Integrating fish into permaculture systems
My challenge to the
Walden-Effect hive mind is --- can we take the
elegance of an aquaponics system and reinvision it without the
Here are some options I'm considering:

I've read several tidbits about the way traditional Chinese agriculture
integrates fish into their agricultural systems. One system
involves silkworms eating mulberry leaves, fish being fed the sikworm
pupae after the silk is removed from the cocoons, and the fish waste
being dredged up to fertilize the mulberry trees. Humans get
money from the silk and food from the fish with no outside inputs.
Go back to basics. A simple pond full of
aquatic plants, snails, and insects can feed low populations of
fish. Then you could harvest the aquatic plants to turn into
compost or mulch for the garden and eat the fish (or feed them to your
chickens if you'd rather).

we'd want to include tanks of water as thermal mass. Turn those
tanks into fish tanks, make an integrated ecosystem just like you would
in a pond, then scoop out water from time to time to water and lightly
fertilize plants in the greenhouse.
What kind of
fish-related permaculture systems have you seen or dreamed up that
require absolutely no electricity or commercial fish food?
