine. Besides, traditionally mehogany, raintree, shill koroi, garjan, gamari, jarul, chapulis woods and bamboos were found to be boat construction materials. The boats are painted with tar or pitch and burn oil for the protection. No modern instruments such as a compass, life-saving equipment are used by these boats. Most of the boats are mechanized, i.e. operated by engine. Asian J. Med. Biol. Res. September 2020, 6(3): 469-474

In the present study, the edible portions of whole fish excluding viscera and bone of five different freshwater fish species samples are analysed for lead, manganese, nickel, zinc, copper and iron by atomic absorption spectrophotometry (AAS). The relative standard deviations (RSD) were found below 5%. The accuracy of the methods was confirmed by certified reference materials. The concentrations of trace elements in the edible portions of other fish comply with the international standards for human consumption.
