What do cormorants eat?

All are fish-eaters, dining on small eels, fish, and even water snakes. They dive from the surface, though many species make a characteristic half-jump as they dive, presumably to give themselves a more streamlined entry into the water. Under water they propel themselves with their feet. Some cormorant species have been observed at depths of over 40 feet. In England and Wales, roach and perch are the most numerous prey items while rainbow and brown trout are consumed at put-and-take trout fisheries. Cormorants commonly take fish between 5 and 15 cm (2 to 6 inches) in length, but have been recorded eating fish of over 40 cm (16 inches) and eels of over 60 cm (24 inches) long.
