    Fish farming is especially bad for diseases and parasites. The densities of fish farms are truly insane leading to high rates of disease, waste accumulation, very high fish mortality rates, etc.

      personally i think fish farming is cost effective, from a protein mass/farming cost ratio standpoint. If big fish benefits the same subsidies as big red meat does, fish farming would be more sustainable and a farmer could use a less denser farm to minimize disease risk, also it would enable him to buy more medicine to fight parasites while maintaining a healthy margin

          The only really sustainable aquaculture products are bivalves and seaweed: https://www.nature.com/articles/s41586-021-03889-2

          interesting: yea better cut out the middlemen and go straight for the nutrient sources. I am not really informed about the subject but farming fish still seem way less harmful than farming methane emitting cows and mrsa ridden poultry. so bivalves and seaweed it is !
