permaculture

["Pete Gasper, Gasper Family Farm" <farmer1@gasperfarm.com>]

Purchased sure, but those are all products of land based industries 
(by-products even). So we're avoiding the issues of fish food sourced from 
the sea and opening yourself to the opportunity to source your inputs from 
your own land given that resource or from your local community.

And unless you're feeding just yourself and putting the humanure back into 
the system somehow, you're going to have to have some sort of external input 
(whether purchased or from the land) to make up for the loss of nutrients in 
the meat harvested. I've heard of folks claiming aquaponics with only duck 
weed (grown from the same fish wastes) as a feed but I don't buy it.

What kind of fish are you feeding? How did you come of with this system and 
how are you making the pellets (pelletizing machines tend to be rather large 
scale, finicky things).

Please do share more.

And I think you are on to something with the crawfish. I recently watched a 
video on extensive production of crawfish using no food inputs, the crawfish 
fed on the ecosystem based around the rice chaff in the field. No outside 
inputs, stacking functions. Much more sustainable than farmed fish using 
wild caught fish food.
