MORPHOLOGY, MATERIAL AND VIBRATORY PROPERTIES OF THE SWIMBLADDER IN THE CARP, CYPRINUS CARPIO
The carp Cyprinus carpio has a two-chambered swimbladder and excellent hearing. I explored the hypothesis that the anterior chamber, which connects to Weberian ossicles, is adapted for hearing by testing both chambers for material properties. I also determined displacement and auditory responses to …

Microplastics in White Sucker (Catostomus commersonii) and Common Carp (Cyprinus carpio) from the Upper Thames River, Ontario.
… sucker (Catostomus commersonii) and common carp (Cyprinus carpio)—across 11 sites in the Thames River, Ontario. Microplastics were found in 44% of white sucker, ranging from 0-14 particles per fish, and 31% of common carp, ranging from 0-128 particles per fish. Across both species, the number of …

Melanin as an Oto-Protective Pigment in Two Fish Species: <i> Poecilia Latipinna </i> and <i>Cyprinus Carpio </i>
… species (<em>Poecilia latipinna</em> and <em>Cyprinus carpio</em>) were examined, as well as the potential protective role of melanin from acoustical stress. To identify the relationship between fish color morph and inner ear melanin, a spectrophotometric melanin assay was used for dissected …

Isolation of innate immune response genes, expression analysis, polymorphism identification and development of genetic markers for linkage analysis in common carp (Cyprinus carpio)
Since the late 1990s, common carp and koi production enterprises around the world have suffered enormous losses due to a viral disease caused by cyprinid herpesvirus-3 (CyHV-3). Genetic variation in resistance to CyHV-3 infection was observed in different common carp strains, indicating that …

Control of Common Carp in the Heron Lake Watershed, Minnesota
Common carp Cyprinus carpio were radiotracked during the winter of two years in North (83 7 hectares) and South (13 60 hectares) Heron Lakes, Minnesota to monitor survival and behavior in these shallow (maximum depth 1. 5 m), turbid lakes. Winterkill conditions killed four of six radiotagged common …
