Data from: Can variation in standard metabolic rate explain context-dependent performance of farmed salmon offspring?
Escaped farmed Atlantic salmon interbreed with wild Atlantic salmon, leaving offspring that often have lower success in nature than pure wild salmon. On top of this, presence of farmed salmon descendants can impair production of wild type recruits. We hypothesize that both these effects connect with...

Escaped farmed Atlantic salmon interbreed with wild Atlantic salmon, leaving offspring that often have lower success in nature than pure wild salmon.
