Cost-size relationships in the production of pond-raised catfish 

 for food . 



Miss. State Univ., Agri. Forestry Exp. Sta., Bull. 792, 69 pp. 

 Itemized costs and returns are provided for six farm situations, 

 based on six sizes of ponds (5, 10, 20, 40, 80, and 160 acres) on 

 160 acres of land, and based on specified methodology, assump- 

 tions, and detailed supporting data. Input-output coefficients 

 were synthesized on the basis of information from several 

 sources, and factor prices were applied to estimate costs. 

 Investment, cost, and return data are summarized in tables and 

 one figure (which shows per-pound average total, operating and 

 ownership costs as a function of pond size) . Sensitivity anal- 

 ysis results indicate separately the effects of changes in 

 fingerling and food costs on average cost of output, and of 

 changes in output price on various measures of net income. Farm 

 situation III (20-acre ponds) had the lowest average cost of 

 output and highest net return, but no substantial net return 

 differences occurred among farm situations III, IV, and V. The 

 appendix provides detailed tables and discussion on input usage, 

 labor time reguirements, equipment and capital costs, pond 

 design, and other variables.

Catfish production in Southeastern Arkansas: estimated 



investment requirements, costs and returns, for two sizes of 



farms. 



Univ. Ark., Agri. Exp. Sta., Div. Agri., Rep. Ser. 203, 27 pp. 



Estimates were made of investment costs, and annual costs and 



returns for a 40-acre farra with a 33-acre pond and a 160-acre 



farm with four 33-acre ponds. The data used were based on farm 



surveys, specified assumptions, and other information. Using 



itemized budgets, the costs and returns are compared for the two 



sizes of farms and economies of scale are shown. The effects of 



five price levels and six production levels are shown, 



demonstrating some aspects of risk.
