Malheur Lake, OR, is cri cal habitat for migratory waterfowl in western North America. Historically, the lake and waters adja‐cent to the Malheur Na onal Wildlife Refuge annually produced over 100,000 ducklings, and was used by 35% of the Pacific Fly‐way’s canvasback popula on. In addi on, the lake is also im‐portant habitat for redband trout. The highly invasive common carp were introduced into Malheur Lake in the 1950s, having a devasta ng effect on the lake's habitat and its bird and fish pop‐ula ons. They have destroyed much of the emergent vegeta on and reduced water quality, resul ng in waterfowl produc on declining to 10‐20% of historic levels. The objec ve of our study is to determine if electrofishing is a viable method to significant‐ly reduce recruitment of common carp in Malheur Lake. Fer ‐lized eggs and embryos of common carp will be exposed to a variety of electrical fields that vary in wave form and voltage gradient. Survival to hatching will be compared among treat‐ment and control groups. The small size of common carp eggs required us to build a new device capable of genera ng the strong electrical fields needed to cause high mortality during egg development. Lab tested during a pilot study, we are now conduc ng field trials with common carp at Malheur Lake.

Abernathy Creek Winter Steelhead Spawning
AFTC researchers, in collabora on with Bonneville Power Administra on and the Washington Depart‐ment of Fish and Wildlife, con nue their work on the Natural Reproduc ve Success and Demographic Effects of Hatchery‐Origin Steelhead in Abernathy Creek, WA. The objec ve of this 16+ year study is to iden fy differences between hatchery‐origin (HOR) and natural‐origin (NOR) winter steelhead and pro‐vide informa on to help managers minimize these differences. March and April ac vi es for the project included adult capture, spawning, and release of brood year 2014 smolts. The total adult capture at the end of April was 71 NOR (31 female, 40 males), 158 HOR (66 females, 92 males), and 25 out‐of‐basin HOR strays (5 females, 10 males). From these adults 48 NOR (21 females, 27 males) and 20 HOR (10 fe‐males, 10 males) fish were passed upstream to spawn naturally, with 23 NOR (10 females, 13 males) fish used for hatchery brood stock, represen ng 25% of all parents used to produce 2015 juveniles. Richard Glenn con nued collec on of blood, ovarian fluid, and eggs during spawning in addi on to track‐ing growth and development of offspring from this year’s broodstock. In addi on, Richard, Ben Kenne‐dy, and Kyle Hanson collected gill biopsies to deter‐mine seawater preparedness of HOR smolts. The first release of 4600 brood year 2014 steelhead smolts occurred on April 14th, with the second re‐lease on April 28th (4900 smolts). The final 4900 smolts will be released on May 12th.

Physiology and Nutri on In March and April, 13 feeds were re‐
ceived from the Na onal Fish Hatcheries
for fish feed quality control. As part of
the rou ne analyses, all feeds were also
checked for rancidity. Ann Gannam wrote
the feed memos and contacted the feed
mills when necessary. A possible feed
size issue with starter feeds used at three
NFHs is being inves gated.
Final sampling for the lamprey ammo‐
coete ra on level/water quality study
was completed on March 9th. Ron Twi‐
bell and James Barron collected final wa‐
ter samples and captured all fish for
measurement. Data on lamprey growth
rates and changes in water quality in rela‐
onship to ra on are currently being ana‐
lyzed.
Ann Gannam, Ron Twibell, and Jeff Poole
formulated and made feeds for Dr. Jona‐
than Eya at West Virginia State Universi‐
ty. The four diets will be used in feeding
trials looking at alterna ve ingredients
and gene expression in rainbow trout.
Final sampling for the coho recircula ng
aquaculture system (RAS) study occurred
April 28th. Ron Twibell, James Barron,
Ann Gannam and Kyle Hanson collected
blood and gill samples for further analy‐
sis. Lengths, weights, and fin length
were measured on a subsample of the
popula on in each tank. Ron con nues
to collect and analyze data for a similar
steelhead RAS study that was complet‐
ed at the Hagerman NFH. Ron analyzed
lipid, moisture, and ash content of the
steelhead that were raised in the RAS
circular tanks and in the raceways at
Hagerman NFH.

Kurt Steinke and Ben Kennedy replaced
the destroyed antennas under the Aber‐
nathy Creek bridge with a new system.
Instead of six rigid antennas housed in
PVC, there are two flexible antennas that
each span the en re stream and use Bi‐
omark’s new IS1001 transceiver unit.
Will Simpson, Kurt Steinke, and Doug Pe‐
terson concluded a series of pilot studies
to determine which electrical waveform
causes the greatest mortality in fer lized
eggs and newly emerged fry obtained
from stray hatchery steelhead.
As part of AFTC’s steelhead reproduc ve
success study, two hatchery releases of
steelhead smolts were conducted in
April. A total of 1,000 of these fish had
been implanted with PIT tags, so that
their migra on out of Abernathy Creek
could be monitoring using sta onary PIT
interroga on sta ons.
Will Simpson and Kurt Steinke traveled to
Hermiston, OR, to turn on PIT tag interro‐
ga on systems on irriga on diversions
and bypass channels on the Uma lla Riv‐
er system.
