Comparison of observed and estimated length frequencies of Kodiak red king crab catches modeled 

 with weighting factor A = 1 and with a constant M of 0.3, 0.4, and 0.5. 



Similar to Bristol Bay RKC, there was very little 

 difference in length compositions of recruits among 

 all fits (Fig. 10). The difference in molting probabili- 

 ties was generally less than 10% between any two 



fits for any given length class (Fig. 10) and was less 

 than 2% among most fits for a given length class. 

 Molting probabilities for the first group of years were 

 much higher than the second group.
