The Northern Glaciated Plains in the upper Midwest United States is a region where fishing generates millions of dollars a year for local and state economies. Maintaining these revenues requires the management of fish populations that are popular and accessible (e.g. boat ramps, public land access) to anglers. Fisheries throughout the world are currently undergoing unprecedented changes to water levels and habitat quality resulting from climate change. The consequences of climate change to Northern Glaciated Plains fisheries are unknown but pose an immediate challenge for resource managers as angler access and opportunities can be jeopardized when: a) boat ramps become inaccessible due to changing water levels,...
To evaluate how bigheaded carps use a restored backwater habitat, their passages into and out of and residency within a backwater was monitored using acoustic telemetry. This dataset describes the results of this study and was used to compare activity of bigheaded carps between species, at a diel scale, among seasons, and how activity related of environmental conditions. Calculation of passages and residency are available in the thesis of Douglas Schultz (Southern Illinois University, 2006).
The dataset and accompanying analysis scripts accompany the article "Bayesian multistate models allow incorporation of spatial dynamics to improve invasive species management". The data are summarized detections from acoustic telemetry receivers (69 KHz) from 353 silver carp (Hypophthalmichthys molitrix) and 170 bighead carp (H. nobilis) surgically implanted with transmitters in the Illinois River, USA. The analysis scripts assess probability of detection, probability of monthly movement between navigation pools on the river, probability of apparent survival, and probability of operable transmitter battery through a Bayesian multistate hidden Markov model.
This dataset was used to evaluate bigheaded carp movement (net and total) between the upper and lower Illinois River and to create a multistate model in Program MARK to estimate movement probabilities among river pools.
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact
