Would you be surprised to learn that China is a world leader in sustainable seafood?  This video shows how fish farmers in China use some ingenious and low-impact traditional methods to produce more fish than any other country.

It’s Slow Food on a massive scale, it’s permaculture, and it tastes great.  Along with fish, the farms produce lovely Chinese silk.  If this was being done by hyper-educated urban refugees, it would be on the front cover of fancy magazines.

Carp are grown in ponds and the rich mud containing fish manure is used to fertilize mulberry bushes.  The mulberry leaves are fed to silkworms, and after they make silk, the silkworm dung and pupae are fed to the fish.  Scientific studies show efficient recycling of energy and nutrients in this thrifty and low-waste system for producing food and a cash crop.

Modernization is putting pressure on these traditional fish farming systems, as land and labor costs go up.  Fortunately, scientists in China are looking for ways to retain the ecological value of these fish farming methods as farmers strive for higher income.

Can China succeed where most of the West has failed, retaining traditional food production systems that could lead to a truly “green” economy?
