I can reassure you somewhat, since the testimony I heard from Mr. Krkosek, in my opinion—and I have a feeling that it won't change—is the testimony that shed the most light on the issue thus far.
In addition, as far as the type of containment we might eventually use, I understand that if we have a containment set up in the high seas, in fresh water, or in salt water, and it can hold a certain number of fish, especially salmon, the environment is somewhat different from that in the wild. So, there are various problems that must be either noted, avoided, or verified. Is there an ideal type of containment we should go with? Is there an ideal type of farming we should practice?
