| DISTRIBUTION
- Coho use all accessible reaches of streams.
- Seasonally wetted areas and off-channel sloughs, swamps and their tributaries are used
for winter rearing.
- In main stems of large rivers, coho use margins, debris piles and under cut banks.
- Coho may be found in frest/saltwater pools in small estuaries.
- In small streams they prefer pools and glides.
|
| BEHAVIOUR
- Coho feed actively on anything falling into water. They are common along stream
margins. Coho are the most common and easily seen salmon fry during the active
growing season.
- Below about 6°C, the fry will seek cover under banks or in debris piles.
- Coho will nip and chase each other.
|
| FRESHWATER RESIDENCE TIME
- Coho remain in fresh water 1-2 years.
|
| OTHER
- Coho are very widely distributed in streams of all sizes, including very small first and
second order streams.
- Some stocks in small first and second order streams may not be in DFO files.
- You may encounter "Lake Forms" of coho with a less sickle-shaped anal fin.
- As coho become ready to smolt, they become brighter and the anal fin is less
sickle-shaped.
