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 …
