We already have ponds for growing non saltwater fish. Farming cattle fish in the ocean would be interesting!

There are already many aquaculture pens in the ocean near Port Lincoln, South Australia, often for tuna. You see them from the air when flying over. Here's a photo of what they look like: https://www.cleanseas.com.au/custom/files/media/our-farm-2.jpg https://www.cleanseas.com.au/custom/files/media/our-farm-2.j...

  The issue is that many of the desirable farmed fish like tuna and salmon are carnivores. Farming them still requires catching mass quantities of less-commercially-useful fish along with the issues that has. Edit: I should say part of the issue. There are other ecological concerns with farmed fish.

    That and the flesh eating parasites eating the farmed fish alive. So the inputs are unsustainable. The output yields are unreliable, and not able to meet demand. It isn't clear how much better fish farms are for the environment.

Nations in the far east already have have vast fish farms in the ocean (along the coasts). They are huge and produce huge quantities of fish -- a substantial percentage of fish consumed. But there are species that people like to eat that cannot be farmed economically or at all. So they are caught in the wild.

  Worth noting, fish farms have flaws that have not been addressed yet. E.g. - there is a parasite that attacks the flesh of farm raised fish. The fish literally get slowly eaten alive. Scientists still trying to find a good solution that scales. Currently, the yields in commercial fish farms won't meet consumption demand. IMO, it is probably better to eat meat than fish. We at least have a better understanding of how to more sustainably raise cattle. I'm probably not entirely accurate here, but cattle do not have the same level of ecological importance as fish do.
