The silver trout (Salvelinus agassizii) is an extinct char species or variety that inhabited a few waters in New Hampshire prior to 1939, when a biological survey conducted on the Connecticut watershed by the New Hampshire Fish and Game Department found none. Salvelinus agassizii (Silver Trout) is a species of bony fishes in the family Salmonidae. A salmonid fish and hence closely related to salmon and trout, the Blackfin Cisco was once plentiful in the Great Lakes, but recently succumbed to a combination of overfishing and predation by not one, but three, invasive species: the Alewife, the Rainbow Smelt, and a genus of sea lamprey. (2015). To formally describe the species and prevent local fishermen from overharvesting in the absence of bag limits, specimens were sent to Harvard and the U.S. National Museum for identification, where the fish was first described as a form of lake trout (Salvelinus namaycush), and later as a variety of brook trout (Salvelinus fontinalis).

, The silver trout was an exceedingly rare fish, having become trapped by changed drainage systems in two New Hampshire lakes (Dublin/Monadnock Pond and Christine Lake in Stark) that were left as successors of Lake Hitchcock, a very large glacial lake that persisted for 4000 years where the silver trout probably evolved from brook trout. , By the late 19th century, as each lake developed its own steady summer tourism, recreational fishermen who sought to increase their catches began to introduce new fish species, and these eventually overwhelmed the native silver trout.
