Diagnostic Description
provided by Fishbase
Interpelvic process small and bifid. Lateral line gradually curving down toward caudal peduncle. Intestine with 2 folds and 3 limbs. Swim bladder absent. Body covered with small scales. Juveniles (less than 10 cm) marked with 12-20 vertical bands which becomes less distinct or break into spots in larger fish.
Migration
provided by Fishbase
Oceanodromous. Migrating within oceans typically between spawning and different feeding areas, as tunas do. Migrations should be cyclical and predictable and cover more than 100 km.
Morphology
provided by Fishbase
Dorsal spines (total): 13 - 15; Dorsal soft rays (total): 19 - 22; Analspines: 0; Analsoft rays: 19 - 22; Vertebrae: 44 - 46
Trophic Strategy
provided by Fishbase
Pelagic species which is generally captured in inshore waters of higher turbidity than waters frequented by school (S. queenslandicus) or spotted (S. munroi) mackerel (Ref. 30572). There is some evidence that larvae and juveniles are dependent on estuarine and coastal nursery habitats (Ref. 30572).
Biology
provided by Fishbase
Found more commonly around coastal headlands and rocky reefs but are also caught offshore (Ref. 6390). Juveniles (4.5 to 10 cm length) are commonly encountered during November along the beaches of Townsville, Queensland and grow to twice this size by January. They are pelagic predators, feeding exclusively on baitfish (sardines and herrings (Ref. 30572). Caught also with set lines aside from trolling with small lures or cut bait. Marketed fresh and frozen; eaten fried, broiled and baked (Ref. 9988).
