The aim of the study was to develop a data base about the water quality in the Lake of 16 Tishreen Dam through, study was performed to determine of non biotic factors values of water in Lake and infecting FreeLiving fishes with monogenea parasites, and finding a relationship between parasites distribution and environmental conditions changing. 144 Free – living fishes were examined for detectin...

Various anthelmintics belonging to the pharmacolog~cal group of benzimidazoles (oxibendazole, thiabendazole, albendazole, oxfendazole, flubendazole, mebendazole, parbendazole, fenbendazole and triclabendazole) were tested and compared for their In vitro and in vivo activity against an infection of rainbow trout Onchorhynchus myhss by Gyrodactylus. The trout were also observed for signs of toxic...

Gyrodactylus molweni sp. n. is described from the body surface and fins of South African mullet, Chelon richardsonii (Smith, 1846) collected Table Bay Harbour, Cape Town compared to five other species grey mullets globally namely G. zhukovi Ling, 1963 mugili Zhukov, 1970 Planiliza haematocheila (Temminck Schlegel, 1845); mugelus Rawson, 1973 Mugil cephalus L.; curemae Conroy Conroy, 1985 curema...

The gill monogene communities of Pimephales promelas (fathead minnow) in 3 distinct sites on converging streams were investigated from 2004 to 2006 in 3 different seasons. Thirty collections of P. promelas were made in southeastern Nebraska along 3 converging tributaries: Elk Creek (40.88534 ̊N, 96.83366 ̊W), West Oak Creek (40.9082 ̊N, 96.81432 ̊W) and Oak Creek (40.91402 ̊N, 96.770583 ̊W), Lancast...

The present study addresses the effect of varying temperature and host species on the size and shape of the opisthaptoral hard-parts in isogenic strains of Gyrodactylus salaris and G. thymalli. Variation in shape was examined using geometric morphometrics. Since the opisthaptoral hard-parts of Gyrodactylus have few specific landmarks, their shape information mostly being represented by outlines...

The present work was conducted to isolate and identify different parasites from Indian Major Carp (IMC) Catla catla. During the study period the severity of infection and Parasitic Frequency Index (PFI, %) were also estimated in terms of months, seasons and length groups of fishes. For the investigative purpose different districts of West Bengal were selected considering the potential of fisher...

We evaluated the extent to which males and females evolve along similar or different trajectories in response to the same environmental shift. Specifically, we used replicate experimental introductions in nature to consider how release from a key parasite (Gyrodactylus) generates similar or different defence evolution in male vs. female guppies (Poecilia reticulata). After 4-8 generations of ev...
