<br />• Reintroduction in the UCR will be an essential component of plans to recover the <br />razorback sucker. The prospects for successful reintroduction may be enhanced by <br />a local facility that can pay adequate attention to site adaptation. <br />~ • Protocols should be refined for tracking all individuals from any future introductions. <br />• Translocations should be given a higher priority for establishing populations of listed <br />fishes. <br />~ Control of Introduced Fishes: <br />• Nonnative fishes that are abundant in Colorado pikeminnow nursery habitat may be <br />the most significant impediment to increasing recruitment of that species. Effective <br />control measures need to be developed and implemented. <br />~ Research, Monitoring, and Data Management: <br />• The recovery program would benefit from broader review, synthesis, and <br />dissemination of research, not only in the Colorado River Basin, but to a broader <br />audience as well. <br />~ • There is a fundamental need for an assessment tool that will measure progress <br />toward recovery. The current ISMP is not adequate for this purpose. <br />• Knowledge of carrying capacity could help set realistic expectations on recovery <br />targets. <br />~ • Recovery plans for each species should specify the number of populations needed <br />for recovery, their location, and target size. The current IMO targets should be <br />considered preliminary. <br /> <br /> <br />r <br /> <br />viii <br /> <br />
