How to recognise it
The California Halibut (Paralichthys californicus) is a flatfish with a distinctive shape. It has a flattened body that allows it to lie on the ocean floor. The coloration is typically brown or olive on the upper side, with lighter shades on the underside. The fish can reach lengths of up to 40 inches and weigh as much as 50 pounds. Its dorsal fin runs along the length of its body, while the anal fin mirrors it on the underside. The mouth is large, filled with sharp teeth. The California Halibut is often confused with the Pacific Halibut (Hippoglossus stenolepis). The key detail that separates them is the number of gill rakers; California Halibut has 20 to 25, while Pacific Halibut has 30 to 40.
Where it lives
California Halibut are found along the Pacific Coast of the United States, from San Francisco Bay in California to Baja California in Mexico. They inhabit coastal waters, typically in sandy or muddy bottoms. The depth range for this species is generally between 10 to 300 feet. During the warmer months, they tend to move into shallower waters, while in colder months, they may migrate to deeper areas. They often seek cover near structures such as reefs, kelp beds, and piers, which provide protection and hunting grounds.
When it bites
California Halibut are most active from late spring through early fall, particularly from May to October. The ideal water temperature for fishing is between 60°F and 75°F. They tend to bite more aggressively during the early morning and late afternoon. Environmental factors can influence their feeding behavior. A passing front may trigger increased activity, while strong winds can make them less likely to bite. A full moon can also enhance feeding opportunities, as the increased light encourages them to hunt.
How to catch it
To catch California Halibut, anglers often use a variety of rigs. The sliding sinker rig is popular, using a 1 to 4-ounce sinker depending on the current. Baits such as live anchovies, sardines, or squid are effective, typically in sizes ranging from 4 to 6 inches. Lures like swimbaits or jigs in natural colors (white, brown, or green) can also be productive. Use a 20 to 30-pound test line with a 2/0 to 4/0 hook. Cast near structures or along sandy bottoms, and work the bait with a slow, steady retrieve, allowing it to bounce along the sea floor.
Size, age and the table
Anglers typically encounter California Halibut ranging from 20 to 30 inches. A trophy fish is generally considered to be over 40 inches. Growth rates vary, but they can reach maturity at around 3 to 5 years of age. The lifespan of California Halibut can extend up to 15 years. They are known for their excellent eating quality, with firm, white flesh. When handling, it is important to keep them wet and minimize stress. If releasing, do so gently to ensure their survival.
