Using Acoustic Telemetry To Analyze The Impacts Of Common Carp On Wild Rice Restoration, Franklin Zomer
Using Acoustic Telemetry To Analyze The Impacts Of Common Carp On Wild Rice Restoration, Franklin Zomer
All NMU Master's Theses
Wild rice (Zizania palustris) is an important cultural, spiritual, and dietary resource to Lake Superior Ojibwe. Common Carp (Cyprinus carpio) are an introduced species that negatively impact aquatic vegetation through changes in water quality, uprooting of plants, and consumption of seed. Acoustic telemetry was used to document Common Carp movements in Waishkey Bay in the upper St. Marys River, MI where wild rice habitat is present. Exclosures were established to measure the influence of carp presence on wild rice seeding success. Common Carp were observed to spend much of their time in Waishkey Bay but also …
Continuous, Pulsed And Disrupted Nutrient Subsidy Effects On Ecosystem Productivity, Stability, And Energy Flow, Michael J. Weber, Michael L. Brown
Continuous, Pulsed And Disrupted Nutrient Subsidy Effects On Ecosystem Productivity, Stability, And Energy Flow, Michael J. Weber, Michael L. Brown
Natural Resource Management Faculty Publications
Resource pulses and subsidies can supply ecosystems with an important source of nutrients that supports additional productivity at multiple trophic levels. Common carp Cyprinus carpio provide ecosystems with a continuous nutrient subsidy through bioturbation and excretion but may also initiate a nutrient pulse through carcass decomposition. We examined how continuous (common carp foraging and excretion), pulsed (carcass decomposition) and disrupted (carp introduced and then removed) nutrient subsidies differed in their ability to alter nutrient availability, ecosystem productivity and stability and energy flow. Nitrogen and phosphorus availability and primary production were highest in pulsed, intermediate in continuous and lowest for disrupted …
Ecology Of The Missouri River. Progress Report, Dingell-Johnson Project F-75-R-24, Supplement I - Missouri River Creel Survey, Camp Creek To Kansas State Line, 1 April Through 13 October 2006., Gerald Mestl
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
This report describes Missouri River activities and results related to a channelized Missouri River creel survey conducted from 29 March through 10 October 2003. This is the fourth of a planned annual creel survey to be conducted on alternating sections of the channelized Missouri River to measure changes in recreational fishing activity, especially those changes due to large scale habitat restoration efforts. Future reports will contain additional analyses of these data. Anglers spent over 30,000 hours fishing the Missouri River from Camp Creek (rk 883.5) to the Kansas state line (rk 790.2) during the survey period. Effort peaked during the …
Ecology Of The Missouri River: Missouri River Creel Survey, Bellevue Bridge To Camp Creek, 3 April Through 29 May 2004, Gerald Mestl
Ecology Of The Missouri River: Missouri River Creel Survey, Bellevue Bridge To Camp Creek, 3 April Through 29 May 2004, Gerald Mestl
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
The Nebraska Game and Parks Commission's strategic plan has stated the following management goal for the Missouri River: Restore, protect, and maintain the diversity of historic Missouri River habitats, resources, and ecosystem functions in order that present and future generations may enjoy consumptive and non-consumptive outdoor recreational opportunities (NGPC 1996). To accomplish this goal the Nebraska Game and Parks Commission identified the following five objectives: • To restore terrestrial and aquatic floodplain habitat types by 2008. This would include old oxbows, chutes, side channels, sand bars, backwaters, wetlands, and other shallow water habitats. To restore ftows that reflect the natural …
Ecology Of The Missouri River. Progress Report, Dingell-Johnson Project F-75-R-23, Supplement I - Missouri River Creel Survey, Bellevue To Camp Creek, 2 April Through 14 October 2005, Gerald Mestl
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
This report describes Missouri River activities and results related to a channelized Missouri River creel survey conducted from 2 April through 14 October 2005. This is the sixth of a planned annual creel survey to be conducted on alternating sections of the channelized Missouri River to measure changes in recreational fishing activity, especially those changes due to large scale habitat restoration efforts. We returned to the Bellevue to Camp Creek reach in 2005 because we had to cancel the creel on this reach in 2004 after the second creel period due to lack of personnel. Future reports will contain additional …
Ecology Of The Missouri River: Missouri River Creel Survey, Bellevue Bridge To Camp Creek, 30 March Through 11 October 2002. Supplement I, Gerald Mestl
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
This report describes Missouri River activities and results related to a channelized Missouri River creel survey conducted from 30 March through 11 October 2002. This is the third of a planned annual creel survey to be conducted on alternating sections of the channelized Missouri River to measure changes in recreational fishing activity, especially those changes due to large scale habitat restoration efforts. Future reports will contain additional analyses of these data. Anglers spent over 42,000 hours fishing the Missouri River from Bellevue (rkm 967.7) to Camp Creek (rkm 883.5) during the survey period. Effort was steady from late spring (4/27 …

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
This report describes Missouri River activities and results related to a channelized Missouri River creel survey conducted from 31 March through 12 October 2001. This is the second of a planned annual creel survey to be conducted on alternating sections of the channelized Missouri River to measure changes in recreational fishing activity, especially those changes due to large scale habitat restoration efforts. Future reports will contain additional analyses of these data. Anglers spent over 22,000 hours fishing the Missouri River from Camp Creek (rkm 883.5) to the Kansas state line (rkm 790.2) during the survey period. Effort peaked during the …
