48, Ictalurus nebulosus (Lesueur), brown bullhead (fig. 38) 



The brown bullhead is common in Lake Superior tributaries. The barrier catches of this 

 species have fluctuated widely from one year to the next. The catch on the Au Train River varied 

 from 4 individuals in 1954 to more than 10,000 in 1959. This wide variation in the catch of brown 

 bullheads has characterized many Lake Superior streams.
