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 …

Spatial and Temporal Variation in Lake Huron Yellow Perch (Perca flavescens) Life History Traits
… simultaneously. In Lake Huron, the yellow perch (Perca flavescens) is managed based on 17 geographic management units; however, it is unknown if management units accurately represent discrete perch groups. Furthermore, it is unclear whether yellow perch population structure changed temporally over …

Utilization of Soybean Products as Fish-Meal Protein Replacements in Yellow Perch Perca flavescens Feeds
… 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 to their …

Comparative Growth of All-Female Versus Mixed Sex Yellow Perch (Perca flavescens) in Recirculating Aquaculture Systems
Nine, production-scale, recirculating aquaculture systems were utilized to compare the growth parameters between all-female and mixed sex yellow perch stocks. Each system was stocked with 455 fish m⁻³ and contained one of three different biofilter types: a rotating biological contactor, a trickling …

Growth Rates of Yellow Perch, Perca Flavescens (Mitchell), in two North Dakota Lakes After Population Reduction with Toxaphene
… overcrowded populations of yellow perch (Perca flavescens). For lack of more efficient remedial measures the use of piscicides has been recommended to reduce the numbers the numbers of the problem species. Relatively low toxaphene concentrations in two North Dakota lakes substantially …

Examination of Direct and Indirect Effects of Legacy Industrial Pollution On Organ Growth in Wild Yellow Perch (Perca flavescens)
To identify new bioindicators of legacy industrial pollution in aquatic ecosystems, I investigated the effects of chronic pollution on organ growth in fish. Specifically, I examined which organs are most sensitive to pollution and whether these changes were prompted by the indirect effects of …

Evaluating the Use of Modified Corn Distillers Grains as a Fish-meal Protein Replacement in Yellow Perch Perca flavescens
… an enhanced nutrient profile. Two Yellow Perch (Perca flavescens) feeding trials evaluated the performance of HP-DG against a fish meal (positive) control and an unconverted DG (negative) control. The first feeding trial evaluated HP-DG’s produced through different processing methods including: …

The influence of embryo incubation temperature on later life aerobic performance of Lake Whitefish (Coregonus clupeaformis) and Yellow Perch (Perca flavescens)
Temperature represents one of the most influential abiotic factors affecting all living organisms. Ectotherms, including fish, can be affected by temperature at the cellular, individual, population, and community levels. In modern times, climate change and thermal pollution pose major threats as …

A Comparison of the Age and Growth of Yellow Perch, Perca flavescens (Mitchill) in Lake Audubon and Lake Sakakawea, North Dakota, 1978
<p>The age and growth of yellow perch, Perca flavescens (Mitchill), were compared in two lakes which are part of a large Missouri River mainstem reservoir. Forty-five and one hundred and two perch were captured from Lake Sakakawea and Lake Audubon, respectively, by using experimental gill nets and …

Chemical, Physical and Sensorial Compositions of Farmed and Wild Yellow Perch (Perca flavescens), Southern Flounder (Paralichthys lethostigma) and Coho Salmon (Oncorhynchus kisutch)
This study compared chemical, physical and sensorial properties of wild and farmed fish. Farmed yellow perch fillets showed higher lipid contents (2.78% vs. 1.39%); softer texture (0.41 J/g vs. 0.53 J/g); whiter color (higher L* and lower b* values); different fatty acid profile (higher n-3/n-6 …

Genetic Variation Among Geographically Disparate Yellow Perch Broodstock Populations
… 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 of …
