San Francisco Bay is experiencing a harmful algal bloom (HAB) of Heterosigma akashiwo, an organism that has caused fish kills in other estuaries. While fish mortality events were not observed during this event’s early stages, fish-kill reports began emerging around August 22, shared by researchers studying the bloom and Bay Area residents.
To assess the HAB event’s impacts on Bay wildlife, documentation of fish mortality is urgently needed over the coming days and weeks. However, Bay size (Area: 1600 mi2; shoreline: >300 mi) makes data-gathering a daunting challenge -- one that calls for an ‘all-hands’ approach.
We are therefore seeking the assistance of Bay Area residents to report dead fish sightings. Please contribute to this regional effort: If you observe dead fish while navigating the Bay’s waters or traversing its shoreline, please share your observations by...
This citizen science project is a collaboration between the SFEI, Baykeeper, and UC Davis fish ecology researchers, supported by the San Francisco Bay Nutrient Management Strategy.
