FIGURE 22.12 Reproductive success of English sole from urban and non-urban sites in Puget Sound. Shown in the figure
are (A) the percentage of adult female sole entering vitellogenesis; (B) the percentage of adult female sole successfully
spawning following induction with luteinizing hormone releasing hormone analog; and (C) the percentages of fertile eggs
(solid) and normal larvae (diagonal lines) produced by those females that spawned successfully, following fertilization with
pooled sperm from reference male English sole. The number of animals sampled at each site is indicated in parentheses.
Values significantly different from those at the reference sites (Port Susan for 1985–1987 studies and Colvos Passage for
1994 study) are indicated by asterisks (*). (Data were compiled from Casillas et al., 1991; Collier et al., 1997; Johnson et
al., 1988. Figure is reprinted from Johnson, L.L. et al., J. Sea Res., 39, 125–137, 1998. With permission.)
