Thought I would post up this e mail thread obtained in a Public Document Request (PDR) as it offers a glimpse at two things. First up the relationship between the QIN & WDF&W staff. Amazingly enough documents obtained in the PDR's show at the technical level it is professional other than every now and then it gets a little off track as in one document obtained where a QIN staffer called a WDFW Bio a SWAG Bio. Swag is "Scientific Wild Ass Guess"

This particular e mail concerns the release mortality for commercial nets and Coho. It is my understanding that Fish Program intentionally left out Coho in the ISP panel mandated by the court settlement in Willapa. The importance? Well the agency continues to try and work around the Humptulips Coho situation with the failure to make natural spawner escapement and the Willapa Chinook. It is a issue in the sense that if WDF&W attempts circumvent HSRG or a management plan on one thing one can rather safely assume they will do it in another.

I highlighted the portion on release mortality below and the QIN's Mr. Jacobson's thoughts are pretty much on the mark from what I have learned broodstocking over the years.

Jim,

Your email below has been forwarded to the IFSP.

Thanks for the assist.

Cheers

Good afternoon Jim,

Attached is the most up to date version of the Grays Harbor Planning Model.
We haven't discussed schedules at this time. We've been worked for find and
correct computation and cell reference error. We appreciate any input you
provide.

I will make sure that your comments of the net release mortality issues are
sent forward.

Mike

Mike--

Is there a planning model for GH that you could provide me to review and
offer QIN proposed changes.

Also on the commercial net release mortality that the Mobrand group is
working, Steve suggested I should relay our technical information or issues
through you.

I wouuld propose that the wild coho brood stocking information from 1986 on
for the Hoh River is probably available through Roger Mosely.

The main point of this was that Roger and we found out that female coho
taken from the lower Hoh and earlier in the season did not survive well at
all.

I think the lower and earlier ones all died, even though a good number
looked alive and well right up to before their eggs were to mature.

When checking them up to that time at a certain point we would find them
dead and their eggs having not separate from the skeins. Males seemed to do
fine.

Therefore I would recommend that any release mortality be assessed from the
female survival perspective. Coastal wild escapement estimates are based on
the number of reeds dug by females.

Any time/area situation in the lower freshwater area that had a similar
impact on female salmon, may render an overall survival rate of 50%, which
would be meaningless as far as achieving

escapement objectives. One of the presenters in Olympia before the Mobrand
group also cited their similar experiences brood stocking for what I believe
was the Wishkah group.

Good question Jim,

I'll leave that up to Kirt or Steve to answer.

Mike-

Regarding the forum yesterday and the charge to Lars Mobrand and the other
panel members, are there avenues where QIN would be able to provide
technical information or recommendations to the panel?

Hi guys,

Below is the web link to all of the materials that have been presented to
the scientific panel that is evaluated the net release mortality rate.
Please enjoy.

Jim,

I have a question. Do you know the origin of the estimated Humptulips
hatchery stray estimate? In the GH coho forecast model in the run
reconstruction tab within the column labelled "Humptulips Hatchery Strays"
(column AQ) there is a comment that says "0.8 is applied to total escapement
est. for Humptulips, this calculation assumes that 20% of fish on spawning
grounds are of hatchery origin. Cannot calculate w/o spawner surv. Data" .
First, this column multiplies the Humptulips escapement estimate by 0.8.
This produce is then used in the total HATCHERY escapement. Seems that
multiplying by 0.8 is assuming that 80% of the spawners are hatchery origin.
I recall a discussion with Kirt about some CWT analysis that determined the
stray rate. Do you have any recollection? I'm trying to update all
documentation associated with forecasts.

Thanks for any help you can provide.
