gizzard shad ; black sucker ; red-horse ; black-nosed minnow ; 

 channel cat ; sauger ; sheepsheacl. The white bass is similarly 

 reported from both Cayuga and Seneca. The brown trout has also 

 been rarely taken in at least four of the lakes and the landlocked 

 salmon has been reported by the Skaneateles fishermen.* This 

 brings the Finger lakes list to 69 species not counting those which 

 inhabit the tributary streams. 



Distribution of Finger Lakes Fishes. — The lamprey was 

 found only in Cayuga and Seneca lakes and few specimens were 

 taken, but at least 90 per cent of the trout taken in these lakes 

 showed scars, where they had been previously attacked by lampreys. 

 In many cases the wounds were fresh. In Seneca lake it was very 

 evident that the lampreys were more abundant toward the head of 

 the lake, as was expected since they are known to breed in Catherine 

 creek and its tributaries, but not in the other streams. Over 90 

 per cent of the trout taken at Lamereaux landing had from one to 

 seven lamprey scars each, while of those taken farther down the 

 lake near Reeder's creek only 33 per cent showed scars. The Rev. 

 C. J. Clausen, who has been for many years a trout fisherman on 

 Canandaigua lake, reports that he has taken several trout with 

 lamprey scars and has seen a few lampreys there within the last 

 thirty years. But this parasite if now present in Canandaigua lake 

 must be very scarce. 



Alewives are extremely abundant in Seneca, Cayuga and Keuka
