Hobson et al.: Predation on first-year Sebastes spp 
301 
Although a measure based on recruits entering the fish- 
ery would more accurately define the resource, there have 
been no effective methods developed to determine abun- 
dance at that point. And even if available, the lateness 
of such a measure would limit its effectiveness. An as- 
sessment made at the end of the first summer based on 
direct visual counts by underwater observers, as described 
above, is an effective compromise. The YOY are readily 
counted, much of the postsettlement mortality is included, 
and there is time to use the results in planning manage- 
ment strategy.
