1930-1932 Gill net data from Lake Michigan These data describe the catch and biological data from 363 bottom-set gill-net lifts distributed throughout Lake Michigan (including main basin and Green Bay) between April and November in 1930–1932. Data collected from the R/V Fulmar were recorded in notebooks and are now archived at the U.S. Geological Survey’s Great Lakes Science Center. Each lift included 1–7 gangs of linen gill nets. Each gang comprised 3–5 panels each having a length of 155 m, a height of 1.5 m, and a (stretch-)mesh size of either 60, 64, 67, 70, or 76 mm. The digitization of the Fulmar data notebooks was started in the late 1990s and finished in this study.

Data are sometimes collected from multiple vessels, raising the question of comparability of data collected among vessels. Hydroacoustic data were collected along three cross-lake transects in central Lake Erie in July, 2014 from three different vessels using similar equipment. Several variables derived from hydroacoustic data and fish densities calculated from those variables were compared between the standard vessel used typically for hydroacoustic data collection and two other vessels used occasionally. The data used in those analyses are presented here.

Hydrologic alteration was represented by simulation of streamflow record for a pre-water-withdrawal condition (baseline) without dams or developed land, compared to the simulated recent-flow condition (2008) including withdrawals, dams and altered landscape to calculate a percent-alteration of flow. Biological samples used represent a median condition of the biological community from 1972 to 2010. This study reviewed...

Subsequent surveys revealed CM to be overgrowing the reef benthos, including corals and coralline algae, potentially placing coral ecosystems in the atoll at risk. This prompted the U.S. Fish and Wildlife Service, the lead management agency of the atoll, to remove the shipwreck. Subsequent surveys showed reversal of spread of CM around the ship impact site. We explain patterns of spread of the CM in terms of life history and local currents and show with a pilot study that pulverized bleach may be an effective tool to eradicate CM on a local scale. If applied strategically, particularly...

Assessing lake-wide distribution and abundance of pelagic prey species over time facilitates evaluation of large-scale drivers of fish production while also considering food-web dynamics at a smaller sub-basin scale. Information from this survey will support decision making within an ecosystem-based fishery management framework. In support of binational Great Lakes fishery management,...

The results of this monitoring effort have been used by natural resource management agencies and native American tribes within the Great Lakes basin to evaluate the reproductive health of lake trout. The data in this release are the thiamine concentrations measured in lake trout collected from 1996-2018. Results are reported as total thiamine (nmol/g-egg), collection site, lake, year collected, and reference to the analysis methods.

Remediation sites were sites that had undergone shoreline softening to convert vertical seawalls to sloping banks, reduce water depths, create a gradual transition between shoreline to main channel habitats, and provide structure (e.g., root wads and boulders) for fishes and other aquatic biota. Control sites were other wade-able (less than 1 meter) areas along the St. Clair River where shoreline softening projects had not taken place. Control sites included public beaches and access points to the St. Clair River and generally had limited in-stream...

The powered vessels overtook the USVs in Lakes Huron and Michigan to study fish avoidance of survey vessels during traditional acoustic surveys. The water column was divided into three depth groups (epilimnion, metalimnion, hypolimnion) for analysis. Each drone transect was binned into 30-sec intervals and measured hydroacoustic values were averaged in this region. To compare vessels and drones, parallel overtakes (overtakes where vessel and drone followed the same path) which were ~2 km long, were measured by both platforms and the differences between acoustic measures compared.

Lampricide treatments are cheaper and more effective in watersheds where dams block runs of adult sea lamprey and hence limit the distribution of sea lamprey larvae. However, dams impound water and those without fishways block movement of valued fishes, outcomes that are untenable for some stakeholders. Here, an alternative to physical barriers was tested to block adult sea lamprey; a portable and seasonal non-physical barrier of pulsed direct current that does not impound water, allows fish passage when not operated, and...

Fish were grown and measured under hatchery conditions for up to nine months before being released into Lake Ontario. Weekly measurements of total length, total weight, and morphometrics were recorded for both species to determine growth during their first year of growth for eight separate year-classes, 2012-2019.

On 20190701, two age groups of pallid sturgeon including 771,707 1-day post-hatch (dph) free embryos and 200,786 5-dph free embryos were released in the Missouri River where dispersal in the water column was assessed through 150 miles. Following dispersal, beam trawl sampling of benthic habitats was conducted to verify settlement and quantify the spatial extent of settlement.

Software-generated raw variables used for calculating estimates of hydroacoustic fish densities are presented here. These data are related to a longer-term data set from 2010-2019.

Hatchery-reared rainbow and brown trout are typically fed exclusively on commercially prepared pelleted feeds and have no experience catching or consuming life fish at the time of stocking and yet stocked fish are percieved to present a high predation risk for juvenile native fishes. These data were compiled to allow for a relative comparison of predation effectiveness between hatchery-reared fish and wild fish. Mean numbers of prey fish surviving in replicated overnight laboratory predation trials were quantified.
