Evaluation of Brook Trout (Salvelinus fontinalis) Introductions and Re-introductions Into Four Virginia Blue Ridge Mountain Streams
… all trout > 100 mm received a Biomark® 134.2 kHz passive integrated transponder (PIT) tag to identify individual fish upon recapture. Trout were present in all streams almost three years post introductions. Catches decreased across the first four surveys. Young of year catch rates severely …

Seasonal habitat and movement ecology of adult brook trout in a northern Michigan headwater stream
… and implanted with uniquely identified passive integrated transponder (PIT) tags. Mobile PIT antenna surveys were conducted at fine scales of four 35m focal reaches during four survey seasons, and at coarse scales of 31 100 m reaches during two survey seasons. All surveys were conducted …

Distribution, Movement, and Ecology of Etheostoma spilotum (Gilbert), the Kentucky Arrow Darter, in Gilberts Big Creek and Elisha Creek, Red Bird River Basin, Clay and Leslie Counties, Kentucky
… from 23 reaches across those seasons. Utilizing passive integrated transponder (PIT) tags for continuous tracking, movements of 121 KADs ranged from 28-4,078m in both up and downstream directions. Population estimates ranged from 80-1498 individuals but varied depending on stream and season, with …

Using instream stationary antennas to monitor the movements of warm water fishes in a reach of stream bisected by a culvert
… Creek, Paulding County, Georgia. I used 12mm passive integrated transponder tags and four instream stationary antennas to monitor the movements 429 fishes. The antennas redetected 262 of the 429 individuals (61.1%), and 48% of fishes were redetected more than 10 times. The proportion of tagged …

INDIVIDUAL VARIATION IN WINTER BROOK TROUT (SALVELINUS FONTINALIS) MOVEMENT IN A SMALL NORTHERN MICHIGAN STREAM
… and fish over 100 mm were tagged with a Passive Integrated Transponder (PIT). Following tagging, fish were tracked and their locations within the field site were recorded as well as if they were in open water or under ice cover. In the spring of 2018 and 2019, electroshocking surveys were …

Hydraulic and biological aspects of fish passes for dams
… orifices, allows a comparison between the two. Passive Integrated Transponder (PIT) tags together with antennae installed at a weir and an orifice were used to individually monitor the movement of wild spawning salmon passing through the fish pass. The results of the field test are as yet, …

Propagation and monitoring of freshwater mussels released into the Clinch and Powell rivers, Virginia and Tennessee
… the detection of released mussels, I applied Passive Integrated Transponder tags to laboratory-produced juveniles of the endangered Cumberlandian combshell (Epioblasma brevidens) and released them near Brooks Bridge, Powell River. The detection probability increased above 98%. I developed a …

Small water, big potential: farm ponds and their potential for native fish conservation
… Bass. Each minnow was implanted with a passive integrated transponder (PIT) tag. Translocated populations were monitored using stationary and mobile PIT antennas and estimates of apparent survival and probability of detection for each pond were derived from open population mark-recapture …

Bayesian population dynamics modeling to guide population restoration and recovery of endangered mussels in the Clinch River, Tennessee and Virginia
… the populations at Wallen Bend and Swan Island. Passive integrated transponder (PIT) tags were applied in my fieldwork to monitor the translocation efficiency of E. capsaeformis and Actinonaias pectorosa at Cleveland Islands (CRM 270.8). Hierarchical Bayesian models were developed to address the …

Resource use and life history patterns of juvenile Coho and Chinook salmon in an Alaskan estuary
… tidal movement patterns of Coho Salmon. I used passive integrated transponder (PIT) tags and in-channel antennas to assess fish movement in two marsh channels. In the marsh channel that remained fully connected to the main channel at low tide, fish movement was mostly independent of the tidal …

Predicting how the juvenile life-stages of anadromous Atlantic salmon Salmo salar influence their migration phenology and marine survival.
… for their body length and then fitted with a passive integrated transponder (‘PIT’) tag. Each PIT tag has a unique code that allows for each individual fish to later be re-identified on tag detectors and readers. In the spring, the Frome parr metamorphose into ‘smolts’ and commence their …
