Helminth parasites of teleost fish have evolved strategies to evade and manipulate the immune responses of their hosts. Responsiveness of fish host immunity to helminth antigens may therefore vary depending on the degree of host-parasite counter-adaptation. Generalist parasites, infective for a number of host species, might be unable to adapt optimally to the immune system of a certain host spe...
Ecological Interdependence of Pollution, Fish Parasites, and Fish in Freshwater Ecosystems of Turkey
Records of mass fish deaths were found in different data sources for this study. A map Turkey was also realized the first time. We aimed to present a review distribution freshwater ecosystems Turkey, mostly Marmara Region and Aegean Sea Region, where there are intensive industrial agricultural activities. Fish parasites generally occur equilibrium with their hosts natural environments. In which...
The aims of this study were to produce a checklist of the metazoan parasites of fishes from the Celestun coastal lagoon and to determine the degree of faunal similarity among the fishes based on the metazoan parasites they share. A checklist was prepared including all available records (1996-2014) of parasites of marine, brackish water and freshwater fishes of the area. All of these data were i...
Fish are often infected with different blood protozoa of the genera Babesiosoma, Trypanosoma, and Hemogrigarina. These parasites match which infect mammals. A total 120 samples from five fish species (Barbus grypus, Barbus sharpyi, Liza abu, Carasobarbus luteus, Aspius vorax) were collected Khazar River in Ninevah Governorate, Iraq at weekly intervals during period April 2022 to October for det...
The parasites that normally cause fish disease under farming condition possess a direct life cycle with no need to intermediate hosts for dissemination. The ensuing infection can therefore spread rapidly inducing more damaging lesions in the external parts of host especially the gills. In this study, in order to isolate and identify foreign parasites of phytophagous fish in Guilan province, 4 f...
A total of one hundred and twenty Clarias gariepinus comprising 30 dead and 30 live fishes were examined for protozoan parasites infestation, sixty each from the wild and a pond (cultured environment) over a period of six months. Ichthyophthirius multifiliis was the most common protozoan parasites found in C. gariepinus from the wild (River Benue) and cultured (pond) environments. These protozo...
The argulids are an economically important group of crustacean ectoparasites known to be problematic in fish farming operations from both temperate and tropical regions. Argulus japonicus was first described from Japanese fish but is now well established in many parts of the world including Europe. To aid the development of effective chemotheraputants and/or vaccines against these parasites it ...
