Glorioso, B.M., and Waddle, J.H., 2020, Data from a 2015 trapping survey targeting the Gulf Coast Waterdog, Necturus beyeri, in Saint Tammany Parish, Louisiana: U.S. Geological Survey data release,


This dataset provides the data associated with a 2015 project to examine factors affecting the occupancy of Gulf Coast Waterdogs along Bayou Lacombe, Saint Tammany Parish, Louisiana. Data include site locations and distance from headwaters, water data (pH, turbidity, salinity, and depth), and capture data from trap checks. For Necturus beyeri captures, the datatset provides the sex of captures and length and mass measurements. The dataset states whether eggs were visible in females, whether each animal was swabbed for disease and whether tissue was clipped for genetics.

The Gulf Coast Waterdog is an understudied species in ecology, and is listed as a species of greatest conservation need by the Louisiana Department of Wildlife and Fisheries. The data was collected to better inform where Gulf Coast Waterdogs might be found within stream reaches. The data and associated journal article can be used in further studies to target areas and locate additional populations within their range.
