Feeding Ecology And Diet

Although lingcod will eat invertebrates such as crabs, shrimps, and octopi, they mainly feed on other fishes, including younger lingcod. A lingcod engulfs another fish headfirst. The throat rapidly opens while the mouth engulfs the prey, so that a fish about two-thirds the length of the lingcod will be swallowed immediately into the entire length of the stomach, with only the tail protruding from the mouth. During years of abundant prey, growth is rapid. After two years lingcod of both sexes tend to reach about 1.5 ft (46 cm) in length, after which males grow more slowly than females, perhaps owing to the seasonal feeding migration that only females undertake.
