model illustrated attempts to discover means for economizing on 

 expenditures while maintaining the actual output volume of each 

 district within the Donetsk area. In Donetsk, the 1968 fishery 

 output was 26,268 centners of food fish and 3,533 centners of 

 fingerlings; prices were 90 to 120 rubles and 120 rubles per 

 centner, respectively. (One centner = 100 kg, also called a 

 quintal.) The model's objective function, constraints, and 

 related computational formulas are given. Tables of actual, 

 optimized, and saved (according to the model) input usage are 

 given for eight production districts of the Donetsk fishery 

 group, with itemized data for feeds, fertilizers, labor, 

 fingerlings, electric power, and pond area.

 In relation to expected Corps of Engineers requirements that fish 

 farmers obtain effluent discharge permits, a concern is whether 

 or not fish farmers would oe eligible to receive Department of 

 Agriculture cost-sharing assistance for relevant conservation 

 practices. Several precedents are cited to argue that fish farm- 

 ing has been viewed as an agricultural or farming activity and 

 should therefore be eligible for this cost-sharing assistance.

Legal barriers to the development of aquaculture, their removal, 



especially in Arkansas, and fish farming investment, revenue, and 



returns are discussed briefly. Beneficial aspects of fish 



farming are reviewed briefly using data for all or parts of 



Lonoke County, Ark. New jobs have been created, youth interest 



stimulated, and soil and water conservation practices promoted. 



Capital investment has totaled about $833 per acre ($208, ponds 



and water supply; $400, land; other, $225; total, $833). 



Production Credit Association loans total about $6 million and 



are increasing at about $1 million annually. Data on other 



financial sources are not readily available. Net returns per 



acre are indicated for soybeans, rice, cotton, and several fish 



crops.
