Rainbow Seaperch
Rainbow seaperch from the Fort Baker Pier
Species: Hypsurus caryi (Agassiz, 1853); from the Greek word hyps (high), the Latin word urus (a kind of wild ox) and Greek word cary (a nut)—apparently in reference to the shape.

Rainbow seaperch from the North T-Pier in Morro Bay
Identification: One of the most beautiful fish in California, rainbow seaperch have a typical perch-like shape, although they’re more elongated then striped seaperch and black seaperch. They have red and blue stripes on the sides, bright blue and red-orange pelvic fins, and a dark spot on the soft dorsal fin rays and anal fin. The area between the pelvic and anal fins is flat. For some reason anglers seem to constantly confuse rainbow seaperch and striped seaperch calling each the name of the other. They are actually very easy to identify once pictures and identification (such as this) are consulted.

Rainbow seaperch at the Fort Baker Pier
Piers: Rainbow seaperch are common at only a few piers. Best bets: Gaviota Pier, Coast Guard Pier (Monterey), Monterey Wharf #2, Santa Cruz Wharf, Fort Point Pier, San Francisco Municipal Pier, Elephant Rock Pier, Fort Baker Pier.
Shoreline: A favored catch for rocky shore anglers in southern and central California.
Boats: An inshore species rarely taken by boaters.
Bait and Tackle: These small perch are best taken with small size 6 or 8 hooks tied directly to your line, or by using a high/low leader. Best baits are fresh mussels, pile worms or small live rock crabs. Fish directly on the bottom.
STRIPED SEAPERCH from the Trinidad Pier. Often confused with the rainbow seaperch but note the horizontal stripes.
Food Value: Fair, although they’re almost too pretty to keep. Their flesh is mild in flavor with small flakes and soft texture. They taste best during the non-spawning season, are low in fat content, and can be cooked using most methods. Many try to remove the loose hair-like bones as much as possible through filleting the fish (if large enough). We recommend returning all pregnant perch to the water if for no other reason than their meat is generally subpar during their pregnancy (the nutrients in their system being used for the babies which they birth live).
Comments: These fish, along with striped seaperch and pileperch, often enter central and northern California streams and spawn in the tidewater areas, when they do fish will be caught on nearly every cast. They put up a spirited fight, but for me, their beauty and fairly small size warrants a return to the water.
