Growth 



Silvergray rockfish age estimates have not been vali- 

 dated as they have been for other rockfish (Bennett et 

 al., 1982; Culver, 1987; Leaman and Nagtegaal, 1987; 

 Andrews et al. 2002; Kerr et al. 2004); however, there 

 is evidence of a modal progression in the year classes 

 (Stanley and Kronlund, 2000). 



Our estimated growth rates were similar to those 

 reported by Archibald et al. (1981), who used a small 

 subset of the current data. The maximum recorded 

 size of 73 cm for silvergray rockfish is larger than that 

 for most rockfish but smaller than that reported for 

 the largest rockfishes, such as yelloweye rockfish (S. 

 ruberrimus), cowcod {S. levis), shortraker (S. borealis), 

 and bocaccio (S. paucispinis), all of which can exceed 

 91 cm (Haldorson and Love, 1991). The growth rate of 

 silvergray rockfish is similar to that of other rockfishes 

 (Haldorson and Love, 1991), and weight at length was
