Placid, Canandaigua Lake, Seneca Lake and Lake Ontario, in April, 1909. 

 In November, 1908, we planted 338,500 yellow perch fingerlings in twenty 

 different bodies of water in the State. The eye trouble has not been so 

 bad the past season as it was a year ago. 



We have five of the bass hatching ponds completed now and the 

 remaining one is nearly finished, so I think we will have them all in running 

 order for next spring's hatching. The muskrats have been more trouble this 

 fall than ever before in the bass ponds, boring in the banks. The lamprey 

 eel is becoming a very serious thing in Oneida Lake. During the months 

 of July and August last the surface of the lake was literally covered with 

 dead fish, most of them cisco and pike perch, about all with lamprey eel 

 marks on them. 



The following fishes were obtained from Oneida Lake for exhibition 

 at the State fair at Syracuse: 12 pike perch, 9 yellow perch, 5 pickerel, 

 1 great northern pike, 10 sunfish, 5 small-mouthed black bass, 10 rock bass, 

 4 bullheads, 2 lake chub, 2 golden shiners, 1 lamprey eel, 8 crawfish, 10 

 small-mouthed black bass fingerlings; total, 79.

Pleasant Valley Hatchery 



To the Forest, Fish and Game Commission: 



The year's work at the Pleasant Valley hatchery has not been all that 

 we hoped for, on account of several drawbacks. First, our stock of eggs 

 was small, compared with previous years. Only a small amount of lake 

 trout eggs were secured, these being taken from Lake Keuka. Then our 

 brook trout fry suffered more than usual from the gill disease and, most 

 of all, our stock fish, especially the brook trout, were affected with the tumor 

 disease which we are advised has broken out also in several government 

 stations. Several remedies were tried and the last shows the best results, 

 namely, putting the fish into a brook where a good current of water is to be 

 had and giving no food. Many theories are advanced as to the cause of this 

 trouble but nothing definite seems to be known. This is a matter for all 

 concerned in the propagation of fish to study. The trouble may come from
