Juveniles remain in <br />freshwater for 2-3 years before returning to the <br />ocean. Spawn in gravelly substrate in cool, clear, <br />well-oxygenated streams in flowing water, usually at <br />the tail of a pool or at the riffle at the head of a pool. <br />No suitable habitat <br />present Presumed absent <br />longfin smelt <br />(Spirinchus thaleichthys) C/T/- Resident <br />Range extends from the Gulf of Alaska, south to the <br />Sacramento-San Joaquin estuary. Some populations <br />are anadromous and migrate up rivers to spawn. <br />Habitat includes range of temp and salinity <br />conditions in coastal waters near shore, bays, <br />estuaries, rivers, and some landlocked lakes. <br />Spawning occurs in fresh water, over sandy-gravel <br />substrate, rocks, and aquatic plants <br />No suitable habitat <br />present Presumed absent
