The Invasion Of The Exotic Cladoceran Daphnia Lumholtzi To Willard Bay Utah: Alterations Of The Pelagic Food Web., Olivia Lester
Undergraduate Honors Capstone Projects
Willard Bay, a freshwater impoundment of one of the arms of the Great Salt Lake, is shallow, with a mean volume of 9,900 acres and a maximum summer depth of six meters. This reservoir is highly productive, with a mean secchi depth of 4 meters and chlorophyll a concentrations peaking in summer at 9 micrograms per liter.
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 …

Experimental Investigation Of Elemental Incorporation In The Otoliths Of Larval And Juvenile Fish: Implications For Use As Environmental Recorders, Gretchen Bath Martin
Biological Sciences Theses & Dissertations
Innovative techniques for discerning fish stocks, identifying nursery habitats, locating spawning sites, tracing larval transport pathways, and quantifying the degree of population connectivity are required to meet the goals of sustainable management of marine capture fisheries. One of the most promising techniques is the use of elemental signatures in fish otoliths (ear stones), which record valuable life history data and serve as the link between fish and their environment. To validate the assumption that otolith elemental composition is a function of water elemental concentrations, and to address the possible effects of external variables such as temperature and salinity, the composition …
