Opaleye

Girella nigricans

Opaleye is a herbivorous surf-zone and shallow reef fish of the eastern Pacific, common around kelp beds, rocky reefs, jetties, and tide pools. It grazes on algae and often schools in shallow, clear water near cover.

Identification points

Oval, laterally compressed body with a small mouth
Olive to brassy body with silvery-blue sheen on the sides
Dark vertical bars or mottling on the sides, especially in juveniles

Habitat

Shallow rocky reefs, kelp forests, tide pools, surf lines, jetties, and pilings in coastal water, especially where algae grows on hard substrate.

Bait notes

Best taken on small natural baits such as fresh mussel, shrimp, clam, squid strips, or seaweed/kelp-tipped hooks. Small pieces and light terminal tackle work better than large offerings.

Behavior

Mostly diurnal and wary; adults graze on algae and small invertebrates, while juveniles stay in very shallow protected water. They often school and spook easily in clear water.

Caution

Sharp gill plates and spiny fins can cause cuts. Check local regulations and size limits; coastal reef fish can also accumulate contaminants, so follow regional consumption advisories.

Fishing notes

Use ultra-light or light tackle, small hooks, and a stealthy approach around rocks, kelp edges, and jetties. Present baits near bottom or drift lightly through surf wash; small floats can help keep baits just off the rocks.
