contraints to aquaculture development. Use of powerplant thermal 

 effluent is in the promising experimental stage, with recognized, 

 but hopefully manageable problems. Long-term market demand may 

 be slow growing without promotion, because of relative (cited) 

 income elasticities for fish and meat from warm-blooded animals.

Method of planning, recording and calculating the prime cost of

 loan from NMFS.) 



Methods of recording expenditures and calculating the production 

 costs of pond fisheries are discussed. The processing method is 

 recommended. In the process of fish breeding there are stages or 

 phases, each with a marketable output. They are (1) breeding of 

 fingerlings, (2) breeding of underyearlings, (3) wintering, and 

 (4) fattening of the fish. For each phase the calculation for 

 the fish bred and their marketable guantity should be prepared. 

 How to calculate and record direct and indirect expenditures as 

 well as how to distinguish between production expenditures on the 

 output of commodities and those on unfinished products is 

 discussed and illustrated. What should constitute prime costs 

 for each stage of unfinished production is outlined.

Vodnany, Czech., Fish. Res. Inst., pp. 17-21. 



The author reviews the history, current developments, and future 



prospects for fish farming in Yugoslavia. There are 20,000 



hectares of carp ponds. Output doubled in 10 years to 20,000 



metric tons of carp in 1970, with carp representing 89% of the 



weight of cultured fish production. Also, 300 metric tons of 



rainbow trout were produced. The use of pelleted feeds is 



increasing. Chemical stimulation of carp ovulation, carp disease 



studies, preventive measures, and treatments are also discussed.
