Distribution
Distributed in the northeastern Pacific Ocean.
Habitat
Adults live in waters above rocky reefs, but are also found in deeper waters. Young Bocaccio live in shallow waters and form flocks; they are caught more often than adults, especially in rocky areas.
Size
Bocaccio can grow up to 3 feet and 21 pounds and can live up to 30 years.
Life history and Behavior
Bocaccio that are 1 or 2 years old move in loose shoals and go to shallow waters, where they are caught in large numbers. As they get older, they seek deeper water and move from the surface to the bottom. Adults are usually found in waters between 250 and 750 feet deep above a somewhat rough, hard or rubble bottom. They are known to inhabit depths of up to 1,050 feet. Females begin to mature when they reach 17 inches in length.
Food and feeding habits
Bocaccio feed mainly on fish, including its kind. Their diet consists of mackerel, sable fish, anchovies, sardines, deep-sea fin fish and sand fish, as well as squid, octopus, crabs.
Reproduction
Live-bearing fish. Fertilization is internal and occurs in different parts of the range in different seasons. The sperm remains inside the female for several months before the eggs are fertilized. Hatching occurs within the female. Fertility ranges from 200,000 to 2,300,000 eggs. In some regions, the female may hatch some batches of larvae per season. Hatching occurs during different seasons of the year: British Columbia, February; Washington, January to April; Oregon, January to February; northern and central California, January to March or November to March; southern California, October to March.
