Despite the name, white seabass is California's largest croaker. Read the long silver body, large mouth, belly ridge, dark side specks, and black pectoral-base mark together.


- Large mouthThe head carries a large mouth without the prominent paired canine teeth used to separate shortfin corvina.
- Speckled silver sidesAdults are gray-blue to copper above with dark side specks and a silver belly; juveniles can show bars.
- Pectoral-base markLook for the black spot at the inner base of the pectoral fin plus the raised ridge along the belly.

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
Use tackle strong enough to land the fish without an exhausting fight, and keep a dehooker or suitable release tool ready.
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.
Face a sluggish fish into the current until it can swim away under its own power.
