Norwegian here. I live not that far from some fish farms (Mowi), and the wild fish around the farms are also inedible. Large fat bodies that taste weird. Most

    Is a fact that marine cages boost biodiversity or, being more precise, alter biodiversity. There are clear visible benefits on the fish schools and damages on the bottom invertebrate communities. I had seen tuna cages at the sea ant there are small breams everywhere under the cage. Young fishes used their surrounding areas as a sort of sanctuaries with plenty of food scraps and no fishing. The cage acts as a protecting physical structure that big predators avoid to no get entangled. Wild fishes living near salmon cages learn soon also that in this places it rains tasty fatty food every few days at exactly the same hour. The cons is that the overlooked pellets falling in the bottom attract invertebrates able to stand the pollution that multiply exponentially and conquer the whole community.

    > Curious, is there any theory what mechanism is behind this? They eat the food that falls through the net, and the food is designed. To maximize growth. It also includes artificial colour, the farmed salmon really has white flesh. This colour also affects the fish living beneath the fish farm.
