Mean monthly densities ( + 95% CI) of young-of-the-year (<80 mm), subadult (80-200 mm), and adult (>200 mm) rockfishes on the two 

 low-relief reefs in central Puget Sound, December 1986-August 1988; YOY surveys December 1986-October 1988. No subadult brown 

 rockfish were observed. 



fish/transect). Small brown rockfish were infrequent- 

 ly (mean 0-0.3 fish/transect) seen on either artificial 

 reef. YOY rockfishes were observed (mean 1.7-63.0 

 fish/transect) only on AR2 during the spring of 1987, 

 and during the following fall, winter, spring, and sum- 

 mer (mean 4.3-80.0 fish/transect). Low densities (mean 



2.0 fish/transect) were observed in the October 1988 

 survey. YOY were never observed on ARl. 



Sand/eelgrass areas had the lowest densities of all 

 habitats sampled; large copper rockfish (mean 5.0 in 

 July 1987, mean 0.7 in August 1988), brown rockfish 

 (mean 1.0, August 1987) and YOY (mean 111.0. July
