Quite tragic the way that Tuna and other fish are being overfished. Tuna are like the tigers of the sea, they are at the top of the food chain. I just don't see

Quite tragic the way that Tuna and other fish are being overfished. Tuna are like the tigers of the sea, they are at the top of the food chain. I just don't see a way that we're going to stop before an environmental catastrophe.

Problem is, even if we stop fishing and decide to not touch a single fish in an ocean, our pollution and the global warming, will turn oceans into an acidic (as in as acidic as regular rain gets) cesspit of jellies. I don't mean - go on and farm every last one of them, just that it will soon become an extinct creature, simply because we fucked up its environment beyond repair already.

  Sorry, but could you back up your statements with facts? This sounds to me as a rather generic statement. I have no idea about the adaptive capabilities of tuna, nor do I know the actual change in pH values, or levels of chemical pollution. Overfishing and the collapse of ecosymstems in the ocean is major factor (see also whales, sharks, etc).

    Of course. Problem is that ocean acidification (low pH) gives jellies advantages http://www.sciencedaily.com/releases/2012/12/121231180617.htm http://www.sciencedaily.com/releases/2012/12/121231180617.ht... http://icesjms.oxfordjournals.org/content/65/3/414.full http://icesjms.oxfordjournals.org/content/65/3/414.full http://www.spc.int/oceanfish/en/publications/doc_download/728-pfrp-proposal-ocean-acidification-impacts-upon-tropical-tuna-populations http://www.spc.int/oceanfish/en/publications/doc_download/72... Though some analysis point that there are no benefits to jelly fish. http://aslo.org/lo/toc/vol_53/issue_5/2040.pdf http://aslo.org/lo/toc/vol_53/issue_5/2040.pdf Generally, from what I've heard, the global warming is already straining the metabolisms of the existing sea creatures to a breaking point. Problem is we need to a super sharp CO2 reduction right now, to just keep the climate as it is now (i.e. patterns of extreme weather) and hope to restore balance within 50 years. This is ofc based on simulation so God knows, how accurate it is...

      Hi, thanks for the papers! I will have a look on them.
