In making the census It was of unusual Interest to find that almost without exception 

 each fish species was represented by very large and by coDi)aratlveIy small individuals. Obviously, 

 the large fishes represented those that survived the winterkill of 1944r45, and the small fishes were 

 those spawned during 1945 and 1946. The effect of thinning upon the population surviving the winter 

 of 1944-46 was evidenced by the unusually large sizes of some of the fishes. 



As may be seen In table 1, fish of the following species survived the winter of 1944-45; 

 white crapple, green sunflsh, black bullhead, carp, buffalo, and golden shiner., 



Many thousands of small fishes were in evidence. In the cases of crapples, green sunflsh, 

 bullheads, and golden shiners, the number of these small Individuals for each species was estimated 

 by the following procedure: (1) for each species, five lots of 100 small fish were weighed In order 

 to obtain a good average weight figure for Individuals. (2) The remaining fishes that had been col- 

 lected were separated according to species and weighed In lots of 25 to 30 pounds; the number of In- 

 dividuals In each lot was calculated on the basis of the average weight figures obtained from (1). 

 (3) Visual estimates of the numbers that could not be reached by boat were made for each species, and 

 corresponding weight was calculated by use of the average weight. Thus, the total numbers and total 

 weights of these four species are approximations. 



At least 76 white crapples survived the winter of 1944-45. They averaged 1.3 pounds each In 

 1946 and varied In weight from 0.75 to 1.5 pounds. These crapples were not exceptionally large but 

 may be considered to have grown rapidly after the winterkill If, previous to 1945, they were of 

 average weight for white crapples In most artificial lakes (less than 0.5 pound each). The 42,500 

 small white crapples varied In length from 2.8 to 3.2 inches and were spawned probably In the spring 

 of 1945. 



Only 17 green sunflsh were believed to represent the survival by this species of the winter 

 of 1944-45. These were quite uniform In size and averaged less than 0.25 pound each. The spawn of 

 1945 was .estimated at 4,580 Individuals averaging 1.9 Inches In length and 0.016 pound each In weight. 



No largemouth bass were taken In the census, and only one blueglll, weighing approximately 

 0.25 pound, was collected. 



One hundred twenty large black bullheads were collected, averaging .069 pound each. These 

 varied In weight from 0.5 to 1.0 pound. Their young were even more numerous than those of the white 

 crapples and were estimated at 48,700. These little bullheads averaged 2.8 Inches In length and few 

 of them varied more than cne-fourth Inch from the average. 



The carp population consisted of 219 large fish, which ranged In weight from 4 to 15 pounds 

 (average weight, 7.18 pounds) and 1,331 small fish averaging 0.44 pound each. The small carp were 

 spawned probably In 1945.
