This study integrates relevant biological and utilization factors 



into one model of the world demand and supply for seafoods. 



Decennial projections of anticipated consumption and prices are 



made for the period 1970 to 2000 within the framework of the 



model. Fish studied include tuna, salmon, groundfish, halibut, 



sardines, shrimp, crabs, oysters, clams, scallops, other food 



fish, and reduction fish (for oil and fishmeal) . With the 



exception of sardines, oysters, clams, and scallops, it is 



estimated that all of the species will reach the point of maximum 



sustainable supply (MSS, not necessarily the same as maximum 



sustainable yield, MSY) in the period 1985 to 2000. Aguaculture 



is specifically considered in the projections for oysters, clams, 



and salmon (hatcheries only) .

Aguaculture for developing countries. a feasibility study. 



Cambridge, Mass., Ballinger Publishing Co., forthcoming. (The 



authors are with Dep. Econ. , Fla. State Univ. and provided a 



copy of a preliminary draft, 138 pp., as submitted to U.S. Dep. 



State, Agency for International Development, under contract, 



1974.) 



The authors selected 14 presently cultured plant or animal 



species and 90 less developed countries to test hypotheses about 



the feasibility of technology transfer of aguaculture operations. 



Species and country groupings are employed in accord with 



combined scores which are based upon separate scores for 



substitution, demand and technological acceptability. A 



bioeconomic model is developed for estimating production, 



employment and foreign exchange effects in relation to small farm 



operations. Judging by one or more of these effects, about 



one-third of the countries could benefit from aguaculture. The 



importance and difficulty of economic analysis are emphasized.
