Dead fish collect along the San Francisco Bay amid rare algae bloom

Thousands of fish are dying and washing ashore around Oakland’s Lake Merritt and other parts of the San Francisco Bay.

What’s happening: Environmental groups believe the algae bloom — first spotted near Alameda in late July — is to blame. The Bay’s water has since turned brownish-red in color.

  • SF Baykeeper says that decomposition of the algae can “deplete oxygen in shallow areas, which can result in injury to or death of fish or other wildlife.”
