It was my understanding that coho spawned every three years? One year in freshwater and two in the ocean, except for some northern run fish that spend up to three years in the ocean. That would mean that this years coho came from 2005. Jacks spend one year in the freshwater and one year at sea, making them two years old.

"ocean survival"    WHAT A CROCK !!!

I guess those Alaskan fish spend their 2 or 3 years in a different, cooler Pacific Ocean than our fish do.
?

Fish Farm Gauntlet would be more accurate I believe.

In fact they do.  Our "local" salmon spend their ocean cycle outside of west cost VI.  Alaskan runs is up close to Bearing sea, alot cooler.
This ocean warming trend off coast of west VI should not be taken lightly.  fish species usually found south is moving northward and the our salmon's usual diet needs cold water and it's not abundant off VI.

The brood year of the 2008 adult coho stock is 2005.

What's your source BwiBwi?

BC salmon migration


Alaska salmon migration (from U of Alaska)


Oh and with warming trend parasite infections also increase.
One of the most alarming climate-related impacts is a disease caused by the parasite Ichthyophonus hoferi.  Some salmon (this parasite also infects other fish species) upto 1/5 had to be discarded because of this parasite infection.  Fish infected is bad for eating and they also die before reaching spawning ground.

Wow, that is bad news, folks. If this year's coho return from 2005 stock is this bad, wait till next year when the 2006 stock come back (with only 1/2 of 2005 stocking). We aren't seen nothing yet.

[BwiBwi]

Well not necessary next year would be bad.  2004 release at Vedder was lower than 2005 but last years return is alot better than this year.  But then last years fish on the average's smaller than this year.  Who knows may be with less competition those smolt had more food to eat and next years return just might be better.  (okay I'm keeping all fingers and toes crossed)

Thanks for posting that info BwiBwi, very interesting... Where did that chart come from? The migration route on the north side of the island seems to be missing.

It's been common knowledge that the Alaskan Commy fishery hammer our fish when they come looking for land to start their homeward migration... Last year, from what I heard, the coho came to land slightly more south of the typical alaskan fishing grounds, which resulted in poorer coho catches for them, and a banner year for us... This was hearsay though, but from an educated source.

Cheers,
Nicole

Both chart come from university research committees.  Pattern only shows off shore migration as you can see chart starts after salmon leave Juan de Fuca straight and ends after fish comes near shore close to QCI.  This info is to show how Alaskan salmon still does better than ours out in the sea due to a more northernly migration route as Alaskan salmon route travels well into Bering Sea.  Which is cooler and supposingly feed is more abundant.

Our salmon has been caught by Alaskan fisheries (commercial and recreational) in the past and will continue (just like us can't avoid catching WA and OR bound salmon).  Many southern Alaskan rivers in the pan handle area will travel in a similar pattern as our salmon in the last lag of their journey home.  Supposingly the fishing treating signed not long ago between our governments will reduce the catch on our salmon (time will tell).  BUT this is only commercial salmon fishery.  At this time, Alaskan cod fishery is doing more damage to our salmon stock (esp. chinook) due to their fishing method (by net), and this has yet to be addressed.  BC also has commercial cod fishery but their fishing method is only limited to drop traps, hence salmon bycatch is next to zero.

Are you guys aware that " any Alaska state ( 6 mons or more res. ) citizen is entitled to catch in any manner ( snagging, dipnet , etc.) 50 to 100 sockeye or pink salmon for subsistunce use with out a license" Man , women, & children. Sockeye are the prime target. All catches must be " Inriver catches" . The only stipulation is they are caught inriver & during alotted seasons. In Alaska there are NO differences regarding heritige,,,,,IE whtie, native, etc. ALL citizens are Alaskans. Indians compete for the catch on an equal basis. NO reservations, bands, special rights ,,,none.

Smoke that one a while.....................
All came about 30-40 years ago with a treaty buy out from the oil money. Most of the Good tribal assoc.s set up business' and baught cannerys , boats, land  etc. And have become good business people, sending their you people to college...............

 Coho returns to the Vedder have been poor over the last four years. Last year (2007 ) we had a return of 14,000 adult coho and about 500 jacks. This year it looks like we will top out at about
10,000 adults and 1500 jacks. The return of wild fish appears very weak this year compared to last year. All our indicator streams are well below normal levels.

[BwiBwi]

Let's hope with the triple amount of jack returning this year plus improving ocean condition, next year coho return will be better than the past few.

Hey BwiBwi,

Thank for posting the charts.  I believe it's good for readers here to know that there's some data and research behind what some participants post on this site.  It's not all just personal opinion and griping.  I always try to post my sources whenever I can.

Have you got any charts on ocean temperatures?

As you can see in the very last imagery, July 7 2008, effect of La Nina is pretty much gone.  We are now back to neutral state.




The NPGO was identified by Professor Emanuele Di Lorenzo and colleagues using satellite data and is described by a pattern of ocean currents which strengthen and weaken on decadal and multi-decadal timescales.  The fact that changes in the NPGO coincide with changes in the ecosystem are consistent with other studies that show decadal variations in various other regional marine ecosystems.

That's pretty interesting water chemistry data.  Anything on temperatures?
