The ecology associated with spawning salmon needs to be understood in greater detail.
What characteristics distinguish starved from healthy from over-enriched photosynthetic and invertebrate communities.
Develop criteria for when nutrient (or calorie) additions are required and when corrective actions to reduce nutrient inputs are needed which reflect conditions in the watershed, not just the observation that the spawning runs are depleted.
Notes:
Ecology NEEDS this input – we don’t have nutrient criteria. Only when nutrient levels adversely impact d.o. or pH does Ecology take action. Ecology has no mechanism to promote nutrient addition to truly deprived systems in the absence of a criterion.
