Black Carp Biology, Assessment, and Control
Black Carp ( Mylopharyngodon piceus ) is the largest of the four non-indigenous carp species, reaching sizes well in excess of 100 pounds. CERC scientists, in cooperation with federal and state partners, are studying the biology, ecology, and behavior of black carp and developing tools to monitor, assess, and control this non-indigenous species.
Early Life History of Bighead, Silver, Black, and Grass Carps
Grass, bighead, black, and silver carps spawn in turbulent rivers and their eggs develop and hatch while drifting downriver. The larvae also have a short period of developing in the drift, and then they must swim from the river and find appropriate low- or no-flow nursery areas. Rivers which are not long enough, turbulent enough, or without nursery areas in the correct locations are not likely to...
Invasive Carp Species Section
Bighead carp ( Hypophthalmichthys nobilis ) and the closely related silver carp ( Hypophthalmichthys molitrix ) (together, the bigheaded carps) and black carp ( Mylopharyngodon piceus ) are rapidly expanding in numbers and distribution in the Mississippi and Missouri River basins.
Tracking radio-tagged Asian Carp with Unmanned Aircraft System
The ability to track fish such as invasive Asian carp is critical in characterizing their habitat, use and movement, spawning locations, feeding habitats, overwinter refugia, and general movement patterns. We anticipate that a UAS-based approach for tracking fish that are radio-tagged will prove effective and used widely.

Intertidal biofilm presence, quantity, nutritional quality, and composition maps derived from AVIRIS-Next Generation 3.7-meter airborne imagery, South San Francisco Bay, California
Microbial biofilm communities are composed of fungi, bacteria, and phytoplankton taxonomic groups (e.g., cyanobacteria, diatoms, and chlorophytes), which inhabit the surface of intertidal mudflats. Such biofilms have critical roles in shorebird diets, mudflat stabilization, primary productivity, and carbon storage. These raster datasets represent the presence, nutritional quality, quantity, pigmen
Evaluation of fish behaviors in response to driven and undriven entanglement nets with emphasis on invasive Silver Carp, Central Missouri, 2015-2016
We used Adaptive Resolution Imaging Sonar (ARIS), which is based on Dual-Frequency Identification Sonar (DIDSON) technology to observe net encounter behaviors of bigheaded carps. Gill nets with four different mesh types (8.9 cm bar mesh) and trammel nets with five different mesh sizes (range 5.1-8.9 cm bar mesh) were evaluated. Net sets were undisturbed, or fish were driven with the noise of the o
Black Carp in North America: a description of range, habitats, date, and methods of reported captures May 2018-October 2022
Black Carp collections (n=534) by commercial fishers, biologists, and recreational anglers from the Mississippi River basin recorded from 2018 to 2022 are reported here. Geographic coordinates, total length (TL), weight, girth, date of capture, sex, and gear were recorded. Total length was measured from the tip of the snout to the longest caudal fin ray with the caudal fin lobes pinched. Girth was

Light trap and larval trawl collection of bigheaded carp in the Missouri River Basin, 2016
In the Lamine, Moreau, and Little Chariton rivers, light traps were used to capture larval bigheaded carps moving into tributaries. Traps were set on a weekly basis in each river, at roughly 1-kilometer intervals up to 7 km upstream. Ichthyoplankton tows were done in locations near the confluence of each tributary with the Missouri River, and within the Missouri River itself. Data includes identif
Black carp (Mylopharyngodon piceus) mouth gape and size preference of a bivalve prey
These data represent the measurements of length and mouth gape from large juvenile and adult wild-caught and small juvenile hatchery origin black carp, and the results of laboratory size preference trials with bivalve prey, specifically Corbicula clams. Wild-caught black carp ranged from 429-1580 mm total length, a larger range than measured in previous studies. Corbicula feeding trial data consis
Size, attachment material and efficacy of piscicide delivery vials and baits for control of black carp, Mylopharyngodon piceus
A piscicide delivery method was designed to selectively target black carp Mylopharyngodon piceus, an invasive species in North America which possesses specially adapted pharyngeal teeth for crushing mollusk prey. Bait was prepared by attaching a glass vial containing toxicant (antimycin A) to the exterior of Corbicula fluminea clam valve. The vial was designed to break by the force exerted from th

Toxic baits are a potential control mechanism for nuisance carps, but rotenone-based baits for grass carp Ctenopharyngodon idella have been ineffective. Failures have been attributed to the palatability of rotenone because innocuous training pellets are readily consumed prior to provision of piscicide baits.
