produce items that have received consumer acceptance. Of course, 

 technological problems require further work in developing a 

 system for high-yield, low-cost cultured fish, and they relate to 

 space (area or land) , water (temperature, treatment) , feeds and 

 feeding (the largest cost item) , mechanization of present 

 labor-intensive activities, disease, efficient processing 

 technology, pollution controls, and the development of markets 

 and consumer acceptance.

A perspective of the problems of aguaculture development and the 

 role of economics are discussed. While the agriculture- 

 aguaculture analogy is often cited, certain institutions have 

 become established for agriculture, but not for aguaculture, 

 namely tenure and use rights, credit, research, extension, and 

 ccst-price controls, many with government involvement. Econo- 

 mists can assist in the development process by providing analyses 

 of institutions, demand, simulated costs and returns, capital 

 budgets, and regional and local impacts. Early, cooperative 

 interdisciplinary efforts to determine species selected, informa- 

 tion needs and uses, etc., are suggested. A large, social RSD 

 commitment (as to agriculture) is essential to aguaculture 

 development.

Aguaculture: economic feasibility in the Great Lakes area.

Potential interest in aguaculture in the Great Lakes region is 



suggested on the basis of preliminary findings respecting both 



commercial food and recreational fishing. Processors and dealers 



formerly dependent on higher Great Lakes landings would provide a 



marketing medium, especially for such species as yellow perch, 



pike, and trout, but perhaps not catfish, except for certain 



areas. However, consumer and market preferences vary within the 



region. Lack of information dissemination, credit to start risky 



ventures, and a technology to provide warm water are among the
