Condition factor of fish species is very important parameter for understanding fish biology and pathology. For that purpose, we sampled 120 fish individuals from the Sava River at four locations (Posavina region), where most of them belongs to the Cyprinidae family while the others belonging to the families: Percidae, Siluridae, Ameiuridae, Esocidae and Gobiidae. In total fish sample we found t...

a total of 128 spiny eels mastacembelus mastacembelus (mastacembelidae) were collected from thegreater zab river at iski kalak town, west of erbil city, kurdistan region, iraq, from july 2007 to the end ofjune 2008. the fish were examined for ecto and endo parasites. the study revealed the existence of 16species of parasites (with a total prevalence of 89.06%) including: two species of protozoa...

Histopathology provides a rapid method to detect effects of irritants and pathogens in different organs and it can be considered as the indicator for abnormal condition for fish environment. The present study was initiated to record the histopathological lesions of gill and skin associated with external parasites in two common aquarium fish, Oscar (Astronotus ocellatus) and Discus (Symphysodon ...

The parasite fauna of 50 specimens of spiny eel obtained from two lakes, Zarivar (in Kurdistan province) and Parishan (in Fars province) and one river, Heleh (Booshehr province) were examined during the year 2003. A total of nine parasite species were found. Gills of spiny eel were infected with Ichthyophthirius multifiliis , Trichodina pediculus (protozoa) and Mastacembelocleidus heteranchorus...

The study included 144 fishes in Lake of 16 Tishreen Dam for detecting the infection with parasitic Protozoans, and determine distribution rate. Fishes were collected randomly once a month, during period from 22/12/2011 until 22/12/2012. Collected samples belonged to following species: Cyprinus carpio L., Varicorhinus damascinus, Garra rufa, Tilapia zillii, Liza abu. T. zillii was most prevalen...

Specimens of Solea aegyptiaca caught from Ghar El Melh lagoon in Tunisia were investigated for trichodinid ectoparasites. One species of the genus Trichodina was recorded on the gills of S. aegyptiaca. This species is identified as Trichodina gobii Raabe, 1959 which is reported for the first time on the soleidae fishes from Tunisian waters. The prevalence and the mean intensity level of these c...
