Dear SARA,
Thank you for your work.
I would be very interested to know the ocean feeding locations for each group of salmon. St. John strains may gather in somewhat different locations than say York River fish while spending time at sea.
The North Atlantic Oscillation (Read This From U Mass) records going back for many years show a warming trend for the North Atlantic and in different locations spikes in temperature may occur as a result of ocean currents.
Should the location of post smolt ocean feeding take place in a spike zone then the cold water food source is limited and the run for that region reduced.
Until a study can be created to determine the ocean feeding locations by river strain, it is my opinion we will never get to the answer. Doing all the work that is close at hand like land environment and river condition will not offer the cold water food necessary to avoid loss to critical mass.
William
