Description

The silver-stripe round herring is a small herring-like fish of the family Clupeidae from the Indo-Pacific. The species grows to about 10 cm and has a slender, roundish, translucent body with a conspicuous shining silver lateral stripe. It forms dense schools in relatively clear inshore coastal waters. As a plankton feeder it feeds on small zooplankton. As an extremely abundant prey fish it is an important link in the food web and a widely used bait fish for the tuna fishery. Owing to its small size the species is harmless to humans.
