BACKGROUND The aim of this study was to detect the occurrence of parasites in fish in Armand River, Chaharmahal va Bakhtyari Province regarding the importance of native fish population in the river. METHODS The occurrence of parasites was investigated in 6 native fish (Capoeta capoeta, C. damascina, C. aculeta, Barbus barbulus, B. grypus and Glyptothorax silviae) collected from the current ma...
Background The increasing demand for raw or undercooked fish products, supplied by both aquaculture and fisheries, raises concerns about the transmission risk to humans of zoonotic parasites. This has led current European Union (EU) Regulation No 1276/2011 amending Annex III (EC) 853/2004 mandating a freezing treatment such products. Zoonotic parasites, particularly anisakid larvae, have been w...
parasitic infection of pampus argenteus was examined from northwest of qeshm island. a total of 62 specimens were caught in summer 2008 and winter 2009 by bottom trawl and the specimens were selected randomly in different length classes and immediately deep frozen. all samples were transferred to laboratory, after measuring fish weight and length, parasitological survey implemented by stereo an...
Empirical studies suggest that most exotic species have fewer parasite species in their introduced range relative to their native range. However, it is less clear how, ecologically, the loss of parasite species translates into a measurable advantage for invaders relative to native species in the new community. We compared parasitism at three levels (species richness, abundance and impact) for a...
This study was carried out to investigate occurrence of parasite in selected cyprinid fish species in Gandoman Lagoon, in the vicinity of Gandoman City, Chaharmahal & Bakhtyari Province. A total of 90 fish specimens including Cyprinus carpio, Carassius auratus gibelio, Capoeta aculeata , C.damascina, Chondrostoma regium and Alburnus alburnus from Gandoman were examined during spring and summer...
Parasites depend on host-derived energy for growth and development, and so are potentially affected by the host's ability to acquire nutrients under competitive foraging scenarios. Although parasites might be expected to grow faster in hosts that are better at acquiring nutrients from natural ecosystems, it is also possible that the most competitive hosts are better at countering infections, if...
