338 Third Annual Report of the 



Creek. I examined a great many, and in every one the left eye 

 was gone. This I have learned is caused by a parasitic worm 

 which destroys the crystalline lens and in a short time causes the 

 whole eye to drop out. 



A large number of dead fish especially tullibee which had been 

 killed by lamprey eels were seen floating in the lake. One black 

 bass was also found dead. 



There were sent from Oneida Lake to the State Fair at Syra- 

 cuse, September 8 to 14, 1913, 140 adult fish representing twenty- 

 four species. The fish remaining alive after the close of the Fair 

 were taken by the Anglers Association of Onondaga County for 

 planting in Onondaga Lake and Jamesville Reservoir. — Reported

Oneida Hatchery 



On April 18 and 19, 1913, the Fish Culturist inspected the 

 Oneida Hatchery to learn the exact conditions at the end of the 

 pikeperch season. There were at that time in the hatchery 660 

 quarts of pikeperch eggs, all in the very finest shape. No better 

 eggs have ever been seen at the station. Foreman Miller shipped 

 140 quarts to the Pennsylvania Hatchery at Union City, Pa., 

 in exhange for whitefish eggs and other eggs furnished to us by 

 Commissioner Buller. To the Massachusetts State Hatchery at 

 Palmer, he sent 17% quarts of pikeperch eggs as a return for 

 eyed eggs of brook trout given to our Adirondack Hatchery by 

 the Massachusetts Commission last fall. He also shipped 187% 

 quarts to Caledonia, 97% quarts to Linlithgo and 17% quarts to 

 Cold Spring Harbor, in order to divide up the distribution more 

 economically and reach the applicants in various parts of the 

 State more promptly than by shipping all the fry from Con- 

 stantia. 



The number of eggs taken in 1913 was not quite equal to that 

 reported in 1912; but it is probable that the eggs of 1912 were 

 not measured as dry (free of water) as those taken in 1913. 

 Furthermore, the egg taking season dragged along from April 4 

 to April 19 with extremely variable weather alternating with 

 storms and warm days so that the conditions were not normal.
