Mainly a coastal marine species, forming large schools. Tolerates salinities of 5-41 ppt and in some areas, enters lagoons, estuaries and lakes, especially during spawning. Tends to move further north and into surface waters in summer, retreating and descending in winter. Feeds on planktonic organisms. Spawns from April to November with peaks usually in the warmest months. Eggs are ellipsoidal to oval, floating in the upper 50 m and hatching in 24-65 hours. Marketed fresh, dried, smoked, canned and frozen; made into fish meal (Ref. 9987).
Pelagic spawners. Gametogenesis is continuous, multiple spawning. Spawning peaks are usually in the warmer months which makes this species a spring-summer spawner. The limits of the spawning season is dependent on temperature and is therefore more restricted in northern areas. Sex ratio: 45% female (Ref. 5580).
