International developments in fish production. 



O.E.C.D., Paris, 179 pp. 



Contents include: discussions for regional oceanic waters, 



certain fisheries and fish culture with respect to member country 



fishing activity; a survey of world fishing capacity; and 



appendix tables. Growing demand for fishery products, and 



natural-stock supply growth limitations and problems are the 



primary justifications for fish culture development. Limitations 



include high ratios of initial investment to annual output 



(perhaps 2:1 or 3:1) compared to natural stock harvesting firm 



ratios (perhaps 0.3:1 to 1:1), additional investment during the 



start-up period when money outflow exceeds money inflow (negative 



net cash flows) , technology problems, and risks. A belief tnat 



cultured output could be increased fivefold by 1985 is viewed 



more in the realm of technical than of economic possibility.

NOAA aguaculture survey, 1972, summary report to participants. 

 (Also called the Mardela report.) 



Burlingame, Calif., Mardela Corp., a Sea Grant project report, 

 60 pp . 



The objective "was to define priority research areas in order to 

 move from the laboratory to commercially viable aguaculture at 

 the earliest possible time." Twelve 1-day regional workshops were 

 held involving some 180 participants from universities, business, 

 and government, so as to "achieve a representative cross section 

 of individuals and organizations active in the region," although 

 the " (e) xpertise and experience of respondents lay mostly in the 

 biological disciplines." Preworkshop guestionnaires and 

 structured meetings were used to identify transition obstacles 

 for marine, anadromous, and brackish- water species, but not for 

 aguarium and freshwater species. Briefly, three general areas of 

 concern are detailed: policy and organization, other nontech- 

 nical factors, and technical needs. Research priority -needs and 

 feasibility evaluations are scaled in tables based on participant 

 responses.
