Sauger Population Ecology in Three Missouri River Mainstem Reservoirs
<p>Sauger Sander canadensis populations have experienced widespread declines across much of their range. Factors suspected to contribute to these declines include hybridization, exploitation, loss of spawning areas, and general habitat alterations associated with regulated rivers. Several sauger …

Conservation genetics of sauger in the upper Missouri River drainage
… walleye may play a substantial role in sauger declines throughout the upper Missouri River drainage of Montana and Wyoming. I identified 11 microsatellite loci to detect interspecific hybridization and describe the genetic population structure of sauger. Two major population groupings of …

Thermal impacts on the early life history of Sauger (Sander canadensis)
Sauger (Sander canadensis), a large North American member of the family Percidae, often exhibit sporadic recruitment governed by a variety of biotic and abiotic factors. This episodic reproductive success is emblematic in Percids, as it has been documented across a wide geographic area for multiple …

Food Habits of Walleye and Sauger in Lake Sakakawea, North Dakota
Walleyes Stizostedion vitreum and saugers S. canadense were collected from White Earth Bay, Van Hook Arm, and Snake Creek Bay of Lake Sakakawea, North Dakota, from May to October, 1991. Food habits were determined and compared among sites within species and compared between species within sites. …

Evaluation of Walleye X Sauger Hybrid Introductions in South Dakota Waters
… Stizostedion vitreum and saugeyes (walleye X sauger Stizostedion canadense hybrids) collected from South Dakota lakes. Fishes were collected in early fall by electrofishing in both 1992 and 1993. Walleyes and saugeyes were identified using horizontal starch gel electrophoresis and …

Assessment of Walleye, Sauger, and Black Bass Populations in Lewis and Clark Lake, South Dakota
… strength of walleye Stizostedion vitreum and sauger s. canadense, as indexed by age-0 seine catch per unit effort (CPUE) , and environmental variables were assessed in Lewis and Clark Lake, South Dakota, from 1985 through 1994. Significant (P≤0. 10) correlations between log10 (n+l) age-0 …

Daily ration, feeding periodicity and prey selection of sauger (Stizostedion canadense) in the Ohio River
Predation by saugers was evaluated from stomach contents of 550 saugers collected by gillnetting in the Gallipolis Pool of the Ohio River during June 1980 - August 1981. Abundance of prey items in the river was assessed from seine samples collected at similar sites during the same period. Gizzard …

Productivity and Trophic Interactions in the Missouri River Impoundments
… between foraging patterns of walleye and sauger Sander canadenses, two similar species found throughout the Missouri River impoundments, were examined. Sauger is of particular concern in the Missouri River reservoirs due to population decline throughout the Midwest over the past 50 years. …

Electrophoretic and Morphological Evaluation of Stizostedion Species Collected from Lake Sakakawea, North Dakota
… between walleye Stizostedion vitreum vitreum and sauger S. canadense in Lake Sakakawea, North Dakota were identified electrophoretically using the species-specific marker malate dehydrogenase. Hybrids represented 10% of 279 percids analyzed. Univariate analysis indicated that counts for eight …

Seasonal Variation in Sampling Indices for Fish Populations Collected From the Missouri River Below Fort Randall Dam, South Dakota
… smallmouth buffalo lctiobus bubalus, and sauger Stizostedion canadense. Sampling data were used to calculate relative species composition, size structure, relative weights (Wr), and catch per unit effort (CPUE). These indices were then assessed for seasonal trends. Seasonal fluctuations …

The Contribution of Missouri River Reservoir Side-Channel and Floodplain Habitats to Mainstem Fish Populations: The Effects of Losing Connectivity Between Hipple Lake and Lake Sharpe
… La Framboise, was important for White Bass, Sauger (Sander canadensis), and Walleye (Sander vitreus) natal recruitment and adult use, as well as adult use for Bluegill, Yellow Perch (Perca flavescens), and Largemouth Bass. A stilling basin was important for Yellow Perch and Gizzard Shad. The …

Influence of Saugeye on Black Crappie Populations in Two Northeastern South Dakota Impoundments
… hybrid between walleye Stizostedion vitreum and sauger S. canadense) were introduced into Lakes Richmond and Mina in Brown County, South Dakota. The objectives of this study were to 1) determine relative survival of advanced fingerling saugeyes stocked into Lakes Richmond and Mina, 2) determine …

Relative Survival and Growth of Walleye and Saugeye Fingerlings Stocked in South Dakota Small Impoundments
… vitreum and saugeye (purposeful walleye x sauger Stizostedion canadense hybrids) fingerlings were concurrently stocked at equal densities into five small impoundments in 1997 and 1998 to evaluate relative survival and growth. Prior to stocking, fish were differentially marked with 7 0 0 ppm …

Seasonal Investigation of Native Fishes and Their Habitats in Missouri River and Yellowstone River Backwaters
… as walleye <em>Stizostedion vitreum</em> and sauger <em>S. canadense</em>, were more transient and appeared sporadically. Some native larval fishes, such as blue sucker <em>Cycleptus elongatus</em> and burbot <em>Lota Iota</em>, drifted into and utilized backwater habitats, but not necessarily …

Utility of Walleyes and Saugeyes as Secondary Predators in Small South Dakota Impoundments
… Stizostedion vitreum and saugeye (walleye x sauger S. canadense) fingerlings were concurrently stocked at equal densities into five small impoundments in 1997, 1988, and 1999 to evaluate relative survival, growth and their ability to restructure existing panfish communities. Prior to …
