ROUND WHITEFISH 



Pro.sopiuni cylindraceus (Pallas) 



Round whitefish are distributed from New England west through 

 the Great Lakes to Alaska. No game fish, round whitefish are important 

 to our fisheries as a forage. Lake trout in particular are frequently 

 taken with round whitefish in their stomachs. Small aquatic organisms 

 in turn make up the food of this whitefish. 



The spawning season runs from October to December in the shal- 

 low waters of stream mouths. Young round whitefish possess three rows 

 of dusky spots along the sides.
