Arthur T Knackerbracket has processed the following story:
It has been claimed that fish farming is a sustainable source of food that will help us feed the growing global human population while protecting wild fish populations – but this isn’t true.
“Fish farming is not a substitute for catching wild fish out of the ocean,” says Matthew Hayek at New York University. “In fact, it relies on catching wild fish out of the ocean.”
Hayek and his colleagues have shown that the amount of wild fish killed in order to feed farmed fish is between 27 and 307 per cent higher than previous estimates.
Farmed carnivorous fish eat multiple times more weight in wild fish caught from the ocean than is obtained by farming them, says Hayek. For instance, producing a kilogram of salmon may require 4 or 5 kilograms of wild fish.

In my experience, anything built in a marine environment requires more than modest effort to maintain. Salt corrosion, sun exposure, wave action, extreme storms... there are precious few locations in our vast oceans that provide year round ideal circumstances for... anything.
Along those lines, in my next lifetime - Matrix reset to 1960 - I would pursue the business of luxury submarine yachts. Go anywhere you like, but when a bad storm is closing in, submerge instead of scrambling for safe harbor. Make 'em big, out of cast concrete with non-rusting composite tension elements (instead of the traditional iron or steel rebar). Build once, cruise for centuries. Smuggle some 2030s solar panel and battery tech back to 1960 and make them self-sustaining mobile islands, producing their own fresh water and food.
Only problem is: a $1B concrete submarine yacht probably only has carrying capacity for a dozen or so people, long term, even if it could host an exclusive short term party for hundreds. Looks like Hugo Drax did have the right inevitable conclusion after all in Moonraker.
