Results from competition experiments performed in small screened
enclosures within the North and Middle forks of the Teanaway River
suggested that: 1) the presence of hatchery-reared steelhead negatively
impacted growth of naturally-produced rainbow trout, but did not impact
the growth of spring chinook salmon; 2) the presence of hatchery-reared
spring chinook salmon negatively impacted the growth of wild spring
chinook salmon; and3) the presence of wild spring chinook salmon did not impact the growth of wild rainbow trout. The
potential impact of hatchery spring chinook salmon on wild rainbow trout
was not examined.
5465 total which 104 were lost hatchery steelhead over Prosser Dam as of Jan. 28th is not bad compared to the recent counts, and lots more still to come-as this count does not end until 6/30/2010.
The Yakama Nation will continue to push for Hatchery and Wild Salmon for their interests whether cerimonial or to sell and BPA will continue to finance it, this is not going to change. They could care less about Steelhead except for sale purposes.
