Maturity: Lm 85.0, range 55 - 82 cm
Max length : 240 cm FL mâle / non sexé; (Ref. 5765); common length : 120 cm TL mâle / non sexé; (Ref. 5450); poids max. publié: 70.0 kg (Ref. 5765)
Épines dorsales (Total): 15 - 18; Rayons mous dorsaux (Total): 15-20; Épines anales 0; Rayons mous anaux: 16 - 21; Vertèbres: 42 - 46. Interpelvic process small and bifid. Swim bladder absent. Lateral line abruptly bent downward below end of second dorsal fin. Intestine with 2 folds and 3 limbs. Vertical bars on trunk sometimes break up into spots ventrally which number 40-50 in adults, and less than 20 in juveniles. Juveniles with large oval dark spots on body; middle third of first dorsal fin white, rest of fin black (Ref. 11228).
Distributed from near edge of continental shelf to shallow coastal waters, often of low salinity and high turbidity (Ref. 30199, 48637). Also found in drop-offs, and shallow or gently sloping reef and lagoon waters (Ref. 1602, 48637). Usually hunts solitary and often swim in shallow water along coastal slopes (Ref. 48637). Known to undertake lengthy long-shore migrations, but permanent resident populations also seem to exist. Found in small schools (Ref. 9684). Feed primarily on small fishes like anchovies, clupeids, carangids, also squids and penaeoid shrimps. Eggs and larvae are pelagic (Ref. 6769). A lipid-soluble toxin, similar to ciguatoxin has been found in the flesh of specimens caught on the east coast of Queensland, Australia. Marketed fresh, dried-salted (Ref. 9684), frozen, smoked, and canned (Ref. 9987); commonly made into fish balls.
Depending on temperature regime, the spawning season may be more or less extended.
In Australian waters, each female spawns several times over the season, about 2 to 6 days apart (Ref. 30196), depending on the locality. Spanish mackerel spawn off the reef slopes and edges, and they form spawning aggregations in specific areas (Ref. 6390).
