Regulation and modification of large rivers to accommodate human uses have been a root cause of freshwater biodiversity declines. The Missouri River is among the most drastically-altered large river systems in North America, with a series of mainstem impoundments in the upper watershed altering flow characteristics downstream, and channelization throughout the lower river homogenizing instream habitat and reducing off-channel habitat. Precipitation events during the winter and spring 2010-2011 caused flooding of the greatest magnitude and duration since reservoir completion. The large magnitude and long duration of this flood made it unlike any flood in recent history and provided a unique …
Ecology And Management Of Channel Catfish Ictalurus Punctatus And Flathead Catfish Pylodictis Olivaris Populations In The Missouri River, Ne, Cameron Wesley Goble
Ecology And Management Of Channel Catfish Ictalurus Punctatus And Flathead Catfish Pylodictis Olivaris Populations In The Missouri River, Ne, Cameron Wesley Goble

Channel catfish Ictalurus punctatus and flathead catfish Pylodictis olivaris are two of the most important freshwater recreational or commercial species in the United States. Catfish populations in the Missouri River are important resources to the people of Nebraska and surrounding states. The objective of my study was to determine the present status of catfish populations in the Missouri River, Nebraska. Specifically I evaluated population characteristics such as relative abundance, population size and density, size structure, condition, age structure, growth, and mortality. I used a stratified random sampling design and generalized linear mixed modeling approach to assess differences in population characteristics …
