Year-round records of thermal stratification in the Great Lakes are rare, and there few observations during winter. In this paper we analyze temperature data from 13 logger chains over 130 benthic acoustic receivers that were deployed across Lake Ontario for two years. The timing duration fall overturn correlates with local average water depth, shallow sites ( 100 m depths). Likewise, spring warm faster. has partial ice cover, so wind driven mixing stirs column throughout winter inverse is...
In the Laurentian Great Lakes, application of acoustic telemetry to track fish movements has evolved into an important part multi-jurisdictional management. Nevertheless, barriers remain in translating research management or conservation actions. Here, we synthesize literature within Lakes basin explore factors that have contributed successes and failures integrating with needs decision-making processes. Collaboration between researchers managers, facilitated by consistent opportunities for...
Bloater ( Coregonus hoyi), extirpated from Lake Ontario in the 1980s, have been stocked annually since 2012 with limited success re-establishing a self-sustaining population. In this study, hatchery-raised juvenile bloater were tagged acoustic telemetry high-resolution predation tags and over three depths (5, 50, 100 m) 2022 2023 to quantify survival, causes of mortality, movement. Time-to-event modelling generated 3-week survival estimate 38% (31%–46%; 95% confidence interval) across both...
Cisco (Coregonus artedi) have been extirpated from Lake Erie in North America since the 1960s, but they once supported one of largest Laurentian Great Lakes fisheries. Numerous potential impediments to rehabilitation identified, including summer habitat refugia and predation. We used acoustic telemetry investigate thermal use survival hatchery-reared adult cisco Erie. Fish were experimentally released (n = 50 per site) offshore at Dunkirk, New York, eastern basin Huron, Ohio, central basin....

Ann Arbor, MI 48105 fishery managers have the opportunity and expressed interest in reestablishing a native forage base consisting of various forms species within genus Coregonus.

Abstract Acoustic telemetry was used to assess riverine behavior and passage success for prespawn male adult Atlantic salmon Salmo salar in the lower Penobscot River, Maine, 2005 ( n = 10) 2006 25). Only 3 of 10 (30%) 2 25 (8%) tagged successfully passed all three dams between head tide presumed spawning habitat 2006, respectively. Migrants that failed pass second upstream dam frequently fell back into estuary (3 4 2005; 17 23 2006), few reascended Veazie Dam at tide. Fallback associated...
Summary Radio‐tag signals from fixed‐position antennas are most often used to indicate presence or absence of individuals, estimate individual activity levels signal strength variation within an antenna's detection zone. The potential such systems provide more precise information on tag location and movement has not been explored in great detail ecological setting. By reversing the roles that transmitters receivers play localization methods common telecommunications industry, we present a...
Abstract Seasonal and daily vertical activity of lake whitefish Coregonus clupeaformis was studied in Clear Lake, Maine (253 ha), using acoustic telemetry from November 2004 to June 2009. Twenty adult were tagged with tags that had either a depth sensor or both temperature sensors assess habitat use at seasonal resolution. Vertical selection varied seasonally strongly influenced by temperature. Between December April, when the covered ice, surface below 2°C individuals occupied deep areas...
Abstract Understanding the homing behavior of Atlantic salmon Salmo salar is vital to restoration program employed on Penobscot River, Maine. To produce significant adult returns, managers currently stock hatchery‐raised smolts in specific river sections, providing opportunity imprint chemical signals and enabling their return productive spawning rearing habitat as adults. In this study, we used observational evidence from passive integrated transponder telemetry determine whether adults...
Lake sturgeon (Acipenser fulvescens) were once abundantly distributed throughout the Laurentian Great Lakes. However, widespread overharvesting and habitat degradation has diminished their numbers. The lower Niagara River contains one of few remnant lake populations in New York State. This study determined diet adult quantified trophic position a food web dominated by non-native species. Stomach content analysis assessed recent diet, stable isotope (δ 15 N δ 13 C) blood fin tissue carbon...
Abstract Cisco ( Coregonus artedi ) once dominated fish communities in the Laurentian Great Lakes. Restoring abundance and distribution of this species has emerged as a management priority, yet our understanding spawning habitat use is insufficient to characterise needs for these populations assess whether availability suitable could be constraint recovery. We characterised incubating eggs situ across gradients depth substrate types describe used by three Lakes populations. In Chaumont Bay,...
Partial barriers to migration can affect migratory fish population dynamics and be influenced by many biotic, abiotic, anthropogenic factors, including nutritional deficiencies. We investigated how such variables (including a thiamine deficiency) impact fine-scale movement of landlocked Atlantic salmon (Salmo salar) treating returning spawners with observing their attempts climb human-altered, high velocity stretch river using radio telemetry. Multiple re-entries into section, along water...
Recent research suggests contaminants of emerging concern (CECs) are widespread and environmentally relevant concentrations can impact fishes. However, little is known about impacts CECs to long-lived or rare species. The objective this study was characterize CEC in lake sturgeon (Acipenser fulvescens) serum gametes. Blood collected non-lethally from at four lower Great Lakes basin sites: Detroit, upper Niagara, St. Lawrence rivers; additionally, gametes were the River. Samples analyzed for...
Abstract Species distribution models have become widespread in benthic ecology; however, they mostly been applied to marine and lentic systems. In this study, we a maximum entropy model by using remote sensing‐derived environmental variables predict the of 4 major communities dominated Tubificidae, Naididae, Echinogammarus ischnus , Dreissena spp, respectively, lower Niagara River, NY, USA. The showed very good accuracy for with narrow range (Tubificidae Naididae) indicated area under curve...
Abstract As a long-lived, late-maturing species, lake sturgeon Acipenser fulvescens are vulnerable to the bioaccumulation of contaminants, which may impact reproductive physiology. The purpose this study was use nondestructive method investigate relationship between endocrine-disrupting contaminants and sex steroids in from lower Niagara River. We screened blood plasma samples River (n = 63) during April May 2012 for concentrations 17 organochlorine (OC) that affect endocrine function, as...
Understanding trophic interactions is critical for successful resource management. However, studying diet patterns (e.g., spatial and seasonal changes) can require extensive effort. Using individual analyses to interpret may be further complicated by assumptions limitations of the analytical approach. We investigated compared predicted adult lake trout (Salvelinus namaycush) composition using stomach content analysis (SCA), fatty acid (FAS), stable isotope (SIA) individually simultaneously....
