It was a busy week for CDFW staff tracking herring around San Francisco Bay.
Spawn events were detected in the northern portion of the bay as well as in areas south of San Francisco. Spawning has been occurring on and off for the last week around Candlestick Point and Hunters Point. To the north, a spawn was detected in Richardson Bay in the offshore anchorage. At week’s 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. Check back soon for more updates.
