📖 Overview

Forms schools in shallow waters, the juveniles apparently entering the lower parts of rivers, but returning later to the sea. Feeds on both zooplankton (copepods, crab zoea, larvae of bivalves and fish eggs) and phytoplankton. Breeds from October to February (mainly November to January) off western coast of India, usually in relatively shallow inshore waters. Marketed fresh and dried-salted.
