Genetic Variation Among Geographically Disparate Yellow Perch Broodstock Populations
… revealed by microsatellite DNA was evaluated in yellow perch, Perca flavescens, from four wild North American populations collected in 2003-2004 (Maine, ME; New York, NY; North Carolina, NC; and Pennsylvania, PA), and two captive populations (Michigan, MI; Ohio, OH). For the loci examined, levels …

Early Life History of Yellow Perch in Eastern South Dakota Lakes
<p>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 …

An Evaluation of Yellow Perch Perca flavescens Mortality in South Dakota
… (recruitment, growth, and mortality) of common yellow perch Perca flavescens population types have been previously investigated in South Dakota. Of these dynamic rate functions, mortality is the least understood for yellow perch populations in South Dakota glacial lakes. Total annual mortality …

Reproductive Manipulation and Larval Rearing Techniques of Yellow Perch (Perca flavescens)
… conducted to evaluate the potential of obtaining yellow perch eggs and fry by controlling the reproductive cycle of broodfish and the techniques used to rear the resulting fry. Chapter 1 is a review of literature pertaining to yellow perch culture and related topics. Chapter 2 is a study of yellow …

Population Dynamics and Management of Yellow Perch Populations in South Dakota Glacial Lakes
… relative abundance of three year classes of yellow perch Perca flavescens were monitored from the larval stage until age 1 in six glacial lakes located in eastern South Dakota in order to determine whether year-class strength could be indexed at the larval stage. Variation in annual peak …

Biology of Age-1 and Older Yellow Perch in West-Central Minnesota Lakes
… in fish community dynamics, segments of yellow perch Perea flavescens ecology in west-central Minnesota lakes remain unknown. The objectives of this study were to determine population structure, population dynamics, adult yellow perch seasonal ontogeny in diet, and if age-1 and 2 yellow …

Spatial and temporal population dynamics of yellow perch (Perca flavescens) in Lake Erie
Yellow perch (Perca flavescens) in Lake Erie support valuable commercial and recreational fisheries critical to the local economy and society. The study of yellow perch's temporal and spatial population dynamics is important for both stock assessment and fisheries management. I explore the spatial …

Yellow Perch Production and Harvest Strategies for Semi-Permanent Wetlands in Eastern South Dakota
Natural production and harvest of yellow perch Perca flavescens within small semi-permanent wetlands in eastern South Dakota is highly variable. Many factors have been attributed to variable natural production including lack of suitable spawning habitat, food availability and competition for …

Recruitment of Bluegill and Yellow Perch in Nebraska Sandhills Lakes: Integrating Multiple Life Stages
Bluegill Lepomis macrochirus and yellow perch Perca flavescens are important, native sport fishes to Nebraska Sandhills lakes. Recruitment dynamics of the fish populations within a given community will ultimately structure the fish communities. I conducted a multiple life-stage investigation of …

Seasonal Distributions, Movements, and Habitat use of Adult Yellow Perch in a Simple Basin
Yellow perch Perca flavescens are an important sport and prey fish species in the glacial lakes region of eastern South Dakota. As a result, the biology of yellow perch throughout this region has been well documented. However, no studies have directly examined the movement patterns and habitat use …

Utilization of Soybean Products as Fish-Meal Protein Replacements in Yellow Perch Perca flavescens Feeds
… Particularly for carnivorous species such as Yellow Perch Perca flavescens (Mitchell), alternative plant-based feedstuffs have shown decreased performance compared to FM. Processed (mechanical, chemical, or microbiological) soybean products are of primary interest as alternative feedstuffs due …
