Bluestripe herring (Herklotsichthys quadrimaculatus) fish species information

Scientific Name
Herklotsichthys quadrimaculatus

Common Name
Bluestripe herring

Biology
Adults form schools near mangroves, shallow coastal bays and lagoons during the day and moves further offshore into deeper water by night (Ref. 188, 48635). Known in mills around in large schools under wharves or along sandy beaches in protected bays (Ref. 26367). Are pelagic (Ref. 58302). Feeding occurs mainly at night on zooplankton, chiefly copepods by juveniles, and as adults, on larger prey organisms (chaetognaths, polychaetes, shrimps and small fishes). Breeding occurs on the first year and probably survive only a few months after maturity. Marketed fresh and dried salted (Ref. 188). Usually parceled in leaves and baked in a motu oven. Do not recover quite as quickly as other species of baitfish after heavy fishing (Ref. 26367).

Distribution
Indo-West Pacific: widespread, East Africa, Madagascar, Mauritius eastward to Japan, eastern Australia, Samoa. Introduced into Hawaii - apparently by accident - where it is now abundant. (most previous data published under the name Herklotsichthys punctatus). At least one country reports adverse ecological impact after introduction.
