Species profiles are literature summaries of the taxonomy, morphology, distribution, life history, and environmental requirements of coastal aquatic species. They are prepared to assist in environmental impact assessment. The California halibut, Paralichthys californicus, usually lives nearshore at depths for 100 m or less. It spawns at depths of 5 to 18 m spawning is from February to July and peaks in May. Some California halibut may live as long as 30 years. Annual commercial catches 1916-1984 for California ranged from 29 to 779 t. Juvenile halibut feed on zooplankton and small fish adults are almost totally piscivorous. Adults preferred temperatures of 15 to 23 C. Shallow bays and estuaries are probably important nursery grounds for the California halibut. Information about the environmental requirements of the California halibut is scarce. Author
