Silver Carp (Hypophthalmichthys molitrix) locations in earthen ponds with overhead structure

Data consists of acoustic telemetry positions for silver carp (345:2 plus or minus 17:5 millimeters total length and 377 plus or minus 64:7 grams weight) tagged with 795-LD transmitters (Innovasea Systems Inc., Boston, MA; formerly Hydroacoustic Technology Inc.) in four earthen ponds (dimensions 40 meters X 25 meters; depth 1-2 meters) at the Columbia Environmental Research Center, Columbia, MO, USA. Positions were monitored from September 7 to October 5, 2018 using a 16 hydrophone array in each pond (Model 290 Acoustic Tag Receiver; Innovasea Systems Inc.; formerly Hydroacoustic Technology Inc.). Silver carp positions were examined for expelled transmitters and excluded from the dataset. A 5-meter square floating platform (aka overhead structure) was placed in one of five possible positions in each pond 24 hours before the beginning of each 48-hour trial for fish acclimation. The overhead structure was moved to a new position and fish allowed to acclimate for each of the seven trials.
