when Greenberg mentions salmo domesticus, he essentially means domesticated salmon. so in other words, he means fish that are born and raised in enclosed environments, like hatcheries for instance. according to my readings, domesticated salmon originated when small tribes caught salmon and attempted to breed them in enclosed environments so they were able to have easier acess to their resources without having to fish for them. it then began to grow at a larger, more economic scale, then Norway began to catch on and to this day is still one of the worlds larges salmon producing countries.
alot of people think that salmo domesticus are a curse, but i personally consider it a blessing. although it is true that “domesticated salmon” arent exactly wild salmon and there are some negative effects to having salmo domesticus in the wild, but i belive the positive effects far outweigh the negative. if salmon are grown in controlled environments, they can become much larger and provide more nutrients to many communities, so if salmo domesticus become a major part of many peoples daily lives, they will be able to feed many more people over time.
