Threadfin (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Threadfins are silvery grey perciform marine fish of the family Polynemidae. Found in tropical to subtropical waters throughout the world, the threadfin family contains nine genera and 33 species. An unrelated species sometimes known by the name threadfin, Alectis indicus, is properly the Indian threadfish (family Carangidae). Ranging in length from 20 centimeters (7.9 in) in the black-finned threadfin (Polydactylus nigripinnis) to 200 centimeters (79 in) in fourfinger threadfins (Eleutheronema tetradactylum) and giant African threadfins (Polydactylus quadrifilis), threadfins are both important to commercial fisheries as a food fish, and popular among anglers.
