understanding the degree of competition between the two sources 



of supply.

In the absence of established U.K. commercial operations from 



which revenue, cost, and return data might be obtained, any 



attempt at an assessment of the economic feasibility of marine 



fish farming must be rather speculative. Yet, it is useful to 



examine some of the possible production costs for guidance as to 



which species are most likely to provide positive returns. Items 



of cost are listed in the leaflet and costs estimated for labor, 



tanks, juvenile stock, and feed, with 10% added for overhead, 



repairs, and clerical expenses. Various prevailing technical and 



economic factors affect the assessment and judgement on species 



ranking at any point in time, but it now appears that effort 



should be concentrated on the R&D for high-priced species in the 



United Kingdom, such as turbot, dover sole, hake, and halibut, 



but not red sea bream and plaice. (Based on ASFA abstract.)

This article presents a checklist of items to consider before 



investing any sizeable sum in a fish-farming endeavor. Among the 



items are information sources, economics, management, marketing, 



physical features of the production complex, source of 



fingerlings, feeding, harvesting, transporting, and marketing.
