The rainbow smelt (Osmerus mordax) is a small schooling fish that is native to watersheds of the northwest Atlantic ocean. They are anadromous (ie. adults live in saltwater, migrating to freshwater to spawn), however some populations live permanently in lakes due to human introduction (ex. The Great Lakes). Rainbow smelt are predatory, consuming mainly zooplankton and even young fishes. They live for 5-6 years and survive in various environments, including waters from -1.8ºC to 20ºC!
