Young Scombroid Fishes from the Gulf of Mexico
Abstract:Examination of some fish collections, made in the Gulf of Mexico from June, 1954 to August, 1956 by personnel of the United States Fish and Wildlife Service, have resulted in the separation and identification of young forms of several tuna and tuna-like species. These include the yellowfin tuna (Thunnus argentivittatus), blackfin tuna (Thunnus atlanticus), oceanic skipjack (Katsuwonus pelamis), little tunny (Euthynnus alletteratus), frigate mackerel (Auxis thazard), and bonito (Sarda sarda), as well as a few small specimens of Thunnus of indeterminate species. The methods of diagnosis employed are discussed, and some species are described and illustrated.
The capture of these young fishes indicates that several scombroid species spawn in the Gulf of Mexico at various times of the year.
