on loan from NMFS.) 



While the author does not discuss aquaculture per se, some 



differences between and similarities of sea fisheries and 



agriculture are discussed with particular emphasis on the methods 



and tools of comparison. Among the differences are: (1) 



geographical placement of fisheries reach far beyond national 



boundaries and enlarges the country's territorial food base, (2) 



decreasing returns appear in all cases where arable land and 



fishing banks are constant and the remaining production factors 



increase successively, though less in fisheries than farms, (3) 



no capital expenditures occur for fish production base, (4) 



structure of fixed assets and variety of farm produce differ. 



The main similarity is the close connection of productive 



activity and nature and the accompanying risks. Weighing 



products, wages in the two fields, scope of the comparison, 



assumption of certain operating conditions and circumstances in 



both branches, selection of reference units to calculate indexes, 



and proper interpretation of results are among the items included 



in a discussion of methodological problems and procedures 



pertaining tc comparison.

Income potential from outdoor recreation enterprises in rural 



areas in Ohio. 



Ohio Agri. Exp. Sta., Res. Bull. 964, 51 pp. 



Fishing and pay-lake operations are included in the report. The 



purposes of the study were to provide information on the number 



of recreational enterprises in the unglaciated area of 



southeastern Ohio, and to provide data on land, labor, and 



capital requirements; costs and income; operator characteristics; 



and management and technical problems for seven of the more 



popular types of rural enterprises commonly provided via private 



capital. A sample of 31 enterprises (5 pay lakes) was selected 



from an estimated population of over 250 firms in a 23-county 



area, and the financial data are for 1961. Catfish, bass, and 



bluegills are the most popular stocked fish, but some lakes also 



stock other species. Itemized capital investment, income and 



expenses, net cash income, and returns to family labor and 



management for the five paylake operations are shown (average and 



range data for all items) . Numerous factors are analysed using
