At a glance

Sources stay attached to every fact

Identity

A dolphinfish in the family Coryphaenidae, unrelated to marine mammals. California and NOAA recognize Coryphaena hippurus.

Habitat

Warm open-ocean surface waters, frequently near floating objects, weed lines, current edges, and concentrated forage.

Primary foods

An active predator of small pelagic fishes, squid, and crustaceans near the surface.

Regulation posture

Verify current California pelagic finfish bag, possession, fillet, and jurisdiction rules before keeping dorado, especially on cross-border trips.

The dorsal fin begins near the head and runs nearly the entire length of the back. Live fish show iridescent blue and green above with golden sides and scattered spots. A blunt forehead—especially in males—and a deeply forked tail create the unmistakable silhouette.

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.

Field context

A rapidly growing pelagic fish. Mature males can develop a tall, nearly vertical forehead while females retain a more rounded head profile.

Availability is not a promiseSouthern California seasonality
Planning context

Southern California appearances depend strongly on warm offshore water and current conditions; recent landings are more useful than a fixed calendar promise.

Decide before the fish reaches the railHandling & 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.
