King Salmon Vanish

Posted by Scott A. On August - 17 - 2009

As the weekend rolled to an end and the inevitable Monday workday loom overhead, I moseyed on to the bedroom and turned on the radio. Expecting to encounter a little paranormal lullaby, I was incredibly surprised to find the guest host of Coast To Coast AM, George Knapp, tackling the overfishing crisis.  In his interviews with Rupert Murray (The End of the Line) and Rick Moonen (RM Seafood), George brought this important topic of conservation concern to an international audience.  Since Coast to Coast AM is broadcast on over 500 United States affiliates alone, I was elated  to hear the notion of sustainable seafood practices being promoted to millions and perhaps recruiting some listeners to ultimately make informed and responsible meal decisions.

 And sprinkled throughout their conversations was a discussion, or warning if you will, about a vanishing act recently perpetrated by Alaskan King salmon.  Well, after a little online digging I managed to come up with an AP report (Aug. 2, 2009) on CBS News describing the failure of king salmon to return to a number of Alaskan rivers…again.King Salmon

“One Alaska river after another has been closed to king fishing this summer because significant numbers of fish failed to return to spawn. The dismally weak return follows weak runs last summer and poor runs in 2007, which also resulted in emergency fishing closures.” AP

And as the salmon continue to vanish from our waters year after year, we are left speculating whether the problem is ocean currents, food availability, bycatch, aquaculture, or overfishing.  Yet over the last decade, ” the incidental number of king salmon caught has skyrocketed, reaching over 120,000 kings in 2007.” AP

Hmmm!  Perhaps a connection?  Instead of embarking on another version of the blame game and debating whether (or to what degree) the lack of salmon returns is caused by natural phenomena, such as changing ocean currents, river conditions or available prey, or human activities, we need to institute a little fisheries management tough love. 

For in the end bycatch may not be the only culprit, but as opposed to the actions of Mother Nature, it is the factor that we can definitely control.  And of the 120,000 kings killed in pollock trawl nets in 2007, an estimated 78,000 adults would have returned to the rivers of western Alaska.

Saving salmon with bubbles and strobe lights

Posted by Scott A. On June - 10 - 2009

The California Department of Water Resources is experimenting with a new way to save salmon in the delta.  “Preliminary results show that an experimental, non-physical fish barrier is working to help keep young Chinook salmon and steelhead in a more direct path to the ocean and away from agricultural diversion and the state and federal pumping plants. The bubble curtain barrier project combines acoustics and a strobe-lit sheet of bubbles to create an underwater wall of light and sound at frequencies that repel juvenile Chinook salmon.”

Salmon Bailout

Chinook SalmonThe S.F. Chronicle broke a story today in which the headline exclaims that the ‘U.S. extends disaster order for chinook salmon’, and I must say it is about time!  The writing on the wall has graced our oceans and rivers for the past few years so I think it is appropriate to start this off with a quote from JournOwl (‘Salmon by the numbers’) as it attests to the fact that chinook salmon are in trouble:

“At one time California’s Central Valley witnessed the return of adult Chinook salmon 3/4 of a million strong. By 2007, the returning population making the trek from the Pacific Ocean through the San Francisco Bay and spawning in the Sacramento River had declined to 90,000. And with the season ending in 2008, the numbers had managed to only reach 8.8% of their former number. Did I mention the Chinook salmon population of 750,000 I am referring to was a mere 6 years ago in 2002?”
