Another great day of sailing

Dissection Day!

Earlier this month 10 gull chicks just learning how to be Western Gulls in San Francisco Bay were helped by a group of youngsters learning how to be sailors.

The gull chicks had been raised at the International Bird Rescue (IBR) in Fairfield. Brought there as injured or orphaned chicks and after weeks of care, even surgery in at least one case, the birds were old and well enough to be released. The youngsters were sailing students at the Alameda Community Sailing Center’s (ACSC) summer sailing camp, which meets at the Encinal Boat Ramp on the West End.

Dawn Lemoine, an Alameda resident and relatively new volunteer for IBR, was looking for an open patch of beach near the USS Hornet  to release the birds. She had two large animal 

​When ACSC director Emily Zugnoni asked for volunteers, all of the sailing students volunteered. A number of campers carefully carried the crates to the beach where Lemoine opened them. The students had several insightful questions and observations, all of which were discussed after the chicks were released. ​​

Lemoine had been warned that young chicks might be too nervous to... Enjoy the full article here.

And for that, this month has been pretty stellar!

If you’ve been within earshot of the water lately, you might have noticed there’s a big commotion going on. The San Francisco herring spawn is on! For fishermen, nature lovers, and our avian brothers, this is one of those large, planet scale events, and one which you can easily witness in person.

​​The herring spawn offers us a short window to see the wonders of what nature has perfected over thousands of years. And lucky for us, our watery backyard is one of the rare places on the West Coast with just the right conditions needed to host such an event. Each year starting in November, hundreds of millions of Pacific Coast Herring leave the open ocean, swim under our iconic golden gate bridge and take up residence in the bay. Apparently they sort of loiter around for a few weeks, living off of their stored fat, taking in the local sights perhaps—and then all at once, and somewhat randomly, a spawn is triggered. Over a few days, a frenzy of activity occurs! The males rush into shallower waters, spraying their milt and releasing pheromones. This signals the females each of whom lay down about 20,000 very adhesive eggs. The result is a blanket of fish roe that clings to eelgrass, kelp, rocks, pilings and yes, your sailboat’s fine hull. It’s a large, large numbers game, and good thing too because...

On the opposite side of the food web, there are all sorts of animals that find the oil-rich herring and its eggs to be quite the tasty delicacy. Crustaceans, starfish, shorebirds and bottom feeders, feed on the high protein eggs. The spawning schools themselves are under aerial attack by dive-bombing cormorants,  guillemots, gulls and other swimming birds. From under the waves, sea lions, seals, and porpoises engage in some spirited fishing and can be seen surfacing then slipping under water, often with some surprisingly loud breathing. Even whales are known to feed on large schools of herring. True, that’s more in the open ocean than our bay, but it has been known to happen. 

Over all, the chances of surviving to the age of three, are thought to be about 50-50. Unlike salmon though, herring can reproduce each year and barring becoming someone’s dinner, live to the ripe age of ten.

​The future isn’t exactly pretty, but not set in stone either. Commercial fishing and egg harvesting in the bay area is regulated. California Dept. of Fish and Wildlife (CDFW) reports that the SF Bay’s 2016-2017 Pacific herring spawning biomass was estimated at 18,300 tons. For the third year in a row, that is below the historical average 49,400 tons. Why such a dismal turnout? It is believed that the 2015-2016 El Niño event, and 2016 “Warm Blob” produced sub-optimal conditions in the northeast Pacific. Furthermore, snow melt due to 2016’s warmer spring plus a wetter winter, also reduced salinity of the Bay Area, possibly affecting the young larvae. So, yes, this year’s report (expected June) may not turn out to be the best on record, but the population numbers in the past have rebounded pretty dramatically. With one female producing about 20,000 eggs, it’s easy to understand why as Ryan Bartling, a fisheries scientist puts it, “the only predictable thing about herring is that they’re unpredictable.”

As good stewards of the world, we need to make sure the bay stays healthy. Like a nice healthy heart pumping fresh life, driving the cycle. Join us as a volunteer at our next beach clean up perhaps?

To enjoy this limited time spectacle check in with our good friends at the California Department of Fish and Wildlife for reports of active sites. This year Mission Bay, Paradise Cove, Brooks Island Bird Sanctuary (Point Richmond) and even our very own Alameda rockwall have been listed as active spots. The peak is usually mid-January thru February. 
A good rule of thumb is to look for a large number of very squawky birds, diving ducks, snorting pinnipeds, and fishing boats. Oh and no doubt, you’ll hear me and my little herring saying, “here fishy, fishy, fishieee.”

Nothing helps bring out the smiles like a beautifully sunny day, free boat access and some tastey bbq.

​Special thanks to all our volunteers that helped by captaining a boat, or captaining the grill and info desk. Our safety boats motored around our harbor as Sail Cubes, CFJ's and two of our Capri 14.2s gave free boat rides. Lots of excitement in the area with Hobie Cats launching and a Flying Dutchman enjoying the breeze.
