One of the advantages to salmon farming is that it can be installed almost anywhere
Produces high yields despite small volume of water. Contains Essential nutrients, with a high protein value and low to moderate fat in comparison to terrestrial animals.
Cons
bad disease can be spread as well as unwanted visitors such as sea lice
Beta Carotene is added to farmed salmon to give it color and people say that this is a harmful chemical.
Environmentally people say that farmed salmon escape, or they swim in their own feces or have lice and disease that run rampant in the holding pen.
My Opinion
in my opinion i think salmon farming is not good for very many things and is more harmful for the environment.
