Simulating a natural envi ronment The hatchery simulates the salmon's natural growing envi ronment by providing clean, cold water. Fresh river water enters the hatchery and is filtered before being pumped to the various tanks and ponds. Large debris, such as leaves and twigs, is re moved as water passes through screen filters. Smaller debris is removed at sand filters, and harmful bacteria are removed as the water passes through ul traviolet lights. Salmon return Salmon rearing begins with adult spring chinook returning upstream from April through dent The dinner served as an op portunity for Warm Springs to discuss local efforts to enhance Indian education in relation to the national efforts of the N1EA.

The hatchery barrier dam requires all fish to climb the fish ladders into the hatch ery, where wild and hatchery fish are separated. Wild fish are released above the hatchery barrier, while hatchery fish, identified by tags, remain in holding ponds until they are ready to spawn. Hold ing ponds are kept at 50 degrees Fahrenheit because warmer wa ter causes the fish to spawn too soon. As river temperatures rise above 60 degrees in the sum mer, chillers cool the water be fore it is pumped into the hold ing ponds. Spawning Spawning begins in August and continues through Septem ber. The brood stock, or adult fish used for spawning, in the holding ponds are moved to the vention in North Carolina. Issues surrounding continued national legislative activities, ad vocacy in Washington D.C., and website development were also discussed. The NIEA is planning a youth leadership development conference in Spokane, Aug 18 20. The organization has played By Shannon Keaveoy Spilyay Tymoo It wasn't always easy but af ter 25 years of efforts, nearly 5,000 more chinook salmon struggle their way back upstream to the Warm Springs National Fish Hatchery each year. "Our job is to raise fish. We know we've been successful because we're getting more fish back every year and they are healthier," said Mavis Shaw, fish biologist and assistant man ager at the hatchery. But several near catastro phes could have ruined it all. In 1999 a large gas spill on Beaver Butte Creek forced the hatchery to pack up all the small fry and move them in a truck to the Round Butte state hatchery. The smolts were quickly released in the river in hopes they would be far enough downstream before the gas reached the hatchery. All the animals living on the river near the hatchery left on their own accord. Bugs were the main casualties at the hatchery. "We'll never know what would have happened to our fish, if we hadn't taken the ac tions we did. But we do know that lots of fish died directly where the spill happened," said Shaw. During the 1996 flood, dedicated staff worked around the clock shoveling mud away from the machinery to keep the hatchery running and to keep the fish alive. r Sandbags were stacked against the back door to pre vent rapidly rising river water from flooding the hatchery. Again, due to staff efforts, not a single fish was lost. Another year, a wild fire surrounded the hatchery on all sides. Now, as the hatchery nears its 25,h anniversary celebration, the facility releases nearly 450,000 juvenile salmon into the river each year. spawning area where hatchery employees remove eggs from the females and fertilize them with milt from the males. To gather enough eggs to re stock the river at optimum level, up to 700 adult fish are needed for spawning When available, 1 percent of the wild salmon com ing through the facility are added to the hatchery brood stock to retain genetic traits. Incubation The fertilized eggs are poured into incubation trays. Clean, cold, oxygen-rich water is pumped through the tray suck, which holds 6,250 eggs per tray. Optimum water temperature for proper growth at this stage is 50 degrees. Winter river temperatures drop to freezing, so boilers heat the water before being pumped a prominent role in getting im portant legislative bills passed for Native Americans. A recent success of the or ganization is the Civics Educa tion Bill, an effort to help pro mote improvements in how teachers convey American his tory in the classroom. Also, a native language rcvi talization bill recently passed. The Warm Springs National Fish Hatchery opened its doors Aug. 26, 1978, and began to stock reservation waters with salmon and trout. It is located on the Warm Springs River, a tributary of the Deschutes River, which flows into the Columbia. The Warm Springs River system boasts the only healthy wild salmon run on the reser vation. Some 1,200 wild salmon pass through the hatchery each year. The wild salmon are sepa rated from the hatchery fish and allowed to pass upstream. A small percentage is kept for genetic stock at the hatch ery. The U.S. Fish and Wildlife Service operates the hatchery, but the tribes have sole man agement responsibility for fishery resources on the res ervation. Shaw says ocean conditions have been ideal the last five years, assisting in the high rates of salmon return. Also, she believes, overall water quality of the rivers has improved. The general population has become more aware of major river polluters, like agricultural pesticides, and large spills are less likely. "Fish are a major indicator of your water supply," she says. Commercial fishing regula tions banning large mesh nets in favor of tangle nets, mini mizing damage to the fish, have aided, salmon in their jeurnejt tome- J.U But close observation of whar the salmon respond to in the hatchery is equally respon sible for rising numbers of salmon in the rivers. Fish are inoculated two times each summer to prevent spread of disease. Shade covers were erected over spawning pools, after staff observed the hot sun was burning the backs of fish.

Nursery tanks In December and January fry are transferred to nursery tanks and fed frozen fish protein. The hatchery water is warmed to increase feeding activity and speed up the growth process. Outdoor runways By March, fry develop into fingerlings and are put into the outdoor raceways after being acclimated to cooler outside tem peratures. In April and May, hatchery fingerlings are tagged with a coded wire tag in the snout and an adipose fin clip to distinguish Kah - Nee The Organization is in the The organization is in the process of revising President Bush's executive order on In dian education. NIEA is working on the re authorization of national 1 Icadstart, higher education, and special education programs for Native Americans. The NIEA was founded in 1969 to give American Indians painted cement pools will eventually be painted camou flage to match the color of river stones, helping create an environment similar to the river. Staff believes this will cre ate an environment more con ducive to spawning. Populations in the 30 spawning pools have been low ered to 25,000 juveniles per pool, down from 60,000 juve niles that was once common. Lower density populations have resulted in better salmon return rates. An experiment with three pools will help the hatchery find the ideal population den sity for each pool. Over time, the hatchery will record the rate of return for each pool in hopes of discov ering the ideal density. After trial and error, the hatchery has found that moist fish food, primarily consisting of herring, keeps the fish healthier. Staff, though, is careful to not overfeed the fish. They use measurements and weights from wild fish to gauge the ideal size for hatchery fish. "There was a time early on when we were raising hogs. But we realized big fish were not necessarily ideal," said Shaw. "We're just always keeping our eyes open to see how we can make improvements," ex plained Shaw. Hatchery visitor hours are daily from 9 a.m. to 4 p.m. Full-size salmon models and exhibits are displayed in the visitor center, and a self guided walking tour provides a view of the hatchery and its operations. Guided tours are available upon request, Throughout the year, visi tors can observe different stages of salmon rearing. The 25,h anniversary cel ebration of the hatchery is scheduled for Aug. 26 at the hatchery grounds. For more information call (541) 553-1692. them from wild fish. Most young salmon stay in die raceways to develop until the following spring, although some early devel opers are ready to migrate in the fall. Smolt release At about 16 months, the fingerlings have developed into smolts and are ready for migration. Each year approxi mately 750,00 smolts are released into the Warm Springs River and join wild smolts on their journey to the Pacific Ocean, where they will feed and grow for one to four years before making their return to the Warm Springs River to spawn, continuing the salmon's life cycle. - Ta anil Alnsll and Alaskan Natives a national voice in their struggle to im prove access to educational op portunities.
