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 کاملProteomic analysis of proteins associated with body mass and length in yellow perch, Perca flavescens.
The goal of commercial yellow perch aquaculture is to increase muscle mass which leads to increased profitability. The accumulation and degradation of muscle-specific gene products underlies the variability in body mass (BM) and length observed in pond-cultured yellow perch. Our objective was to apply a combination of statistical and proteomic technologies to identify intact and/or proteolytic ...
متن کاملSpatial variation in population density across the geographical range in helminth parasites of yellow perch Perca flavescens
The abundance of a species is not constant across its geographical range; it has often been assumed to decrease from the centre of a species’ range toward its margins. The central assumption of this ‘‘favourable centre’’ model is tested for the first time with parasites, using different species of helminth parasites exploiting fish as definitive hosts. Data on prevalence (percentage of hosts th...
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 ...
