Biological and economic criteria are developed and applied to the 



selection of species for relatively large scale commercial 



aguaculture development and/or support by public agencies. The 



biological criteria include environmental adaptability and 



intensive culture adaptability (specifically, after Ryther and 



Bardach, 1968, reproduction in captivity, hardiness of eggs and 



larvae, easily satisfied food reguirements, and growth speed) . 



The economic criteria include market price and volume, potential 



interregional competition, competition from natural supplies, and 



the institutional or legal setting (regarding rights to water 



column or bottom, and environmental quality) . Ey assigning 



numerical values to 6 of the criteria, 6 of 21 species or fash 



groups evaluated were selected for possible development and 



support in New England.

Aguaculture in less developed countries: some economic 



consideratio ns . 



Preprints of 7th Annual Conference of Marine Technology Society, 



Wash., D. C, Aug. 16-17, 1971, pp. 579-583. 



The benefits of aguacultural development, transforming 



traditional aguaculture (analogous T.W. Schultz's analysis of 



agriculture) , and the public sector role in this transformation 



are discussed. Benefit-cost analysis is suggested, with special 



attention to factors that may affect benefits, such as 



supply-shift effects on price, current prices, potential market 



size and growth, and marketing efficiency and cost. The 



importance of market incentives, public R&D, use rights, credit, 



the relationship between urbanization and market system 



efficiency, and other factors are discussed. The public sector 



role relates to institutional aspects of rights, externality 



effects of new technology, research funding and direction, and 



the recognition of the importance of fish in the consumers* diets 



so far as R8D leadership are concerned.
