Length and age data are available for 17 of 

 the 19 females (Table 1). One attained an es- 

 timated age of 18 years, having been at liberty 

 for 10 years after being tagged. If these 17 

 females molted once each year, their growth 

 per molt ranged from 3.1 to 7.2 mm (length) ; 

 the average increment was 4.7 mm. This aver- 

 age value is similar to other reported annual 

 growth increments for female king crabs in 

 Alaska waters— 4.4 mm (Powell, 1967), 3.9 mm 

 (Gray, 1963), 5.0 mm (Bright, Durham, and 

 Knudsen, 1960), and 4.0 mm (Sakuda, 1959).
