An integrated system of aquaculture,vegetable production and solar heating in an urban environment

This study investigates the feasibility of an integrated system of fish culture with vegetable production and solar home heating in an urban environment. Tilapia aurea and lctalurus punctatus are polycultured in a semi-closed pond system located near downtown Atlanta, Georgia. Fish culture is integrated with vegetable production and composting in order to recycle fixed nitrogen and avoid the use of commercial fertilizers. Water quality in the greenhouse pond is maintained by settling processes and by the use of simple biological and solar methods. Cost analysis of the total project is presented and recommendations for system improvements are given.
