to subsequent spawning success. The author entertained some doubt that the 

 bass would reproduce during the first year since they were stocked rather 

 late in the spawning season (May 12 and 19) and at sizes considered near or 

 below the minim\im at which bass can successfully reproduce, Bass of three 

 sizes were used, all of which were one year old. In the group averaging 4,9 

 inches, the range was 4„1 to 6.1 inches. This size was stocked in four clear, 

 in three intermediate, and in one muddy ponds. No reproduction was found in 

 any of these at the end of the first year. In the size group averaging 5.4 

 inches, the range was 4.9 to 6.5 inches. Reproduction was found in 3 of 4 

 clear ponds, 1 of 4 intermediate ponds, and in of 5 muddy ponds in which 

 this size was stocked. In the group averaging 6,6 inches, none of the bass 

 was longer than 7,6 inches. Reproduction was found in 4 of 4 clear ponds, 

 3 of 6 intermediate ponds, and in of 3 muddy ponds in vrhich they were used. 

 In the 11 ponds exhibiting reproduction, the size range of the recovered 

 young was 1,7 to 6.4 inches; the average was about 3.6 inches. Recovered 

 young in the seven clear ponds had an average length of 3.7 inches, com- 

 pared to 3.5 inches for the young foxind in the four ponds of intermediate 

 turbidity. 



The previous discussion has considered only the occurrence and not the 

 rates of reproduction. Table 5 gives the total weights of young recovered 

 from the 12 ponds for which total populations were estimated. For redears the 

 average production in clear ponds (100.3 pounds per acre) in 1955 was approx- 

 imately 3 times that in the intermediate ponds (32.5 pounds per acre), and 

 over 300 times that from the muddy ponds (0.33 pounds per acre). Weight of 

 young bluegill in clear ponds was approximately 18 times that in the muddy 

 ponds. It should be pointed out that only two clear and two muddy ponds are
