Demographics Of A Commercially Exploited Population Of Flathead Catfish (Pylodictis Olivaris) In The Wabash River, Cassi Jo Moody-Carpenter
Demographics Of A Commercially Exploited Population Of Flathead Catfish (Pylodictis Olivaris) In The Wabash River, Cassi Jo Moody-Carpenter
Masters Theses
Flathead catfish, Pylodictis olivaris, are a popular game and commercial fish in the Midwestern United States. In the lower 322 km of the Wabash River, flathead catfish are commercially and recreationally harvested by Illinois and Indiana fishers. Current management regulations are different between the two states; Illinois and Indiana have minimum length limits of 381 and 254 mm, respectively. Indiana has proposed changing their minimum length limit to 381 mm and allowing only one fish> 889 mm to be harvested per day. My study examined the current status of flathead catfish in the Wabash River to determine a standardized …
Dietary Ecology Of An Actively-Foraging Snake Species: Coluber Constrictor Foxii, Corissa Pauline Lennon
Dietary Ecology Of An Actively-Foraging Snake Species: Coluber Constrictor Foxii, Corissa Pauline Lennon
Masters Theses
The trophic niche width of a species varies depending on the foraging strategy employed by the individuals within a population. Among reptiles, the niche breadth of many species of snakes is relatively understudied. Within this clade, the genus Coluber includes wide-ranging, actively foraging snakes that have been historically labeled as dietary generalists. The dietary information on Blue Racers (Coluber constrictor foxii) is limited, and little is known about ontogenetic or seasonal differences in the prey species consumed. Additionally, this information is available from gut and fecal content only. In addition to obtaining gut and fecal contents, I employed stable isotope …
Short-Term Responses Of Fish Assemblages To Habitat Restoration In A Small Midwestern Stream, John Leon West
Short-Term Responses Of Fish Assemblages To Habitat Restoration In A Small Midwestern Stream, John Leon West
Masters Theses
Recent efforts to restore stream habitat have become a common practice, yet evaluations of biotic responses to these practices are not as common. I evaluated fish assemblage response to restoration in a reach of Kickapoo Creek, a fourth order stream southwest of Charleston, Illinois. Restoration included 446 meters of bank stabilization, pool scouring keys, and the creation of two artificial riffles. To have a representation of pre-restoration fish assemblages, I sampled four stream reaches of Kickapoo Creek twice before construction of habitat restoration: two control reaches (upstream and downstream) and two restored reaches within a 0.5 km restoration stretch (upstream …
