San Francisco Bay Fund Inventory of Projects
Survey of Endocrine Disruption in Fish Inhabiting Nearshore Wetlands in San Francisco Bay
Organization: University of California, Davis, Bodega Marine Laboratory
2005 Grant Recipient – Sonoma County
Purpose
Many regions of the San Francisco estuary are contaminated with legacy and/or emerging contaminants, many of which are potential endocrine disrupting compounds (EDCs). The Pacific Estuarine Ecosystem Indicator Research consortium (PEEIR) project has previously found reproductive abnormalities in longjaw mudsuckers (Gillichthys mirabilis) associated with sediment contamination at Stege Marsh in San Francisco Bay which is associated with industrial, urban, and agricultural contaminants (http://www-bml.ucdavis.edu/peeir/index.htm). Reproductive abnormalities included the presence of choriogenins (egg shell proteins produced by the liver in response to estrogens) in male/immature fish, and ovotestes (gonads with both testicular and ovarian features). These abnormalities were not observed at China Camp in San Francisco Bay.
The goal of the current survey was to sample additional wetlands (Newark Slough, Triangle Marsh, Sonoma Creek Marsh) for evidence of endocrine disruption in other populations of mudsuckers, and to resample mudsuckers at China Camp and Stege Marsh.
