The fry may sometimes feed on nymphal and larval insects, or none at all while in freshwater. Logging an area around a stream reduces the shade and nutrients available to the stream and increases the amount of silt or dirt in the water, which can choke out developing eggs. The eggs hatch from December to February, depending on water temperature, and the juveniles emerge from the gravel during March and April and quickly migrate downstream to estuaries, at about one-quarter gram in weight. In Alaska and British Columbia, they are considered secure.
