Richardson Bay Herring Spawn Report, San Francisco Bay

A new herring spawn was detected in the Richardson Bay anchorage (near Sausalito) on Monday this week. Rafts of birds and a few marine mammals marked the spawn area. A herring school could also be seen on the fathometer during the flood tide inside the Sausalito Channel. The spawn itself had fairly light egg coverage but it did cover the middle anchorage zone. CDFW staff will continue spawn surveys through the end of the season so please check back soon for more updates.
