Distinguishing Between Restoration and Aquaculture
An aquaculture model will result in the run returning to the level prior to intervention upon cessation of supplementation.
A restoration model should lead to the condition that terminating human intervention will not result in a return of the salmon run to the levels before intervention.
Notes:
If nutrient additions are a form of aquaculture, then a wastewater discharge permit would be required and treatment or removal of wastes required.
