Cutthroat Trout
Oncorhynchus clarkii
A native coastal trout that hunts fry and shrimp in estuaries, beaches and small rivers. Sea-run cutthroat follow the tide, ambush baitfish along shore, and rise eagerly to flies and small spinners.
Seasons · Peak
Identifying features
- Distinctive red to orange slash marks under the lower jaw — present on every cutthroat
- Fine black spots concentrated toward the tail, sparse near the head
- Olive to brassy sides; sea-run fish are silvery with a faint yellow wash
- Teeth on the back of the tongue (hyoid teeth), unlike rainbow trout
- Look-alike: rainbow trout have no jaw slash and show spots evenly over the whole body and tail
Habits
- Ambush predators that cruise shorelines hunting fry, shrimp and sculpins
- Follow the flooding tide onto estuary flats, drop back as it ebbs
- Usually alone or in loose small groups, not tight schools
- Feed through the day in low light; shaded banks fish best
Distribution
Where to find them
- Creek mouths and oyster or gravel beaches in estuaries
- Undercut banks and overhanging trees on small rivers
- Lake inlet mouths and shallow shoals in spring
