Wild Fish v. Hatchery Fish: When Is Enough Data Captured to Convince

“Since the mid-1970s, large increases in hatchery programs in the U.S., Canada, Russia and Japan have released billions of fish into the water. And the increasing global demand for salmon has resulted in calls to further expand hatchery production, especially in Russia and Alaska. In a 2010 open letter to Alaska hatcheries, seafood processors proposed increasing pink salmon hatchery returns by 25%-115% over the next five years. Similarly, Russian hatchery managers stated in 2010 that Russia is planning to build 23 new hatcheries that would increase the country’s hatchery production by 66% or 680 million fish.

“The scale and magnitude of our current hatchery production system is enormous,” says Rand. “Five billion juvenile salmon are released each year worldwide, and the prospect of additional increases in hatchery production is worrisome for the long-term survival of wild salmon.” (more at Science Blog)

HATCHERY FISH ‘DOMESTICATION’

JAY NICHOLAS HAS SOME GREAT INFO 

This a very complex issue for this C Average Student. Dams, Irrigation, Logging, Hatcheries, Commercial Fishing, Pollution, oh and Sea Lions, on and on contributing factors go. And, the propensity is to substitute one man made management style over the top of the previous one. We mucked it up and the mean time, the Put ‘n Take Crowd wants their damn fish! I am glad others are taking on this puzzle and that they put it in terms I can understand…Cliff Notes so to speak.

All the good intentions aside, it does come down to prior investments, jobs, business versus a probable crisis in maintaining/restoring the original wild strains. As much as everyone readily paints business interests as inherently bad and the problem, I at first will always point to government management or mismanagement as a greater culprit in messing things up…then poor stewardship by businesses…and the oblivious ‘I want mine’ by the ‘put in take’ crowd helps perpetuate the whole mess. 

While it feels good to quote some Native American slogan about preserving some resource, I wonder how Oregon and Washington…two states that have had overwhelming Democrat power bases for decades….two very liberal/progressive states…two very eco conscious states have made such a mess of the fisheries. All those Democrat Governors have been silent and void of leadership on these issues. Of course, I’m only a C Student…so what do I know?

“Hatcheries Suck” by Steven Hawley

H/t to Horatio Nailknot/FB in pointing me to this pointed piece about man’s meddlesome ways with Wild Fish via hatcheries and cherry-picked science:

“For reasons that have little to do with biological health, or even sanity, the Obama Administration and key members of Congress think this is a swell idea. Hatcheries suck because they’ve masked a staggering loss of biological diversity and abundance. With a century of hatchery experimentation in the rearview mirror, nearly everything has been lost for Pacific salmon in the Lower 48, including a grip on reality. Most weeks of salmon season here in the Columbia Basin, it’s possible to track down a forecast from some misguided guide, federal mouthpiece, blogger or outdoor pundit chortling about the “near record returns of kings over Bonneville Dam.” This is so patently false it shouldn’t even qualify as a delusion.” DrakeMag

Best Intentioned Management vs. Wild Fish

“We measured lifetime reproductive success of the first two generations of steelhead trout that were reared in captivity and bred in the wild after they were released. By reconstructing a three‐generation pedigree with microsatellite markers, we show that genetic effects of domestication reduce subsequent reproductive capabilities by 40% per captive‐reared generation when fish are moved to natural environments. These results suggest that even a few generations of domestication may have negative effects on natural reproduction in the wild and that the repeated use of captive‐reared parents to supplement wild populations should be carefully reconsidered.”   Hatchery Impact on Wild Fish via Native Fish Society  

Tweaking them, counting them, milking them, dumping them, tagging them, 'managing' them.

Sandy River (Take Action for What Remains)

Trout Unlimited Chapter 678 McKenzie Upper Willamette put out some info re the state of the Sandy River (while announcing a club event). The facts speak for themselves and beg action.

Call on ODFW to restore Sandy River salmon and steelhead.

The Sandy River flows just 20 miles from downtown Portland and has the potential to be one of the healthiest suburban salmon and steelhead rivers in the world. Over the past decade $75 million has been donated towards Sandy River habitat restoration, yet the Oregon Department of Fish and Wildlife continues to resist any reductions in their Sandy hatchery programs. This is extremely detrimental to wild fish.

Runs of salmon and steelhead on the Sandy are currently 3-10% of their historic abundance, and continuing to decline year after year. Much of this decline can be linked to an unaccountable hatchery program. In a recent Portland Tribune article, ODFW District Biologist Todd Alsbury said that reducing the Sandy River hatchery program is a last resort.The ODFW has known for decades that hatchery fish reduce the fitness and long term abundance of wild fish, yet they have demonstrated that they are more interested in protecting their hatcheries than in protecting our wild fish. If future generations are to ever glimpse a spawning salmon, this must change.

Sandy River fall chinook, spring chinook, coho and winter steelhead are currently listed under the Endangered Species Act, and chum salmon have gone extinct.

As a supporter of Oregon’s native fish, take action here: http://tu678.us1.list-manage.com/track/click?u=83b81d79dfb8964f786c6133c&id=0a88b044e7&e=a57a3af76c

This is in my back yard. Ten minutes from my front door. No excuse to not be involved. I just joined the Native Fish Society.
