It's the same issue as "normal" poultry vs "aviary" poultry.
I personally prefer to eat less fish and meat than eating animals that are bred and raised in awful conditions that optimize for revenue; the quality of the output speaks for itself.

Please don't spread fake ideas created for propaganda purposes without a minimum of critical thinking. This is false.
Maybe you aren't aware of this, but the water in marine aquaculture tanks is replaced constantly by fresh, clean water 24 hours a day, 7 days a week. If the pumps stop the fishes would die in hours. Not to mention that many, many species of fishes love to school and feel much better when are crowded. Specially when they are young.
Some fishes just do not care about being kept in water of lower quality. Carps for example work tirelessly to mudd its tank stirring sediments from the bottom. Are brain-wired to do this. Aquaculture of marine fishes is a totally different world than Pangasius or Tilapia aquaculture.
