Lake Erie Pelagic Prey Fish Community Data, 2022-2023
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. Assessing lake-wide distribution and abundance of pelagic
Laboratory Evaluation of Phototaxis in Cultured Cisco Larvae
Field observations in a Lake Ontario embayment suggested that there is a phototaxic response of larval cisco that changes with development. This switch was verified using cultured cisco in a laboratory environment. These data include counts of cisco larvae at three depth ranges within multiple 95 liter tanks. Each tank of larvae were exposed to one of three different light treatments with three re
Larval fish and water profile data from Lake Huron in 2017
These data consist of larval fish and water profile data collected with a nearshore to offshore transect approach at 9 transects throughout Lake Huron. Larval fish and their stomach contents were identified, enumerated, and measured (if possible) using a dissecting microscope. These data were used to calculate densities of potential fish prey items (what is available in the environment) and compar
Bottom Trawl Catch Alewife Densities and Ages in Lakes Michigan and Huron
This data release provides catch-per-unit-effort (CPUE) data by age-class for alewife (Alosa pseudoharengus) based on bottom trawl surveys from Lake Michigan (1973-2022) or Lake Huron (1976-2004). These data are associated with a study that sought to evaluate whether alewife populations across the Great Lakes are synchronous in their time series.
Grass Carp (Ctenopharyngodon idella) Egg Diameter Estimates from the Huron River (Ohio), 2022
These data include egg diameter estimates from Grass Carp (Ctenopharyngodon idella) eggs collected during bongo net sampling in the Huron River (Ohio; 41.3305, -82.5812) on May 23, 2022 near Milan, Ohio. Egg diameters were estimated from photographs using proportional relationships of pixel lengths with a known length scale bar in millimeters. Given that eggs were not perfectly spherical, egg diam
Traditional and geometric morphometric data describing wild and artificially reared cisco (Coregonus artedi) from lakes Huron and Ontario
These data describe morphometric (body shape) measurements of wild and artificially reared (i.e., raised in a laboratory or fish hatchery) cisco (Coregonus artedi) from lakes Huron and Ontario in the Laurentian Great Lakes. Specifically, this data release includes traditional morphometric data (i.e., measurements of fish specimens) describing wild and artificially reared cisco from Lake Huron, as
Lake Erie Fish Community Data, 2013-2022
Assessing the distribution and abundance of both predator and prey (forage) fish species is a cornerstone of ecosystem-based fishery management, and supports decision making that considers food-web interactions. In support of binational Great Lakes fishery management the objectives of this survey were to: provide estimates of densities of key forage and predator species in the western basin of Lak
Larval and Young of Year Walleye Diets in Western Lake Erie during 2014 and 2019
Lake Erie walleye (Stizostedion vitreum) recruitment fluctuates annually and depends partially on their diet and growth during their first year of life. To determine how age-0 walleye have responded to changes in prey species and abundance, larval and young of year walleye were collected from western Lake Erie in 2019 and 2014. Larval and young of year fish stomachs were extracted and dissected, w
Field Site Locations from Phragmites Bioherbicide 2023 Field Experiment in Southeast Michigan
This dataset represents the locations of experimental plots that were used during the Phragmites Bioherbicide 2023 field experiment. To meet the criteria for selection, a site must have relatively dry soil with no standing water, have two or more large monotypic stands of Phragmites australis, and be easily accessible by vehicle. Experimental plots were created at these sites and one of four treat
Vegetation survey and photointerpretation data for Metzger Marsh, OH, USA (1994-2022)
These datasets represent USGS-led coastal wetland vegetation survey and mapping efforts at Metzger Marsh, part of the Ottawa National Wildlife Refuge (Ohio, USA) along the coast of western Lake Erie between 1994 and 2022. Vegetation quadrat data provide percent cover estimates per sampling quadrat and overall mean percent cover (MPC) values per species by vegetation type from 1994, and 1996-2010.
Root and Shoot Lengths of Rice and Bermuda Grass Seedlings Inoculated with Endophytic Bacteria from Phragmites australis
These data include measurements of root and shoot lengths of Rice (Oryza sativa) and Bermuda grass (Cynodon dactylon) that were inoculated with nine endophytic bacterial isolates. The tabular data represent growth promotion and fungal infection susceptibility information. They also show the infection rate of F. oxysporum on Rice (Oryza sativa), Bermuda grass (Cynodon dactylon) and Annual Bluegrass
Autonomously Collected Benthic Imagery for Substrate Prediction, Lake Michigan 2020-2021
These data consist of down-looking images of Lake Michigan benthos, collected in 2020 and 2021 with an autonomous underwater vehicle (AUV). Information about each image (i.e., latitude, longitude, depth from surface, altitude, roll, pitch, yaw, and creation time) can be found in the associated csv file. Substrate type was divided into 9 classes based on the Coastal and Marine Ecological Classifica
