<br />-: <br /> <br />mixing of the species. <br /> <br />2. In evaluating gear effectiveness, you may want to compare size of fish with gear characteristics <br />(e.g., trammel net mesh size). An effective way to do this is to measure body depths offish from <br />the sample and perform a frequency analysis to compare with gear mesh size. Another effective <br />analysis is Chi2; Le., compare actual with expected catches. <br /> <br />3. The observation is noteworthy that the highest numbers of Colorado squawfish in both gravel <br />pits was during spring runoff. These riverside features are important to this and other native <br />fishes. <br /> <br />4. The conclusions and recommendations from this work are excellent. These should be <br />examined closely by the Recovery Program and implemented. Such ideas as requiring 404 <br />pennitees to structure gravel pits in a certain manner can be a valuable benefit to an otherwise <br />intrusive practice. This idea can take other forms; e.g., gravel pits can be structured with islands <br />and standing old-growth trees to provide perching areas for eagles. <br /> <br />Thank you for the opportunity to review the subject report. I appreciate your attention to <br />keeping me involved in the Recovery Program. I also commend you and your staff for being one <br />of the few "beneficiaries" of the Recovery Program that is producing viable and useful report and <br />publications. Keep up the good work! <br /> <br />Sincerely, <br /> <br />~A~~ <br /> <br />" <br />
