Smelts are a family of small fish, the Osmeridae, found in the North Atlantic and North Pacific Oceans, as well as rivers, streams and lakes in Europe, North America and Northeast Asia. They are also known as freshwater smelts or typical smelts to distinguish them from the related Argentinidae (herring smelts or argentines), Bathylagidae (deep-sea smelts), and Retropinnidae (Australian and New Zealand smelts). 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 eulachon (Thaleichthys pacificus) found in the Northeast Pacific and adjacent rivers, 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. Description In size, smelts usually grow to about long, although some species can reach . Smelts are a food source for many fish, including salmon, striped bass, and lake trout. Like salmon, many species are anadromous, living most of their lives in the sea, but traveling into fresh water to breed. However, a few exceptions, such as the surf smelt, spend their entire lives at sea. Smelt dipping In the Canadian provinces and U.S. states around the Great Lakes, "smelt dipping" is a common group sport in the early spring and when stream waters reach around . Fish are spotted using a flashlight or headlamp and scooped out of the water using a dip net made of nylon or metal mesh. The smelt are cleaned by removing the head and the entrails. Fins, scales, and bones of all but the largest of smelts are cooked without removal. On the Maine coast, smelts were also a sign of spring, with the run of these small fish up tiny tidal estuaries. Many of these streams were narrow enough for a person to straddle and get a good catch of smelts by dipping a bucket. As food North America Smelts are an important winter
