Hardenberg's anchovy (Stolephorus insularis) fish species information

Scientific Name
Stolephorus insularis

Common Name
Hardenberg's anchovy

Biology
A schooling species occurring in coastal waters. More data needed based on correct identifications. The record from the Godavari estuary implies tolerance of lowered salinities, but the identity of the material is uncertain (perhaps S. waitei). Appears to be fairly common throughout its range. Used as bait in the tuna fishery in the South Pacific, although rather fragile.
