Genetic and morphometric differences demonstrate fine-scale population substructure of the yellow perch Perca flavescens: need for redefined management units.

Fine-scale population genetic structure of the yellow perch Perca flavescens in Lake Erie

Discerning the genetic basis underlying fine-scale population structure of exploited native species and its relationship to management units is a critical goal for effective conservation. This study provides the first high-resolution genetic test of fine-scale relationships among spawning groups of the yellow perch Perca flavescens. Lake Erie yellow perch stocks comprise valuable sport and comm...

The landscape genetics of yellow perch (Perca flavescens) in a large fluvial ecosystem.

Landscape genetics is being increasingly applied to elucidate the role of environmental features on the population structure of terrestrial organisms. However, the potential of this framework has been little explored in aquatic ecosystems such as large rivers. Here, we used a landscape genetics approach in order to (i) document the population structure of the yellow perch (Perca flavescens) by ...

Temporal Population Genetic Structure of Yellow Perch Spawning Groups in the Lower Great Lakes

This study tested the hypothesis that the genetic composition of Yellow Perch Perca flavescens spawning groups at specific sites remained consistent among years or age-cohorts; this likely would influence spatial population structure and be important for delineating management units. Previous studies identified that spawning groups genetically differed among locations across fine geographic sca...

CHEMICAL, PHYSICAL AND SENSORIAL DIFFERENCES BETWEEN FARMED YELLOW PERCH (Perca flavescens) FED DIETS VARYING IN PROTEIN CONCENTRATION

On-farm tests show higher production, growth rate and survival of improved yellow perch

in the Proceedings of the World Aquaculture Society Conference. Page 1142. February 22-25, 2013. Nashville. Yellow perch Perca flavescens is a particularly important aquacultural and ecological species in the Great Lakes Region (GLR)and the Midwest USA. The demand for this species has remained very high in the GLR. Due to the relatively slow growth of currently cultured populations of yellow pe...
