The first reports of dead white sturgeon, apparently resulting from a red tide algae bloom and oxygen depletion on San Francisco Bay, began to come in on August 4, when five white dead sturgeon off Point Molate were reported by naturalist Damon Tighe in a Facebook post. Fortunately, Tighe noted on August 8 that the bay’s recent Heterosigma algae bloom “appears to be subsiding.” … Last summer, many thousands of fish, including hundreds of white sturgeon and some endangered green sturgeon, perished as a similar bloom spread throughout the bay. A total of 13 dead white sturgeon have been reported to the inaturalist.org website to date. Seven bat rays, 6 striped bass, 4 Dungeness crab, 2 thornback guitarfish and 2 shovel nose guitarfish have also been reported.
