Integrating Science and Policy: Enhancing Decision-Making in Fisheries Management

This paper examines the interplay between science and policy in decision-making processes, particularly in fisheries management. It addresses the characteristic challenges of management questions, the impact of scientific uncertainty, and the need for interdisciplinary approaches. By discussing the influences of demographics, risks, and various scientific disciplines—such as population dynamics and ecology—this work emphasizes the importance of evidence-informed policy. With insights from the Yakama Nation Fisheries, it advocates for effective integration of scientific knowledge into sound management practices.

  1. Integrating Science and Policy: The role of science in decision-making

  2. Science vs Management Science involves: Management involves: • Very narrow questions • Few variables • Controlled experimental conditions • None of these 2

  3. Management and science Management Decisions 3

  4. The management “niche” An n-dimensional hypervolumebounded by the limits of tolerance to science, law, and policy considerations (with apologies to G. Evelyn Hutchinson) 4

  5. Influencing policy • We can be wrong: Interesting to scientists, death to policy making • We disagree: Challenge and debate are essential to good science; lack of consensus confuses policy making • We are uncertain: Nature of the beast, but difficult to accommodate in policymaking 5

  6. Different technical disciplines – “If your only tool is a hammer, every problem looks like a nail” • Population dynamics • Ecology • Hydrology • Genetics • Nutrition/fish health • Traditional ecological knowledge – tribal cultural perspectives • Which is “best available”? Which, what, whose science? 6

  7. Demographics“Density effects” Crowding + Competition + Predation = lower survival OR Genetics? “Hatchery effects” Genetic selection - Altered behavior - Fitness loss = lower survival

  8. 8

  9. Policy considerations: • Correct diagnosis of the problem? • What level of confidence? • Appropriate remedies • Risk structure: How are the risks and benefits distributed? • Does the evidence indicate that a change in policy is warranted or prudent? Review Framework 9
