fecundity estimates, which correspond to the 

 "pre-fertilized" fecundity of Raitt and Hall 

 (1967). The distribution of fish lengths for the 

 fecundity samples is shown in Figure 1. 



Mean diameter of the preserved, unfertilized 

 oocytes was 0.814 mm and individual means 

 ranged from 0.634 to 0.954 mm. The mean num- 

 ber of oocyte subsamples counted was 4.1 and 

 ranged from 3 to 6. Coefficients of variation of 

 the counts ranged from 0.6 to 10.2% with a mean 

 of 4.6%. As expected, fecundity increased with 

 increasing length, with estimates ranging from 

 95,375 oocytes at 33 cm FL to 1,113,000 oocytes at 

 52 cm FL (Fig. 2). Data were fit with linear re- 

 gressions as used by Gunderson et al. (1980) and 

 with power functions frequently used in fecun- 

 dity-length relationships (Bagenal and Braum 

 1968; Raitt and Hall 1967). Although both equa- 

 tions were highly significant, the linear regres- 

 sion provided a slightly better fit to the data but 

 may underestimate fecundity at lengths below 

 about 36 cm FL. Only rarely, however, are fe- 

 males smaller than 35 cm FL sexually mature 

 (Barss and Echeverria footnote 3). A linear rela- 

 tionship was also used to describe the weight- 

 fecundity relationship (Fig. 3). The fitted equa- 

 tions are as follows:

 fork length (cm). Triangles represent mean values for fecun- 

 dity from the present study and the line represents the fitted 

 curve through these points. Squares represent mean values of 

 fecundity from Phillips (1964) with lengths converted to the 

 nearest cm FL. The relationship from the present study is sig- 

 nificantly different from that of Phillips (analysis of covari- 

 ance, P<0.01).

 Fecundity of S. entomelas is thus relatively high 

 within the genus Sebastes, with values similar to
