NATIVE FISH SOCIETY P.O. Box 19570 Portland, Oregon 97280 (503) 977-0287 Email: bmbakke@teleport.com March 18, 1998 Mr. Lance Kruzic National Marine Fisheries Service 525 NE Oregon Street Portland, OR 97232-2737 RE: Upper Columbia River Steelhead ESU Biological Opinion Dear Mr. Kruzic: Thank you for sending the additional documentation on the use of hatchery steelhead to recover wild, native steelhead in the Upper Columbia ESU. I had not seen the Schiewe memo of Oct. 7, 1997 nor the Biological Opinion before. In reading those documents, however, a few additional concerns developed that I would like to include for the record on Section !0 Application #1118 sent to Mr. Tom Lichatowich on March 6, 1998. These documents would have contributed to my earlier comments if I had them available at the time, so I hope these additional comments are not too late to be considered by NMFS in this application process. Based on my review I believe the Biop is inadequate to recover the species and will increase the risk and cause lower productivity of subbasin wild, native steelhead populations covered in by the Biop. The foundation for this conclusion is provided in the following comments: 1. The historic use of hatchery steelhead in this ESU did not support the conservation of locally adapted populations of native, wild steelhead and the biological diversity they represent in terms of genetic structure (genetic diversity among and within populations) and the fitness of those populations. The historic hatchery program has established a hatchery swarm of a generic, homogenized steelhead population in the upper Columbia River and related subbasins. The goals of this historic hatchery program are very different from the purpose of recovering locally adapted natural populations in the ESU under the federal Endangered Species Act. However, the Biop, even with the changes described, perpetuates hatchery operations that have caused the present problem of a homogenized hatchery production steelhead stock. A similar problem to this was also identified for the Willamette spring chinook where the NMFS assessment stated the transfer of common hatchery stock among hatcheries and subbasins had homogenized the Willamette spring chinook. However, unlike the Willamette spring chinook hatchery program, the steelhead hatchery program in the upper Columbia ESU has also included out-of-ESU hatchery transfers such as the Skamania summer steelhead stock. This makes a bad situation even worse in the upper Columbia ESU. 2. Rather than begin with a Biop that perpetuates historic hatchery practices and recognized problems along with substantial risks identified in the Schiewe memo, the Biop should move immediately to a WxW cross supplementation program for each subbasin if a hatchery supplementation program is needed. I think the Schiewe memo is correct when it questions the need for supplementation. It may be enough to exclude hatchery production from the subbasins altogether and with harvest controls and habitat repair, allow the native wild stock to restore itself. But if the hatchery is to be used it, should be based only on WxW crosses. The existing Wells Hatchery program should continue, as a backup, to maintain that population, providing it does not jeopardize other listed populations and straying is controlled in upper Columbia River subbasins to maintain the locally adapted populations. The Schiewe memo is interesting because it leads the reader to the action I mention above, but it then backs away from it in the final conclusion. 3. The evaluation by NMFS relies upon local WDFW assessment for changing hatchery operations, but it does not incorporate the very relevant research conducted over the last 20 years by WDFW at the Kalama River Research Station. I could find no reference to this research, even though it is uniquely qualified to help answer questions asked in the Schiewe memo. The Kalama Research has evaluated the reproductive success of non-native second generation hatchery fish and their ability to produce adult progeny. Because this research addresses the questions asked in the Schiewe memo, I would recommend NMFS ask the scientists involved in the Kalama research to participate in the development of a recovery plan for the upper Columbia steelhead ESU. At a minimum their review and comments would be most helpful in developing a Biop for this steelhead ESU. Based on the findings of the Kalama Research Station results, continuing the HxW and HxH crosses in the upper Columbia ESU would continue to contribute to the reduction of fitness for natural populations in the subasin and add to their risk exposure . This result is not consistent with the recovery of native, wild steelhead under the ESA. 4. A life history trait of steelhead not recognized in the Schiewe memo or in the Biop is the repeat spawner. This trait has value to natural populations in terms of genetic diversity, fitness and productivity of locally adapted populations. Some research has shown it to be a relatively large component of native steelhead. Mark Chilcote told me that 22% of a Kamchatka steelhead population is composed of repeat spawners. The NMFS should evaluate the ecological and genetic value of repeat spawners in its steelhead plans and incorporate this life history trait into its recovery program. Since listed kelts are not addressed in the Biop, I am making the recommendation that they be included and a conservation plan be developed to protect repeat spawners from steelhead ESUs. Certainly, the lack of consideration for the safe passage of steelhead kelts around dams on tributaries and in the mainstem is an oversight that could and should be corrected. 5. There is some discussion of nutrient enrichment of steelhead streams from steelhead carcasses. While steelhead carcasses should be considered for this purpose, it may be that stream productivity associated with salmonid carcasses is more closely tied to the amount of salmon carcasses than to steelhead. Steelhead, cutthroat and salmon are probably all linked together in a nutrient wed primarily powered by salmon escapement. Consequently, salmon recovery in the upper Columbia ESU is probably an important factor to successful steelhead recovery and delisting. I would refer you to research conducted in Canada on this topic in Fisheries , American Fisheries Society, November 1997, Vol. 22, No. 11, by Gillian A Larkin. Nutrient enrichment from salmonid carcasses is an important issue and specific standards should be set in a recovery plan for steelhead. 6. Given the uncertainties and risks identified in the Schiewe memo, it seems prudent to call for an independent scientific and public review of the upper Columbia River Steelhead ESU Biop. I am not certain how much external review there is of a Biological Opinion. However, since the Independent Scientific Advisory Committee is presently reviewing hatcheries in the Columbia Basin, it seems that the ISAB should review and comment on the Biop. Also, the Biop should not be approved for a 5-year period because the ISAB hatchery review may identify changes in hatchery operations that could be incorporated in the Upper Columbia River Steelhead Biop. This kind of adaptive management and flexibility is needed considering the risks and uncertainties associated with the upper Columbia River Steelhead ESU. 7. The Biop (p. 12) makes the conclusion: ãBased on available information, the proposed actions are likely to provide a net benefit to Upper Columbia ESU natural steelhead (Schiewe 1997).ä However, the Biop does not complete the thought contained in the Schiewe memo: ãHowever, this conclusion rests on some tenuous assumptions that need to be verified as soon as possible. Most important of these is the degree to which naturally spawning Wells stock hatchery fish contribute to natural production. If these fish perform substantially less well in the wild than do wild fish or fish that resulted from WxW crosses in the hatchery, then the use of Wells Hatchery stock fish in the recovery effort may not provide a net benefit to the listed species. If this is the case, a better strategy may be to supplement only with WxW crosses, or possibly not to supplement at all. Given this critical uncertainty and risk regarding the use of Wells Hatchery stock for supplementing wild steelhead in the subbasins, it would appear the Biop decision is unwarranted and the more conservative approach recommended by the NMFS Science Center should be adopted. In conclusion, the NFS society recommends the Biop address steelhead kelts and provide for the full expression of this life history trait in Upper Columbia River ESU natural steelhead. In addition, we recommend that the Biop be changed to reflect the critical uncertainty and risk identified with using Wells Hatchery steelhead for supplementation of natural steelhead in this ESU. This means using a WxW cross, a captive brood program for wild steelhead, or not supplementing the wild population. Sincerely, Bill M. Bakke, Director cc: Tom Lichatowich Rollie Schmitten Donna Darm
