| seasonal occurrence of lernaea cyprinacea on fishes in belews lake, north carolina. | prevalence, abundance, and mean intensity of lernaea cyprinacea were monitored on 3 species of fishes from june 1984 through august 1986 in belews lake, north carolina. copepods were observed parasitizing fishes only during summer, when water temperatures exceeded 25 c. infection levels in mosquitofish (gambusia affinis) and red shiners (notropis lutrensis) were very low, but they were much higher in fathead minnows (pimephales promelas). infection levels do not appear to be related to the size ... | 1991 | 2010869 |
| the suprapopulation dynamics of bothriocephalus acheilognathi in a north carolina reservoir: abundance, dispersion, and prevalence. | a 2 1/2-year study (september 1980-march 1983) of abundance, dispersion, and prevalence of the pseudophyllidean cestode, bothriocephalus acheilognathi, in 3 species of fish (gambusia affinis, notropis lutrensis, and pimephales promelas) was conducted in 3 ecologically distinct areas of a north carolina cooling pond. mean infrapopulation density and prevalence differed by site, season, and species and size of hosts. degree of aggregation and abundance and prevalence of gravid worms differed by sp ... | 1987 | 3656009 |
| susceptibility of representative great lakes fish species to the north carolina strain of spring viremia of carp virus (svcv). | spring viremia of carp virus (svcv) is a notifiable pathogen of the world organization of animal health. since svcv was isolated in lake ontario in 2007, concern has grown about its spread in the great lakes basin and its potential negative impacts on fish species of importance in stock enhancement programs basinwide. the susceptibility of representative fish species from the families cyprinidae (fathead minnow pimephales promelas, golden shiner notemigonus crysoleucas, spotfin shiner cyprinella ... | 2017 | 29072534 |
