Hood Canal is a fjord forming the western lobe, and one of the FOUR main basins of Puget Sound. However there are various definitions of the extent and boundaries of Puget Sound. The USGS defines Puget Sound as all the waters south of three entrances — the main entrance at Admiralty Inlet being a line between Point Wilson, on the Olympic Peninsula, and Point Partridge, on Whidbey Island; a second entrance at Deception Pass being a line from West Point, on Whidbey Island, to Deception Island and Rosario Head, on Fidalgo Island; and a third entrance at the south end of the Swinomish Channel, which connects Skagit Bay and Padilla Bay. UNDER THIS DEFINITION PUGET SOUND INCLUDES HOOD CANAL. But I can see why people argue the point.

Friends, I have over 1000' feet of beach on the southern end of the canal. In the family for 80 years. We picked about 25k during oyster harvesting last year.

This subjects story - which is backed by very solid scientific research - has me very concerned and should have anyone who enjoys Puget Sound/Hood Canal oysters. It also concerns the indusry (ie: JOBS) which help keep the Puget Sound waters clean. If this continues (and I supect it will) we will see many sets of young oysters fail to naturally spawn. This will effect the industry but it will also effect some fishing and the environment overall.

MANY seabirds and fish thrive over olderr oyster beds, which are a huge benefit to the ecosystem for small fish (Juvenile salmon), and Sea Run trout. Older beds are extremely rich in biomass supporting Loons, grebes, mergansers, scoters, varous fish large and small. This in turns helps raccoons, eagles, seals and other larger creatures we would never want to live without.

Having said all that, the Pacific Oyster is a non native oyster, but its been here for over 150 years and can be considered an invasive native at this stage. I rarely locate Olympic Oysters unless I find a few small ones on a rock here and there. Most native oyster reefs in the world have been wiped out. Farmed Oysters (via natural sets or non natural) generate over 100 million dollars to Washington each year.

Oysters dont usually grow on points much in my experience but they tend to cluster in Bays and get washed around points due to storms, strong tides etc. All locations are a little unique and it often depends on the beach type (rocky/sandy/muddy) and tide flow plus storms effect.

I sure hope we dont see an end to the Hood Canal Osters, they are truly amazing and delicious! Great for local income and a source of pride for Western Washingtonians.
