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 densities 

 in undisturbed small ponds. The numbers of uncaged catfish re- 

 leased into the ponds raised the total densities to approximately 

 3,707 channel catfish per hectare.
