The head is rounded with a comparatively small mouth, unlike the large jaw of a white seabass. A single long low dorsal fin follows most of the back without the tuna-like gap and finlets. The narrow tail base and deep fork combine with a blue-gray back and pale silver sides.

Confirm before keeping

Use body shape, fin placement, color pattern, and the official California identification resources together. Never make a keep decision from one color mark or a count-category name alone.

Handling & release

Prepare to release

Use tackle strong enough to land the fish without an exhausting fight, and keep a dehooker or suitable release tool ready.

Minimize harm

If releasing, dehook in the water when possible. Never gaff a fish you plan to release, keep air exposure brief, wet your hands, avoid eyes and gills, and support the body rather than hanging the fish by its mouth.

Release with strength

Face a sluggish fish into the current until it can swim away under its own power.
