Juvenile growth and survival of heat-shocked triploid hybrid saugeyes, Stizostedion vitreum × S. canadense
Garcia-Abiado, Mary Ann; Lynch, W. E. Jr.; Dabrowski, Konrad; Czesny, Sergiusz; Rinchard, Jacques; Stafford, J. ( 2002 )Triploid hybrid saugeyes may be a desirable stocking alternative because diploid saugeyes are fertile and can compromise the genetic integrity of parental stocks. Four groups of saugeye eggs were heat-shocked 5 min after ... -
Largemouth Bass Predation on Stocked Tiger Muskellunge
Stein, Roy A.; Carline, Robert F.; Hayward, Robert S. ( 1981 )To better understand why stocked esocids survive poorly, we estimated mortality rates of tiger muskellunge(F1 hybrid of female muskellunge Esox masquinongy * male northern pike E. lucius) that were placed into two Ohio ... -
Larval Gizzard Shad Success, Juvenile Effects, and Reservoir Productivity: Toward a Framework for Multi-System Management
Bremigan, Mary T.; Stein, Roy A. ( 1999 )Recruitment success of larval fishes can determine subsequent effects of older life stages on ecosystem structure and function. Because size and abundance of juvenile gizzard shad Dorosoma cepedianum determines, in large ... -
Larval Size and Recruitment Mechanisms in Fishes: Toward a Conceptual Framework
Miller, Thomas J.; Crowder, Larry B.; Rice, James A.; Marschall, Elizabeth A. ( 1988 )Understanding the mechanisms controlling recruitment in fishes is a major problem in fisheries science. Although the literature on recruitment mechanisms is large and growing rapidly, it is primarily species specific. ... -
Life After Death in Lake Erie: Nutrient Controls Drive Fish Species Richness, Rehabilitation
Ludsin, Stuart A.; Kershner, Mark W.; Blocksom, Karen A.; Knight, Roger L.; Stein, Roy A. ( 2001 )We explored the recent (1969–1996) dynamics of fish communities within Lake Erie, a system formerly degraded by eutrophication and now undergoing oligotrophication owing to phosphorus abatement programs. By merging bottom ... -
Linking Bluegill and Gizzard Shad Prey Assemblages to Growth of Age-0 Largemouth Bass in Reservoirs
Garvey, James E.; Stein, Roy A. ( 1998 )Either gizzard shad Dorosoma cepedianum or bluegills Lepomis macrochirus dominate prey assemblages in many small (<100 ha) Ohio reservoirs. Because gizzard shad spawn early in the spring and their offspring grow rapidly, ... -
Linking Landscapes and Food Webs: Effects of Omnivorous Fish and Watersheds on Reservoir Ecosystems
Vanni, Michael J.; Arend, Kristin K.; Bremigan, Mary T.; Bunnell, David B.; Garvey, James E.; Gonzalez, Maria J.; Renwick, William H.; Soranno, Patricia A.; Stein, Roy A. ( 2005 )Ecologists increasingly recognize the need to understand how landscapes and food webs interact. Reservoir ecosystems are heavily subsidized by nutrients and detritus from surrounding watersheds, and often contain abundant ... -
Management Issues and Their Relative Priority within State Fisheries Agencies
Mather, Martha E.; Parrish, Donna L.; Stein, Roy A.; Muth, Robert M. ( 1995 )For researchers and managers to work together for greatest mutual benefit, researchers must understand what issues fisheries managers consider most important. To assess management priorities, we conducted a mail survey ... -
Manipulating Shad to Enhance Sport Fisheries in North America: An Assessment
DeVries, Dennis R.; Stein, Roy A. ( 1990-05 )Manipulating forage fish populations to enhance sport fisheries is a common management practice. Here we review the literature dealing with manipulations of gizzard shad Dorosoma cepedianum and threadfin shad D. petenense ... -
Modeling sources of variation for growth and predatory demand of Lake Erie walleye (Stizostedion vitreum), 1986-1995
Kershner, Mark W.; Schael, Denise M.; Knight, Roger L.; Stein, Roy A.; Marschall, Elizabeth A. ( 1999 )Given the variable nature of the Lake Erie ecosystem, we investigated biotic and abiotic sources of variation for walleye (Stizostedion vitreum) growth, consumption, and population-wide predatory demand. We determined how ... -
Nutrient Cycling by Fish Supports Relatively More Primary Production as Lake Productivity Increases
Vanni, Michael J.; Bowling, Anna M.; Dickman, Elizabeth M.; Hale, R. Scott; Higgins, Karen A.; Horgan, Martin J.; Knoll, Lesley B.; Renwick, William H.; Stein, Roy A. ( 2006 )Animals can be important in nutrient cycling in particular ecosystems, but few studies have examined how this importance varies along environmental gradients. In this study we quantified the nutrient cycling role of an ... -
Optimal energy allocation to ovaries after spawning
Bunnell, David B.; Marschall, Elizabeth A. ( 2003 )For iteroparous organisms in which fecundity is positively related to body size, a trade-off exists between allocation of energy to gonads, thus ensuring some reproductive output, and allocation to somatic growth, thus ... -
Overwinter growth and survival of age-0 largemouth bass (Micropterus salmoides): revisiting the role of body size
Garvey, James E.; Wright, Russell A.; Stein, Roy A. ( 1998 )How large size affects overwinter growth and survival of age-O fish may vary as a function of food, predation, and energetic condition. During two winters in Ohio, we assessed how these factors affected growth and survival ... -
Overwinter Growth and Survival of Largemouth Bass: Interactions among Size, Food, Origin, and Winter Severity
Fullerton, Aimee H.; Garvey, James E.; Wright, Russell A.; Stein, Roy A. ( 2000 )Winter severity (temperature, duration, and photocycle), geographic origin, food availability, and initial body size likely influence growth, survival, and, therefore, recruitment of age-0 largemouth bass Micropterus ... -
Planktivores and Plankton Dynamics: Effects of Fish Biomass and Planktivore Type
Lazzaro, Xavier; Drenner, Ray W.; Stein, Roy A.; Smith, J. Durward ( 1992 )We quantified the effects of planktivore biomass and planktivore type in an experimental mesocosm study of factorial design in which five levels of fish biomass (0-75 g/m3) were cross-classified with two planktivore types: ... -
Potential Regulation of Age-0 Gizzard Shad by Hybrid Striped Bass in Ohio Reservoirs
Dettmers, John M.; Stein, Roy A.; Lewis, Edward M. ( 1998 )Piscivores can control prey populations in north temperate lakes, leading to increased zooplankton and reduced phytoplankton. In reservoirs with gizzard shad Dorosoma cepedianum, an omnivorous planktivore, this cascade ... -
Predation by Pellet-Reared Tiger Muskellunge on Minnows and Bluegills in Experimental Systems
Gillen, Alan L.; Stein, Roy A.; Carline, Robert F. ( 1981-03 )Studies in Wisconsin lakes have shown that stocked tiger muskellunge( F1 hybrids of female muskellunge, Esox masquinongy * male northern pike, E.lucius) reared on live food survive better than those reared entirely on dry ... -
Predation by Tiger Muskellunge on Bluegill: Effects of Predator Experience, Vegetation, and Prey Density
Tomcko, Cynthia M.; Stein, Roy A.; Carline, Robert F. ( 1984 )Many pellet-reared tiger muskellunge (F1 hybrid of female muskellunge Esox masquinongy and male northern pike E. lucius) do not survive stocking in reservoirs dominated by bluegill Lepomis macrochirus prey. Poor survival ... -
Predator-Prey Interaction between Largemouth Bass and Bluegills as Influenced by Simulated, Submersed Vegetation
Savino, Jacqueline F.; Stein, Roy A. ( 1982-05 )Data from the literature suggest that predatory success declines as habitat complexity increases. To explain this phenomenon, we studied the predator-prey interaction between largemouth bass Micropterus salmoides and ... -
Predicting Crappie Recruitment in Ohio Reservoirs with Spawning Stock Size, Larval Density, and Chlorophyll Concentrations
Bunnell, David B.; Hale, R. Scott; Vanni, Michael J.; Stein, Roy A. ( 2006 )Stock-recruit models typically use only spawning stock size as a predictor of recruitment to a fishery. In this paper, however, we used spawning stock size as well as larval density and key environmental variables to ...
