Fishery Bulletin 108(4) 
ics has implications for fisheries management. For 
instance, the design and placement of marine pro- 
tected areas can be augmented to include areas where 
juvenile rockfishes are recruited and grow, increas- 
ing the likelihood of sustained production for those 
rockfish species. Recruitment dynamics also need to 
be considered when conducting surveys of rockfish 
populations early in their life. These surveys can lead 
to enhanced recruitment predictions for the fishery. 
However, without information on the spatial and tem- 
poral occurrence of recruitment, surveys could be 
mistimed in a particular region and lead to biased 
estimates. Results of the present study indicate that 
coastwide recruitment surveys should be conducted 
from south to north to allow for later spawning times 
with increased latitude.
