Salmo domesticus is a breed of salmon somewhat like the others but not quite. This type of salmon had different qualities on the inside because it is a farmed fish. Salmo domesticus turned out to be one of the most successful salmon in the world because the Norwegians ability to turn a fish farm unit into an international way of fish farming around the world. Tons of farmed fish were being harvested at the time, the waters were filled with cages and farmed fish were being shipped all over. I think Salmo domesticus evolved because we (as fishermen and humans in general) were not patient enough to work with the resources that we had so we created another resource to substitute the lack of wild salmon that we are causing to go extinct in the first place. Salmo domesticus can be both beneficial and detrimental in many ways. For example, on the beneficial side, creating a new species of salmon can provide more food for people who eat it as long as we are not hurting the environment that our wild salmon live in. But compensating the weight of losing our wild salmon with farmed fish is not going to help repair the damage that is already caused. Farmed salmon do not benefit the ecosystem the same way a wild salmon does.
Paul Greenberg also mentions some of the process that goes into farming salmon, “-farmed salmon require as much as six pounds of wild fish,” (Four Fish Greenberg, pg.43). If we are going to create a species of fish that we can eat but feed it our own food that we should be eating, why are we farming salmon? It reminds me of the question asked by Arthur McEvoy today in class, “What ought we sustain?” Why don’t we sustain the environment that we have already?
