However, station C3, which replaced stations C4 and C5, exhibited the highest prevalence () of any of the stations. This was attributable to an increase in prevalence that occurred primarily during the summer quarter (). Prevalence at stations CI and C9A dropped from pre- vious years ( and , respectively). On the Palos Verdes shelf (Fig. 11), and of the sanddabs collected at stations T4-137 and T5-137 were infected with P. cincinnatus, respectively. About 2% of the sanddabs collected at stations T5-61, TO-61, and TO-137 were infected, and roughly of the sanddabs at stations Tl-61 and T4-61 harbored the parasite. Station Tl-137 had the lowest prevalence (). In San Diego prior to 1995, station SD-13, located approximately midway between the discharge site and the northernmost station, demonstrated the highest prevalence (). SD-12, positioned offshore to the north leg of the Y-shaped discharge pipe, showed a prevalence of The lowest prevalences occurred at SD-14 () and SD-7 (), the most northern and southern stations from the outfall site. However, in 1995 the distribution and prevalence of P. cincinnatus changed dramatically (Fig. 12). Clearly, the prevalence of P. cincin- natus was highest at all stations in 1995 compared to previous years. In addition, 25 <- 2 P 1 05 â iilL. C1 C4 C5 C6 Z2 STATION C9 C9A Fig. 10.
