328 Third Annual Keport of the 



Bath ^Station 



With the exception of a little gill inflammation in the early 

 season, which was soon overcome by the usual salt baths, our fish 

 have been free from diseases of all kinds. We have, at the end of 

 the first week in October, brook trout measuring 4% inches in 

 length from eggs laid down in the hatchery in December, 1912. 



The work of collecting eggs in Lake Keuka was disappointing. 

 Lake trout that were not ready to spawn would remain in the 

 same condition for days when penned up. We remedied this by 

 putting them in a dark box sunk in the lake. 



Catches of trout in Pleasant Valley stream were very large. 

 This stream contains a large number of water snakes which destroy 

 a great many trout. 



Early fishing in Lake Keuka for lake trout was exceptionally 

 good. 



Our water supply is collected entirely from springs, and has a 

 temperature of 50 degrees, which varies only 2 degrees during 

 the year. The egg hatching period is about 55 days. 



I must again call attention to the need of purchasing 5 acres 

 of land which contain the large springs forming the principal 

 water supply of this hatchery. Cattle, hogs and sheep pollute the 

 water of these springs which would otherwise be ideal for trout 

 culture. — Be ported by Henry Davidson, Foreman, Bath, N. Y. 



Caledonia Station 



The results of work at this station have been unusually good 

 during the past year. In addition to the large distribution of 

 fish (recorded elsewhere) the station furnished 750.000 eyed eggs 

 of brown trout and rainbow trout to the hatcheries at Margaret- 

 ville and Bath. 7,000 eyed rainbow trout eggs to Ithaca Conserva- 

 tory and 33.175,000 green eggs of lake herring to Constantia 

 and Linlithgo stations. We collected also 225 black bass from 

 the western widewaters of the Erie canal. 



The output of lake trout was very small owing to the scant 

 supply of eggs furnished to the Station. With the help of Pro- 

 tector Claude DoVille, the collection of lake herring eggs at Sodus 

 Bav was remarkablv successful. Gill nets were used for taking
