The Development And Application Of A Larval Pallid Sturgeon (Scaphirhynchus Albus) Bioenergetics Model, Laura B. Heironimus
Electronic Theses and Dissertations
Pallid Sturgeon Scaphirhynchus albus are native fish of the Missouri and lower Mississippi River basins and currently listed as an endangered species under the Federal Endangered Species Act. As a result of anthropogenic alterations within the Missouri River, including dredging, channelization, and construction of large reservoirs, Pallid Sturgeon reproduction is reduced or eliminated throughout the species range. Due to a lack of wild progeny, little is known of the larval Pallid Sturgeon and their habitat or environmental requirements. To increase knowledge on the larval Pallid Sturgeon’s physiological requirements for growth and survival, the objective of this study was to develop …
Early Life History Of Yellow Perch In Eastern South Dakota Lakes, Shannon Fisher
Early Life History Of Yellow Perch In Eastern South Dakota Lakes, Shannon Fisher
Electronic Theses and Dissertations
Yellow perch Perea flavescens are a popular South Dakota sportfish; however, inconsistent recruitment creates highly variable and unpredictable perch fishery quality. Before fishery managers can begin to develop and assess strategies to stabilize yellow perch recruitment, a better understanding of their early life history is required. I selected two natural lakes with differing yellow perch population types and monitored brood stock, spawning habits, and larval and juvenile life history patterns during 1995 and 1996. Pelican Lake was selected as a representative yellow perch population exhibiting inconsistent recruitment and Pickerel Lake as a population with relatively consistent recruitment. Yellow perch tended …
