Spawning in the New Year

Two new spawning events were observed during CDFW spawn surveys yesterday. Keil Cove along the Marin County shoreline had recently deposited herring eggs on eelgrass.

There was also a large school detected, which was presumably herring in the area of Racoon Straights and Sausalito. A second spawn was also observed along the rock jetty just outside the Coyote Point Marina in San Mateo County. A trace amount of eggs were deposited on the rocky riprap and attached vegetation.

The CDFW research trawl vessel also metered and sampled a large herring school off of Hunters Point, just south of San Francisco. CDFW staff will continue to monitor the area for what is likely to be more spawning activity. Check back soon for updates.

The Richardson Bay spawn is primarily centered in the the anchorage east of Schoonmaker Point. The Point Richmond spawn is located south of the harbor entrance channel outside the rock jetty. This event had a significant amount of marine mammal and bird activity during the early afternoon today. Staff will continue to monitor both spawn locations into next week. Happy Holidays!

since the Alameda spawn earlier this month. CDFW scientific divers have however been busy conducting annual SCUBA surveys to determine vegetation types and densities for areas where herring typically spawn. Last week’s dive sites included Richardson Bay and Belvedere Cove. Eelgrass and red algae are commonly encountered in these locations and ideal spawning substrate for herring. You can check out this video of a dive at Belvedere Cove. The clip shows the divers perspective as they descend the marker line and assess the type and density of vegetation in the sample area. It is murky but it does give you a view into the underwater world of San Francisco Bay.

Bird Activity- Alameda: Credit CDFW

During routine spawn patrol this morning, bird activity was noted near Ballena Bay on the south-side of Alameda Island. The sparse sub-tidal vegetation in the area yielded a few eggs that were very recently spawned. Staff will continue to monitor and sample the area over the next couple of days to see if any additional spawning occurs. More season updates will be forthcoming, please check back soon.

Pacific Herring FMP Peer Review Webinar – October 9, 2018

The California Department of Fish and Wildlife is currently developing a Pacific Herring Fishery Management Plan. California Ocean Science Trust, with support from the Ocean Protection Council, and at the request of the California Department of Fish and Wildlife and the Fish and Game Commission, coordinated an external, independent peer review of the scientific and technical merits of the proposed management strategy within the Fishery Management Plan.

The reviewers have completed their review and are pleased to announce the release of the final peer review report,  Scientific review of the draft Fishery Management
Plan for Pacific herring (
Clupea pallasii).
