Since the 1990s, Lake Erie has experienced resurgent eutrophication due in part to climate change-driven increases precipitation, which have combined with increasingly intensive agricultural practices region produce excessive nutrient runoff into lake. Harmful blooms of cyanobacterium Microcystis aeruginosa ("Microcystis") Erie's western and central basins (WB CB, respectively) been a highly visible consequence this eutrophication, however few studies characterized intra- or interannual...
Zooplankton play a key role in aquatic ecosystems, providing potential top-down control on phytoplankton and linking primary production to higher trophic levels. Thus, knowledge of zooplankton dynamics is fundamental any assessment the impacts human driven rapid environmental change lakes. Lake Erie has undergone eutrophication since 1990s, resulting summer harmful cyanobacterial blooms, dominated by Microcystis aeruginosa, approximately 2003 western basin (WB) 2008 central (CB). The effect...
Abstract Understanding and predicting recruitment, longstanding goals in fisheries science ecology, are complicated by variation the importance of environmental drivers coupled with dynamic nature individual ecosystems. Developing an understanding recruitment from well-monitored stocks offers opportunity to overcome these complexities. We used a systematic literature review, survey, workshop attended professionals expertise Walleye Sander vitreus identify common additional sources (i.e.,...
Abstract Rising temperatures caused by climate change are likely to affect cool‐water and warm‐water fishes differently. Yet, forecasts of anticipated temperature effects on different thermal guilds lacking, especially in freshwater ecosystems. Towards this end, we used spatially explicit, growth rate potential (GRP) models project changes seasonal habitat quality for a piscivore (largemouth bass Micropterus salmoides ), (walleye Sander vitreus ) hybrid (saugeye S. × canadensis two...
Sagittal otoliths are normally deposited as the CaCO 3 polymorph aragonite; however, a proportion of transitions to vaterite during growth. This transition can complicate otolith chemistry analyses, differences in crystalline structure (aragonite or vaterite) causes variation signatures. To address this issue, we introduce method utilize sagittal partially composed for stock discrimination. Using method, determined hatchery origins yearlings from five Lake Erie hatcheries by using Ba, Mg,...
Abstract In Lake Erie, the fishery for steelhead Oncorhynchus mykiss is overwhelmingly dominated by stocking from state agencies in Michigan, New York, Pennsylvania, and Ohio. Managers that stock may become concerned if a sizeable portion of fish they do not return to waters which were released instead stray other states (“state‐straying”). During fall 2009, spring 2010, 2015, we evaluated origin state‐straying adult five annually stocked tributaries Erie. We also investigated spatial...
Abstract Hypoxia induced by eutrophication and high summer temperatures is common in most Midwestern reservoirs, with uncertain effects on resident fishes. To evaluate the potential influence of low dissolved oxygen (DO) high‐temperature conditions habitat quality for three sport fishes (Largemouth Bass Micropterus salmoides , saugeye [Walleye Sander vitreus × Sauger S. canadensis ], White Crappie Pomoxis annularis ), we used spatially explicit bioenergetics models to measure growth rate...
Abstract Gillnetting and radiotelemetry were used to evaluate the reintroduction of Paddlefish Polyodon spathula into Allegheny Reservoir, New York–Pennsylvania. produced 86 total captures over 6,943 h effort in spring early summer 2008–2011. Forty‐four these individuals received implanted radio transmitters tracked from May 2008 August 2011. showed a strong preference for reservoir sections where depths ranged 6 18 m; only one individual was located water greater than m depth. One sexually...
Abstract Saugeye (female Walleye Sander vitreus × male Sauger S. canadensis ) are stocked annually into Ohio reservoirs to maintain popular recreational fisheries. The growth and recruitment of saugeye highly variable among years reservoirs, but the causes this variability not well understood. Using a multi‐year (2004–2019), multi‐reservoir (six reservoirs) data set, we implemented mixed‐effects models an information theoretic approach identify possible predictors poststocking recruitment....
