We tracked Lake Trout and a small number Yellowstone Cutthroat Trout using acoustic telemetry (Vemco VR2W - 69 kHz) receivers and transmitters (Vemco V- series) in Yellowstone Lake from 2011 to 2016. This data set consists of the fish taqgging and recapture information. In total, 470 Lake Trout and 21 Yellowstone Cutthroat Trout were tagged with transmitters. Transmitters were surgically implanted into fish greater 405 mm total length. Fish were captured via line sampleing, anesthetized with Aqui-S, and tagged within a few minutes of capture. After recovering in freshwater for no more than 10 minutes, all tagged fish were released into Yellowstone Lake. While limited, recaptured fish information was reported to us by commercial gill netters working on the lake.

We initiated a project in 2011 to identify lake-wide movement patterns and spawning areas of invasive lake trout in Yellowstone Lake, WY. We implanted acoustic transmitters in lake trout and established a network of stationary telemetry receivers in Yellowstone Lake. Lake Trout tagged with acoustic transmitters (Vemco V - series) were tracked with stationary acoustic receivers (Vemco VR2W - 69 kHz) from 2011 to 2015. The number of active receivers ranged from 17 - 65 as short term goals of the project changed. Coordinates for each detection represent the location of the receiver reading the transmitter. Additionally, detection ranges can vary from apporximately 500 - 1200 meters (but see Vemco.com for more details). In total, the dataset consists of more than 24 million detections from 470 Lake Trout and 21 Yellowstone Cutthroat Trout that were tagged over the course of the study.

Data on the detection range and efficiency of VR2W-69 kHz acoustic receivers (Innovasea Marine Systems Canada Inc., Bedford, Nova Scotia, Canada; https://www.vemco.com/) were collected to guide the development of telemetry studies of the Clear Lake Hitch (Lavinia exilicauda chi), an imperiled fish species endemic to Clear Lake, Lake County, California. The study took place June 21, 2021 through July 01, 2021. Receivers we deployed at distances of 0m, 25m, 50m, 100m, 200m, and 300m from a sentinel test tag. The test tag was deployed for 20 minutes and emitted signals approximately 6-7 times per minute. Data recorded included the total number of signals emitted by the test tag and the number of those signals that were detected by each receiver. Receiver performance was evaluated in five habitat types: nearshore beach, nearshore with dock pilings, nearshore with a rock reinforced bank (riprap), nearshore with submergent aquatic vegetation, and offshore open water. Five evaluations were conducted in each habitat type. Water depth was measured at each receiver. Basic water quality parameters (Temperature °C, Specific Conductance µS/cm, Salinity PSU, DO saturation %, DO concentration mg/L, pH, Depth, Turbidity FNU, and Chlorophyll µg/L) were measured at the 0m, 100m, and 300m distances with a handheld YSI EXO2 Sonde (Yellow Springs Instruments, Yellow Spring, OH).

Data includes grass carp position and sampling data from 2020 to 2022. We used grass carp that were implanted with acoustic transmitters. The position data was generated in Fathom Position from receivers that composed several VEMCO Positioning Systems (VPS). We also queried the Great Lakes Acoustic Telemetry Observation Network (GLATOS) to obtain non-VPS position detections from receivers made from multiple projects across Lake Erie and associated tributaries. Sampling data was downloaded from the grass carp capture database hosted on ArcGIS Online These data contain information such as location of event, time gears were deployed and retrieved, and number of grass carp caught.

Acoustic telemetry is a popular tool for the study of fish spatial ecology. In acoustic telemetry, fish are captured, surgically implanted with an acoustic transmitter or ‘tag’, and then released back into the environment. Networks of autonomous, stationary receivers then are used to track the movements of tagged individuals over long periods of time (> 1 year). Each acoustic receiver records the date, time, and unique transmitter code (or ID) for each acoustic tag detection. This data set contains detection data for 282 acoustic-tagged lake sturgeon that were captured and released into the Detroit River, St. Clair River, and Lake Huron between 2011 and 2015. Movements of acoustic-tagged individuals were tracked in the Detroit and St. Clair rivers, Lake St. Clair, and in lakes Huron and Erie.

This data release contains passive detection of acoustic telemetry tags that were implanted in walleye Sander vitreus to investigate habitat selection in the dimensions of depth and temperature, and seasonal cross-lake migration in Lake Erie. The data also include continuous archive records of temperature and depth that were obtained from tags that were surrendered by fishers who reported recaptures of tagged fish.
