Table 1 . --Production of channel catfish over a period of 100 days 

 when maintained at two differing densities in identical halves 

 of a pond separated by a coarse-mesh screen. 



Table 2. — Comparisons of production data from fed and unfed popula- 

 tions of channel catfish when stocked as fry at differing den- 

 sities in 1-acre (0.4-hectare) ponds. 



Table 3 . --Comparison of the production of channel catfish free in 

 1-acre (0.4-hectare) ponds with production by equal numbers 

 confined in cages. Data presented represent averages for 

 four ponds with 1500 catfish free in each pond, and for four 

 ponds with 1500 catfish divided between two cages floating in 

 each pond. Average individual weights were 11.8 grams when 

 stocked May 6, 7, and 8, 1969. All populations were censused 

 in the period October 6-17 after growing periods ranging 

 between 150 and 160 days. 



Table 4. — Comparisons of growth of caged channel catfish in a 



heavy-use boatdock area of a 585-acre (236.7 hectare) reservoir 

 with growths made by catfish maintained at equal cage den- 

 sities in undisturbed small ponds. The numbers of uncaged cat- 

 fish released into the ponds raised the total densities to 

 approximately 3,707 channel catfish per hectare. 



Table 5. — Comparisons of rates of production of channel catfish in 

 a raceway and a 1-acre (0.4-hectare) pond.
