returns are shown and discussed. The effects of two feed 

 conversion ratios (1.87:1 and 2.0:1) and two sets of assumptions 

 are indicated, along with the effects of different product prices 

 (range: 25 cents to 65 cents/lb.) on net returns. Organized 

 catfish markets are lacking, investment costs are substantial, 

 risks are many, industry expansion seems likely, if improved 

 cultural practices are adopted, and research ay several 

 government agencies has helped to overcome problems.

Fish farming in twelve south central states (species, acreage and 



number of farmers) . 



Natl. Mar. Fish. Serv. , Current Fish. Stat. No. 6038, 20 pp. 



Results of a 1969 survey of fish farmers in 12 states are 



reported. Of 1241 respondents engaged in fish farming on 75,413 



acres, 804 were growing adult catfish (on 30,330 acres), 429 were 



growing fingerling catfish (on 6,782 acres) and 292 were growing 



minnows (on 26,866 acres). Some 23 aguatic fauna were reported 



as being grown.

Cage culture of channel catfish (1971 experiment). 



Paper presented to the Fourth Annual Convention of the Catfish 



Farmers of America, February 3-5, 1972, Dallas, Tex. Kerr 



Foundation, Inc., 23 pp. 



An experiment was conducted to assess the commercial feasibility 



of cage culture of channel catfish, and the report contains 



itemized data and discussion on production, biological and 



environmental factors, costs, and returns. Study objectives 



related to determination of fingerling size to reach food fish 



size in one growing season, stocking rate, suitability of two 



types of foods, and economic potential. Certain functional 



relations are reported, namely: profit increased with the size 



and rate of fingerlings stocked; total cost per pound of output 



decreased as stocking rate increased, as did average weight gain, 



although total weight gain decreased. Some comparisons and 



problems with commerical operations are discussed.
