Farmed salmon in open net cages can escape into wild habitats, for example, during storms.

The purpose of the modifications is to increase the speed at which the fish grows without affecting its ultimate size or other ...
To produce one kilograms of farmed salmon, products from several kilograms of wild fish are fed to them – this can be described as the "fish-in-fish-out" (FIFO) ratio.
