Salmo domesticus in my understanding is domesticated salmon. This means it was made to grow fast and in a controlled environment. When I very first learned about farmed fish is was not good . I was told that they put growth hormones and dyes into the fish to make them look more appealing so they can be sold more easily. When reading from what Greenburg says about the farmed fish I believe that they are detrimental to the environment. From the book it states that to get one pound of farmed fish there would need to be six pounds of wild fish. These fish are ground up into pellets for the farmed fish to eat. (P.g. 44) This is very harmful to the environment causing a deficit in the wild populations. Not only do these farmed fish need food they need a space to grow. These farms are large and can harm the environment also. There is waste and chemicals that are released from these farms harming the ecosystem around them. In my own opinion I believe that farmed fish are harming our fish populations and ecosystem.
