Yellow Perch, Perca flavescens
range, yellow perch, Perca flavescens, are viewed variously as a sport fish, a valuable food fish, an important forage species, or a nuisance trash fish with little commercial or sport value. Attitudes toward yellow perch vary with its relative availability and with historical regional preferences. In much of the midwestern and central Atlantic areas of the United States and in central Canada, ...
متن کاملEvolutionary ecotoxicology of wild yellow perch (Perca flavescens) populations chronically exposed to a polymetallic gradient.
Depending on such factors as the intensity and duration of the exposure, and the genetic diversity and connectedness of the starting population, exposure to elevated metal concentrations can result in population level alterations such as demographic bottlenecks or metal-induced selection. These processes can be revealed using a population genetic approach, and have important implications with r...
متن کاملReproductive development of yellow perch (Perca flavescens) exposed to oil sands-affected waters.
In similar experiments conducted in 1996 and 2009, yellow perch (Perca flavescens) were stocked into two experimental systems: a demonstration lake where oil sands fine tailings were capped with natural water and a lake in a watershed containing bitumen-bearing sodic clays. In both experiments, yellow perch were captured in May from a nearby reservoir and released into the experimental ponds. P...
متن کاملReproductive health of yellow perch Perca flavescens in selected tributaries of the Chesapeake Bay.
Reduced recruitment of yellow perch has been noted for a number of years in certain urbanized watersheds (South and Severn Rivers) of the Chesapeake Bay. Other rapidly developing watersheds such as Mattawoman Creek are more recently showing evidence of reduced recruitment of anadromous fishes. In this study, we used a battery of biomarkers to better document the reproductive health of adult yel...
متن کاملThe 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 ...
