              of eating trout eggs and young. Probably most of the trout
eggs con- 
              sumed by sculpins are loose eggs that have not been buried
in the nests. 
              Little evidence is available to show that sculpins limit trout
numbers. In 
              fact, in large, deep lakes sculpins are an important forage
fish for large 
              trout and other predator species. 
                Sometimes a sculpin is used as bait by anglers. 
                From the accounts of sculpin species which follow, it is
evident that life 
              history information for some species is sketchy. W. Van Vliet,
while 
              working in deep water with scuba gear, lost his life in October
1968 as he 
              attempted to unlock the mysteries of spoonhead and deepwater
sculpin 
              ecology and behavior in Heney Lake, Quebec (Delisle and Van
Vliet 
              1968). The sculpins yield their secrets grudgingly-particularly
those 
              species in deep, coldwater habitats.
