Fish Populations of Two Small Impoundments in Northeastern South Dakota
<p>Thirteen species and large standing crops of fish were found in Blue Cloud Abbey Pond and Labolt Pond, South Dakota. Adult population was estimated to be 5184 fish in Abbey Pond and 5016 in Labolt Pond. Composition of the populations differed. Black crappies were most numerous in Abbey Pond; …

Relative Survival and Growth of Walleye and Saugeye Fingerlings Stocked in South Dakota Small Impoundments
… 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 oxytetracycline hydrochloride (OTC) to allow accurate identification of each fish as a walleye (fry mark) …

Geoprocessing Approaches to Delineate Impoundments and Characterize Subcatchments within Kansas Reservoir Drainages
… by having some of the highest densities of small impoundments in the United States. Previous studies have highlighted the potential of impoundments to act as significant sinks for sediment. However, their significance within Kansas reservoir drainages and potential service in mitigating …

Effects of water willow establishment on littoral assemblages in Kansas reservoirs: focus on age-0 largemouth bass
… Coves in three large (>1,800 ha) Kansas impoundments were chosen and half planted with water willow. Sampling was conducted during the summer from 2001 to 2004. I found that water willow coves had more complex habitat as well as higher abundance and diversity of fishes, …

Feeding Ecology and Factors Influencing Growth and Recruitment of Channel Catfish in South Dakota Reservoirs
… Dakota we studied nine South Dakota reservoirs (small impoundments, tributary-storage reservoirs, mainstem Missouri River reservoirs) to 1) identify and quantify Channel Catfish diets and potential predatory effects on the sportfish community, 2) explore abiotic and biotic factors that influence …

Population Dynamics of Largemouth Bass and Panfish in South Dakota Ponds
… electrofishing samples were collected from 13 small impoundments in 1988 to determine relationships between largemouth bass Micropterus salmoides and bluegills Lepomis macrochirus in South Dakota. Largemouth bass catch per hour of electrofishing, defined as catch per unit effort (CPUE) for …

Urban Fisheries in Eastern South Dakota: Assessment of Angler Satisfaction and Fishery Resources
… with populations from managed lakes and impoundments in eastern South Dakota. I also collected water quality and aquatic habitat data to determine if these characteristics are limiting urban largemouth bass populations. Largemouth bass population estimates varied appreciably, ranging from …

Competition Between Age-0 Largemouth Bass And Juvenile Bluegills In A Virginia Pond
… use similarity in a Virginia recreational small impoundment and by experimentally stocking the species sympatrically and allopatrically in 1.0 m cages and monitoring mortality, growth, and resource use. Niche breadth of bluegills in the small impoundment was greater than that of largemouth …

An Assessment of Northern Pike Populations in Small South Dakota Impoundments
… Lepomis machrochirus were studied in three small South Dakota impoundments to determine predator-prey relationships. Densities (number of fish ≥ stock length ha-1) of northern pike within the three ponds ranged from 6 to 20 in 1994 and 10 to 13 in 1995. Density of northern pike was …

Utility of Walleyes and Saugeyes as Secondary Predators in Small South Dakota Impoundments
… 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 stocking, fish were differentially marked on the right or left side with freeze brands or with …

Small water, big potential: farm ponds and their potential for native fish conservation
Small impoundments, particularly farm or agricultural ponds, are often overlooked as potential habitat for native species despite their ubiquity across many human altered landscapes. Farm ponds intermittently connect to streams during floods allowing species exchanges to and from these novel …

Food Habits of Walleye and Saugeye When Stocked as Secondary Predators into Small South Dakota Impoundments
… natural glacial lake and three South Dakota small impoundments. The food habits study of sympatric largemouth bass and walleye populations was conducted in 1998 at Enemy Swim and Byre lakes South Dakota, where South Dakota Game, Fish and Parks (SDGFP) personnel had previously established the …

Import and decomposition of dissolved organic carbon in pre-dams of drinking water reservoirs
… were low. These results underline that also small impoundments with typically low water residence times are hotspots of carbon cycling, significantly altering water quality in dependence of discharge conditions, temperature and trophic status. Further, it highlights that these factors need to …

Natural Reproductive Cycle of Northern Largemouth Bass in the Upper Midwest, with Applications to Off-season Spawning
… across their range, particularly in temperate small impoundment communities, where they regulate panfish size structure and abundance. In South Dakota, largemouth bass reproductive success and recruitment varies among populations, oftentimes yielding high density, slow-growing panfish …

Advanced Largemouth Bass Production and Stock Contribution to Small South Dakota Impoundment Fisheries
… size structure and growth rates of panfish in small impoundments by reducing the number of small individuals through predation. Largemouth bass are also a highly sought‐after sport fish in South Dakota, ranking highly in surveys of anglers and competitive fishing events. Nearly one‐third of …
