A Comparison of Seasonal Movement Patterns of Yellow Perch in Simple and Complex Lake Basins

Abstract

Determining the seasonal movement patterns of fish can provide insight into their spawning behaviors, predator–prey interactions, and habitat preferences. To investigate the seasonal movement patterns of adult yellow perch and how they are affected by lake habitat characteristics, we attached ultrasonic transmitters to two length‐groups (210–235 and 250–280 mm total length) of yellow perch from populations inhabiting two temperate lakes differing in habitat diversity and basin morphology. In the simple lake, yellow perch distributions differed between seasons, mean depth and distance from shore being greatest during the summer. The observed seasonal differences were similar between the two length‐groups. In the complex lake, yellow perch depth varied seasonally, the fish occupying deeper waters during the fall and shallower ones during the summer; however, the distance from shore was consistent among seasons. During the spring, males inhabited areas closer to shore than females in the complex lake, whereas the spatial distributions did not differ between sexes in the simple basin. Yellow perch from both lakes displayed similar seasonal variation in activity, movement rates being highest during the fall and lowest during the summer. Movement rates in the simple lake, however, were higher than those in the complex lake during all three seasons, which suggests that the effectiveness of passive sampling gears may vary in response to habitat complexity. These results reveal several seasonal differences in yellow perch habitat use, distribution, and activity in relation to basin complexity that may provide insight for managers considering sampling plans for individual lake types.

Coping with the cold: energy storage strategies for surviving winter in freshwater fish

“…Previous work has demonstrated that lipid cycling occurs in both life stages for several cold water (Arctic char: Finstad et al 2003, brown trout: Berg et al 2000, brook trout: Cunjak and Power 1987 and cool water species (gizzard shad Dorosoma cepedianum: Pierce et al 1980, yellow perch: Newsome and Leduc 1975, walleye: Henderson et al 1996. This finding parallels recent observations that thermal guild is not always strictly connected to winter activity patterns (Radabaugh et al 2010, Baktoft et al 2012, Mulder et al 2018. The relationships between lipid cycling (CV lipid ) and body size (log-transformed maximum total length) across fish species in all life-stages (immature = open symbols, mature = solid symbols) and tissue types (circles = carcass, squares = soma, triangles = muscle).…”

Waterscape genetics of the yellow perch (Perca flavescens): patterns across large connected ecosystems and isolated relict populations

“…Movements of yellow perch after the spawning season largely are dictated by habitat complexity and foraging capacity, with highest seasonal movements during the fall and the lowest in summer (Radabaugh et al . ). Thus, habitat connectivity and the presence of discrete spawning groups may determine the overall genetic structure of yellow perch in a water body.…”

Origins of functional connectivity in a human-modified wetland landscape

“…Depth heterogeneity had a stronger effect on directional clustering of dispersal in shallow marshes than in deeper ones, perhaps because movement resistance was small at all depths experienced in these deeper marshes. Across different types of aquatic systems, fish movement decreases in distance and becomes more directed as spatial complexity of the physical environment increases (current study; Stickler et al 2008;Radabaugh et al 2010;Hitt et al 2011). Spatial means and variation of relevant physical conditions, such as depth or flow, can be used to predict edge permeability and dispersal directions and distances between landscape elements (Fig.…”
