Scientists release report on Pescadero fish kills

Panel finds data is lacking

Scientists theorize that a lack of oxygen in the water is what’s killing steelhead trout in the Pescadero Lagoon. However, their recently released report concludes that more data is needed before specific solutions can be recommended.

The report comes more than three years after an independent science panel convened to provide expertise in support of possible management and restoration decisions for the lagoon and marsh. The formation of the panel, which worked for free, followed years of annual fish kills in the estuary. These mortality events have occurred in late fall, when the return of rainfall causes the lagoon to overflow, rupturing the sandbar blocking the marsh from the ocean. Dead fish have washed onshore following these events.
