Potential role of contaminants in declines of pelagic organisms in the Upper San Francisco Estuary, California

Principal Investigators:

Erica Fleishman

In late 2004, scientists noted that abundance indices of several pelagic fishes in the upper San Francisco Estuary (delta smelt, age-0 striped bass, longfin smelt, and threadfin shad) had remained unusually low since 2001. Delta smelt is an endemic species listed as threatened under both the California and U.S. Endangered Species Acts. Protection of delta smelt often determines water management actions in the estuary, which supplies drinking water to more than 22 million people and supports a multi-billion dollar agricultural industry. The abundance... more
