The design of an aquaculture enterprise. 



Proc, Gulf Caribb. Fish. Inst., 24th Annu. Sess., Nov. 1971, pp. 



117-125. 



Among the factors judged to be important in determining the 



success of an aquaculture operation are those having to do with 



site selection, which the author emphasizes in this paper. 



Selection of sites is discussed with reference to ranch, pond, 



raceway, cage and closed (high-density) methods of culture. A 



comprehensive, extensive list of site selection criteria is 



provided .

Bisks to the aquaculture enterprise. 



Aquaculture 2(2): 157-172. 



Successful operation of an aquaculture business requires 



ent €r preneurship, knowledge of biological process uncertainties, 



management skill, and sufficient capital resources to achieve 



appropriate economies of scale. Risk aspects of commonly used 



problem or management areas for a hypothetical enterprise in the 



American Tropics are discussed independently, but their 



interdependence is recognized. Biological risks include diseases 



and parasites (a major problem), seed production, predation and 



competition, inventory control (serious since it impairs 



management) , nutrition, and natural productivity. Physical risks 



include water quality and storm damage. Social and economic 



risks relate to political stability (in developing countries) , 



land, labor, poaching, feed costs, and market changes. The 



discussion details the nature of various risks, and offers 



suggestions on possible degrees of risk interaction and risk 



losses in qualitative terms.
