TABLE 11. — Variation in major prey taxa composition with season for Sebastes pinruger and S. flauidus. F.O. = frequency of occur- 

 rence; % W = percent gravimetric composition; + = a prey category was present but made up O.V'r of the total weight. 



'All collections taken during one cruise All other seasons represent the means of at least two cruises spaced a minimum of 1 mo apart (Tables 1 and 2 give the 

 exact dates and samples collected on each cruise).
