Habitat Selection And Partitioning Among Darters In Two Tributaries Of The Clinch River, And Stream Restoration Effects On Substrate Profile, Daniel James Walker

Masters Theses

The group of fish referred to as darters is extremely biodiverse. Often, several closely related species will inhabit the same areas of streams, and prior research has investigated how these species may be partitioning the resources in low-order streams in which they are sympatric. The habitat partitioning of darters in two streams in the Clinch River system, Coal and Cove Creeks, was investigated. The study sites were picked due to their involvement in both physical and biological stream restoration efforts within the last several years, including the collection, translocation, and reintroduction of rainbow darters (Etheostoma caeruleum) from reference sites in …

Community Response To Habitat Restoration In Sickle And Bear Creeks, With Emphasis On Mottled Sculpin In Sickle Creek, Jason Andrew Deboer

Masters Theses

Habitat restoration is employed by biologists and managers to improve the natural functionality and value of aquatic resources. Systems suffer impairment from many sources, including excessive fine sediment, which negatively affects substrate composition, channel morphology, aquatic invertebrate habitat, and fish reproduction and recruitment. Primary objectives included monitoring the biophysical response to sediment abatement in the Big Manistee River watershed. Secondary objectives included (1) placing the biophysical response to the restoration in the context of a much larger watershed plan, (2) quantifying seasonal mottled sculpin movement and habitat use in Sickle Creek for 1-year, and (3) determining habitat variables which may …

The Role Of Bowfin, Amia Calva, In Multiple Species Management Plans, Benjamin Jacob Hausmann

Masters Theses

The major challenge to fisheries managers of the 21st century will be to maintain the diversity, not only of fishing opportunity, but also of traditionally non-game and economically unimportant species. With the relatively recent understanding of the importance of ecosystem level management, attention is being focused on native species that were often ignored or eradicated under past management practices. One such fish that has been largely ignored is the bowfin, Amia calva. Ecological data pertaining to bowfin natural history are limited and to date no attempt has been made to integrate bowfin into fisheries management decisions within the species native …

Nutrition Studies Of The Brindled Madtom, Noturus Miurus Jordan, Based On Stomach Content Analysis, Randall Stephen Madding

Masters Theses

Brindled madtoms and small channel catfish (140 mm or less) were examined to determine their food habits and the possibility of competition for food organisms between the two species when collected from the same area.

Two hundred twenty-three brindled madtoms were collected from Polecat Creek (study area I) 3 miles southwest of Ashmore, Coles County, Illinois. The study in Polecat Creek was conducted from July 10, 1967 to June 5, 1968, collections being made approximately every month. Two hundred forty-five brindled madtoms and 140 channel catfish were collected from the Embarras River (study area II) 2 miles south of Charleston, …
