LONGNOSE SUCKER 



Catostomus catostomus (Forster) 



The longnose sucker and the white sucker are similar in appear- 

 ance and it is unlikely that they are considered as different fishes by 

 most people. 



The longnose is taken in colder lakes and at greater depths. White 

 suckers are not so specific in habitat requirements and are probably 

 more abundant for this reason. Maine lake studies report the longnose 

 as living pelagically in the deeper waters. Lake Superior commercial 

 fishermen take this species at depths of 600 feet. Spawning migrations 

 coincide in general with those of the white sucker. 



These two species of suckers, the white and longnose, were found 

 to make up one of the principal foods of lake trout over five pounds. 



Average lengths of longnose suckers taken from Maine waters 

 range between 8 and 10 inches in total length, although several speci- 

 mens have been taken measuring up to 17.3 inches and weighing 2 

 pounds.
