food. Recuitment and numerical abundances within 

 this assemblage also were strongly correlated with 

 productivity (Grossman 1982). Oligocottus snyderi 

 possesses a variety of adaptations (ag., rapid matura- 

 tion, high female reproductive effort, utilization of 

 an abundant prey not widely consumed by other 

 assemblage members) which probably are responsi- 

 ble for its numerical dominance in a fluctuating 

 environment.
