Stars represent samples with a majority of males. Circles represent samples with a majority of females. Hatched areas indicate strong male or female dominance in samples. Cruise designations ( 75A1, 69A6) refer to the chronology of the cruise (first and sixth) on the research vessel ALASKA (A) during a calendar year (1975 and 1969). ly female for the first three cruise periods. In the Channel Islands-Port Hueneme area the sex ratio consistenty favored females. During "April" and "May-June" cruises, males were dominant in the vicinity of Santa Monica Bay. During the "October-November" cruises, there was a breakdown of this pattern with few areas showing large differences in sex ratios. The observed female distribution in samples of 25 fish for "October-Novem- ber" and "February-April" were radically different (Figure 6). For the "Febru- ary-April" period, 34% of the samples fell beyond the 2%
