I disagree that salmon are just as unsuitable as sea bass for aquaculture. No fish will be a perfect candidate, but, that being said, some are definitely better than others. For example, salmon have a much higher survival rate than sea bass. 15-30% of 7,500 is way better than 1 or 2 individuals out of a million. I will agree that no fish really likes human company, probably because they don’t have the mental capacity to form bonds like we see in other mammal species. As for comfort-loving, the salmon definitely don’t try to kill themselves in captivity to the extent that sea bass do. For reproduction, salmon are more likely to reproduce as well, but we don’t exactly need them to either due to the genetic modifications we now have. Sea bass completely shut down when put in a tank.
