THE NATIONAL ACADEMIES

Advisers to the Nation on Science, Engineering and Medicine

The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences.

The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering.

The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.

The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chair and vice chair, respectively, of the National Research Council

Preface

Atlantic salmon are symbolic of a time when the biological endowment of the eastern United States was richer and more diverse than today. These impressive fish were once abundant in the rivers of Maine, and their range extended south and west as far as the Connecticut River and perhaps even to the Hudson River. Today the distribution of wild Atlantic salmon in the eastern United States is restricted to a few rivers of Maine where total annual runs are numbered in hundreds of fish rather than the tens or perhaps hundreds of thousands of the past.

In the year 2000, the U.S. Fish and Wildlife Service and the National Marine Fisheries Service listed Maine Atlantic salmon as an endangered species under the distinct population segment language of the Endangered Species Act (ESA). This decision has the potential to trigger regulatory actions that might have economic impacts on agriculture, aquaculture, forestry, and other activities in Maine.

This National Research Council committee was asked to describe what is known about the genetic makeup of Atlantic salmon in Maine, and we did so in a report issued in January 2002. We were also asked to assess the causes of decline and to suggest strategies for the rehabilitation of Atlantic salmon in Maine. This document responds to that latter charge.

To set the stage, we must consider the remarkably complex life cycle of Atlantic salmon. This is a species that is exquisitely adapted to two very different environments. Adult fish mature in an ocean environment and then return to their natal freshwater streams to breed. The newly emerged fry develop, and after a period in their natal streams, the fish go

down river to the ocean where they must transition to a very different physiological state as they enter the ocean environment. The fish migrate as far as the western coast of Greenland, and after approximately 2 years the surviving adult fish return to their natal streams to breed, thus completing the cycle. Unlike their Pacific relatives, a small number of Atlantic salmon may once again return to the ocean to repeat the cycle. The basic problem is that too few adult fish now return to maintain a stable population, and the present demographic trajectory appears to predict extinction of Atlantic salmon in Maine.

Obviously, the current plight of Atlantic salmon in Maine cannot be discussed in isolation. They are embedded in a larger biological and physical system that is highly dynamic and is in part responding to imperfectly understood global processes of change. Global climate systems have fluctuated over the past 100,000 years, and the range of Atlantic salmon must have expanded and contracted repeatedly in response to those larger forces. The history of European colonization of North America coincides first with a cooling of climate associated with the little ice age and then with a subsequent warming period that is still in progress. These global factors are superposed on many regional and local influences. For example, most Maine rivers are dammed, often multiple times, denying suitable spawning habitat. Industrial logging and agricultural activities have influenced local watersheds, stream quality, and stream flow regimes. Acid rain from regional industrial activity has also affected stream quality. Yet many of these factors have improved over the past quarter century in response to environmental legislation and to changing industrial and land-use patterns. The biological community has also changed, owing to introductions of nonnative species and concomitant ecological shifts driven by the changing physical setting. Fishing was once a serious cause of mortality, but that is now much reduced by prohibitions on fishing, both in Maine’s rivers and in the ocean, although some mortality might still occur as the result of bycatch with other fishing activities. Thus, the picture appears to be one of gradual environmental improvement. Despite that, populations of Atlantic salmon in Maine are still declining.

Clearly, a large number of potentially interacting factors impinge on the fate of Maine Atlantic salmon. There are very few quantitative data on the impacts of most of these factors on salmon reproduction and survival. Our committee has worked diligently to assess the threats to salmon in Maine and to make reasonable inferences about how these might be mitigated in the face of limited information. We are faced with a problem of ecosystem management where management choices are shrouded in uncertainty. Many variables affect the system, some yet to be identified, but only a small subset of these variables is subject to manipulation. In short, the challenge faced by our committee was to address a real-world prob-

lem in applied biology. This challenge has humbled us. It presented us with a case study in the manifold complexities of biological and human systems, and it taught us that there are few strong levers available to the real-world system manager.

The practical question of what is happening to the fish and to the ecosystems in which they are embedded remains. What factors are responsible for the observed decline and what levers are available to the manager to move the system toward a more sustainable end point? Our committee has debated this central question at length. From the management perspective, we review the governance system and consider the success or lack thereof of hatchery supplementation. We also consider the likely effects of dam removal as options worthy of special attention. We do not claim to have a magic solution to the long-standing problem facing Atlantic salmon in Maine. What we offer instead is an analytical framework for evaluating management options and for establishing priorities. This framework is drawn from risk and decision analyses; at its best, those techniques can assist in setting priorities and in identifying those actions most likely to be effective. Like any algorithm, risk and decision analyses are no better than the quality of the available data, but the application of the framework does assist in identifying crucial missing information, and it can reveal those factors of minimal importance, because the larger system is insensitive to their manipulation. We appreciate the difficult and challenging tasks faced by those charged with the implementation of a recovery plan for salmon, and we hope that the analytical framework described in this report will serve to assist both managers and recovery planners.

The task of our committee was made much easier by the many individuals who testified before us during the course of our open meetings in the State of Maine. We are grateful for their willingness to share their collective wisdom. Space does not permit the individual acknowledgment here of everyone who helped the committee through testimony, advice, and sharing of written information, although we are extremely grateful to all of them, and the wiser for their efforts. They and others who helped the committee in various ways range from elected officials to volunteers and from government biologists to members of private organizations. They and the experts who reviewed this report, to whom we also are extremely grateful, are listed in the Acknowledgments. However, Ed Baum deserves special mention here for his long service in generating knowledge of Atlantic salmon in Maine and for the wealth of information that he shared with this committee through his book and presentations to us.

Chairing a committee faced with a difficult and controversial charge can be very hard work. In this case the burden was made light by an

exceptionally knowledgeable and cooperative committee. I learned a great deal from my colleagues, and I approach the end of this report with a sense of regret that the fellowship associated with our work has reached an end. The superb staff of the National Research Council also eased our task. Our study director, Dr. David Policansky, is himself an expert in fish biology, genetics, and conservation policy. Dr. Policansky contributed to the final report in numerous ways, and the report is much better because of his professional touch. Dr. Susan Roberts and Leah Probst contributed their expertise and skill to the report’s quality as well, and we are grateful to Jennifer Saunders, Bryan Shipley, Dominic Brose, and John Brown for their attention to the needs of the committee throughout its meetings and for their attention to detail in production of the report. We also thank Ruth Crossgrove and Mirsada Karalic-Loncarevic for their editorial and research efforts.

Because of the pervasive and substantial decline of Atlantic salmon populations in Maine over the past 150 years, and because they are close to extinction, a comprehensive statewide action should be taken now to ensure their survival. The populations of Atlantic salmon have declined drastically, from an estimated half million adult salmon returning to U.S. rivers each year in the early 1800s to perhaps as few as 1,000 in 2001. The report recommends implementing a formalized decision-making approach to establish priorities, evaluate options and coordinate plans for conserving and restoring the salmon.
