Economic efficiency of breeding herbivorous fishes in ponds

This report compares the economic efficiency of the increasingly 



important herbivorous fish culture with that for carp. Output 



data are given, and operations in the Konstantinovka district of 



the Donetsk fishery combine (firm) are used for purposes of the 



study. Twc-thirds of the district's assets are in production 



ponds (totaling 44 ha) , and amortization of the capital cost is 



allocated between fry and market fish culture. Several tables 



and discussion are used to indicate acreage, capital investment, 



labor expenditure, production, revenue, and itemized cost and 



return data. For example, among the comparisons made, the 18.4 



ha water supply pond had a yield of 0.69 metric ton/ha of carp, 



and 0.19 ton/ha of herbivorous fisn, but profit was 14.0% of 



expenditures (12.2% of market receipts) for carp and 37.8% of 



expenditures (27.5% of market receipts) for the herbivorous fish 



in 1967. This activity produced market fish. A similar 



comparison is made for fry production. 



Subject descriptors: 



Carp; herbivorous fish; firm data; revenue; costs; returns; 



investment; enterprise comparison.

1973. 



Japan's eel fishery. 



Mar. Fish. Rev. 35(5,6): 41-45. 



Discussed are culture methods, output (1952-70 data) , marketing, 



recent prices (1971 to 1973), import data (1970 to 1972), 



quantity and value, and prices by country, import duties, and 



U.S. export opportunities. In the period 1952-70 output from 



inland fisheries remained relatively stable around 3 to 4 metric 



kilotons, while cultured output rose from less than 1 to over 20 



metric kilotons. Juvenile eel (elver) prices increase as size 



decreases for culture purposes.
