Norwegian pondfish farming. 



Paper presented at Internatl. Symposium on Fisheries Economics, 



Paris, Nov. 29-Dec. 3, 1971. O.E.C.D., FI/T (7 1 ) 1//25, 29 pp. 



This is a condensed version of a longer, Norwegian-language 



report. Based on 1966 and 1970 survey information, the Norwegian 



pondfish industry is descrioed and analysed in economic terms to 



explain variations in profits and costs. The output, mainly 



rainbow trout, increased from 200 metric tons in 1962 to 1,000 



metric tons in 1969. Variable, fixed, and total costs for some 



of the 260 firms are shown and discussed along with other data to 



show variation in labor and capital costs per kilogram of output. 



Investment, stocking, feed, and other cost items are discussed. 



Small firms (10 to 15 metric tons per year of output) provide
