Parasitic diseases are harmful and limiting factors in breeding and rearing ornamental fish industry. In this study, 400 apparently healthy ornamental fishes from five species (each species 80 specimens) including: Goldfish (Carassius auratus), guppy (Poecilia reticulate), angelfish (Pterophyllum scalare), discus (Symphsodon discus) and sailfin molli...

background: in anzali lagoon, there are some endemic and exotic fishes. the present study was conducted to compare the parasitic fauna of blicca bjeorkna , as an endemic fish and hemicul­ter leucisculus , as an introduced fish to the lagoon. methods: a parasitological investigation was done on 78 specimens of b. bjoerkna and 114 of h. leu­cisculus . the fishes were collected from august 2009 to...

The present study reports on the main parasites found in mullet (Mugil platanus) and their prevalence throughout the year on Uruguayan coasts of the River Plate. The following parasites were found: Ichthyobodo necator, Trichodina sp., Scyphidia sp, Gyrodactylus sp., Dactylogyrus sp., Metamicrocotyla sp., Dicrogaster sp., Phagicola sp. and “Scolex polymorphus”. The viability of mullet (Mugil pla...

A total of 140 Fundulus seminolis were collected from Lake George (29° 17' 12” N 81° 35' 53” W) in Volusia County Florida, USA on three separate occasions from March through May 2007. Fish were transported back to a laboratory for biopsies of intestine, skin, fin, and gills. Biopsies were analyzed and parasites were identified and enumerated. Thirteen distinct taxa were identified as parasites ...

Present theory states that in species-poor assemblages interactions among species are negligible and assemblage structure is a result of host/parasite interactions. A corollary to this theory is that parasite species assemblages should behave as accumulations of multiple-kind items drawn from a population in which only the relative probability of drawing each kind varies. This study was designe...

In a study of the parasite fauna of the European eel (Anguilla anguilla L.) in northwest Spain, we found frequent mixed infection of branchial tissues by the myxosporidian Myxidium giardi (prevalence 95%) and by two monogeneans (Pseudodactylogyrus anguillae and P. bini; joint prevalence 56%). All three species are common parasites in this host. In one of the 323 eels examined, hyperparasitism o...
