Effective fishery management in large systems relies on understanding how individual stocks contribute to a over spatial and temporal scales. The current conceptual model for of Walleye Sander vitreus Green Bay designates the northern southern parts bay as distinct stocks, with little mixing between fisheries, assumes that both primarily spawn tributaries opposed shoreline or offshore reef area...

The management of introduced fishes, including Walleye Sander vitreus, whether for control or enhancement, requires understanding population dynamics at the invasion front. recently established in Pend Oreille basin, Idaho, threaten existing salmonid-based fish community and associated recreational fishery. Therefore, objectives this study were to describe growth life history characteristics. s...

Two methods were developed for the production of larval fish diets. The first method, microextrusion marumerization (MEM), has been tested in laboratory feeding trials for many years and produces particles that are palatable and water stable. The second method, particle-assisted rotational agglomeration (PARA), produced diets that have lower density than diets produced by MEM. Each method was u...

Mitochondrial (mt) DNA control region sequences were used to test the genetic and phylogeographic structure of walleye Stizostedion vitreum populations at different geographical scales: among spawning sites, lake basins, lakes, and putative glacial refugia in the Great Lakes region. Sequencing 199 walleye revealed nucleotide substitutions and tandemly repeated sequences that varied in copy numb...

Body size governs predator-prey interactions, which in turn structure populations, communities, and food webs. Understanding predator-prey size relationships is valuable from a theoretical perspective, in basic research, and for management applications. However, predator-prey size data are limited and costly to acquire. We quantified predator-prey total length and mass relationships for several...

The aim of this work was to evaluate and compare the color, texture and sensory characteristics of whitemouth croaker (Micropogonias furnieri) surimi and mechanically separated chicken meat (MDCM) surimi-like material (SLM). The whiteness of the MDCM-SLM was higher (P > 0.05) than that from the surimi. Higher breaking force (P < 0.05) and gel strength (P < 0.05) were also observed for the MDCM-...

Otsego Lake (42o 41’N-70o’W) is the headwaters of the glacially-created Susquehanna River valley within the northern Appalachian Plateau. Historically considered oligo-mesotrophic, (Harman et al., 1997) the unauthorized introduction of alewives (Alosa pseudoharengus) in 1986 (Foster 1989) affected the lake, creating changes similar to those of eutrophy (Harman et al. 2002). Efficient planktivor...

BACKGROUND Consumption of fish is promoted as a healthy way to obtain essential fatty acids (EFA) in the diet, yet the risk of ingesting harmful contaminants remains a concern. A recent study concluded that the risk-benefit of consuming fish from the North American Laurentian Great Lakes, which sustain important commercial and recreational fisheries, is currently unclear. We report the fatty ac...

SigmaPCB and p,p'-DDE levels within and among walleye (Stizostedion vitreum) populations were examined to determine how the method of data analysis could influence the interpretation of (i) gender differences and (ii) geographic variation. In the lower Great Lakes (Huron, Erie, and Ontario) whole-body burdens of both contaminants tended to increase with body mass at a faster rate in males than ...

In vivo electronic monitoring systems for underwater applications are promising technologies obtaining information about aquatic animals. State-of-the-art devices constrained by limits on the number of integrated sensors, large dimensions and weight, short device longevity. Here, we report Lab-on-a-Fish: world’s first biotelemetry tag that combines edge computing with wireless sensing in physio...
