An Assessment Of Night Time And Seasonal Electrofishing In The Lower Wabash River, Eric Christopher Hine
An Assessment Of Night Time And Seasonal Electrofishing In The Lower Wabash River, Eric Christopher Hine
Masters Theses
Large rivers are highly important systems; being exploited both commercially and recreationally. Because of this usage by humans, close monitoring of the ecology of theses rivers is of the utmost importance. The Long-Term Electrofishing project (LTEF) monitors the fish communities of the Illinois, Mississippi, Wabash, and Ohio rivers using day time, pulsed-DC electrofishing during the late Spring through the early Fall each year. Given that previous studies have noted diel and seasonal changes in catch and composition of fish communities, the addition of night time electrofishing may be beneficial to the overarching goals of the LTEF. This study sought to …
Genetic Structure And Diversity Of Channel Catfish (Ictalurus Punctatus) In Three Large Midwestern Rivers, Vaclav Alexei Sotola
Genetic Structure And Diversity Of Channel Catfish (Ictalurus Punctatus) In Three Large Midwestern Rivers, Vaclav Alexei Sotola
Masters Theses
Little information is available regarding the genetic structure and diversity of sportfishes in large rivers, which can be vital to continuing the sustainable exploitation of these fisheries. Additionally, impoundments often have vast impacts on riverine systems. These impacts include altering the flow regime, changing the nutrient load, and preventing migratory fish from reaching their spawning grounds. If fishes are prevented from reaching their spawning grounds, their genetic diversity and structuring could begin to change relative to historic measures, potentially decreasing their fitness and ability to survive. I screened microsatellite loci to assess the genetic population structure and diversity of channel …
Freshwater Mussels (Bivalvia: Margaritiferidae And Unionidae) Of The Buffalo River Drainage, Tennessee, Matthew Philip Reed
Freshwater Mussels (Bivalvia: Margaritiferidae And Unionidae) Of The Buffalo River Drainage, Tennessee, Matthew Philip Reed
Masters Theses
The Buffalo River in Tennessee once hosted a rich population of freshwater mussels. During the 1980s, monitoring efforts demonstrated evidence of drastic declines and extirpation of entire assemblages. Increases in municipal development in the headwater tributaries and agriculture in the main stem of the Buffalo River are suspected causes for mussel community declines throughout the river. In 2011, collection data documented evidence of recovery in the lower Buffalo River. The aims of this project were: 1) to update the status, distribution, and species composition of mussels in the Buffalo River and its major tributaries through qualitative sampling, and 2) to …
