Me too, buddy. Veeery hungry!

Bon appetite!

Makes sense the homeowners cleaned up and municipalities still let it spew.

I would not consume shellfish pried off of pilings in South Puget Sound, where tidal action isn't that great and some contamination is possible. Hood Canal is another body of water that doesn't flush real well.
However, there are clam and mussel farms near the Straits of Juan de Fuca and the San Juan Islands up North that get lots of ocean water twice daily and produce a fine product.
I wouldn't harvest Dandelions for a salad at dog pee level, either. Cheers.

The article states: “Due to the low adhesion between ice and shell, the smallest underwater flow can therefore wash off the ice again and the scallop does not freeze.”

That clearly says “the scallop does not freeze”. For your point to be accurate, it should state: “the scallop does not become covered with ice.” I believe your interpretation is probably correct and that the scallop likely has a lower freezing point than the water temperature. I was pointing out that the article is poorly written, or should have included more information about the temperature at which the scallop will actually freeze.

Shellfish on piling absorb the creosote they pilings are soaked in. HC flushes over a 7 year period.

Unless Victoria, BC has made a major investment in sewage treatment recently, they dump raw sewage directly into the Straits.
