Highfin Amberjack

Seriola rivoliana

Summary 2

Almaco jack (Seriola rivoliana) is a game fish of the family Carangidae; they are in the same family as yellowtail and amberjack. They feed, both day and night, on other smaller fish such as baitfish and small squid. The flesh is thick and dense like tuna and can easily pass for white albacore if prepared as sushi.

Description 3

The longfin yellowtail has a less elongated, more flattened body than most jack species. Their dorsal fin and anal fins are elongated, and their outer edges have a definite sickle shape. The first rays of the almaco dorsal fin's longest parts are nearly twice as long as the dorsal spines, also different from other jacks.

They reach a typical length of 90 centimetres (35 in), sometimes reaching 160 centimetres (63 in) and 59.9 kilograms (132 lb). Typical catch is approximately ten pounds, however, according to the Florida Fish and Wildlife Conservation Commission, which describes it as wide-ranging in small groups and not a common catch.

Generally, longfin yellowtails are dusky-colored with faint amber or olive stripes down their sides. Their upper bodies and lower fins usually are dark brown or dark blue-green. The belly is much lighter and appears brassy or lavender. The nuchal bar and most of the fins are dark on adults. Exceptions are the pelvic fins which are white on the ventral sides.
