It was yet another quiet week on San Francisco Bay. No new herring spawns were reported or observed for this weeks survey period. Staff did follow up on a spawn report near Blackie’s Pasture from the prior week but the event was likely an isolated “trace spawn.” The CDFW research vessel caught a small sample of maturing Pacific herring as well as Northern anchovy and American Shad in the North Bay this past week. As of Friday morning a small herring school was holding in deep water off Tiburon Peninsula. For now we wait until more fish arrive or the holding fish spawn. Note: The Pacific herring commercial gill net fishery opens today January 1, 2017 at 5:00pm.
