Study on Coho mortality

[Sitka_Blacktail]

OK that link opens up a download and I opened the downloaded file with windows explorer. Very interesting reading.

While i am open to all reseach on this issue... wasnt the purpose of all these water retention  and run off ponds with cattails supposed to be part of the solution?

It appears to me that several water setting ponds exist for runoff for the airport. God knows every new development in the lat 30 years has them.

Not that i i wouldn't love to find the Silver bullet on the issue because the we could quit flooding good state land for salmon habitat.... That said im some what skeptical. Perhaps its the seals in mass number eating salmon... evenen as far up as Mount Vernon or Burlington....

Well I can tell you Coho are still being caught in the upper Skagit all the way up to the Cascade River.  The escapement goal  has been met and the state kept the fishery open through the end of December.  There are still a few huge chums in the river as well.  Up at Rockport the stench of rotting fish is pretty strong as all the spawned out Coho and Chum carcasses are everywhere.  The lower Skagit is one of the most polluted rivers in PS with all the bovine farm runoff, pesticide and herbicide runoff from other farms, not to mention a very large built up urban area from Sedro-Wooley to the mouth.  The Coho runs are way down from decades past... but they are doing pretty good considering their odds coming and going to that river system.

Meh, nothing will be done. As for the science, we've known since the mid '70s that Nylon, when swept through a river system, has a greater than 90% mortality for all salmonids, and yet it continues. Me believes it's just pointing fingers towards the money and not the obvious.

I have witnessed the define and destruction of the puget sound rivers for nearly the last forty years.   It all started with the Marine Mammal in the 70’s.  The numbers and variety of predators has greatly increased while our fisheries declined ,  plain and simple.  Tire dust is Junk Science to hide the real problem.

So what your saying is we need to whack some sea lions and seals and up hatchery production...hmm. I'm no scientist but you might be on to something.

Tire rubber eh?  Isnt that stuff on our sports fields cause its safe for kids?   Confusing junk science to further their agenda.  Cant even figure what is true these days.  I choose to go with predators and fishing harvest commercial/native or something before I choose tires....  Heck I believe roundup stuff worse then rubber tires!

Did they ever figure out what happened to the cod fishery in the puget sound?  Ive fish the south puget sound since 1980 and seen the decline of salmon and cod first hand.  Wouldn't you think at least in part that whatever the reason for cod decline would be somehow related to the salmon decline.

18% mortality on rod reel caught salmon.  I know it seems like more but they are tougher than you think.

Where did they find that data?  I bet 1/5 get munched by the seals that follow them up to the boat and hang out behind.

I've heard it was related to the bottom dragging.  There used to be some areas that held large amounts of cod because the bottom had a ton of sand lance.

It's a scientific fact that fresh water kills not only adult Coho, but all adult salmoniods.

Does that include kokanee?

Dont know. I drink Rainier. I do know that lite beer is awfully close to water.

Kokanee, (land locked Sockey),  land locked Silver or land locked blackmouth all survive in fresh water.
