Salmonid production refers to the growth and survival of salmon, especially juveniles.
The figure at bottom left is a conceptual diagram showing the factors contributing to the productive capacity of wild subyearling salmon in the the Columbia River estuary (Simenstad 2001).
The figure at bottom right shows that salmon performance within the estuary is directly linked to population structure upriver, habitat opportunity, and habitat capacity.
Hatchery releases, salmon harvest, and watershed modifications alter population structure and also may affect patterns of salmon rearing and migration in the estuary (Bottom et al. 2001).
Processes that affect salmonid production:
- Food web support
- Primary production
- Successional development
