Annual mean fork length of striped bass caught in four areas of the western Sacra- mento-San Joaquin Estuary. Anglers on private boats consistently caught larger fish than anglers on charter boats (t = , P < ; Table 4). The overall difference was due to a consist- ent difference in San Pablo Bay and Carquinez Strait-Suisun Bay (Figure 6). In the Pacific Ocean, bass caught on private boats and charter boats were of similar size in most years; in San Francisco Bay, bass caught on private boats were larger through 1975 and smaller thereafter. The average bass caught from shore appeared to be intermediate in size between those caught on the two types of boats, although samples of shore caught fish were small and lengths were rather variable (Table 4). From 1969 to 1979, almost two-thirds of the censused catch was comprised of 3, 4, and 5 year old bass (Figure 7). Overall, 4-year-old fish were the most abundant age group in the catch and each successively older age group became less abundant. Two-year-old bass accounted for less than 1% of the catch. Within individual years, the age composition often deviated from the average pattern (Figure 7). Age 3 bass were well underrepresented in 1969 (11%), 1973 (10%), and 1977 ( <8%) compared to the 11 year average of about 21%. Hence, other age classes were relatively more numerous in these years. In 1969, age 7 and older bass formed 39% of the catch (11 year average: 22%). The 1973 catch had a high proportion of ages 4-6 (68% compared to the 56% average). In 1977, 5-8 year old bass accounted for 71% of the catch (average of 46%).. Please note that these images are extracted from scanned page images that
