Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 9; Mjukstrålar i ryggfenan (totalt) : 22 - 25; Taggstrålar i analfenan: 3; Mjukstrålar i analfenan: 19 - 21. Diagnosis: body elongate (depth comprised 3.2-3.5 times in fork length) and moderately compressed; snout slightly rounded (Ref. 57392). Maxilla ends below middle of eye (Ref. 26938, 57391). 2 dorsal fins, 1st with 8 spines, 2nd with 1 spine and 22-25 soft rays; anal fin with 2 spines, followed by 1 spine and 19-21 soft rays (Ref. 57391, 81654). Anterior lobe of soft dorsal and anal fins moderately developed, their height smaller than head length; pectoral fins falcate, longer than head; scales small and cycloid (Ref. 57391). Chest fully scaled (erroneously reported as chest naked in other sources)(Ref. 81654). 45 (Ref. 26938, 81654) - 56 (Ref. 57392, 81654) scutes along posterior/straight part of lateral line. Coloration: back light olivaceous to bluish-green, sides silvery-grey to golden; juveniles with about 7 dark crossbars on sides (Ref. 57392).

Biologi     Ordlista (t.ex. epibenthic)

A schooling species (Ref. 5217, 57391) generally not far from the coast (Ref. 5217), in coastal marine and brackish waters to at least 100 m depth (Ref. 57392). Juveniles often found in association with floating Sargassum (Ref. 5217), often entering lagoons and estuaries (Ref. 57392). Adults feed on fishes, shrimps, and other invertebrates. They spawn offshore from January through August (Ref. 26938). Eggs are pelagic (Ref. 4233). Excellent food fish (Ref. 9626); marketed fresh, frozen (Ref. 5521), and salted. Often used for bait (Ref. 26938). Maximum reported total length 550mm in Ref. 57392.
