This common, coastal pelagic species forms large schools in bays, harbors and deep lagoons, usually in some turbid plankton-rich waters. It feeds on phytoplankton (diatoms) and small zooplankton (cladocerans, ostracods, larval polychaetes, etc.). There are many reports on life history and other information for this species compared to other Rastrelliger species (Noble and Geetha 1992). Size at first maturity is approximately 17-“20 cm (Tampubolon and Merta 1987, Sivadas et al. 2006), and longevity is estimated to be approximately four years (Mehanna 2001). This is a fast-growing species, and age at first maturity is expected to occur during the first year (Jayabalan et al. 2016). When applying an age at first reproduction of 1 years and longevity of 4 years, its estimated generation length is 2.5 years based on the following equation recommended by the IUCN Red List methods: Age at first reproduction + (Age at last reproduction -“ age at first reproduction)/2.
