32> 2 FIFTEENTH ANNUAL REPORT OF THE 



Caledonia furnished rainbow trout, brown trout and albino lake trout. 



Delaware Station sent brook trout. 



Adirondack Station, black spotted trout. 



Fulton Chain Hatchery, wild brook trout. 



Pleasant Valley furnished big rainbow trout. 



Oneida Station provided the usual variety of Oneida Lake fishes. 



Mr. Davidson collected yellow perch, strawberry bass, black bass, 

 pickerel, suckers and bullheads, in Lake Salubria. One of the suckers in 

 Salubria Lake weighed four pounds and another one weighed seven pounds. 

 These suckers would prove very useful as trout food at the Pleasant Valley 

 Station. 



Spearing Fish 



On April 25, 1909, Game Protector Farnham sent from Owego a large 

 pike perch which was found dead in the Susquehanna river, at Nichols. 

 Upon examination it seemed evident that the fish had been speared on its 

 spawning bed. Several fish were found dead at that place, apparently 

 killed in the same manner. 



Water Aeration 



Mr. Frank McMillan, of Delanson, N. Y., wrote on August 2, 1909, about 

 a patented apparatus which by a few turns of the crank will fill water full 

 of air. This apparatus, he states, can be constructed for attachment to 

 receptacles already in use or can be put into a special receptacle constructed 

 for the purpose. No description of the apparatus has been furnished. 



Destruction of Algas 



Mr. F. B. Corey, of Keeseville, informed the Commission that there is a 

 dense growth of algas in Auger Lake annually for a considerable time, and 

 he asked for information concerning the use of copperas as an algicide. He 

 was referred to Bulletins No. 64 and 76 of the Department of Agriculture, 

 Washington, D.C., papers relating to " A Method of Destroying or Prevent- 

 ing the growth of Algas and Certain Pathogenic Bacteria in Water Supplies" : 

 also to " Copper as an Algicide and Disinfectant in Water Supplies."
