Data

This release contains catch, diet composition, and invertebrate community data on six separate sampling events over a 24-Hour period associated with determining the food availability and food selectivity for Swallowtail Shiners, Notropis procne, in Upper Little York Lake, New York.

This dataset is the sixth installment of a yearly connectivity update for forested habitat within the Great Lakes Restoration Initiative's (GLRI) Terrestrial Habitats & Connectivity (TH&C) work group's Pilot Area. The Pilot Area is a region of the northern Great Lakes Basin between Ashland, WI and the Keweenaw Peninsula and is bounded by Lake Superior in the north and the basin boundary...

This dataset is the sixth installment of a yearly connectivity update for open habitat within the Great Lakes Restoration Initiative's (GLRI) Terrestrial Habitats & Connectivity (TH&C) work group's Pilot Area. The Pilot Area is a region of the northern Great Lakes Basin between Ashland, Wisconsin and the Keweenaw Peninsula and is bounded by Lake Superior in the north and the basin...

Since 2005, the U.S. Geological Survey - Great Lakes Science Center's Lake Erie Biological Station (LEBS) has participated in a collaborative, multiagency effort to assess pelagic prey fish populations in the western (WB), central (CB), and eastern (EB) basins of Lake Erie through a combination of hydroacoustic and midwater trawl sampling. Since 2022, a stratified-random sampling...

In order to determine Walleye (Sander vitreus) and Lake Sturgeon (Acipenser fulvescens) production in the lower Black River, New York, data were collected weekly during the spring of 2013-2025. This data release contains the spring sampling data, egg deposition, larval emergence, and density estimates. Density estimates were calculated using egg and larval abundance for both species on...

Escape hatching responses are naturally occurring hatching events where exposure to specific environmental stimulus elicit hatching of fish embryos earlier than observed without an external stimulus. This response can be caused by a variety of environmental stimuli, including rapid increases in water temperature. We conducted this study to understand if a certain level of larval...

Multibeam echosounder surveys can be used to gather a variety of physical lakebed properties including bathymetry, substrate, and habitat characteristics, by comparing the backscatter and signal intensity to ground truth data. Multibeam data collected at shallow depths (

This dataset is comprised of lakebed photographs collected by an autonomous underwater vehicle (AUV) in Lake Michigan, USA. Photos were annotated to identify invasive dreissenid mussels (Zebra and Quagga mussels) for use in machine learning and algorithm development, specifically to train and validate a transformer-based segmentation model (MusselFinder) for automated mussel density...

This data release includes hatchery-origin juvenile Atlantic Salmon (age-1) acoustic telemetry tag detections from the St. Regis and St. Lawrence Rivers in association with a project to experimentally stock Atlantic salmon within the Lake Ontario watershed. Age-1 fish were surgically implanted with Innovasea V9T model acoustic telemetry tags and released in the Spring of 2022, 2023, and...

Individual gill net collection sites for fish community assemblage including Cisco in Southern Lake Ontario Embayments were recorded. Fish community assemblages including Cisco was assessed using multi-panel gill nets fished overnight to determine where Cisco were residing. Total fish community was recorded with observational recording of fish species, fish total length (mm), and water...

Since 2003, an ongoing research project has been conducted in the Genesee River, New York regarding lake sturgeon reintroduction techniques. This project's applied technique involved the release of age-0 hatchery reared juveniles into historic tributary habitat. One goal of this long-term reintroduction project was to document the return of adult lake sturgeon for spawning after more...

Bloater (Coregonus hoyi) are an extirpated deepwater fish species in Lake America (Lake Ontario). A Bloater reintroduction initiative began in 2012; however annual stocking efforts were unable to yield a self-sustaining population in Lake America. Unsuitable spawning habitat was hypothesized as a potential impediment to natural reproduction, due to observations of Dreissenid mussel...
