What you see in Kersti Muul‘s photo above aren’t bubbles – they’re herring eggs. And their presence is “a big deal,” we’re hearing from her and from “Diver Laura” James tonight. This area is not a documented Puget Sound spawning ground for herring (this infosheet shows the areas that are), so wildlife watchers have nothing to compare it to – but they’re seeing not only the eggs, but also sea lions offshore feasting on the herring (that explains the second photo in this gallery we published early today, as well as other reports of sea-lion groups offshore last weekend), and gulls with beakfuls of herring:
Kersti says, “I encourage people to be on the lookout for it as well, and to tread lightly right now in the nearshore during these very low tides!” She has been in contact with the state Fish and Wildlife Department, as has Diver Laura, who says WDFW will be sending somebody up for a firsthand look. Here’s a closeup photo she shared tonight:
Because this isn’t a historic spawning ground, the state hasn’t historically sampled here, so, she explains, “we simply have zero data,” and it’s not known yet whether this is a return or a cycle. Both point out that the significance of this might also be future effects on construction and other activities on the shore, since without documentation of this previously, there are no rules/laws about habitat protection.
P.S. Here’s more background information about herring in Puget Sound. Followups to come!
