Smelts are a family of small fish, the Osmeridae, found in the Atlantic and Pacific Oceans. They are also known as freshwater smelts or typical smelts to distinguish them from the related Argentinidae, Bathylagidae, and Retropinnidae.
Some smelt species are common in the North American Great Lakes, and in the lakes and seas of the northern part of Europe, where they run in large schools along the saltwater coastline during spring migration to their spawning streams. In some western parts of the United States, smelt populations have greatly declined in recent decades, leading to their protection under the Endangered Species Act. The Delta smelt, Hypomesus transpacificus, found in the Sacramento Delta of California, and the Columbia River smelt, Eulachon, are both protected from harvest.
Some species of smelts are among the few fish that sportsmen have been allowed to net, using hand-held dip nets, either along the coastline or in streams. Some sportsmen also ice fish for smelt. They are often fried and eaten whole.
In size, smelts usually grow to about 20 cm (7.9 in) long, although some species can reach 70 cm (28 in). Smelts are a food source for many fish, including salmon, striped bass, and lake trout.
