Taxonomy

Rarity

Rubberlip seaperch are the biggest surfperch there is, and the size is the reason to know them. The family runs to small, deep-bodied fish that live in the surf and around structure, and this is the one that reaches 18.5 inches. The California angling record is 5 pounds, taken in Monterey Bay in June 2009, and there is a separate California diving record of 4 pounds 10 ounces set at Carmel in 2012.

The species has never been assessed by the IUCN, which is the same situation as the barred surfperch and is not a statement about its condition. What is known is where the fish are thickest, and that is not southern California. The range runs from Mendocino County down to central Baja California, but abundance is centered from central Baja California up to San Francisco, with the greatest concentrations around Monterey Bay. A southern California diver sees rubberlip seaperch regularly without ever seeing them in the numbers that black perch or barred surfperch turn up in. California manages every member of the family under one rule, with a 20-fish aggregate outside San Francisco Bay and San Pablo Bay, no more than 10 of any single species, and no minimum size for anything except redtail surfperch.

Location

Rubberlip seaperch hold on shallow rocky reef, in kelp beds, along jetties and around pilings, and they school. That combination puts them in the same water as most of the fish a shore diver in California is already looking at. They range through the surf zone and into bays as well, and the depth range runs from a few feet down to about 165 feet, with some accounts recording them deeper still. A diver finds them by finding hard structure in shallow water, which is not a demanding search.

The mouth is what makes the species worth a second look. Rubberlip seaperch have thick, fleshy, pale lips that are the source of both common name and scientific name, which translates roughly as rag lip. Those lips are equipment. The fish feed mostly at night on thin-shelled invertebrates, taking crabs, shrimp and octopus, and they locate and sort their food by touch rather than by sight, using the lips to separate what is edible from the debris on the bottom. Juveniles work the same way on smaller prey, taking little crabs, mussels, snails and marine worms. A rubberlip seen resting near structure in daylight is a fish between shifts.

Like every surfperch, this species gives birth to live young rather than laying eggs. No California birth season specific to rubberlip turned up, though anglers report the meat is better outside the spawning period.

Spearfishing Brief

There is no dedicated hunting account for this species anywhere in print, which is worth saying plainly, but there is a California diving record, so people take them. The ratings here follow from the documented habits of the fish and from where the other surfperches in this Ichthyopedia sit.

Finding one rates a 2. Rubberlip seaperch school on shallow rocky reef, in kelp, and around jetties and pilings, all of which are the first places a shore diver looks anyway. They are not camouflaged and they are not cryptic. What keeps this above a 1 is abundance rather than visibility: they are simply less numerous in southern California than black perch or barred surfperch, so a diver may search several patches of reef before finding a school.

The shot also rates a 2, and it matches pile perch. This is a deep-bodied fish holding near structure in shallow water, which tolerates a controlled, unhurried approach in a way an open-water schooling fish never does. It is warier than black perch or zebra perch, both of which this Ichthyopedia rates a 1, and it is bigger, so the target is easier. Overall difficulty is 2.

Weapon choice separates rubberlip from its smaller relatives. A pole spear is enough for a 10-inch black perch. An 18-inch fish over 4 pounds is worth a short shore-diving speargun, the same 40 to 50 inch, 2-band setup that covers pile perch and most shallow reef work in California. No reel or float is needed, because the fish holds to structure and does not run far.

The table is where rubberlip earns its place. The meat is the same as every other surfperch, which is to say mild, small-flaked, soft and low in fat, and most people who write about it rate the flavor as fair rather than good. What changes the arithmetic is size. A surfperch fillet is usually a token, and this fish is large enough that the fillets are worth cutting instead of cooking the fish whole. Anglers also report the meat is better outside the spawning season. Pan-frying, grilling and baking all work.

Deep Dive

The name is honest. The lips of a rubberlip seaperch are thick, pale and fleshy in a way no other California surfperch matches, and they are the reason the fish exists in the shape it does. Rubberlip feed at night on soft-bodied and thin-shelled animals sitting on the bottom, and finding those animals in the dark is not a job for eyes. The lips do it by touch, picking through sediment, shell fragments and drifting debris to separate food from everything else. It is the same problem a shorebird solves with a long bill. Rubberlip solved it with a mouth built like a pair of fingers.

That diet also explains where the fish live. Crabs, shrimp and octopus mean rock and kelp, not sand, which is why rubberlip hold on reef and around pilings rather than out in the trough with the barred surfperch. Juveniles take smaller versions of the same food, eating mussels, snails and marine worms until they are big enough for crabs.

Size is the other defining fact, and it is worth measuring against the family. Most surfperches top out around a foot. This one reaches 18.5 inches and lives to about 10 years, and nothing else in the family gets there. For a California diver that means a rubberlip is the only surfperch that reads at a distance as a substantial fish rather than as reef filler.

The species also sits inside one of the odder legal categories in California fishing. State regulations define surfperch as every species of the family in any combination, then set a single aggregate limit across all of them, 20 fish outside San Francisco Bay and San Pablo Bay with no more than 10 of any 1 species. That means a diver who takes 10 black perch and 10 rubberlip has a full limit, and a diver who takes 20 of anything from the family has one too. The only member with a minimum size is the redtail surfperch, at 10 and a half inches, and the only seasonal closure is in San Francisco Bay and San Pablo Bay from April 1 through July 31, which is a protection for the spring birthing period in those waters and does not apply anywhere on the southern California coast.

One more thing about this family, since it applies here and is easy to forget. Surfperches do not lay eggs. The female carries the young inside her and gives birth to fully formed fish, which is rare among ocean fish and is the reason a surfperch caught in spring is often visibly heavy. That biology puts a ceiling on how fast a population can rebuild, because a fish that carries its young to full size cannot produce them in the numbers a fish releasing a million eggs into open water can. It is the argument behind treating the whole family under one conservative limit rather than species by species.
