Food web structure of the Lake Superior fish community in 2021–2022 Food web structure of the Lake Superior fish community in 2021–2022
The trophic linkages and ecological requirements of the Lake Superior fish community have not been assessed on a whole lake scale in over a decade. Here, we investigated the trophic dynamics across multiple species and habitat zones of Lake Superior. From April to October of 2021 and 2022, a total of five piscivore, four planktivore, and six benthivore species were collected by region...

The relative influence of geographic and environmental factors on rare plant translocation outcomes The relative influence of geographic and environmental factors on rare plant translocation outcomes
Conservation translocations are an established method for reducing the extinction risk of plant species through intentional movement within or outside the indigenous range. Unsuitable environmental conditions at translocation recipient sites and a lack of understanding of species–environment relationships are often identified as critical barriers to translocation success. However...

Understanding the influence of image enhancement on underwater object detection: A quantitative and qualitative study Understanding the influence of image enhancement on underwater object detection: A quantitative and qualitative study
Underwater image enhancement is often perceived as a disadvantageous process to object detection. We propose a novel analysis of the interactions between enhancement and detection, elaborating on the potential of enhancement to improve detection. In particular, we evaluate object detection performance for each individual image rather than across the entire set to allow a direct...

Fish-assemblage evaluation in the lower Sandusky River, Ohio, following dam removal Fish-assemblage evaluation in the lower Sandusky River, Ohio, following dam removal
The Sandusky River, Ohio, USA, has experienced more than a century of alterations, including dam implementation and removal, causing a cascade of habitat changes. The physical changes in the river led to establishment of several invasive species. Ten hoop-net sampling sites, spaced about 500 m apart were established in the river to monitor fish assemblage and their habitat preferences...

Seasonal spatial ecology of Lake Trout in Lake Erie Seasonal spatial ecology of Lake Trout in Lake Erie
Objective Lake Trout Salvelinus namaycush are native coldwater apex predators that play an important role in maintaining ecosystem functionality and diversity in the Laurentian Great Lakes. Following population collapses, rehabilitation efforts were widely initiated in the Great Lakes to reestablish self‐sustaining Lake Trout populations. Lake Erie may pose a challenge to these...

Decision analysis of Integrated Pest Management: A case study on invasive sea lamprey in the Great Lakes Basin Decision analysis of Integrated Pest Management: A case study on invasive sea lamprey in the Great Lakes Basin
Integrated Pest Management (IPM) provides a powerful framework for addressing threats to human well-being caused by nuisance species including invasives. We examined the hypothesis that adaptive management could erode barriers to IPM implementation by developing a decision-analytic adaptive management framework for invasive sea lamprey (Petromyzon marinus) IPM in the Laurentian Great...

Reconstructing half a century of coregonine recruitment reveals species-specific dynamics and synchrony across the Laurentian Great Lakes Reconstructing half a century of coregonine recruitment reveals species-specific dynamics and synchrony across the Laurentian Great Lakes
Understanding how multiple species and populations vary in their recruitment dynamics can elucidate the processes driving recruitment across space and time. Lake Whitefish (Coregonus clupeaformis) and Cisco (C. artedi) are socioecologically important fishes across their range; however, many Laurentian Great Lakes populations have experienced declining, poor, or sporadic recruitment in...

Electrofishing Sandusky River grass carp spawning grounds may disrupt spawning Electrofishing Sandusky River grass carp spawning grounds may disrupt spawning
Invasive grass carp Ctenopharyngodon idella spawning was confirmed in Lake Erie with the collection of fertilized eggs in the Sandusky River, Ohio in 2015. Managers responded with initiation of adult grass carp removal in 2017. Hydrodynamic modeling revealed a potential spawning location in downtown Fremont, Ohio (41.3455; −83.1110), which was supported by the presence of sexually mature...

Evaluating behavioral responses of spawning-phase Walleyes to odors of rivers and other Walleyes Evaluating behavioral responses of spawning-phase Walleyes to odors of rivers and other Walleyes
Many fish species show a remarkable ability to home to streams for spawning and fishery managers have applied that knowledge to restore or rehabilitate populations of some species. Walleye Sander vitreus show strong homing tendencies and the ability to select their natal river from other streams. The role of olfactory cues has been hypothesized but never tested in Walleye and many...

Fisheries research and monitoring activities of the Lake Erie Biological Station, 2023 Fisheries research and monitoring activities of the Lake Erie Biological Station, 2023
This report presents biomass-based summaries of fish communities in western Lake Erie derived from USGS bottom trawl surveys conducted from 2013 to 2023. Analyses herein evaluated trends in total biomass, abundance of dominant predator and forage species, non-native species composition, biodiversity and community structure. Data from this effort can be explored interactively online and...

Effects of trap funnel and finger design on Sea Lamprey entrance and retention Effects of trap funnel and finger design on Sea Lamprey entrance and retention
Traps are used to catch adult sea lampreys during their upstream migration to estimate their abundance in streams and, in turn, provide a measure of the Sea Lamprey Control Program’s effectiveness. During 2015 and 2016, we experimentally compared two components of sea lamprey trap design: trap entrance funnel type and the presence of retention devices, using side-by-side instream test...

A transferable approach for quantifying benthic fish sizes and densities in annotated underwater images A transferable approach for quantifying benthic fish sizes and densities in annotated underwater images
1. Benthic fishes are a common target of scientific monitoring but are difficult to quantify because of their close association to bottom habitats that are hard to access. Advances in image-acquisition technologies, machine vision, and deep learning have made capturing and quantifying fishes with cameras increasingly feasible. We present a method and open-source software called...
