If you are concerned about the latest proposals to bring net pen aquaculture to the Strait of Juan de Fuca (5 miles west of Port Angeles), or are concerned and unclear about the current standoff by the Department of Ecology and the Jefferson County Commissioners over allowing in water net pen aquaculture in Jefferson County (through the Shoreline Master Program updated), then you should take the time to listen to this lecture (it runs over an hour in total). It is, to be sure, one of the most comprehensive overviews of the possible negative impact of net pens I’ve ever heard, and is based on research done just north of us, in BC. While Dr. Dill clearly states that there are variations of environment between there and here, the issues are ones that we may face if they are allowed here. Then again, as pointed out in the Q&A session at the end, by the manager of one of the net pen companies south of Bainbridge Island, some of these issues have not shown up (though that comment was not based on peer review independent scientific research, but on experiential information. It was not independently verified and simply is presented as the point of view of the farm manager).
Dr.Dill is one of the foremost researchers on sea lice, and has a lot to say about the “possible” negative impacts of net pen aquaculture based on years of scientific, peer reviewed, published work. He was brought to lecture in Port Angeles last week, by a consortium of environmental groups concerned about the proposals for net pen aquaculture in Jefferson and Clallam counties lately. The event was sponsored by the Coastal Watershed Institute, Wild Salmon Center, Sierra Club Activist Network, and Olympic Peninsula Chapter Surfrider Foundation.
His talk was titled:
Evolutionary & Behavioral Ecology and Earth2Ocean Research Groups of Simon Fraser University, British Columbia, Canada presented:
POTENTIAL NEGATIVE ECOLOGICAL CONSEQUENCES OF OPEN NET PEN SALMON AQUACULTURE: LESSONS FROM BRITISH COLUMBIA
The discussion included:
• The impacts that salmon farms can have on wild salmon stocks
• Recent research on sea lice and other pathogens.
• How the iconic Fraser River sockeye salmon have been put at risk by salmon aquaculture.
• Degradation of the bottom communities below the farms.
• Pollution, by-catch of other fish species, escapes, and inadvertent or intentional reduction of marine mammal populations.
• New potential open pen aquaculture projects near Port Angeles.
The introduction by Anne did not have a microphone so it’s a bit noisy. Dr. Dill did have a microphone on, so it sounds better when you get to him speaking. The video was published in two parts. A shorter 10+ minutes to allow you to get the gist of the presentation, and the rest of the presentation in Part 2. The audio podcast is presented in it’s entirety.

I am adding the links above to the “Educational” links on the left hand side of the front page. You can always find it there if you need to refer to it later. Thanks to Dr. Dill for allowing the sponsoring groups to videotape the presentation, and offer it to those who were unable to make it to the discussion.
