Over-winter Survival Studies

Released as 65-80mm late summer Parr; 3 year evaluation.
Is it cost effective? Saves hatchery money and space.
Is there an element of wildness introduced into the surviving spring migrants? Example: will the over-winter parr exhibit SAR rates similar to our NOR coho or our HOR coho??
Which ponds/side channels offer the highest survival?
Results of this may ultimately lead to some over-winter acclimation.
