1. RESEARCH USES DNA TO IDENTIFY OCEAN SALMON'S <st1:place w:st="on"><st1:PlaceType
w:st="on">HOME</st1:PlaceType> <st1:PlaceType w:st="on">RIVER</st1:PlaceType></st1:place><br>
<br>
<st1:PlaceName w:st="on">Oregon</st1:PlaceName> <st1:PlaceType w:st="on">State</st1:PlaceType>
<st1:PlaceType w:st="on">University</st1:PlaceType> scientists are teaming with
commercial fishermen on <br>
a new research effort to rapidly identify the home <st1:PlaceType w:st="on">river
basin</st1:PlaceType> of <st1:PlaceName w:st="on">chinook <br>
salmon</st1:PlaceName> found in the <st1:place w:st="on">Pacific Ocean</st1:place>
using genetic testing.<br>
<br>
Their goal is to learn more about offshore schooling behavior and stock <br>
composition of salmon and ultimately to prevent coast-wide fishing <br>
closures. The closures aim to protect weak stocks like those of the <st1:place
w:st="on"><st1:PlaceName w:st="on">Klamath</st1:PlaceName> <br>
<st1:PlaceType w:st="on">River basin</st1:PlaceType></st1:place> that may
constrain an otherwise healthy fishery.<br>
<br>
Funded by the Oregon Watershed Enhancement Board, and managed by the Oregon <br>
Salmon Commission, the pilot project is called the Cooperative Research for <br>
<st1:State w:st="on"><st1:place w:st="on">Oregon</st1:place></st1:State>'s
Ocean Salmon, or CROOS.<br>
<br>
The program is already seeing results.<br>
<br>
During the June 4 salmon fishing opener, fishermen caught chinook salmon <br>
off the <st1:State w:st="on">Oregon</st1:State> coast between <st1:City w:st="on">Newport</st1:City>
and <st1:City w:st="on">Florence</st1:City> and OSU scientists were <br>
able to positively match the DNA from the fins of 71 of the fish to <br>
establish their origin from river systems in <st1:State w:st="on">California</st1:State>,
<st1:State w:st="on">Oregon</st1:State>, <st1:State w:st="on">British <br>
Columbia</st1:State> and <st1:State w:st="on"><st1:place w:st="on">Alaska</st1:place></st1:State>.<br>
<br>
An ongoing project coordinated and funded by the National Oceanic and <br>
Atmospheric Administration involving 10 labs from <st1:State w:st="on">California</st1:State>
to <st1:State w:st="on">Alaska</st1:State> -- <br>
including OSU's <st1:PlaceName w:st="on">Hatfield</st1:PlaceName> <st1:PlaceName
w:st="on">Marine</st1:PlaceName> <st1:PlaceName w:st="on">Science</st1:PlaceName>
<st1:PlaceType w:st="on">Center</st1:PlaceType> in <st1:City w:st="on"><st1:place
w:st="on">Newport</st1:place></st1:City> -- has identified <br>
unique genetic profiles for 110 different salmon populations based on their <br>
home river basin.<br>
<br>
Scientists and resource managers previously were unable to identify stock <br>
composition of both wild and hatchery fish originating from the Pacific <br>
Northwest, <st1:country-region w:st="on">Canada</st1:country-region> and <st1:State
w:st="on"><st1:place w:st="on">Alaska</st1:place></st1:State>.<br>
<br>
Project leaders say that this new technology allows scientists to assess <br>
the origin of an individual fish with remarkable accuracy.<br>
<br>
"This was the key for us to utilize the technology," said Michael
Banks, an <br>
OSU geneticist and director of the Cooperative Institute for Marine <br>
Resources Studies, a joint Oregon State-NOAA research collaborative. <br>
"Having a bank of DNA profiles allows us to approach 'real-time' <br>
identification of fish. What used to take months, or even years, we've been <br>
able to pare down to about 48 hours."<br>
<br>
During the June field testing, participating fishermen caught chinook <br>
salmon off the <st1:State w:st="on">Oregon</st1:State> coast between <st1:City
w:st="on">Newport</st1:City> and <st1:City w:st="on"><st1:place w:st="on">Florence</st1:place></st1:City>
and collected a <br>
fin-clip from each fish for DNA analysis. OSU scientists were able to match <br>
genetic profiles of fish from river systems as far south as <st1:City w:st="on">Battle
Creek</st1:City> in <br>
<st1:State w:st="on">California</st1:State>, and from as far north as the <st1:PlaceName
w:st="on">Babine</st1:PlaceName> <st1:PlaceType w:st="on">River</st1:PlaceType>
in <st1:State w:st="on"><st1:place w:st="on">Alaska</st1:place></st1:State>.<br>
<br>
Traditional efforts to identify the origin of ocean-caught salmon came from <br>
coded wire tags inserted into the snouts of a small percentage of hatchery <br>
fish. Those tags were useful for determining broad-scale distributions of <br>
stocks caught in fisheries, but revealed only the origin of select tagged <br>
fish. The time and location of these tagged fish also have been too general <br>
reported by week and catch area.<br>
<br>
The coded wire tag data weren't usually available until several months <br>
after the season ends.<br>
<br>
Using DNA testing, however, will allow the scientists to rapidly assess the <br>
origin of any chinook salmon caught off the West Coast -- not just coded <br>
wire-tagged hatchery fish -- and identify with about 95 percent accuracy <br>
its home river system.<br>
<br>
In theory, researchers say, they could test several salmon in schools from <br>
different locations to see what percentage of them originate from a weak run.<br>
<br>
"This could lead to the introduction of some degree of in-season harvest <br>
management," said Gil Sylvia, an OSU economist and superintendent of the <br>
Coastal Oregon Marine Experiment Station. "Having accurate information <br>
could lead to reducing access to some stocks in certain areas at certain <br>
times. But it is just as likely that it could result in decisions to open <br>
areas of the coast where higher concentrations of harvestable fish <br>
populations are."<br>
<br>
The researchers will compare their genetic assessment with coded <br>
wire-tagged fish to test the efficacy of the project.<br>
<br>
Many of <st1:State w:st="on"><st1:place w:st="on">Oregon</st1:place></st1:State>'s
commercial fishermen, who have been shut down from <br>
pursuing their livelihood this summer, say they are excited by the research.<br>
<br>
"I started fishing in 1970 and this is the most optimistic I've been about
<br>
any kind of research relating to salmon," said Paul Merz, who fishes out
of <br>
<st1:City w:st="on"><st1:place w:st="on">Charleston</st1:place></st1:City>.
"I'm still a cynic when it comes to management decisions. But <br>
this is the science that has been missing in all of the policy arguments -- <br>
and it's something where you can see the immediate results."<br>
<br>
Jeff Feldner, a fisherman from <st1:place w:st="on"><st1:City w:st="on">Logsden</st1:City>,
<st1:State w:st="on">Ore.</st1:State></st1:place>, said that seasons are <br>
designed to minimize the impact on the weakest runs.<br>
<br>
"The problem," he pointed out, "is that we haven't known enough
about the <br>
fish that are out there. Using information gathered over the summer to help <br>
predict where the fish will be next year doesn't help the fishermen. We <br>
haven't had a way of knowing in 'real time' where the fish are and where <br>
they've come from. Now we do."<br>
<br>
The Oregon Watershed Enhancement Board has funded this pilot study for one <br>
year with a $586,391 grant, which will allow 50 <st1:State w:st="on"><st1:place
w:st="on">Oregon</st1:place></st1:State> commercial vessels <br>
to make a total of 200 fishing trips, and allow the scientists to run 2,000 <br>
DNA samples. As many as 90 vessel owners have expressed an interest in <br>
participating.<br>
<br>
"We need additional funding to continue the research," said Nancy <br>
Fitzpatrick, lead administrator of Project CROOS and an employee of the <br>
Oregon Salmon Commission. "One year just begins to give you information, <br>
but it isn't enough to determine all you need to know about salmon. Fish <br>
have fins, as they say, and they tend to move from one location to another.<br>
<br>
"Where you find them one year isn't necessarily where you'll find them the
<br>
next."<br>
<br>
Fitzpatrick says any changes in how the oceans are managed for salmon would <br>
come from the Pacific Fishery Management Council, a regional council with <br>
members from <st1:State w:st="on">Oregon</st1:State>, <st1:City w:st="on">Washington</st1:City>,
<st1:State w:st="on">Idaho</st1:State> and <st1:State w:st="on"><st1:place
w:st="on">California</st1:place></st1:State>, that recommends <br>
fishery management measures to the National Marine Fisheries Service.<br>
<br>
The OSU researchers are keeping track of the salmon through an onboard <br>
electronic traceability system developed by the university over the past <br>
several years. This innovative barcode system allows commercial fishermen <br>
to log the location, date and time of the capture, as well as onboard <br>
handling techniques, for every fish captured.<br>
<br>
Each fish harvested by a participant receives a metal tag with a unique <br>
number and bar-code. A website under construction will eventually allow a <br>
consumer to access basic information about the salmon: where and when it <br>
was harvested, by whom, and from which river it originated.<br>
<br>
Eventually, such a tool may play a major role in marketing, according to <br>
Michael Morrissey, director of the OSU Seafood Laboratory in <st1:City w:st="on"><st1:place
w:st="on">Astoria</st1:place></st1:City>, and a <br>
principal investigator in the CROOS project.<br>
<br>
"By identifying the river system through genetics, and being able to <br>
accurately label a fish as 'wild,' the potential exists for fishermen to <br>
brand their product and increase the value to consumers," Morrissey said. <br>
"One such example is <st1:place w:st="on">Copper River</st1:place> salmon,
which often command twice the <br>
market price of similar fish, because of the attributes attached to it."<br>
<br>
As part of the study, local salmon processors and buyers are returning some <br>
of the heads from the specially marked fish to the <st1:place w:st="on"><st1:PlaceName
w:st="on">OSU</st1:PlaceName> <st1:PlaceName w:st="on">Hatfield</st1:PlaceName>
<st1:PlaceName w:st="on">Marine</st1:PlaceName> <br>
<st1:PlaceName w:st="on">Science</st1:PlaceName> <st1:PlaceType w:st="on">Center</st1:PlaceType></st1:place>,
where scientists will conduct tests on their otoliths. <br>
Otoliths are crystalline structures located in the inner ear and act like <br>
growth rings in trees, recording not only age, but chemical elements that <br>
provide clues to the environment in which the fish lived.<br>
<br>
Some of the fish stomachs will be retained by participating fishermen and <br>
given to scientists to reveal clues about the salmon's diet, including how <br>
the proportion of baitfish consumed might vary by season and between areas. <br>
The fishermen involved in the project will contribute data on oceanographic <br>
conditions where the fish were caught, including depth and temperature. <br>
Some of the fishermen participating in the project say they are fascinated <br>
by the science and hope it will help them locate fish more effectively, as <br>
well as keep the season opened.<br>
<br>
"Every year, it seems like the challenges for commercial fishermen keep <br>
getting worse with restricted limits followed by complete closures," Merz <br>
said. "A lot of fishermen have packed it in. But this project gives me
some <br>
hope. If it works the way it seems like it can, and if management is <br>
adjusted accordingly -- and that's a big if -- then it might be enough to <br>
keep me going. If not, I'll be looking for a new line of work and get on <br>
with my life."<br>
