Interest in aquaculture has increased and will increase further, 

 given the problems created by rapid human population growth and 

 the growing, but finite potential output of protein. Diverse 

 problems must be recognized in aquaculture 's development. A 

 schema of four phases is presented, during which a decision to 

 proceed or discard a species can ce made. The four phases 

 include species selection, oiological research, field trials, and 

 assessment of socio-economic factors. Phases are suc-divided , 

 and indicate a multidisciplinary approach, with government- 

 supported R&D, and government-industry partnership ventures 

 suggested at various steps.

and amimals that are cultivated for food and the methods by wnich

General principles and economics. 



Ch. 1 of their aquaculture; the farming and husbandry of

pp. 1-28. 



The economics of particular aquaculture ventures are considered. 



The focus is on costs of production, rates of return of 



investment, price cross elasticities of demand among fishery 



products, and the supply and demand for various species. 



Comparisons are made among countries engaged in aquaculture as to
