ABSTRACT:
A dietary inclusion model for an integrated aquaculture-hydroponics system is derived from the concept of mass conservation. The model enables the maintenance of near-equilibrium concentrations of Ca, K, Mg, N, and P, suitable concentrations of Mn and Cu, and acceptable accumulation rates of Na and Zn, in representative integrated aquaculture-hydroponics systems, by modifying the mineral concentrations of the fish diets according to the model. The model is readily applicable to virtually any freshwater recirculating fish culture system operating at a recycle ratio sufficiently high to maintain appropriate nitrogen concentrations and having an environment suitable for hydroponic plant culture.
