predictor of female maturity in this study and a mean 
age-at-maturity (A 50 , 7 years) was established for female 
arrowtooth flounder that will allow for the development 
of an improved stock management model. The model 
should provide more reliable estimates of arrowtooth 
flounder abundance in the Gulf of Alaska as well as 
the Bering Sea. This study also documented the total 
body length (L 460 mm) at which 50% of the females are 
mature in the Gulf of Alaska — an estimate that did not 
differ significantly from a 1993-based estimate.
