Silver Carp (Hypophthalmichthys molitrix) Locations in Earthen Ponds Exposed to Three Acoustic Signals, June though August, 2018
공공데이터포털
This data set includes acoustic telemetry positions for silver carp ranging in total length from 251 to 359 mm (mean = 294 mm) and weight 131 – 427 g (mean = 231 g) tagged with 795-LD transmitters in four earthen ponds at the Columbia Environmental Research Center, Columbia, MO, USA. Positions were monitored using a 16-hydrophone array in each pond before and during a series of trials where fish were exposed to one of three acoustic signals for a length of 30 minutes. Trials occurred from June 11 to August 7, 2018. The telemetry positions were filtered to include 30 minutes before silver carp were exposed to one of three acoustic signals, and 30 minutes during signal playback. This was repeated for five trials with a new lot of fish for each trial, but Trial 4 data were excluded from the dataset due to fish health concerns.

Evidence of Asian carp spawning above a key choke point in the Mississippi River: Data
공공데이터포털
Bighead Carp, Silver Carp and Grass Carp (collectively Asian carp) were introduced to North America in the 1960s and 70s and have established in the lower Mississippi River basin. Previously published evidence for spawning of these species has been limited in the upper Mississippi River to just below Dam 22 (near Saverton, MO). In 2013 and 2014, we sampled ichthyoplankton at 18 locations in the main stem of the upper Mississippi River from Dam 9 through Dam 19 and in four tributary rivers that empty into the Mississippi River (Des Moines, Skunk, Iowa and Wisconsin Rivers). We identified eggs and larvae using morphological techniques and then used genetic tools to confirm species identity. The spawning events we observed often included more than one species of Asian carp and in a few cases included eggs that must have been derived from more than one upstream spawning event. The upstream extent of genetically confirmed Grass Carp was Pool 12, while Bighead Carp and Silver Carp were observed in Pool 16. In all these cases, ichthyoplankton likely drifted downstream for several kilometers prior to collection. As has been observed elsewhere, no eggs or larvae were collected prior to water temperature reaching 17°C and discharge was usually high when eggs or larvae were observed. Several major spawning events were observed in 2013, but not in 2014. Although reproduction appears to be occurring for all three of these species above Dam 19, the recruitment success of these populations is unknown.

Silver Carp (Hypophthalmichthys molitrix) locations in earthen ponds with overhead structure
공공데이터포털
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.
Native Species Response to 100 HP boat motor acoustic stimulus
공공데이터포털
This dataset includes the behavioral fish data needed to assess the responses of Upper Mississippi River fishes to an acoustic stimulus (i.e., playback of a 100 hp boat motor). Native ostariophysians (bigmouth buffalo Ictiobus cyprinellus, channel catfish Ictalurus punctatus, and fathead minnow Pimephales promelas), invasive ostariophysians (bighead carp Hypophthalmichthys nobilis, common carp Cyprinus carpio, grass carp Ctenopharyngodon idella, and silver carp Hypophthalmichthys molitrix), and native non-ostariophysians (American eel Anguilla rostrata, gizzard shad Dorosoma cepedianum, hybrid striped bass Morone saxatilis, lake sturgeon Acipenser fulvescens, and paddlefish Polyodon spathula) were exposed to a playback of a 100 hp boat motor sound in indoor tanks, and their behavior was monitored for negative phonotaxis and changes in behavior.
