Black skipjack tuna (Euthynnus lineatus)
Warm-water species endemic to the eastern tropical Pacific. It ranges from San Simeon (California) and the lower half of the Gulf of California to northern Peru, including all the offshore islands and the Galapagos. It is mostly found in surface waters but more offshore than other species of the same genus, within about 450 km off the mainland. Black skipjack inhabits warm waters where surface temperatures are at least 23°C, but the average water temperature where this species is mostly caught is 29.2°C (Collette and Graves, 2019).
