For plotting only, the returns to controls and exposed stocks have been separately summarized by a multiplicative model (log(Returnsi,y) = ai + dy + ei,y ; variables are the same as in Equation 1). The mean returns across stocks for each year are shown. Note that left-hand axes are on a log scale. Only even year values are available for pink salmon prior to 1989. Irish salmon are not included because only marine survivals (not returns) are available.
