Euthynnus lineatus, the black skipjack tuna or black skipjack, is a

Thunnini, better known as the tunas.[2]

Description

E. lineatus has a total of 10-15 spines in its

pelvic fins. Occasional specimens have extensive longitudinal stripes of light grey on their belly while other individuals have few or no such markings.[3]

Distribution

Eastern tropical Pacific from San Simeon, California to northern Peru and the Galápagos Islands.[4]

Fisheries

No targeted fishery exists for this species, though it is taken incidentally in the course of other fishery operations.[1]

Biology

E. lineatus is a pelagic and oceanodromous species which is rarely recorded where the surface temperature falls below 23 °C (73 °F). The larvae are most commonly found at temperatures higher than 26 °C (79 °F). It is generally distributed in surface waters which are no more than 386 kilometres (240 mi) from land. E. lineatus will form multi-species schools with yellowfin tuna and skipjack tuna. It shows opportunistic predatory behaviour, sharing its feeding pattern with other tunas, as well as dolphins and other large predatory fish, with which it also competes.[1]

The spawning of this species has a wide geographical and temporal distribution, and in the eastern tropical Pacific it has been shown to occur over a wide area from coastal to oceanic waters.[1]
