Oblique-jaw thryssa
📖 Overview
Presumably schooling, occurring mostly inshore and entering estuaries and also Lake Chilka in India, thus able to tolerate lowered salinities. More data needed based on correct identifications. If this is the species being referred to in Ref. 6841, then the young feeds on surface plankton, chiefly on prawn larvae, but also small fishes (e.g. Stolephorus) and cypris. Apparently common.
