Eelgrass and herring eggs: CDFW

Weekend reports indicated an increase in bird activity around the area and a check of the eelgrass bed yielded a few herring eggs. Small numbers of birds remained but based on sampling of the subtidal areas, the spawn was relatively small in size. Stay tuned for more updates.

Richardson Bay Spawn Report

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.

Spawning also occurred on the eelgrass beds in this location. Bird activity and cast netting continued throughout the day today as herring moved around the old ferry terminal. Staff will continue to monitor the area to see if any new spawning occurs. Stay tuned for more updates…

At weeks end, a new spawn was beginning at Paradise Cove along the Marin County shoreline. Staff will continue to monitor all areas and sampling to estimate the total herring spawning biomass.
