Condition of Surgical Acoustic Tag Incisions in Recaptured Lake Erie Walleye (2011-2016) Intracoelomic implantation of electronic tags has become a common method in fishery research, but rarely are fish examined by scientists after release to understand the extent that surgical incisions have healed. Walleye (Sander vitreus) are a valuable, highly-exploited fishery resource in the Laurentian Great Lakes. Here, fishery capture of walleye with internal acoustic transmitters combined with a high reward program provided multiple opportunities to examine photographs and quantify the status of surgical incisions. Walleye (n=926) from reef and river spawning populations in Lake Erie and Lake Huron were implanted with acoustic transmitters during spring spawning events from 2011 to 2016. Incisions were closed...

These data represent the flowline network in the Upper Peninsula Restoration Assessment (UPRA). It is attributed with the number of disconnections (e.g., road crossings) between the reach and Lake Ontario. The more road crossings on a flowline the more disconnected that area is from the lake and the less suitable it will be for restoration. These data help identify the condition of hydrologic separation between potential restoration areas and Lake Ontario. Low numbers represent fewer disconnections, such as culverts, between the reach and the water body requiring no flow network modification...

However, this ability has largely been neutralized as vast areas of coastal wetlands have been isolated behind dikes; while at the same time the Great Lakes continue to suffer from excess phosphorus loading. In this study we used high-frequency measurements of discharge and turbidity to estimate sediment and phosphorus retention in a formerly diked coastal wetland. We found sediment and phosphorus retention to be episodic and highly related to fluctuations in water level. Low water levels in Lake Erie in late 2012 resulted in low retention in the wetland, but...

Understanding this tradeoff in the Karner blue butterfly (Lycaeides melissa samuelis) can inform resource management for this federally endangered species under changing resource distribution and availability. We collected data on adult butterfly densities, larval (wild blue lupine, Lupinus perennis) and adult (nectaring plants) resource densities, and adult resource use. We defined “resource use” as anytime a butterfly was found (resting, crawling, feeding, laying eggs, mating) on a resource. Data were collected in eight habitat patches (10...

Thus, coordinating fishery and water quality management depends on knowledge of fish behavioral responses to habitat change. This data set aims to reduce these knowledge gaps by combining acoustic telemetry detections of a native demersal fish, lake whitefish (Coregonus clupeaformis), along with forecasted abiotic water quality parameters (e.g., temperature and dissolved oxygen) throughout Lake Erie during periods of seasonal hypoxia. Lake whitefish were tagged throughout 2015-2017. Detection locations of tagged lake whitefish were recorded throughout 2017-2018, using the...

The Lake Erie survey examined the food web across a nearshore to offshore gradient, matching the sampling design the preceding USGS studies of the other four Great Lakes (2010-2013).

The telemetry work was coordinated through the Great Lakes Acoustic Telemetry Observation System (GLATOS, https://glatos.glos.us/). Measurements were obtained from digital images of spine thin sections within the zipped file provided, and can be used to understand the age and growth characteristics of tagged Walleye.

Chemical composition of water is required to be able to trace fish migrations or movements to particular rivers or streams. Because water chemistry can change over time due to changes in land use, tectonic movements that alter groundwater pathways, pollution, industrial activity, and potentially other sources, periodic re-assessment of water chemistry is required. Here we present data on concentrations of common elements for several tributary streams to Lake Michigan, Lake Erie, and Lake Ontario collected in 2017 and 2018.
