<br />MONITORING <br />~ Razorback sucker and bonytail stocked in Utah will be monitored according to the plan to <br />monitor stocked fish that will be finalized in Fall 2001 (t1DWR, USFWS-Vernal, CSU). This plan <br />will detail the components and methods to effectively monitor all endangered fish stocked under <br />the scope of the RIP. Monitoring of stocked fish will provide information onpost-stocking <br />distnbution, density, growth, and survival. Respective population estimates will provide <br />~ information on how stocked fish are contributing to the adult populations. Monitoring efforts and <br />population estimates will provide information toward further modification of this stocking plan. <br />Effective monitoring of the stocked endangered fish relies upon an accurate marking strategy. <br />UDWR proposed the used of coded-wire tags in the previous stocking plan (Hudson et al. 1999). <br />~ Subsequent use of these tags on large numbers of bonytail has resulted only in the ability to more <br />accurately determine if a captured chub is a bonytaiL Lethal sampling is required to gather ire <br />pertinent information {e.g., year stocked, time of year stocked). PIT tags should be the method of <br />marking for all endangered fish stocked under the scope of the RIP. <br /> <br />RECOMMENDATIONS <br />• Razorback sucker stocking should commence in Fall 2003 following the approach outlined <br />in this plan. <br /> <br />• Bonytail stocking should commence in Fa112002 following the approach outlined in this <br />P~- <br />• Stocking should continue at least five years for razorback sucker and at least seven years <br />~ for bonytail to meet the objectives of this stocking plan. Any objective(s) not achieved at <br />the completion of this plan should be met through an extension of the stocking plan. <br />• Monitoring of stocked fish should commence immediately to continue evaluation of past <br />stocking efforts and to aIlow for refinement of monftoring approach prior to full <br />~ implementation of this plan. <br />• PIT tags should be used to mark all stocked fish. <br />• Results of monitoring efforts should be used to further refine stocking approach (e.g., <br />~ stocking numbers, stocking size, time of year to stock, stocking location, duration of <br />stocking). <br /> <br />~ to <br />
