Osmerus mordax is a fish species belonging to Osmeridae. The distribution is circumpolar and has been introduced to Great Lakes and it made its way to various other places. Trout, walleye and other larger fish prey on these smelt. Their diets prefer juvenile ciscoes and zooplankton such as calanoid copepods and other small organisms but will consume any fish they find. Rainbow smelt are anadromous spring spawners and prefer clean streams with light siltation and light flow. They face various barriers. Being weak swimmers, they could not overcome most fish ladders. It prevents making past dams to headwater streams where they spawn. In 1980s, rise in erosion and dams assist to decimate smelt population. Current plans helps to lower damming and assist in controlling erosion.
These fish are found in Pacific and Atlantic Oceans. It is also called freshwater smelts or typical smelts in order to differentiate rom related Bathylagidae, Argentinidae and Retropinnidae. The smelt species are common in North American Great Lakes and seas or lakes of northern part of Europe where they move in large schools along saltwater coastline during spring migration to spawning streams. In recent decades, smelt populations have declined greatly in some western parts of United States leading to its protection under Endangered Species Act.
