Data collected from a comprehensive set of hydrodynamic experiments conducted with live grass carp eggs and larvae, to evaluate drifting and swimming patterns with 3 different in-stream obstructions: (1) a gravel bump, (2) a single cylinder, and (3) submerged vegetation. The hydrodynamic behavior of eggs and larvae with each obstruction was continuously monitored for about 85 consecutive hours. Transient spatial distributions of the locations of eggs and larvae across the water column were generated for each flow scenario.
Diploid and triploid Grass Carp (Ctenopharyngodon Idella) tagged with acoustic transmitters were observed in Truman Reservoir, Missouri from February 2017 to March 2019 to determine habitat usage in winter. Habitat parameters were measured at used and available sites to model habitat preference. In addition, tagged fish were targeted during removal attempts to determine the efficacy of using tagged Judas Grass Carp in removing wild conspecifics. This dataset includes information on tagged Grass Carp and habitats they selected as well as capture events and characteristics of the wild fish caught during these attempts.
Diploid and triploid Grass Carp (Ctenopharyngodon Idella) tagged with acoustic transmitters were observed in Truman Reservoir, Missouri from January 2017 to October 2019 to determine longitudinal movements potentially associated with spawning. Passive acoustic receivers were deployed throughout the reservoir and its tributaries to monitor fish movements as they traversed up and downstream. This dataset consists of the detections made by passive receivers and those made by manual tracking.
A series of laboratory experiments were conducted to better understand the behavior of grass carp eggs and larvae in moving water in order to develop and implement new strategies for control and prediction of their dispersal and drift at early life stages. Settling velocity and density of a representative sample of eggs were estimated, and three trials of flume experiments with different flow conditions were conducted with live eggs in a temperature-controlled setting with a mobile sediment bed. In these trials, egg and larval stages were continuously analyzed over periods of 80 hours; and eggs and larvae interactions with the flow and sediment bed were monitored and characterized qualitatively and quantitatively....
The data consists of survival, length and weight of grass carp and black carp gavaged with an oral dose of antimycin A in two carriers, corn oil and ethanol.
Black carp Mylopharyngodon piceus and grass carp Ctenopharyngodon idella are morphologically similar species imported from eastern Asia to North America as biological control organisms. Preferred identification methods are coloration and pharyngeal tooth form. Grass carp possess serrated teeth and black carp molariform teeth. Examination of pharyngeal teeth causes extensive damage to a specimen, and is labor and time intensive. Coloration can vary within a species and fades with preservation. We present a suite of external characteristics consisting of a truss network canonical variate analysis of distance measurements among landmarks on the lateral view of the head of each fish, the ratio of head length to mouth...
In this experimental series we studied the swimming capabilities and response of grass carp (Ctenopharyngodon idella) larvae to flow turbulence in a laboratory flume. We compared three different experimental configurations, representing in-stream obstructions commonly found in natural streams (e.g. a gravel bump, a single vertical cylinder, and patches of submerged rigid vegetation). Grass carp larvae (post gas bladder emergence) were introduce to each experimental configuration and subjected to a variety of hydrodynamic forces of different magnitudes and scales. We varied the flow velocities and water depths and found threshold values of turbulent kinetic energy and Reynolds stresses that triggered an apparent...
Invasive Asian carps established in the United States spawn in turbulent water of rivers and their eggs and early larvae develop while drifting in the current. The eggs are slightly denser than water and are held in suspension by water turbulence. The eggs are believed to perish if they settle before hatching. It is thus possible to use egg drift modeling to assess the capability of a river to support survival of Asian carp eggs. Data to populate such models include the physical properties of the assessed rivers, and information on egg size, density, and terminal fall velocity (sinking rates). Herein, we present the physical characteristics of the eggs as a function of post fertilization time. We recorded mean egg...
