The longjaw cisco (Coregonus alpenae) was a deep-water
food chains after the introduction of the sea lamprey.[4]
: 39942, 39943
The systematics of the group of fishes called "ciscoes" is complicated and scientists now generally believe that the longjaw cisco was not a separate species, but a distinctive population of large-bodied individuals of shortjaw cisco (Coregonus zenithicus).[citation needed]
The deepwater cisco fishery caught longjaw ciscoes and sold them as "smoked herring". The commercial catch peaked around the 1930s when about one-third of the catch of ciscoes was this species.
No individuals have been reported in commercial fish catches since 1967, and in Ontario the last individual was recorded from Georgian Bay in 1975.
