Percent of all Microstomus pacificus collected on the Palos Verdes shelf from 1971 through 1983 with epidermal tumors by 10 mm size class. Among the sample of 100 tumorous M. pacificus collected in 1971 and 1972, there was no correlation between the number of tumors per fish and fish size (r= ,.10</'<.20) (Figure 4). The fish ranged from 61 to 208 mm SL with a mode between 100 and 120 mm; were larger than 150 mm. There was a significant correlation between tumor size and fish size (r = .643, P<.001) (Figure 5). Of the individuals with only one tumor (n = 46), had it on the eyed side, had it on the blind side, and had it extend onto both sides. Of the individuals with more than one tumor (n = 54), had tumors on both sides, had tumors only on the eyed side, had tumors only on the blind side, and had at least one tumor extending onto both sides. Disregarding individuals with tumors on both sides, the ratio of fish with tumors on the eyed side to fish with tumors on the blind side was not significantly different from 1:1 (x' = , n = 63, .05<). There were significant differences among the inter- cepts (F = , P < .001) however, a Newman-Keuls multiple range test could not detect which transects were significantly different. The prevalence of tumor- ous individuals was significantly higher (x^ = , P< .001) at transects closer to the outfall (Tl, T4, and T5) than at the transect farthest away (TO) (Figure 6)..
