Figure L— Length-frequency distributions for 

 Oligocottus snyderi. Males and females are 

 separated in the 1979 collections, with females 

 shown below the axis. Arrows indicate divisions 

 between year classes + and 1 + , and broken lines 

 designate limits for inclusion in cohort mean SL 

 calculations (January, June, July, and August 

 1979). The 1980 and 1981 collections are included 

 for comparison, but the sexes are not shown 

 separately.
