Argulus siamensis is the most damaging fish parasite prevalent in the freshwater aquaculture systems of India. In an attempt to further understand the behavior of this economically important parasite, the means of biological transmission, egg laying strategies and effect of temperature on development of eggs was studied. A. siamensis showed opportunistic egg laying behavior where in it used bot...

INTRODUCTION Eel is one of the most valuable commercial fish species of the Vistula Lagoon. For this reason its infection by non-indigenous species of parasites is the subject of the interest of sciencists. MATERIAL AND METHODS A total of 90 eel specimens caught in the Polish part of the Vistula Lagoon were examined over the period of May-August 2005. The fish were subjected to standard proce...

occurrence of lernaea parasite in a narrow distributed endemic fish, chondrostoma orientale (oriental nase) restricted to the kor river basin, southwestern iran is reported. based on the obtained results, all three collected specimens (tl= 174-192mm, sl= 148-169mm) were infested with lernaea parasites which were attached to the base of dorsal, pectoral, caudal and pelvic fins and also body musc...

Monogenea is one of the most species-rich groups of parasitic flatworms worldwide with many species described from African freshwater fish. Little is known about the diversity and geographic distribution of monogenean parasites infesting the Red Sea fishes in Egypt. In the present study, a total of 45 specimens of the brushtooth lizardfish Saurida undosquamis (family: Synodontidae) and...

Salmonid cryptobiosis is caused by Cryptobia (Trypanoplasma) salmositica. The haemoflagellate has been reported from all species of Pacific Oncorhynchus spp. on the west coast of North America. It is normally transmitted by the freshwater leech, Piscicola salmositica, in streams and rivers, and sculpins, Cottus spp., are considered important reservoir hosts. The pathogen can also survive on the...

Non-indigenous species that become invasive are one of the main drivers of biodiversity loss worldwide. In various freshwater systems in Europe, populations of native amphipods and fish are progressively displaced by highly adaptive non-indigenous species that can perform explosive range extensions. A total of 40 Ponto-Caspian round gobies Neogobius melanostomus from the Rhine River near Düssel...

The demand for tilapia fishing goods has recently expanded on a national scale. One of the difficulties this fish farming operation encountered was parasite-caused illness. aims study were to explore parasites in (Oreochromis niloticus) from local seller Dramaga, Bogor, West Java. A total 14 sampled, with an average length 22 cm and body weight 195 grams. Fish gills, pectoral fins, caudal tail ...

Published data were used to compare the distance decay of similarity in parasite communities of three marine fish hosts: Atlantic cod Gadus morhua, the dab Limanda limanda and the flounder Platichthys flesus in two adjacent areas that differ with respect to the strength of a salinity gradient. In the Baltic Sea, which exhibits a strong salinity gradient from its connection with the North Sea in...

During a long term of road survey for detection of the zoonotic helminthes in carnivores, a male Vulpes vulpes was naturally found infected by Dioctophyme renale in Caspian Sea littoral in Iran. Since the parasite transmission usually occurs through consumption of fish and other accidental food items, investigation of the worm amongst fish-eating animals in the areas with potential circulation ...

Swimming stamina, measured as time-to-fatigue, was reduced by approximately two-thirds in rainbow trout experimentally infected with Ichthyophonus. Intensity of Ichthyophonus infection was most severe in cardiac muscle but multiple organs were infected to a lesser extent. The mean heart weight of infected fish was 40% greater than that of uninfected fish, the result of parasite biomass, infiltr...
