Adams and Hankinson. — Oneida Lake Fisheries 163 



Davison and Coville conduct a gross business of about 

 $15,000 per year in frogs alone. One customer bought 

 between June 1, 1915, and March 1, 1916, $1,687.50 worth 

 of frogs' legs. When sold per hundred, live weight, large 

 and small, the price ranges from 30 cents to $1.50, or 

 averages $1.05. The legs sell per pound, large and small, 

 from 10 to 50 cents and average 35 cents per pound. An 

 expert can dress between 15 and 16 hundred frogs per 

 hour, but an average rate is about 1,000 per hour. 



ANNOTATED LIST. 



This list includes the species of fish, and the lamprey, 

 known to occur in Oneida Lake. There are several col- 

 lections which yet await critical examination, which will 

 add several species to this list. Most of the data for 

 this list is based on collections made by the authors dur- 

 ing ten days of field work done between August 31, 1915, 

 and September 10, 1915. To these have been added other 

 records from collections made by the senior author before 

 and since the joint collecting. A few published records 

 have been used. The shallow water of the lake has been 

 carefully examined from Constantia to Brewerton on the 

 north shore, and from Brewerton to the mouth of Chit- 

 tenango Creek on the south shore. 



The brief annotations are necessarily general and the 

 list simply shows our progress in finding the species 

 present, but it will give a fair idea of the fish fauna of 

 the lake, and some idea of its important fisheries. 



Petromyzon marinus unicolor (De Kay), Lake Lamprey. 



Evidently very abundant in the lake. They were fre- 

 quently found on the under sides of our boats, to which 

 they would attach themselves while the boat was in 

 motion, and when the boat would stop they would release 

 themselves. The many dead fish that we found in the 

 lake frequently had lamprey marks upon them. Two 

 cases were heard of lampreys attaching themselves to 

 bathers, but the only harm done was the fright they
