The Caspian frisian roach (Rutilus frisii kutum), economically a very important fish species in Iran, is propagated in fishponds, reared into the rivers in fingerling size and then harvested from the Caspian Sea in adult stage. We found six monogenean parasites on the Caspian frisian roach including five Dactylogyrus spp. on fingerlings cultured in fishponds and rivers and two Dactylogyrus spp....

Hematology is an important pathological and diagnostic tool. This paper describes the hematological parameters of 76 specimens of Hoplias malabaricus infested with monogenean parasites, which were collected from two lagoons. The hematological parameters included: erythrocyte count (Er), microhematocrit (Hct), hemoglobin (Hb), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and ...

The monogenean gill parasites of the genus Ancyrocephalus (Creplin 1839; Ancyrocephalidae, Dactylogyridae) are monoxenous parasites of freshwater fish (Ergens 1966; Simkov a et al. 2003; Simkov a, Matejusov a & Cunningham 2006). Adult trematodes locate mainly on the gills of the host, where they produce eggs that are released into the aquatic environment. The eggs hatch into free-living, ciliat...

The actions of known platyhelminth FaRPs on the contractility of whole-worm preparations of the monogenean, Diclidophora merlangi have been examined in vitro for the first time. All of the peptides tested had excitatory effects on the motor activity of the worm. The order of potency for the peptides tested was: YIRFamide > GYIRFamide = RYIRFamide > GNFFRFamide = FLRFamide. However, although YIR...
