Sharks of the San Francisco Bay
They are the Bay's majestic apex predators, critical to the aquatic food web and leading indicators of the health of the entire Bay ecosystem. Yet, relatively little is known about the eleven species of shark who call the San Francisco Bay home. What is the size, range, and biology of each of these populations? How imperiled are they, and how concerned should we be? Tonight we'll speak with scientists and researchers who are working to enhance our understanding of our resident sharks and the threats they encounter in the Bay's urban setting, including pollution, overfishing and habitat degradation. And we'll begin to address the key question as to whether the data we've gathered so far support the creation of a shark sanctuary in the Bay. What would a sanctuary mean for commercial and recreational fishermen and other marine users? And how would a sanctuary in the Bay contribute to shark conservation efforts worldwide?
