COMMUNITY STRUCTURE OF THEDACTYLOGYRUS SPECIES ON THE GILLS OF WILD AND CULTRUED CRUCIAN CARP (CARASSIUS AURATUS)
摘要
Abstract
The species and infection levels ofDactylogyrus on the gills of crucian carp (Carassius auratus) were investigated in Liangzi Lake and a fish cultured pond in Shishou city to determine the effects of the culture environment on the community structure of theDactylogyrus species. SixDactylogyrusspecies were identified on the gills of cucian carp in Liangzi Lake, includingDactylogyrus vastator,D. intermedius,D. arcuatus,D. baueri,D. formosus andD. ine-xpeatatus. With exception ofD. inexpectatus, the other five species ofDactylogyrus were also found in the fish cultured pond. The mean abundance ofDactylogyrus specieswas higher in Liangzi Lake than that in the pond. Apart fromD. vastator, the prevalence of other fourDactylogyrusspecies (not including D. inexpeatatus)in Liangzi Lake was higher than that in the fish pond as well. Mean richness, mean number of individual and Brillouin’s index were also higher in Liangzi Lake than that in the fish pond. The dominant species wasD. arcuatus (0.54) in Liangzi Lake whileD. vastator (0.76)in the fish pond. Of the factors affectedDactylogyrus community, such as fish density, population size, light and dissolved oxygen, dissolved oxygen was considered as the most important factor.关键词
