Growth reaction norms of salmon of farmed, hybrid and wild origin. Reaction norms for the log transformed weight measurements of Atlantic salmon of wild , hybrid and farmed origin reared in the control treatment and the stress treatment at week 14 (dotted line) of the experimental period and at termination, week 16 (solid line). Replicated tanks are pooled. The within-tank biomasses were dramatically reduced at week 14, thus the dotted (−−) and the solid (^__) lines display the reaction norm before and after the reduction, respectively.
