Evaluation of the commercial feasibility of salmon aquaculture in 



Puget Sound. 



U.S. Dep . Commer., Natl. Mar. Fish. Serv., H.N. Fish. Cent., 



unpubl. prelim, analysis, 35 pp. 



Topics include descriptions of biological and ecological systems, 



and analyses of production costs, marketing, and cost and returns 



for a salmon aquaculture operation the size and structure of 



Ocean Systems, Inc. (now Domsea) activity, which is based on R&D 



work by NMFS and partial funding by Sea Grant. Capital equipment 



initial costs, estimated lives, and amortized annual amounts are 



shown, along with operation and maintenance costs (for labor, 



eggs, utilities, maintenance, heated water, leasing, and 



permits), and finally total annual costs, by function 



(incubation, pond rearing, and pen rearing, then total) and cost 



item. Uncertainty ("risk") returns necessary to encourage 



investment are discussed as to causes, results, effects of 



reduction, and relation to limitations and restrictions of entry 



into aquaculture. Assuming the market would support prices 



sufficient to cover the opportunity costs of resources used, plus 



an initial return for risk, preliminary analysis suggests that 



salmon aquaculture is economically feasible, but there are some 



serious information qaps.

Economics of hatchery salmon disposal in Oregon. 



Oreg. State Univ., Mar. Advisory Progr., Sea Grant 17, 20 pp. 

 The sale of salmon returned to hatcheries as opposed to the sale 

 of commercial salmon in Oregon is discussed. The Fish Commission 

 of Oregon (FCO) set up a grading system in 1971 to judge the 

 quality of returned hatchery salmon. A grade of 1 is given those 

 fish returned in good condition. No restrictions are put on 

 their use. Grade 2 means that fish could be used for any purpose 

 other than in the fresh or fresh frozen market. Grade 3 

 indicates that the fish is in poor condition and may be used for 

 nonhuman consumption only. Hatchery sales from 1968 to 1971 were 

 between 4.7% and 6.5% of commercial landings. A tabled 

 comparison is given of utilization of surplus coho and chinook 

 (as fresh market, canned, smoked or kippered, animal food, crab 

 bait, rendered, or dumped) . More salmon was used in the fresh 

 market in 1970 (36%), but that figure declined to 19% in 1971. 

 Oregon is a surplus producer of seafood. Data on markets are 

 given for FCO hatchery sold salmon (1968-71) in Oregon, 

 Washington, California, other States, and other countries. The 

 conclusions include (1) due to the FCO grading system, the sale 

 of poor quality returned salmon for human consumption has
