Why are the blue fin tuna so hard to grow in captivity?

    It’s not so difficult that it isn’t done! They are farmed in ocean net pens in Mexico, for example.

    Tuna are big, fast, powerful fish. So they are not like strugeon, for example, that swim very quietly and happily in shallow artificial pools, soaking up the rays. And miles from the sea. Sturgeon are also huge … but they don’t seem to mind just hanging out. Literally not moving forward or back.

    And legal restriction, at least according to the blog in 2010 cited below, is that the USA does not permit tuna farming in federal water.
