Crayfish anyone?

I am convinced that here is huge potential for raising “Crawdads”  in urban farms.

They can be fed vegetable waste and hay from the farm, and: “Freshwater crayfish are highly regarded as a delicacy as they are very similar to shrimp or lobster in taste and texture…high protein and low-fat.”

I found a few books about raising Crayfish, it would be worthwhile exploring possibilities for integrating them into a medium-scale aquaponics system:

Finding a fishy solution

Microbiologist devises a model for sustainable urban farming

Posted by Greg Rienzi on the JHU Gazette August 1, 2011

There’s something fishy going on at Baltimore’s Cylburn Arboretum, and the results could be delicious—and sustainable.

Earlier this summer, David Love, a microbiologist and project director with the Center for a Livable Future at the Johns Hopkins Bloomberg School of Public Health, began work on a demonstration aquaponics farm housed in a greenhouse at Cylburn, a nature preserve located in north-central Baltimore.

Aquaponics, a relatively new and unknown sustainable food production system, is the merger of aquaculture, or fish farming, and hydroponics, soil-less plant farming. The system utilizes fish wastewater as a resource by circulating it through hydroponic grow beds, where plants uptake the waste as their primary nutrient source. In the system, a symbiotic relationship is formed between fish and plants, with fish providing most of the required nutrients for the plants, and the plants in turn cleaning the water for the fish.
