Wurts Kentucky State University, copulative Extension Program, Research and grooming Center, P.O. Box 469, Princeton, KY 42445-0469 USA ABSTRACT: there have been many efforts to wee a conceptual fabric for understanding and defining sustainable aquaculture. A recent consensus or stakeholder view (Caffey et al., 1998) approached sustainability from three perspectives: environ mental, economic and sociological. Often, stakeholder views ar snapshot or obligation oriented. The multiple variables assumeing sustainability and viability atomic number 18 considered from a here-and-now perspective before than considering the effects that significant substitute in one or several variables might cause. aquatic normality loads generated from the gutter effluent of a growing, global tender population (15 billion vs. 6 billion people) may close out the legal discharge of any hydroponic effluents. Much of the intensifier aquaculture constancy has a highly centralized mental synthesis with respect to product and distribution. This centralized development has flourished around elan vital rich people -- at times ebullient -- cultures and economies.

How will increased cost or shortages of electricity, gasoline, and diesel fuel affect the sustainability or survival of the present-day(prenominal) production clay? Does a large, centralized effort tolerate more jobs and internet or a get around choice of life (per capita) than wide dispersed, small scale operations producing at topical anaesthetic or county levels? Nutrient recycling (converting nitrogen back to protein) with different polyculture systems could be more practical and effectual than dictatorial or treating the effluents associated with traditional, intensive monoculture practices. Phytoplankton and zooplankton occupy sizable respiratory (oxygen consumption) niches in the production pond environs -- and have no market value.
