<br />APPENDIX <br /> <br />NORTHERN PIKE <br />ARTIFICIAL SPAWNING ~ARSH STUDY <br />STEP-DOWN PLAN <br /> <br />1. Determine benefits and costs of northern pike spawning marsh construc- <br />tion and operation for management of lakes where northern pike is a <br />suitable predator and natural recruitment is inadequate. <br />2. Measure the annual increment of capital amortization and document <br />the yearly operation and maintenance costs. <br />3. Develop experimental marshes for highest production at the <br />least cost, consistent with recruitment needs. <br />4. Purchase or lease land for marsh development. <br />5. Select experimental lakes from the Department's survey <br />list with the help of consultations and further field <br />checks, considering suitability for experimental design. <br />5. Determine the best physical and chemical characteristics <br />of artificial spawning marshes. 1/ <br />6. Make physical determinations from literature <br />review and from consultations. <br />6. Refine physical criteria where necessary by field <br />experiments. <br />4. Produce engineering designs for marsh development on <br />acquired lands. <br />5. Determine the best physical and chemical characteristics <br />of artificial spawning marshes. 1/ <br />6. Make physical determinations from literature review <br />and from consultations. <br />6. Refine physical criteria where necessary by field <br />experiments. <br /> <br />~ 1. <br /> 2. <br /> 3. <br /> 4. <br /> 5. <br /> 6. <br /> 7. <br /> 8. <br /> 9. <br /> 10. <br /> 11. <br /> <br />Area relative to lake area and number of <br />marshes per lake. <br />Depth-marsh morphometry. <br />Proximity to receiving lake. <br />Degree of shelter necessary including axis of marsh <br />relative to prevailing wind. <br />Water supply source--diverted stream, direct runoff, <br />pumped from lake or stream. <br />Water quality--pollutants. <br />Marsh watershed--potential for excessive siltation. <br />Drainable or not, and if drainable, should bottom <br />be dry or swampy. <br />Low iron content. <br />Suitability for structural control of water levels, <br />immigration and emigration of adults and trapping <br />of fingerlings. <br />Stability of water level to avoid exposure of eggs <br />and crowding of fry and fingerlings. <br /> <br />17 <br />
