morphometric and molecular characterization of dactylogyrus vastator and d. intermedius in goldfish (carassius auratus).goldfish is known to be parasitized by at least seven species of dactylogyrus and considered as one of the most common hosts. dactylogyrus vastator and dactylogyrus intermedius are the dominant species living on the gills of goldfish. however, little information on morphometric characterization is available, which easily causes misidentification. the purpose of this study is to provide comprehensive morphometric and molecular characterization of d. vastator and d. intermedius collected form a fi ...201626779922
intensity of parasitic infestation in silver carp, hypophthalmichthys molitrix.silver carp, hypopthalmichthys molitrix is one of the most economically valuable fish species in bangladesh. however, its production is often hindered by parasite-induced mortality. the present study reports the intensity of parasitic infestation in 216 specimens of h. molitrix collected from different fish markets in rajshahi city, bangladesh. nine different parasite species (trichodina pediculatus, dactylogyrus vastator, ichthyophthirius multifilis, gyrodactylus elegans, lernaea sp., apiosoma ...201223225858
[the influence of insulin on contamination of the common carp cyprinus carpio by the monogenetic fluke dactylogyrus vastator].the influence of insulin on the contamination of the carp cyprinus carpio with the monogenetic fluke dactylogyrus vastator is studied. fishes reacted to the introduction of the hormon by the decrease in the degree of intensity of infection and by the increase in the number of lifeless parasites on gills, by contrast to control fishes and fishes processed with stress hormones (adrenaline and cortisol). we assume that the decrease in the abundance index in live monogenetic fluke and the increase i ...201122141253
effect of exposure to malachite green solution on common carp fry with dactylogyrus vastator (monogenea) five experiments, common carp (cyprinus carpio) fry with dactylogyrus vastator (monogenea) infection of different severity, as well as parasite-free fry, were placed into aquaria containing malachite green solution of 0.5-10 mg/l concentration. most of the fish died within 6 hours. the correlation between the time of death and helminth infection was studied. the experiments demonstrated that in malachite green solution the carp with the heaviest helminth infection died first while the less se ...19957491866
treatment of fish parasites. 1. praziquantel effective against monogenea (dactylogyrus vastator, dactylogyrus extensus, diplozoon paradoxum). 19854082732
treatment of fish parasites. 4. effects of sym. triazinone (toltrazuril) on monogenea.for chemotherapy in fish parasitized by monogeneans, toltrazuril was tested in vivo and in vitro against gill-parasitizing species (dactylogyrus vastator, d. extensus, d. cornu, pseudodactylogyrus anguillae, diplozoon paradoxum, dip. homoion) as well as the skin-parasitizing species gyrodactylus arcuatus. naturally infected fish were incubated at 20 degrees c for 0.3, 1, 2, 3, 4, and 6h in water containing 0.5, 10, 20, 30, and 50 microgram toltrazuril/ml. in general, the damage observed resulted ...19883237675
occurrence of monogeneans on freshwater fishes in iran: dactylogyrus spp. on cultured iranian fishes.thirteen dactylogyrus spp. were found on cultured fishes in five iranian fish farms. besides typical dactylogyrus vastator, specimens with small anchors were often found in goldfish, which were designated as d. vastator forma minor. rutilus frisii kutum, a fish cultured only in iran, was infected by two dactylogyrus spp. during its short period of prerearing in iranian fish farms. all dactylogyrus found are new for the iranian fauna.19902099610
[polymorphism of the median crochets of dactylogyrus vastator nyb., 1924 (monogenoidea) from the crucian carp, carassius carassius l].there are some variations in the dimensions of anchors depending on the age of the host, localisation and number of parasites. to differentiate such close morphological species as d. vastator and d. crassus it has been suggested to take into account, in addition to taxonomic features, the correlation between the anchor ventroapical length and the bend.1976958727
