Problem is the farmed fish are fed on wild fish, so it's several times less efficient than just eating whatever you would have fed them.

Some farmed fish (like tilapia) can live on a variety of things, including soy and corn pellets. Algae, which can be used for many things - human consumption, farmed animal/fish feed and even fuel - can also be farmed sustainably. I think we urgently need global legislation and enforcement of rules, as well as satellite monitoring to stop overfishing. World leaders need to work together on this. Marine ecosystems may not come back once collapsed and that would be a huge disaster. I hope there is some kind of self-limiting dynamic here where industrial fishing becomes unprofitable, but we avoid extinctions and total collapse of ecosystems - but I'm not sure that's the case.

  In fact, tilapia from Vietnam and China are fed pig feces and packed in ice made from polluted water, which is why it's so dangerous to eat them. https://abcnews.go.com/Business/consumers-eating-feces-tainted-shrimp-fish-seafood-asia/story?id=17491264 https://abcnews.go.com/Business/consumers-eating-feces-taint...

    Yep, I wouldn't buy farmed fish from Asia.

      Agreed I avoid shrimp from Asia as well. They are using manure to dose nitrogen but it’s still not a sanitary practice

    Why did you link to a story from 2012? I eat farmed tilapia from Asia all the time with no ill effects.

  "I think we urgently need global legislation" That would require a world government. Not likely to happen and not something I would want to happen for the various potential negative side effects. It is already very hard to control our national governments. International treaties and boycotting and embargos of violaters, maybe yes, but currently the trend is into more confrontation and not collaboration.

    Yes treaties is what I meant. Hopefully more collaboration after November with the new guy in charge!

      Unfortunately the US is not exactly leading on animal welfare, and indeed resists urges to improve. As much as I dislike Trump, this has been the case since long before him. Federal-level animal welfare standards are lacking. Welfare in the US standards are well below that of Europe. Pigs, for example, still often live their short life in stalls so small they can't even turn around - by comparison, the practice of using these "sow stalls" was banned in the UK before the turn of the century. Additionally, the use of antibiotics and hormones is very high.

        Well, but the topic seems to be "how can we avoid that the maritime ecosystem collapse, so we still can eat seafish?" and not "animal welfare". I support both.

So we lack the regulations to do it properly. We should fix that too
