Herring Cale

Olisthops cyanomelas

Herring Cale (Olisthops cyanomelas) is a small marine fish of Australian temperate waters, often schooling near coastal reefs and kelp. It is not a common angling target, and published species-specific fishing information is limited.

Identification points

Slender, small-bodied coastal fish with a silvery to bluish-green sheen
Distinct dark lateral markings/blue-gray banding on the body
Small mouth and forked tail, typical of open-water schooling fish

Habitat

Temperate coastal marine habitats, especially shallow reefs, kelp beds, seagrass edges, and sheltered rocky coastlines around southern Australia; commonly schools inshore and near structure.

Bait notes

Not a mainstream game species. If targeted incidentally, very small bits of prawn, marine worm, or tiny soft plastics/flies imitating planktonic bait are most plausible; light, subtle offerings work best.

Behavior

Forms loose schools and feeds on small zooplankton, tiny crustaceans, and other planktonic prey in the water column. It is generally a midwater to surface-oriented coastal fish rather than a bottom feeder.

Caution

No notable species-specific hazards are well documented; handle gently and check local rules, as regulations and protected status may vary by region.

Fishing notes

Use very light tackle near kelp edges, reefs, and bait schools; small hooks and minimal weight help when fish are feeding high in the water column. Most captures are likely by accident while fishing for other coastal species.
