Black skipjack (Euthynnus lineatus) is a saltwater species recorded in the United States. It is found at depths of 0–40 m.
Scientific name: Euthynnus lineatus · Water: Saltwater
Size: up to 84 cm
The black skipjack is an oceanic scombrid that occurs rarely where surface temperatures fall below 23 degrees Celsius, and its larvae are more frequently encountered above 26 degrees Celsius and are practically confined to waters within about 240 miles of the mainland. It inhabits near the surface of coastal and offshore waters, forms multi-species schools with yellowfin and skipjack tuna, and is an opportunistic predator that shares its feeding pattern with other tunas and probably competes for food with species such as yellowfin tuna, the common dolphin and the oriental bonito. It is recorded from the surface down to 40 m. Maximum length is about 84 cm fork length, commonly about 60 cm fork length. It is a minor commercial species and a gamefish, with a high price category. Fishing vulnerability is moderate at 43 of 100 and resilience medium, and climate vulnerability is very high at 88 of 100. IUCN lists it as least concern.
