A total of 236 Black Carp were collected throughout the year from 2017-2019 by incidental captures of commercial fishers and biologists. Capture date, river basin of capture location, and coordinates were recorded for each Black Carp captured. A subsample of 119 Black Carp varying from 429-1268 millimeters total length were compared for the precision of annuli counts by two experienced readers for the ossified two anterior pectoral fin rays, the ossified anterior dorsal fin ray, sectioned vertebrae, and lapilli otoliths for selection of a single structure based on percent exact agreement, coefficient of variation, and age-frequency plots.

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...

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 the fish’s (550 millimeter total length) pharyngeal teeth when the fish attempted to crush and consume the clam. Suitable vial size was tested for encapsulating piscicide and two attachment materials, aquarium epoxy and ultraviolet light (UV) cured attachment material. Toxic baits consisting of antimycin A piscicide were...
