Table 3.— Food habits of male and female Oligocottus snyderi collected during the 

 Upwelling period. Values shown for each prey type are total weight ingested, percent 

 of total prey weight, and frequency of occurrence (FO).

by the O-i- and l-i- age classes observed by Moring 

 (1981) were similar to those displayed by the Dillon 

 Beach age O-i- and 1+ classes; however, Moring 

 observed age 2+ individuals of up to 101 mm SL. 

 Nakamura (1976a, b) also reported collecting 0. 

 snyderi >80 mm SL at Port Renfrew, British Colum- 

 bia. These results indicate that 0. snyderi may have 

 a longer lifespan at more northerly locations. The 



scarcity of individuals >70 mm SL at Dillon Beach 

 probably did not result from repeated sampling 

 because such large individuals were absent from the 

 initial samples and from collections made in 

 previously unsampled pools near the study site in 

 August 1979, December 1979, and April 1980. There 

 was no discernable pattern in sex-ratio deviations 

 from unity observed in four 1979 collections, which
