Chart showing interrelationship factors of other fish productionOther fish production refers to the growth and survival of other (non-salmonid) species of fish and invertebrates (i.e., commercially harvestable species).

The figure at bottom left shows a simplified representation of the major linkages between trophic groups in the estuary (Weitkamp 1994). Arrows indicate direction of energy flow.

  • Processes that affect other fish production:
  • Primary production
  • Food web support
  • Refuge
