and round whitefish (Coregonus cylindraceum) , 

 which are usually deep-water species, would 

 probably have been caught in greater numbers 

 had more deep sets been made(Rawson, 1951), 

 Furthermore, fish larger and smaller than 

 juvenile sockeye salmon were not as likely 



to be caught because of mesh selectivity. All 

 species known to be in the lake were caught in 

 the gill nets with the exception of north- 

 em pike (Esoxlucius) and Artie grayling 

 (Thymallus arcticus), which are both rare.
