Reproductive performance of alternative male phenotypes of growth hormone transgenic Atlantic salmon ( Salmo salar )
Abstract Growth hormone (GH) transgenic Atlantic salmon ( Salmo salar ) is one of the first transgenic animals being considered for commercial farming, yet ecological and genetic concerns remain should they enter the wild and interact reproductively with wild fish. Here, we provide the first empiric...
