Ecology of Rastrelliger kanagurta
 
Main Ref. Collette, B.B. and C.E. Nauen, 1983
Remarks Juveniles feed on phytoplankton (e.g., diatoms) and small zooplankton such as cladoceran, ostracods, larval polychaetes, etc. With growth, they gradually change their dietary habits, a process that is reflected in the relative shortening of the intestine (Ref. 30531). Pelagic migratory fish. Prefers open but protected coastal waters. Shoaling species. Juveniles feed on diatoms, Diplostraca, and Ostracoda, while adults feed on macroplankton, larval shrimp and fish (Ref. 9773).
