The Impact

White perch (Morone americana), yellow perch (Perca flavescens), and smallmouth bass (Micropterus dolomieui) were acclimated to 5 and 20 °C. There was an increase in ventricle mass relative to body mass in smallmouth bass only following acclimation to 5° C. Maximal in vitro activities of hexokinase, citrate synthase, carnitine acyl CoA transferase (with palmitoyl CoA, palmitoleoyl CoA, and oleoyl CoA as substrates), and total ATPase were assessed in crude heart homogenates. Tissues removed from warm-acclimated animals were tested at 20 and 5 °C; tissues removed from cold-acclimated animals were assessed at 5 °C. Acute temperature transitions were associated with decreases in the activities of hexokinase (Q10 ≈ 1.8), citrate synthase (Q10 ≈ 1.4), and ATPase (Q10 ≈ 1.7). The impact of temperature on carnitine acyl CoA transferases was generally less severe. This suggests that maximal fatty acid oxidation is conserved better than glucose oxidation during a warm to cold transition. Maximal enzyme activities were generally unaffected by the acclimation regime, with the exception of that of carnitine acyl CoA transferase in white perch heart. The substantial increase in carnitine acyl CoA transferase activity when unsaturated CoA derivatives were provided as substrate suggests an increased capacity to oxidize unsaturated fatty acids at low temperature following an acclimation period. Attempts to sustantiate this contention by offering labelled oleic acid to ventricle sheets were thwarted by a high rate of incorporation into the total lipid pool.

Winter Conditions

After 150 d of simulated winter conditions, 71.2% of the white perch (Morone americana) had died at 2.5 °C, while only 11.1% had died at 4.0 °C. For yellow perch (Perca flavescens), 0.8% had died at 2.5 °C, while 17.7% had died at 4.0 °C. For both species, small fish died first. Multiple regression models relating overwinter mortality versus fall total length and winter duration predict 3.3 times greater mortality for white perch versus similar sized yellow perch at winter temperature regimes typical of the Great Lakes region. In laboratory tanks, white perch remained active throughout the winter period, while yellow perch sought cover and rested on or near the bottom of the experimental tanks. As a direct consequence, yellow perch had a lower routine metabolic rate and consumed body energy more gradually than white perch. During their inactive wintering period at 4.0 °C, yellow perch consumed 25.8% less oxygen than white perch. Actual measurements of dry weight loss indicated that yellow perch in the experimental tanks at 2.5 °C consumed 24.6% less dry weight than similar sized white perch. These differences in overwinter behaviour, metabolism, and survival appear to be adequate to account for observed differences in survival of these species in the wild.

Growth Differences

Since the mid-1970's, white perch Morone americana have expanded rapidly, resulting in possible major interactions with the native yellow perch Perca flavescens. We compared the food consumption rates, diet overlap, and growth of white perch and yellow perch from field data collected during 1983–85 and 1987. Food consumption rates were as much as 27% greater in white perch than in yellow perch, and were higher for both species in the central basin than in the western basin. Seasonal diet composition was most alike in summer and less so in spring and fall, when yellow perch ate more benthos or fish than did white perch. Of 48 Schoener index comparisons of diet overlap during a 3-yr period, 52% were significant (> 0.6). Although yellow perch grew faster in the central basin, reflecting the greater consumption rates, white perch did not show the similar large interbasin growth differences.

Analysis of incidence and intensity of infestation of yellow perch, Perca flavescens (Mitchill), by the glochidia of Lampsilis radiata from weekly samples from May to September and single samples in October and November indicate that the two subspecies, Lampsilis radiata radiata and Lampsilis radiata siliquoidea, shed their glochidia in late spring and throughout the summer in the Bay of Quinte, Lake Ontario. Smaller fish are more heavily infested with these glochidia than larger ones. About 50% of the preparasitic glochidia of Lampsilis radiata siliquoidea survived for 12, 70, and 120 h at 20°, 12°, and 10 °C respectively. The parasitic period of the glochidia of L. r. siliquoidea on yellow perch under experimental conditions was 50 days at 15 °C from the May infestation. Yellow perch carried the glochidia for a longer period from an August infestation. All the glochidia recovered 50 days after infestation, both from May and August infestations, had undergone metamorphosis. There was no difference in the degrees of infestation of the different species of fish used in our experiments. Pumpkinseed, Lepomis gibbosus (Linnaeus); rock bass, Ambloplites rupestris (Rafinesque); and white perch, Roccus americanus (Gmelin) lost their infestations in a week. Presumably no metamorphosis took place under these conditions. Black crappie, Pomoxis nigromaculatus (LeSueur); largemouth bass, Micropterus salmoides (Lacepede), smallmouth bass, M. dolomieui Lacepede: and yellow perch carried the infestation till they were killed 20 days later. There was no relationship between the numbers of glochidia (Lampsilis radiata) and copepods, (Ergasilus confusus Bere) on naturally infested yellow perch, nor on rock bass, smallmouth bass, and pumpkinseed which harbored Ergasilus spp. naturally and which were infested with the glochidia of L. r. siliquoidea experimentally.

Species Shifts

The sequence of fish species shifts since the 1930s in the Bay of Quinte is interpreted in terms of climatic changes and the influences of man. Among the latter, eutrophication is judged most important. The marked decrease in large piscivores in both eastern Lake Ontario and the Bay of Quinte as a consequence of these changes resulted in instability, exemplified by the explosions in populations of alewife (Alosa pseudoharengus) and white perch (Morone americana). Nutrients are imported to the bay, from Lake Ontario by way of alewife. This source has increased in the 1970s with the further decline of piscivores, and it brought about a greater fish production in the bay. We conclude that the Bay of Quinte and Lake Ontario interact significantly and should be studied as a single system.Because of its specialized feeding habits, the post-World War II rise of the walleye (Stizostedion vitreum vitreum) was related to events outside the Bay of Quinte, but its later decline was attributable to direct and indirect effects of eutrophication. Yellow perch (Perca flavescens), by contrast, were apparently not affected adversely by severe habitat changes induced by cultural eutrophication.

Prey Selectivity

We conducted prey selectivity experiments by age 0 white perch (Morone americana) and yellow perch (Perca flavescens) in the laboratory. Lake Erie zooplankters were introduced into tanks where both fishes were in single and combined species assemblages. We identified and counted the introduced plankton samples and the contents of fish stomachs after the feeding period. Our results showed no differences in prey consumed within a fish species, whether in single or combined assemblages (ANOVA, p > 0.05). There were a few differences between white perch and yellow perch consumption of each prey taxa (ANOVA); however, the arrays of organisms eaten were not different (MANOVA, p > 0.01). We note that the majority of prey consumed were smaller taxa, which is counter to optimal foraging predictions in relation to prey size, but is consistent with other research on young planktivore prey selectivities.

History Of

A combination of intensified effort and size limit removal in the mid-1960s resulted in exceptional landings of yellow perch, Perca flavescens, from Saginaw Bay. Though gillnet effort increased from insignificance to account for more than half of the annual catch, gillnet catch per unit of effort (CPE) did not decline during the period of intensified fishing (1964–71) despite severe depletion on some grounds. Trapnet landings and CPE peaked in 1966, when the size limit was removed, but by the early 1970s both statistics were only one-third of the 1966 peaks. A fishing-up sequence began in outer Saginaw Bay and the stocks there were depleted. The fishery then shifted to the inner bay, where the stocks also declined, but to a lesser degree. With intensification of the fishery yellow perch growth rate increased, age-groups V–VII were no longer prominent in the catch and females became relatively scarce shortly after attaining vulnerability. The low recruitment of the late 1960s and early 1970s may have been related to the reduced brood stocks.Within the past 35 yr those changes in the fish community which appeared to affect yellow perch most included loss of the walleye, Stizostedion vitreum vitreum, in the 1940s and proliferation of smelt, Osmerus mordax, and alewife, Alosa pseudoharengus, in the 1950s. However, these changes occurred well before the late 1960s, and were probably not involved in the recent yellow perch decline.A comparison of the rate and regularity of the spring warming with the strengths of the strongest and weakest year-classes for the years 1957–75 suggested that spring temperature had an important role in reproductive success.

Overexploitation and collapse of major fisheries raises important concerns about effects of harvest on fish populations. We tested for ecological and evolutionary mechanisms by which harvest could affect exploited fish populations in Lake Erie over the last four decades, over most of which intensive fisheries management was implemented. We did not detect evidence of long-term negative effects of harvest on yellow perch (Perca flavescens), walleye (Sander vitreus), white perch (Morone americana), or white bass (Morone chrysops) populations, either through recruitment success or through alteration of maturation schedules. Current fisheries management in Lake Erie has been relatively successful with respect to minimizing negative harvest effects, such that the dynamics of exploited fish populations in Lake Erie were more strongly affected by environment than harvest. Our study adds to the evidence that effective fisheries management is capable of rebuilding depleted fisheries and (or) maintaining healthy fisheries. Nevertheless, fisheries management needs to move beyond the ecological dimension to incorporate economic, social, and institutional aspects for society to be better assured of the sustainability of fisheries in rapidly changing ecosystems.

Population Dynamics of Yellow Perch (Perca flavescens), Sauger (Stizostedion canadense), and Walleye (S. vitreum vitreum) in Four Main Stem Missouri River Reservoirs

Stizostedion Canadense

Percid populations have generally increased in abundance relative to other groups of fishes in the 15–25 yr four large reservoirs have been operational on the Missouri River in South Dakota. Saugers (Stizostedion canadense) were initially the most abundant percid, but their numbers gradually declined, probably because of the reduction in river spawning habitat and the increase in water clarity. Yellow perch (Perca flavescens) increased to high population levels as the reservoirs filled but later decreased in abundance. Walleye (S. vitreum vitreum) populations were the slowest to develop in the reservoirs, probably because of initial lack of suitable spawning habitat; they later became well established.The yellow perch was one of the most important forage species in the reservoirs, and walleyes and saugers the primary predator and sport fishes. Sportfishing quality 15–25 yr after impoundment was good, but harvest remained low because of the large size of the reservoirs, inadequacy of facilities for anglers, and the relatively sparse human population. Reproductive success was the primary factor regulating the abundance of percids. Year-class strength was primarily determined by climatic rather than biological factors. Above-average precipitation presumably enhanced reproductive success, both directly by increasing the quantity and quality of spawning substrate through higher stream flows and water levels, and indirectly by providing a larger forage supply, thereby apparently reducing predation on young percids, as well as cannibalism.
