Data

This data set includes information on algae community composition and metadata for fish environmental DNA (eDNA) samples collected along the shoreline of southern Lake Michigan in late August 2024. Washed up, floating, and attached algae were collected along shore and in wadable water. Algal community observations were performed by microscopy to determine primary and secondary dominance...

This dataset contains Mysis count and length measurements from vertical whole-column net tows along a depth gradient in Lake Ontario and associated operation data. Sample dates occurred during August 2021 and June, July, and August 2022. Site depths ranged from 70 to 202 meters bottom depth. Sites were sampled using a paired day-night sampling approach. At each visit, the net was lowered...

The data includes dates, places, and times of sampling events for eggs of invasive Grass Carp (Ctenopharyngodon idella) in tributaries to the Great Lakes in 2014, 2023 and 2024. Reference data on locations and dates sampled, gears used, and effort are included. Developmental stages for a subset of undamaged, fertilized eggs are provided. Tables include common fields to allow for...

The data being released were part of a project funded by the Section 40804 Ecosystem Restoration of the Bipartisan Infrastructure Law (PL-117-58) in support of advancing a national revegetation effort. Data included are from a series of DNA degradation experiments targeting the mitochondrial 16S rRNA gene of the European honeybee (Apis mellifera). This study sought to determine how...

This dataset records Cladophora and associated benthic algae, collectively the Cladophora community or submerged aquatic vegetation (SAV), biomass collected during the growing season of 2023 at stations located along the U.S. shoreline of Lakes Michigan, Huron, Erie, and Ontario. It also records a variety of supporting data collected at Cladophora measurement stations. These supporting...

This dataset is the result of coordinated efforts to compile data associated with stocking events for whitefishes and ciscoes (members of the Coregoninae subfamily) of Great Lakes origin. The dataset includes more than 4,700 records associated with coregonine stocking, from over 150 information sources, spanning the years 1870 - 2022. The compiled information includes species, quantities...

Lake sturgeon (Acipenser fulvescens) have experienced large population declines due to overfishing, habitat degradation, and pollution. Due to these factors, lake sturgeon were extirpated in the Maumee River watershed (Ohio, USA). In 2018, a 20-year reintroduction program began that aims to establish a self-sustaining population in the Maumee River. To understand the potential success of...

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...

This data release contains the methodology and results of two field experiments performed in 2024 to better understand how predation impacts detection efficiency of acoustic tags. The first experiment was a static approach focusing on how different tag types, tag power, depth distance to passive receivers, and predation would affect detection efficiency. It utilized both tagged yellow...

Acoustic telemetry is an effective tool for the study of fish survivorship and habitat use. Fish are tagged with acoustic tags and presence data is collected with stationary receivers. This data set contains a total of 69 hatchery tagged juvenile Lake Sturgeon released into the Genesee River, NY in the Fall of 2019 and 2020, along with data for 30 sub-adult Lake Sturgeon field tagged in...

In 2003, a lake sturgeon reintroduction experiment was initiated in the Genesee River, NY. Young-of-year hatchery-reared lake sturgeon were released over multiple years. An assessment of the presence of lake sturgeon was done by systematic gill netting using monofilament nets. This data release is the lake sturgeon catch information collected during the systematic gill netting from 2003...

Data were collected during efforts to remove invasive grass carp (Ctenopharyngodon idella) from the Sandusky River, OH, USA during 2020–2023. The data includes the number of grass carp captured, capture method, total vessel hours, removal effort year, removal effort month, number of non-target species captured, and river kilometer (distance from the river mouth measured in 0.5 kilometer...
