Taxonomy

Rarity

The spotfin croaker is not a threatened species. The IUCN Red List assessed the species as Least Concern in 2020, with a population described as stable and widely distributed. On a shore dive, though, it is not an everyday encounter. Adults live in small groups of usually fewer than 50 fish and move considerably between bays without a discernible pattern. A limited tagging program run by the California Department of Fish and Game recaptured Los Angeles Harbor fish as far south as Oceanside in San Diego County. What the diver sees on a given day depends on whether the fish have moved through, and on whether the diver is over the right sand pocket in the right season. A spot that held 4 fish in July can be empty by August with no warning. The pressure on the population is not the fishery. Commercial take of spotfin croaker has been illegal in California for more than a century, first by a net ban in 1909 and then by a total sale ban in 1915. The current concern is coastal development, dredging, and land fill inside the bay and nearshore habitats the species depends on.

Location

Spotfin croaker range along the eastern Pacific from Point Conception in Santa Barbara County, California, south to Mazatlan in Sinaloa, Mexico, including the Gulf of California. The center of the population is southern. The fish are most abundant south of Los Angeles Harbor and become scarce north of Point Conception. They are demersal, meaning they live and feed on the bottom, and they are strong soft-bottom specialists. A 2012 Southern California Bight study by Williams and colleagues captured 16,756 spotfin croakers by gill net and found catch rates roughly 35 times higher over sand and mud than over rocky bottom. Adults hold on sandy and muddy substrate along open beaches and inside bays, most often in 4 to 30 feet of water and down to about 50 feet. Within that broader zone they concentrate in depressions and holes near shore, which surf anglers call croaker holes. Rocky reef is not their habitat, though they will edge onto rock in warmer water. Spawning happens offshore from June through September. Ripe fish have almost never been caught in the surf zone, so the eggs and larvae are released well outside the beach zone. Small juveniles 2 to 4 inches long then move back into the surf and the shallow sandy flats in the fall, where they grow before joining the adults.

Spearfishing Brief

Spearing spotfin croaker is a surf-zone specialty, and finding the fish is the harder half of the hunt. The fish is not camouflaged. Its silvery flank and the black spot at the base of the pectoral fin make an obvious target on a clean-water day. The trouble is the distribution. Adults hold in small groups on specific pockets of sand. They favor the depressions surf anglers call croaker holes. They also move between bays with no pattern a diver can predict. A diver over featureless flat sand outside the season may swim the whole dive and see nothing. Sight-fishers on a productive stretch of summer surf have counted up to 6 spotfin in a single wash. Finding the fish rates a 3 for difficulty and the shot rates a 2, so the overall rating of 3 comes from the search. Because the season is compressed and the productive water is often the shore break, the last hours of light on a clean-water day are the useful window, and a low or falling tide is when the larger fish are reported. Southern California surf routinely puts sand in the water, so a diver hunting spotfin picks the day, not the schedule.

Once found in the shallows, the fish is approachable. Surf-fishing observers document adults getting so absorbed in rooting up sand crabs that their tails break the surface as they feed. Fish that are this focused on feeding tolerate a close approach. The shot is taken at close range over 3 to 15 feet of water, on sand just behind the first line of breakers or inside a bay flat at slack tide. Sources specific to spearing this species are thin. The surf-zone accounts describe a polespear, which suits water this shallow, and no spearfishing writeup establishes a speargun size for the species. A longer gun is no help on a fish that has to be shot at close range, and it tangles more in the surge. When shore diving through a shore break, a speargun with a reel is preferred over a floatline, because a floatline tangles in the surf zone on the way through.

Spotfin croaker is also one of the prized rod-and-reel targets in the Southern California surf. Pier, jetty, and surf anglers fish the same croaker holes at the same time of year, throwing sand crabs, ghost shrimp, or fresh mussel meat on the bottom. Dusk is the peak time for that fishery too, with one long-running surf-fishing log reporting more than 80 percent of hooked spotfin taken right around sunset. A diver hunting a Southern California beach in July is hunting the same fish the anglers overhead are casting for.

Deep Dive

The spotfin croaker belongs to the drum and croaker family, a mostly warm-water group whose defining feature is the drumming sound the fish produce. In the family generally, a specialized muscle vibrates against the swim bladder, the gas-filled organ a fish uses to control its depth, which acts as a resonator and amplifies the sound. Drums and croakers use these calls in spawning behavior, and many species in the family gather in offshore spawning aggregations. The specific role of vocalization in spotfin croaker biology has not been closely studied. What is documented is that the fish spawn offshore in a strongly sex-segregated pattern. At an offshore sandy spawning site sampled by Williams and colleagues from 2001 to 2003, 92 percent of the spotfin croakers caught by gill net were male. At protected bay sites over the same period, 60 to 79 percent were female. Male and female fish sort themselves between habitats during the spawn, and anglers or divers who search just one habitat are only reaching one half of the population.

Growth is sexually dimorphic. Through age 3, males and females grow at similar rates. After age 6, females average 1.2 to 2 inches larger than males of the same age. Sexual maturity comes early. Most males mature at about 9 inches and 2 years old, most females at about 12.5 inches and 3 years old, and every fish is mature by 14.5 inches and 4 years. Spotfin croaker can reach 27 inches and 14 pounds. The California angling record of 14 pounds still stands from a fish taken at Playa del Rey in Los Angeles County in 1951. The current all-tackle world record kept by the International Game Fish Association is smaller, at 9 pounds 14 ounces from Baja California in July 2012. The oldest fish yet aged, at 24 years, came from the Williams study, which aged its fish from cross-sections of the ear bones. That figure was 14 years greater than the maximum age from an earlier study that had counted scales. The scale method appears to under-count the older fish.

Spawning coloration is a useful field mark. During the June through September breeding season, females develop blackish streaks along the belly, and larger males develop golden pectoral and pelvic fins. Male spotfin croakers in this coloration are commonly called golden croaker. There is no documented aggression from spawning fish toward divers or people, on the spawning grounds or elsewhere.

Diet is where the anatomy comes together. Adults are bottom feeders that specialize in hard-shelled prey. Behind the mouth, in the throat, is a thickened plate of teeth called pharyngeal teeth, arranged as a pavement of blunt crushing surfaces. The fish crushes whole clams, mussels, and the small marine bristle worms called polychaetes with those throat teeth and swallows the meat. In the surf zone the diet is heavy on sand crabs, which spotfin follow into ankle-deep water at dusk. Juveniles start on small crustaceans and on the muscular siphons that clams push up through the sand, before growing large enough to crush whole shells. Documented predators of adult croakers in the Southern California nearshore include larger fish such as sharks, rays, California halibut, and barred sand bass, along with California sea lions, harbor seals, and diving cormorants, though a study focused specifically on spotfin predation has not been published.

The commercial-prohibition history is the reason the spotfin croaker fishery still exists in a healthy form. Net take was banned in California in 1909. The sale of the fish anywhere in the state was banned in 1915, and that ban is now codified in Fish and Game Code section 8373, which forbids the sale, purchase, or commercial possession of spotfin croaker, yellowfin croaker, or California corbina. A companion section, 7856, forbids the fish being carried aboard a commercial fishing vessel on a commercial trip. Together these mean the spotfin croaker has been a recreational fish and only a recreational fish for over 110 years, longer than most of California's protective fishing rules have existed. The general 10-fish daily bag limit under Title 14 section 27.60 is judged sufficient for sport take without the risk of depleting the stock. The active concern for the population is habitat loss. Comparative beach seine surveys from 1994 through 1997 yielded far fewer spotfin croakers than a matched study from 1953 through 1956, and Williams and colleagues in 2012 explicitly recommend protection and restoration of estuaries and bays as the priority for the species.

On the plate, spotfin croaker is a respectable panfish. The meat is white, flaky, and mild, with a soft texture and a low fat content. Surf anglers rate the eating quality as good, and the California Department of Fish and Game itself describes the taste as delicate in its status report. A single spearfishing forum report describes a leathery texture from a pan-fried fish. That report is the only dissent located, and it is too thin on its own to move the rating. The honest overall stays good rather than excellent. Standard preparations are pan-fried, grilled, baked, broiled, and in fish tacos, with the mild flavor pairing well with lemon, butter, and herbs. Pier Fishing in California recommends baking or broiling over pan-frying because of possible toxins, noting that spotfin croaker shares the pollution problems of the other croaker species and may be unsafe to eat in certain localities. A shore diver on a Southern California beach in July, hunting a croaker hole with a polespear in the shallow sand behind the surf, is hunting a fish Californians have kept off the commercial market for over a century so that the recreational catch stays healthy. The fillet in the pan is white, mild, and clean.
