A Complete Structure and Design of a Gillnet

Rex Dunham

Worldwide, gillnet is one of the maximum vital fishing gears for harvesting a lot of species with inside the sea and in freshwater. Gillnets are efficient, catching a various variety of species, and are distinctly length selective. However, gillnets have confined species selectivity and on occasion capture non-goal species; birds; and megafauna species which includes cetaceans, turtles, and sharks. Lost gillnets regularly keep to fish, a state of affairs referred to as “ghost fishing”, losing precious resources. This paper describes primary additives of a gillnet and it’s fishing mechanisms, and opinions capture efficiency, selectivity and associated conservation issues.
