Habitat
Pacific redfin primarily inhabit clear, cold rivers, streams, and coastal waters in the Northwest Pacific, including regions like Japan, Korea, and Russia. They prefer fast-flowing waters with gravel or rocky substrates and can tolerate slightly brackish environments near river mouths. This species is adaptable but thrives in areas with ample oxygen and cover from vegetation or rocks.
Diet
Pacific redfin are omnivorous, feeding on small aquatic insects, crustaceans, algae, and plant matter. They exhibit opportunistic feeding behavior, often foraging near the bottom or in mid-water during daylight hours. Their diet varies seasonally, with a higher intake of insects in summer and more plant material in other times.
Behavior
Pacific redfin are schooling fish that form loose groups for protection and feeding, especially in open waters. They are diurnal, active during the day, and may become territorial during spawning when they defend gravel beds. This species exhibits migratory behavior, moving upstream in rivers to spawn and returning to lower areas afterward.
Conservation Status
Listed as Not Evaluated by IUCN.
