Thriving Oceans

The California Department of Water Resources is experimenting with a new way to save salmon in the delta.  “Preliminary results show that an experimental, non-physical fish barrier is working to help keep young Chinook salmon and steelhead in a more direct path to the ocean and away from agricultural diversion and the state and federal pumping plants. The bubble curtain barrier project combines acoustics and a strobe-lit sheet of bubbles to create an underwater wall of light and sound at frequencies that repel juvenile Chinook salmon.”
