The farming of fish in protected waters has been thought of as more sustainable than fishing in the ocean with nets, but growing large numbers of fish in a concentrated area has its own environmental issues. So now, 22-foot fish-farms called “aquapods” are floating freely out in the ocean and growing schools of Kona Kampachi (also known as “Almaco jack”) with no apparent negative environmental effects. They’re tethered to manned vessels that float off the coast of Hawaii. Biologists at Hawaii’s Kampachi Farm are doing they testing, and they say aquapod fish-farming is the most “impact-free form of food production on the planet,” and “the fish are where they are meant to be…in the ocean.” [grinning fish swims by] Happy fish!

Traditional fish farms pack in too many animals, resulting in disease and toxicity. One Hawaiian company has innovated floating 22-foot spherical cages that circulate in the open ocean with low environmental impact.
