Stenodus nelma is an anadromous fish, up to 150 centimetres (59 in) in length. The fish has a large mouth with a protruding lower jaw and a high and pointed dorsal fin. It is generally silver in color with a green, blue or brown back. The meat is white, flaky and somewhat oily. An adult fish weighs up to 27 kilograms (60 lb). The fish eat plankton for their first year of life and then become predators of smaller fish. They live in lakes and rivers and in the brackish water at the outlets of rivers into the ocean. They may migrate more than 1,600 kilometres (1,000 mi) to their upriver spawning grounds, but some populations spend their entire life in fresh water and do not migrate.
