Opaque cornea, resulting after death and disintegration of the parasite, is denoted by an arrow. We plotted the length versus weight of eight infected and 85 uninfected fish collected in a single trawl conducted by Scripps Institution of Oceanography, off Point Loma, San Diego. We found that infection with P. cincinnatus did not alter the length and weight of infected fish compared to controls (Fig. 5). The total number of sanddabs captured in trawls off Point Loma (24,382 from 1992-95) was greater than that for Santa Monica Bay (10,096 from 1989-94), and the Palos Verdes shelf (20,749 from 1979-95). However, the fish were gen- erally larger at either Los Angeles site compared to San Diego. Similarly, the most heavily infected sanddabs ranged in size from to cm in Santa Monica Bay (Table 1), to cm off Palos Verdes (Table 2), and from to cm off Point Loma (Table 3). During the course of the study, ovigerous specimens of P. cincinnatus were found infecting several other species of fish. These were: (1) longfin sanddab {Citharichthys xanthostigma)—one specimen from Santa Monica Bay and two specimens from Point Loma; (2) pink seaperch (Zalembius rosaceus), collected off Point Loma at a depth of 100 m by Scripps Institution of Oceanography; (3) bay goby (Lepidogobius lepidus), collected from Santa Monica Bay at 100 m. In addition to harboring an ovigerous parasite, two post-mated juvenile female spec- imens were found
