Central tendency of relative ingested prey total length (percent of predator total length) consumed across predator total length.
2018Co-Authors: Jereme W. Gaeta, Tyler D. Ahrenstorff, James S. Diana, William W. Fetzer, Thomas S. Jones, Zach J. Lawson, Michael C. Mcinerny, Victor J. Santucci, Jake Vander M. ZandenAbstract:Piscivores evaluated include muskellunge (Esox masquinongy), northern pike (Esox lucius), walleye (Sander Vitreus), largemouth bass (Micropterus salmoides), smallmouth bass (Micropterus dolomieu), and a grouped ‘crappie’ category (P. nigromaculatus and P. annularis). The relative IP50 (50th percentile regression) is shown from the 5th to 95th percentile of observed predator total lengths, which are noted on the top axes of Fig 1. When applicable, we estimated relative IP50 for different prey body shapes: fusiform (dashed lines) and laterally compressed (dotted lines).

ZandenAbstract:Distributions estimated for the 5th (dotted line), 50th (dashed line), and 95th (solid line) percentile of predator total lengths (TL; mm). Piscivores evaluated include muskellunge (Esox masquinongy), northern pike (Esox lucius), walleye (Sander Vitreus), largemouth bass (Micropterus salmoides), smallmouth bass (Micropterus dolomieu), and a grouped ‘crappie’ category (P. nigromaculatus and P. annularis). The predator total lengths correspond to the top axes of Fig 1. Kernel densities at a given predator total length were derived by estimating prey total length with percentile regressions of every percentile from the 1st to the 99th (Table A in S2 Appendix). The modes of the 5th, 50th, and 95th percentile kernel density distributions are shown along the bottom axis as gray circles, triangles, and diamonds, respectively.

Predator and prey fish total lengths (mm) and quantile regression models.
2018Co-Authors: Jereme W. Gaeta, Tyler D. Ahrenstorff, James S. Diana, William W. Fetzer, Thomas S. Jones, Zach J. Lawson, Michael C. Mcinerny, Victor J. Santucci, Jake Vander M. ZandenAbstract:Piscivores evaluated include muskellunge (Esox masquinongy; n = 473), northern pike (Esox lucius; n = 2,233), walleye (Sander Vitreus; n = 18,102), largemouth bass (Micropterus salmoides; n = 1,486), smallmouth bass (Micropterus dolomieu; n = 380), and a grouped ‘crappie’ category (P. nigromaculatus and P. annularis; n = 317). The 1st, 5th, 50th, 95th, and 99th percentile regressions are shown as gray lines. When the appropriate taxonomic resolution and sample size was available, prey fishes were categorized as having fusiform (black points) or laterally compressed (gray points) body shape, otherwise prey fish body shape was unclassified (open points). The 5th, 50th, and 95th percentiles of predator total lengths are shown at the top of each plot and correspond to the range of lengths modeled in Figs 2 and 3 as well as the density distributions in Fig 4.

impact of rainbow smelt osmerus mordax invasion on walleye Sander Vitreus recruitment in wisconsin lakes
Canadian Journal of Fisheries and Aquatic Sciences, 2007Co-Authors: Norman Mercadosilva, Brian M Roth, Greg G Sass, Stephen J Gilbert, Jake Vander M. ZandenAbstract:Rainbow smelt (Osmerus mordax) are invaders of inland lakes in the Laurentian Great Lakes region of North America and have negatively affected native fish populations. Walleye (Sander Vitreus) comprise an important fishery throughout the Great Lakes region and could be affected by rainbow smelt invasions. We test for declines of young-of-the-year walleye (YOY-W) density in 12 of the 26 known rainbow smelt invaded lakes in Wisconsin. Invaded lakes showed significantly lower YOY-W densities than uninvaded lakes during the period 1985–2004. In 94% (17/18) of years, YOY-W densities from invaded lakes were lower than those from uninvaded lakes. Declines (~70%) in YOY-W densities were observed in three lakes with data from before and after rainbow smelt invasion. For 10 invaded lakes with more than two YOY-W density estimates between 1985 and 2004, YOY-W densities averaged 13% below expected densities. Our results demonstrate the potential impacts of rainbow smelt invasion on walleye tribal, commercial, and rec...

using variance structure to quantify responses to perturbation in fish catches
Transactions of The American Fisheries Society, 2017Co-Authors: Tiffany Vidal, James R Jackson, Lars G Rudstam, Brian J Irwin, Tyler Wagner, James R BenceAbstract:AbstractWe present a case study evaluation of gill-net catches of Walleye Sander Vitreus to assess potential effects of large-scale changes in Oneida Lake, New York, including the disruption of trophic interactions by double-crested cormorants Phalacrocorax auritus and invasive dreissenid mussels. We used the empirical long-term gill-net time series and a negative binomial linear mixed model to partition the variability in catches into spatial and coherent temporal variance components, hypothesizing that variance partitioning can help quantify spatiotemporal variability and determine whether variance structure differs before and after large-scale perturbations. We found that the mean catch and the total variability of catches decreased following perturbation but that not all sampling locations responded in a consistent manner. There was also evidence of some spatial homogenization concurrent with a restructuring of the relative productivity of individual sites. Specifically, offshore sites generally becam...

year class variation drives interactions between warm water predators and yellow perch
Canadian Journal of Fisheries and Aquatic Sciences, 2016Co-Authors: William W. Fetzer, James R Jackson, Collin J Farrell, Lars G RudstamAbstract:Walleye (Sander Vitreus), smallmouth bass (Micropterus dolomieu), and largemouth bass (Micropterus salmoides) are common top predators across many north temperate lakes, but no previous analyses have assessed factors driving their combined impact on mortality of a shared prey, yellow perch (Perca flavescens). We estimated consumption dynamics of walleye, smallmouth bass, and largemouth bass during 3 years that differed in age-0 yellow perch year-class strength and evaluated the relative contribution of each predator to age-0 yellow perch mortality, in Oneida Lake, New York, USA. Habitat-specific diet composition and population densities were integrated with temperature and growth rates to parameterize a bioenergetics model and estimate annual consumption of major diet items. Walleye were the dominant predator in both offshore and inshore habitats, while smallmouth bass and largemouth bass were also important inshore predators. Consumption of age-0 yellow perch by all three predators was positively correla...

analysis of prey selection by double crested cormorants a 15 year diet study in oneida lake new york
Transactions of The American Fisheries Society, 2013Co-Authors: Robin L Debruyne, Jeremy T H Coleman, James R Jackson, Lars G Rudstam, Anthony J VandevalkAbstract:Abstract Piscivorous birds, in particular cormorants Phalacrocorax spp., have been reported to cause declines in some fish populations in both Europe and North America, but not in others. This difference may be due to prey selection by cormorants that is further dependent on the composition of the fish assemblage present. We present 15 years of diet data collected from Oneida Lake, New York, where we have previously documented negative effects of double-crested cormorants Phalacrocorax auritus on two fish populations valued by anglers: Walleye Sander Vitreus and Yellow Perch Perca flavescens. The Oneida Lake fish community changed through the study period and this change was reflected in cormorant diet samples. Diet samples were variable based on season and year with Emerald Shiner Notropis atherinoides, Gizzard Shad Dorosoma cepedianum, Lepomis spp., Logperch Percina caprodes, Walleye, and Yellow Perch having the highest overall relative importance. In years when age-0 Gizzard Shad were abundant they dom...

maternal and stock effects on egg size variation among walleye Sander Vitreus stocks from the great lakes region
Journal of Great Lakes Research, 2012Co-Authors: David G Fielder, Lars G Rudstam, Anthony J Vandevalk, Christopher S Vandergoot, Huiyu Wang, Donald W Einhouse, Troy G Zorn, Tomas O HookAbstract:Abstract Fish egg sizes vary intra-specifically among stocks and individuals, and such variation may reflect a combination of maternal and environmental influences. As egg size variation has important implications for individual and population recruitment success, it is useful to quantify egg-size variation and identify potential factors underlying such variation. We evaluated 1) within-stock maternal influences on egg size and 2) the relative elucidatory power of maternal effects versus stock in explaining inter-individual mean egg size based on eggs collected during 2007–2008 from five walleye Sander Vitreus stocks in the North American Laurentian Great Lakes region. We used both linear regression models and classification and regression trees (CART) to describe egg-size variation. Egg size tended to increase with female length and for some stocks was greatest for intermediate maternal ages. However, maternal influences on egg size were relatively low and variable between years. In contrast, stock had a stronger effect; walleye egg-size variation was greater among stocks than within stocks. After controlling for the influence of maternal age and length, we found that egg size was relatively small for fish spawning in Maumee and Sandusky Rivers (western Lake Erie), intermediate in Oneida Lake and Tittabawassee River (Saginaw Bay, Lake Huron), and relatively large in Van Buren Bay (eastern Lake Erie) and Little Bay de Noc (northern Green Bay, Lake Michigan). Such inter-stock differences in maternal influence adjusted egg size appeared to be negatively associated with a system's productivity; suggesting a potential adaptive response of egg size to early life habitat conditions.

estimating walleye Sander Vitreus density gear catchability and mortality using three fishery independent data sets for oneida lake new york
Canadian Journal of Fisheries and Aquatic Sciences, 2008Co-Authors: Brian J Irwin, James R Jackson, Lars G Rudstam, Anthony J Vandevalk, Ted Treska, Patrick J Sullivan, John L ForneyAbstract:We used three long-term data sets (gill nets, trawls, and adult population estimates) for walleye (Sander Vitreus) to simultaneously estimate density, gear catchabilities, and mortality using an age-structured, nonlinear model. Model con- straints included a fixed natural mortality rate and age- and gear-specific but time-invariant catchabilities. Trawl catchabil- ity decreased with age, whereas gillnet catchability increased towards a maximum by age-4. A sensitivity analysis was conducted to investigate how the information content of the different data sets influenced parameter estimates. Estimated catchability values were relatively robust to changes in data weighting. Estimated gillnet catchability values were fairly consistent with those derived from more conventional methods. An additional mortality term was added to reflect double- crested cormorant (Phalacrocorax auritus) predation, and vulnerabilities associated with angling and cormorants were cal- culated using independent length frequency information. Estimated subadult mortality increased and the influence of fish- ing mortality slightly decreased during recent years when double-crested cormorants were abundant and more restrictive size limits were in place. Walleye density in Oneida Lake (New York, USA) in the last decade is estimated to be approxi- mately half of that before 1990.

growth and survival of age 0 walleye Sander Vitreus interactions among walleye size prey availability predation and abiotic factors
Canadian Journal of Fisheries and Aquatic Sciences, 2006Co-Authors: John R H Hoxmeier, Ronald C Brooks, David H. Wahl, Roy C. HeidingerAbstract:We examined the importance of prey availability, predation, and abiotic factors in determining growth and survival of age-0 walleye (Sander Vitreus) across 15 Illinois reservoirs during 7 years. Multiple life stages were examined by stocking walleye at three different size groups: larval (6 mm total length (TL)), small (46 mm TL), and large (100 mm TL). Factors affecting growth and survival of walleye varied depending on walleye size. Growth of small and large walleye increased with benthic invertebrate density. Temperature had a positive effect on larval and small walleye growth but a negative effect on large walleye growth. Prey availability was an important factor for walleye survival across all size groups, whereas temperature affected only larval and large walleye. Juvenile centrarchid density had a negative effect on larval walleye survival, presumably caused by predation. Our best predictive models explained substantial variation in survival for larval (97%), small (57%), and large (83%) walleye. W...

influence of party size and trip length on angler catch rates on oneida lake new york
North American Journal of Fisheries Management, 2007Co-Authors: Anthony J Vandevalk, James R Jackson, Thomas E. Brooking, Scott D. Krueger, Lars G RudstamAbstract:Abstract Angler catch rates have been used to compare angler success in sport fisheries among years or systems, to assess relative fish abundance, and to evaluate management efforts. Understanding the factors that influence angler catch rates is critical for the proper interpretation and application of these data. Information for 10,998 angler trips was collected through an angler diary program conducted during 1994–1998 and direct-contact roving creel surveys conducted during 1997 and 2002–2004 to examine the influences of angler party size and trip length on the catch rates for walleye Sander Vitreus, smallmouth bass Micropterus dolomieu, and yellow perch Perca flavescens at Oneida Lake, New York. Party size and trip length were correlated; therefore, we constructed separate models combining data for year, party size, and trip length to examine the relationship between these factors and the angler catch rate. In both the diary program and the creel survey, the angler catch rates for all species decrease...
