Taxonomy

Rarity

Redtail surfperch is a northern fish, and that is the first thing to know about it. State catch records put 99 percent of the California take north of Point Conception and 1 percent south, and the range itself stops in central California. The state says so twice, once in its range table, which ends the species at Avila Beach in San Luis Obispo County, and once in plain prose noting that redtail surfperch are not known to occur south of Point Arguello. It is also the only marine surfperch in California whose range does not reach into Baja California, and the only one classified as a temperate rather than a subtropical species. This page exists because the site covers the Pacific Northwest and northern California, where the redtail is one of the principal fish in the surf.

Within that range it is abundant and heavily fished. The recreational catch averages 67,000 fish a year, among the 7 most caught surfperch statewide, and 54 percent of all commercially landed surfperch identified to species in the 1990s were redtails, the largest share of any member of the family. The commercial fishery is centered on the Crescent City and Eureka coast.

The trend numbers are the worst in the family. Between the survey periods of 1981 to 1989 and 1993 to 2001, the average annual redtail catch fell 78 percent and the catch per 1000 angler hours fell 84 percent. No other California surfperch lost that much of its catch rate. The IUCN has never assessed the species, so there is no global category to set against those figures.

The regulation is unique to this fish. Redtail surfperch is the only California surfperch with a minimum size, at 10 and a half inches total length, established in 2002. It also sits inside the ordinary family aggregate of 20 fish per day with no more than 10 of any 1 species. Commercial take is prohibited south of Point Arguello, which is a rule with nothing to do, since the fish is not there.

Location

Redtail surfperch range from Vancouver Island down to Avila Beach, and they belong to the surf zone biome for most of the year. This is an open-coast animal, holding in the wash and the trough on exposed sand beaches, in water almost always shallower than 25 feet. The outer recorded depth is about 60 feet, and it is not where the fish are. They also work the bay biome and, less often, the rocky reef biome where a jetty or a rocky shore puts hard structure against sand.

The bay part of that is seasonal and it is worth planning around. Redtail surfperch spend most of the year in the open ocean and then move into sheltered estuaries and bays in spring and early summer, just ahead of the birthing season. When they do, hundreds of fish can concentrate into a small area, which is why anglers who know the timing fill a limit easily. The state records the same movement from its own side, listing estuaries and bays among the main habitats and giving the birth season as spring through early fall, the longest release window of any California surfperch.

Identification runs into the calico surfperch, and the confusion goes both ways. Redtail surfperch are silvery with a light brassy cast and a green tint on the back, and along the rear half of the sides run 9 to 11 narrow dark vertical bars, broken and staggered where they cross the lateral line. The tail and anal fins are red, and the tail can run from pink to nearly purple, which is where the common name comes from. The 2 reliable checks against a calico are shape and dorsal fin. A redtail is the more elongate fish; a calico is rounder and more disc-like. On a redtail, the longest dorsal spines are clearly longer than the soft rays behind them, while on a calico the 2 are about equal.

The diet is broader than most of the family. Redtail surfperch eat marine worms, crabs and other small crustaceans, and also small fish, which is unusual among surfperch and matches the size of the animal.

Spearfishing Brief

No dedicated account of spearing redtail surfperch exists in print. The ratings here come from the documented habits of the fish and from where the other 2 sand-beach surfperch sit in this Ichthyopedia.

Finding one rates a 2, which is the easiest of the surf-zone trio. Within its range the redtail is not the second fish on the beach the way a calico is in southern California. It is the dominant surfperch on open northern sand, in water shallower than 25 feet, and for a stretch of spring and early summer it packs into estuaries in numbers that make finding one a non-problem.

The shot rates a 2.5, matching the barred and calico surfperch exactly, because the problem does not change. This is an open-water fish over open sand in moving water. There is nothing to pin it against, no cover for an approach, and the visibility in a working surf zone is usually poor. Overall difficulty is 2.5.

A long pole spear is the tool for the same reason it is on any surf-zone perch, which is reach. At up to 16 inches and 4 pounds this is the biggest of the 3, so a short shore-diving gun is a defensible alternative if that is what a diver carries.

One rule matters more here than anywhere else in the family, and it is worth stating flatly. Redtail surfperch is the only California surfperch with a minimum size, at 10 and a half inches. A speared fish cannot be measured and put back. That makes the size judgment a decision taken before the shot rather than after it, and it is the reason a diver targeting this species needs to be confident about what a legal fish looks like in the water.

At the table the redtail is the best of the surf-zone trio, and the reason is size rather than flavor. The flesh is the family standard, white, mild, low in fat, finely flaked and soft, frying best and grilling and baking well. What separates it is that a 4-pound surfperch produces fillets worth cutting, where the barred and calico produce a token. California anglers who fish all 3 treat them as fine eating and rank them together.

Deep Dive

The redtail surfperch is the clearest case in this family of a fish whose biology and whose fishery point in opposite directions, and California's rulebook is the record of people noticing.

Start with the biology. Surfperch do not lay eggs. Fertilization is internal, the female carries the young to full development, and what is born is a small complete fish that swims immediately. A redtail brood runs from 1 to 45. The species lives to about 9 years. And here is the part that matters: female redtail surfperch do not reach maturity until they are 3 or 4 years old. The state uses this species as its worked example of how age at maturity varies across the family, setting it against relatives whose males are sexually mature at the moment of birth. Against a 9-year life span, a female that cannot reproduce until year 3 or 4 has perhaps 5 or 6 breeding seasons, and produces at most a few dozen young in each.

Now the fishery. Both redtail and barred surfperch are caught primarily from beaches during the birthing season, which for the redtail runs from spring through early fall. Anglers target the larger fish because they are larger, and in this family the larger fish are the females. They also grade the catch, releasing smaller fish once bigger ones come in, which pushes the take even further toward mature females. The state spells this out and notes the obvious consequence, which is a greater removal of exactly the animals a slow-maturing population can least afford to lose.

Put those together and the trend numbers stop being surprising. An 84 percent fall in catch per angler hour across 2 survey periods is a steep line by any standard, and it is steeper than anything else in the family. Catch rates are not a population estimate, and the state is careful to say so, but they are harder to explain away than raw catch, because a drop in raw catch can simply mean fewer people fishing.

California's response in 2002 was the minimum size, and choosing that tool for this species specifically makes sense once the maturity number is in view. A bag limit protects a population by capping how many fish leave the water. A size limit protects it by deciding which fish leave, and a 10 and a half inch floor is an attempt to let a fish breed at least once before it is taken. Whether 10 and a half inches actually corresponds to a 3 or 4 year old female is not something the state chapter establishes, and it is the obvious question to ask of the rule.

There is one more thing about this fish that its northern address explains. Every other marine surfperch in California reaches Baja California. This one stops in central California and is classed as a temperate rather than a subtropical species. That makes the redtail the family's cold-water specialist, the member that went north and stayed there, and it also makes it the member most exposed to a warming coast. The state notes, without elaborating, that some of the decline in surfperch populations has been associated with rising water temperatures. For a fish whose southern boundary already sits at Avila Beach, that is not an abstract observation.
