Abstract:
:Plasma vitellogenin and related parameters in the killifish Fundulus heteroclitus were measured at selected sites in the Chesapeake Bay. In males, vitellogenin was above the detection limit 14% of the time, and detections did not differ between sites or seasons. Few differences in plasma vitellogenin levels were found between sites during fall in either male or female F. heteroclitus, the time of natural gonadal regression for this species. There was some variation in the ratio of male to female F. heteroclitus, but was not consistent at most sites. Significant negative correlations were found between reported sediment polycyclic aromatic hydrocarbons (PAHs) and GSI, and PAHs and plasma vitellogenin in females in both Spring 1999 and Spring 2000. Gonadal anomalies in F. heteroclitus included slight reductions in certain tissue types. Overall, reproductive endocrine disruption in the killifish F. heteroclitus at the sites sampled in the Chesapeake Bay appeared somewhat minimal.
