<br />Recommendations <br /> <br />· Increase number of northern pike removed annually in critical habitat <br />Increase the number of riverwide removal occasions each year. ~ <br />Increase the number of samples in high density areas on each sample \ <br />I <br /> <br />occasion. <br /> <br />... / <br /> <br />Extend removal to other seasons. <br /> <br />· Reduce immigration from areas upstream of critical habitat: <br /> <br />Expand juvenile and adult removal to areas upstream of critical habitat. <br /> <br />Tag northern pike in Elkhead and Catamount reservoirs to determine <br /> <br />relative levels of escapement of adults to the river and if necessary, focus <br /> <br />control measures such as screening on the reservoir with the greatest <br /> <br />level of escapement. <br /> <br />· Reduce recruitment from areas upstream of critical habitat <br /> <br />Identify concentrations of young-of-year (YOY) northern pike to determine <br /> <br />the relative contribution of young from reservoir and riverine spawning <br /> <br />areas. This could be accomplished by sampling for young fish in the river <br /> <br />from Catamount Reservoir to the Green River confluence. <br /> <br />Identify and confirm spawning sites associated with YOY concentrations. <br /> <br />Prioritize and direct management at high production areas. <br /> <br />Investigate and implement techniques that limit access of spawning adults <br /> <br />to high production spawning areas. <br /> <br />Block escapement of YOY or eliminate YOY from high production <br /> <br />spawning areas. <br /> <br />ix <br />
