They were already selling expensive seafood before, presumably with profit, why should that have changed? I imagine for a few years part or all of their profit will go to the lender while the pay back the loan. Then it's all for them again, except they're now owned by the trust instead of by the previous shareholders.

The point of having a trust is not to form capital, but to enforce a certain company governance system (as described in the legal documents with whom the trust is set up) without tying it to who happens to be the owner at any given moment.
