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 کاملTwin-screw Extrusion Processing of Vegetable-based Protein Feeds for Yellow Perch (Perca flavescens) Containing Distillers Dried Grains, Soy Protein Concentrate, and Fermented High Protein Soybean Meal
Changing to alternative protein sources supports production of more economic aquafeeds. Two isocaloric (3.06 kcal/g) and isonitrogenous (40% db) experimental feeds for juvenile yellow perch were formulated with incorporation of fermented soybean meal (FSBM) and soy protein concentrate (SPC), each of which were at two levels (0 and 20% db), along with constant amounts of high protein distillers ...
متن کاملTwin-screw Extrusion Processing of Vegetable-Based Yellow Perch (Perca flavescens) Diets Containing Fermented High Protein Soybean Meal and Graded Levels of Distillers Dried Grains with Solubles
A pilot-plant twin screw extrusion study was performed in two twice-replicated trials with the goal of producing vegetable-based protein feeds for juvenile yellow perch. Two isocaloric (3.06 kcal/g) experimental diets were balanced to contain 20% and 40% DDGS, and a constant amount (20 %) of fermented high protein soybean meal (PepSoyGen, PSG), as the fishmeal protein replacers, in combination ...
متن کاملIsolation and Characterization of Novel Microsatellite Markers for Yellow Perch (Perca flavescens)
To perform whole genome scanning for complex trait analysis, we isolated and characterized a total of 21 novel genomic-SSRs and EST-SSRs for yellow perch (Perca flavescens), using the methods of construction of SSR-enrichment libraries and EST database mining of a related species P. fluviatilis. Of 16 genomic-SSR primer pairs examined, eight successfully amplified scorable products. The number ...
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...
