Taxonomy

Rarity

Striped seaperch is one of the most commonly caught surfperch in California and one of the least likely to turn up on a southern California mainland dive. Both statements come from the same table. State records list it among the 7 most commonly caught species in the family, with an average of 82,000 fish taken each year, and then note that 97 percent of that catch comes from north of Point Conception. Only 3 percent is southern, which makes this the most northern-weighted surfperch there is.

The distribution is not a smooth fade, which is the useful part. California pier-fishing literature describes the species as common from the northern Channel Islands north to British Columbia, uncommon through most of the southern California mainland, and then common again in northern Baja California. A diver at Santa Cruz Island or Anacapa can expect them. A diver at La Jolla mostly cannot, and the fish that do appear tend to be single animals rather than the schools that northern divers see.

Unlike most of the family, this species has a real conservation assessment. The IUCN lists it as Least Concern, evaluated in 2018. The state's own trend numbers are less cheerful, with catch down 44 percent and catch per 1000 angler hours down 40 percent between the 1980s and the 1990s survey periods. It is also 1 of the 4 species that dominated California's commercial surfperch landings in the 1930s and had each fallen below 1 percent of identified landings by the 1990s.

California treats the whole family as one animal, with a daily limit of 20 fish in combination and no more than 10 of any 1 species. Striped seaperch has no minimum size.

Location

Striped seaperch range from southeastern Alaska down to central Baja California. They belong to the rocky reef biome first and the kelp forest biome alongside it, and they also work the bay biome, turning up in bays and estuaries through much of the range. Occasionally they appear in sandy surf, but only where sand sits directly against rock.

Position in the water column is the thing to know. Striped seaperch hold near the bottom, close to the reef, rather than up in mid-water or in the canopy. That habit puts them in exactly the ground a shore diver works and makes them a bottom-searching find rather than something spotted from above. The recorded depth range runs to about 95 feet, with community reports past 300, though nearly every encounter happens shallow.

This is a genuinely beautiful fish and the identification reflects that. The ground color is copper, darkening to brown across the back, and running along the sides below the lateral line is a series of roughly 15 narrow horizontal stripes in blue and orange. The head carries its own separate pattern of blue spots and short stripes. The body is deep and strongly compressed, the dorsal spines are low, and the fins are coppery. Both dark and light color forms occur.

The confusion to guard against is with the rainbow seaperch, which is also striped, also blue and orange, and lives on the same rocky ground. Rainbow seaperch are more elongated, less deep-bodied, and carry a dark spot on the soft rays of the dorsal fin and on the anal fin. Striped seaperch carry no such spot and are the heavier, rounder animal of the 2.

The diet is broad by family standards. Striped seaperch take small crustaceans, marine worms, mussels, snails, bryozoans and algae off the reef, and they also eat fish eggs, with herring eggs specifically recorded. That last item is a northern behavior tied to the herring spawn, and it is one reason the species is a much bigger presence in Puget Sound and British Columbia than it is off San Diego.

Spearfishing Brief

No dedicated account of spearing striped seaperch exists in print. The ratings here follow from the documented habits of the fish and from the other structure-holding perches already in this Ichthyopedia.

Finding one rates a 3, and the number is about scarcity rather than concealment. This fish is neither camouflaged nor cryptic; it is simply not there most of the time on the southern California mainland, where only 3 percent of the state catch is taken. A diver at the northern Channel Islands should mentally drop that rating to a 1, because there the species is common and holds in numbers. The 3 describes the water most of this site's divers are actually in.

The shot rates a 2. Once found, this is a favorable target: a deep-bodied fish up to 15 inches, holding near the bottom against rock, which tolerates a slow and deliberate approach in a way an open-water schooling fish never does. It sits 1 step above the black perch, which this Ichthyopedia rates a 1, because it is warier and less habituated to divers, and level with pile perch and rubberlip seaperch. Overall difficulty is 3, taking the harder of the 2 numbers.

Weapon choice follows size. At up to 15 inches this is one of the larger surfperch, in the same class as pile perch and rubberlip, and it earns a short shore-diving speargun rather than a pole spear. No reel or float is needed, because a fish holding to structure does not run far.

The table is solid rather than remarkable. Striped seaperch is among the surfperch large enough that anglers describe it as worth eating instead of worth releasing, and the flesh is the family standard: white, mild, low in fat, finely flaked and soft, cooking well by most methods. It is reported to taste better outside the spawning season, which is also the sensible time to leave the biggest fish alone, since in spring those are the pregnant females.

Deep Dive

Anyone who has landed a big striped seaperch in spring has met the strangest thing about this family, usually without warning. The largest fish in the school at that time of year are females carrying a full brood, and a brood in this species runs from 9 to as many as 92 young, the widest range recorded for any California surfperch in the state's summary table. Bring one over the rail in April and she may simply start giving birth, delivering dozens of small, complete, swimming fish into a bucket. California pier-fishing literature describes this happening often enough that anglers have developed settled opinions about what to do next, with some keeping the young as bait, some returning them to the water, and some refusing to keep gravid females at all.

The reason it is startling is that almost no other ocean fish works this way. The standard marine strategy is to release enormous numbers of eggs into open water and accept that nearly all of them will be eaten. Surfperch do the opposite. Fertilization is internal, the female stores sperm for months, the young develop inside her, and what is born is not a larva but a fish, able to swim and feed from the first minute. Striped seaperch mate in fall and give birth the following summer.

The trade is straightforward. Very few offspring, each with a very high chance of surviving its first week. It is an excellent design in a stable environment and a fragile one under sustained pressure, because a population producing dozens of young per female per year cannot rebuild at the speed of one producing millions. That single fact sits underneath every management decision California has made about this family, including the 2002 cut in recreational limits and the closed spring season in San Francisco Bay.

There is also a movement worth knowing about, because it is unusual for a marine fish. Striped seaperch, along with rainbow seaperch and pile perch, are recorded entering central and northern California streams and gathering in the tidewater reaches to give birth. These are not migrations in the salmon sense and the fish are not going far, but a saltwater perch pushing up into the brackish lower end of a coastal creek to release its young is a genuine estuarine dependence, and it is the same dependence the state points to when it explains why several surfperch dropped out of California landings between the 1930s and the 1990s.

One last note on longevity, because it changes how the fish should be read. Striped seaperch live to about 10 years, tied with the rubberlip seaperch for the longest life span in the family. A 15-inch striped seaperch on a reef is not a fast-growing fish that appeared last season. It is an animal most of a decade old, which has given birth several times, and which took years to reach the size that makes it worth a second look.
