Taxonomy

Rarity

The copper rockfish is a common resident of the shallow rocky Pacific Northwest coast and one of the more restricted rockfish in the region for legal take. The IUCN Red List assessed the species as Near Threatened in February 2024 under criteria that flag population declines from historic fishing, though the current global trend is listed as increasing. The picture varies sharply by area. On the outer coast of Oregon, the fish is a routine catch. In Washington's Puget Sound, the population is classified as a Species of Greatest Conservation Need under the state's Wildlife Action Plan, and recreational retention is prohibited across Marine Areas 6 through 13. On the outer Washington coast, possession is closed in May, June, and July. In California, the fish is a 1-fish sub-limit inside the general 10-fish rockfish bag. The species was considered for federal Endangered Species Act listing in 2001 and determined not to warrant listing at that time. Rebuilding is ongoing.

Location

Copper rockfish live along the northeast Pacific coast, from the Kenai Peninsula in the Gulf of Alaska south to central Baja California in Mexico. They range from the subtidal zone down to about 600 feet, but most fish a diver encounters hold on shallow, high-relief rocky bottom, kelp beds, or hard artificial structure (pilings, jetties, wharfs). Adults hold close to the bottom, often touching it, and are almost always associated with rock. They are rarely found on open sand. Juveniles use different habitat than the adults, aggregating in shallow weedy bays, around wharfs, and among floating drift, before shifting to reef as they grow.

Adults are typically solitary or in small groups, and they are highly site-attached. Tagging studies show that a copper rockfish rarely travels more than a mile from its chosen home range, and a well-known ledge or pinnacle tends to hold the same fish year after year. The color runs from dark reddish-brown with pale copper blotches in northern populations to a lighter yellow-olive in the south, with a distinctive clear patch along the rear half of the lateral line and tall, strong dorsal fin spines. Coloration overlaps with the closely related quillback and brown rockfish, and in Puget Sound the 3 species are known to hybridize, which is one reason the WDFW recommends assuming any suspect fish is protected and releasing it.

Spearfishing Brief

The copper rockfish is a well-regarded target for divers on the outer Pacific Northwest coast, and its difficulty is a 2 on both axes. Finding one takes more searching than a black rockfish because copper rockfish do not school and they hold tight to specific rocks. Where a black rockfish is a cloud of fish in the water column, a copper rockfish is a single fish or a small group tucked against the base of a boulder or under a ledge. A diver who knows a stretch of rocky bottom, and who searches boulders, ledges, and jetty pilings carefully, will find the same fish on the same structure trip after trip. Their strong site fidelity is what makes them findable, and it is also what makes them vulnerable if a diver takes every fish off a favorite ledge.

The shot rates a 2. Copper rockfish are not particularly wary in low-diver-pressure Pacific Northwest waters. A slow approach through the water column lets a diver settle into position and pick a broadside shot behind the gill plate. Community accounts converge on a short to mid-length speargun of 75 to 100 centimeters with a standard flopper tip. Larger open-water guns offer no advantage in tight rocky terrain and are slow to reload. The fish is also a common rod-and-reel target on rubber-tail jigs fished slowly along the same rocky bottom.

The location where a diver may legally take a copper rockfish matters as much as the shot itself. Puget Sound is closed to copper rockfish retention entirely. The outer Washington coast is closed to copper rockfish possession from May through July. California allows only 1 fish per person per day. Oregon is the most permissive of the 3 states, with copper rockfish falling inside the general 4-fish marine species bag limit without a species-specific sub-limit. A diver targeting copper rockfish across a multi-state trip needs to know the local rule for the exact Marine Area they are in, not the rule from the state next door.

Deep Dive

The copper rockfish belongs to the rockfish family, the same family as the black rockfish, and it shares the family's extreme longevity. Individuals can live past 40 years, and the oldest recorded fish reached 57 years. Growth is correspondingly slow. Males mature between 3 and 7 years, females between 4 and 8. Maximum length is about 26 inches and maximum weight about 10 pounds. A typical adult on the reef is 12 to 20 inches. The name comes from the copper-colored blotches on many northern-population fish, though coloration varies enormously across the range.

Diet in adults is a mix of larger crustaceans, squid and octopus, and smaller fish, with some open-water prey taken when the fish rises off the bottom. Juveniles feed on tiny drifting crustaceans in the shallow-water nursery habitat before moving out to the reef. Documented predators of copper rockfish include lingcod, larger predatory fish on the reef, seals, sea lions, and diving seabirds when the fish is small or in shallow water.

Reproduction follows the rockfish pattern: internal fertilization in the fall, a gestation period of about 10 months, and live release of larvae in the winter that drift as plankton in open water for several months before settling to the reef as juveniles. Larger females carry more young than smaller ones, and the fecundity studies used in the federal stock assessments put the output of a large female in the hundreds of thousands of eggs per season, approaching 1 million only in the very largest fish. What is not in dispute is that a copper rockfish takes years to reach a size worth harvesting and does not replace itself quickly if it is removed from a small home range. That biology, more than any single fishing event, is what shaped the current mix of state rules.

The strong site fidelity is central to the fishery's shape. Copper rockfish do not roam. A pinnacle, a jetty, or a boulder cluster tends to hold a stable resident group year after year, and once a spot is emptied of adults, it is slow to refill. The Puget Sound closure exists in large part because sound populations, cut off from the outer coast by long straits and heavy shipping traffic, cannot easily be repopulated from outside. The outer-coast May-through-July possession closure in Washington and the 1-fish sub-limit in California are calibrated to keep annual take under a level that the slow reproductive rate can sustain.

On the plate the copper rockfish is a first-tier white-fleshed fish, valued in the same class as its rockfish cousins for firm, mild, white meat that holds up to almost any cooking method. Bleeding a shot fish at the boat improves both the color and the taste of the fillet. A single legal copper rockfish, folded into fish tacos or fried into fish and chips, is usually plenty for a meal for 2.
