Canandaigua lake: The trout is relatively scarce in this lake 

 and the whiteflsh relatively abundant. Pike-perch has been suc- 

 cessfully introduced and is an important fish. The black bass is 

 fairly common on the rocky bottoms which are found along large 

 sections of the lake shore. The perch and pickerel which formerly 

 were found in considerable numbers are small and scarce compared 

 to conditions forty years ago. The burbot is abundant in this lake 

 and in our estimation should be removed. Of course a complete 

 destruction of the burbot is impossible but if the use of set lines 

 baited with worms were encouraged and the value of the burbot for 

 salting and pickling were exploited we believe that its numbers 

 could be materially reduced. The small ciscoes which are native 

 to Canandaigua and the smelts which have been introduced in re- 

 cent years are not sufficiently numerous to feed the trout and we 

 would unhesitatingly recommend the introduction of alewives from 

 Seneca or Keuka lake. 



Keuka lake: This lake is the bright and shining example of 

 what might be accomplished in all these lakes if we could control 

 conditions. There are no lampreys or burbots in the lake ; the 

 alewife is abundant, Bottom food like Pontoporeia and Chironomus 

 is abundant, There are more tributary streams which do not 

 run dry, and furnish a favorable breeding ground for the minnows. 

 There are weed beds near Branchport and Penn Yan which fur- 

 nish satisfactory breeding places for the perch, bullhead and large- 

 mouthed bass. The inlets at Hammondsport and Branchport are
