[env-trinity] More on Klamath Water/Hatchery Issue

Hi Again Tom,

In addition to the disease reference in the flow and hatchery related 
article you sent out, there is also a troubling request to not only hold 
more Iron Gate Hatchery chinook to yearling size but "letting loose the 
ones that are released farther down in the river." Out-planting, as they 
call it in the hatchery business, can increase returns by diminishing 
competition and increasing survival by shortening the length of the river 
journey. It also has the potential to cause a ton of straying, which will 
have the effect of homogenizing stocks on Klamath River tributaries, 
including the Scott and the Shasta. The last stock transfer at Iron Gate 
was 1985-1988 with coho in planted in Middle Klamath tribs. A experiment to 
increase returns of Trinity River Hatchery steelhead by out-planting in the 
1980's lead to massive straying.

This policy is against what is recommended in the Klamath Long Range Plan 
and was disapproved by a committee of agencies and Tribes when 
Klamath-Trinity Hatchery policy was last reviewed in the early 1990's. The 
review was in response to a stock collapse, which may have been related to 
over-production of juvenile chinook in high return years in the mid- to 
late 1980's. I sat on a PFMC sub-committee that delved into reasons for low 
returns ("below the 35,000 wild fish floor") from 1990-1992, and hatchery 
operation was one of the few factors that appeared to stand out as a 
potential causal mechanism. Hatcheries, if operated inappropriately, can 
have a confounding effect on recovery of wild stocks.

Any one wishing more information on the problems related to stock transfer 
can skim Chapter 5 (starts on p. 215) of the the Long Range Plan for 
restoring the Klamath 
(http://www.krisweb.com/biblio/gen_usfws_kierassoc_1991_lrp.pdf) or the SF 
Trinity Action Plan (Chapter 8), both of which I co-authored. Chapter 8 in 
the latter is specifically on the potential side effects of large scale 
hatchery operation: 
http://www.krisweb.com/biblio/sft_usbor_pwa_1994_sftplan/pwa27.htm#PotentialImpacts.

The Humboldt Chapter of the American Fisheries Society passed a resolution 
in 1988 to try to curb California stock transfers of anadromous fish, which 
I could provide for anyone with a burning interest in the topic.

Cheers,

Pat Higgins
