Juvenile coho salmon (Oncorhynchus kisutch) responses to salmon carcasses and in-stream wood manipulations during winter and spring
We investigated the growth rate, winter survival, presmolt size, and emigration timing of juvenile coho salmon (Oncorhynchus kisutch) in response to salmon carcasses and in-stream wood.

Sixteen pens with emigration traps were built in a side-channel of the Mamquam River...

متن کاملSeasonal Habitat Use and Early Marine Ecology of Juvenile Pacific Salmon in Southeastern Alaska
Habitat use and early marine ecology of juvenile (age-.O) Pacific salmon (Oncorhynchus spp.) were studied monthly at inshore, strait, and coastal habitats along a seaward migration corridor in southeastern Alaska from May through October 1997-99. A total of 31 ,853 fish from 40 taxa were captured with 283 surface trawl hauls; juvenile salmon made up 61 % of the total catch. Predation on juvenil...
