摘要

In most intensive aquaculture systems, a stock is raised under stressed environmental conditions with little regard for ecological balance. To compensate for these unnatural conditions, managers often rely heavily on formulated feeds, chemical treatments and water exchanges to raise and harvest their stocks before the system becomes too stressful for optimum growth and survival. Managers risk high production costs, stock mortalities and the degradation of habitats that receive effluents (Briggs and Funge-Smith 1994). Dalsgaard et al. (1995) explained the concept of ecological sustainability as maximization of internal feedback within a culture system. Such a system would minimize inputs and wasted outflows of resources.
