ABSTRACT Fish are considered one of the important sources protein which invaded by different parasites. This study aimed to shed light on monogenean parasites that infect fish within family Sparidae in Saudi Arabia. A total 30 Argyrops filamentosus specimens were collected from Red Sea, city Jeddah (Saudi Arabia), and then examined for presence Parasitic species isolated studied morphologically...

Trypanosome infections have been reported in several species of fish, in majority of cases described on the basis of morphological characteristics. Trypanosomes in fish are heteroxenous and transmitted by hirudineans. This study aims to evaluate the prevalence and density of infections by Trypanosoma sp. in blood from three species of catfish, Hypostomus regani, H. strigaticeps, H. albopunctatu...

Heavy metal concentrations were determined in 43 perches (Perca fluviatilis) and in two of its most common parasites, the acanthocephalan Acanthocephalus lucii and the cestode Proteocephalus percae, collected in the period 2009-2010 from Ružín, a seriously polluted water reservoir in Slovakia. Samples of muscle, liver, kidney, brain, male and female reproductive organs and adipose tissue of fis...

backgrounds: gyrodactylus is a small monogenean ectoparasite that lives on the skin and fins of most of the world's fish species. gyrodactylus appears to be one of the most prevalent parasites found in ornamental fish, especially in cyprinids. goldfish (carassius auratus) are a popular ornamental fish that are highly contaminated by gyrodcatylus. objectives: the present study is aimed to identi...

OBJECTIVE Some information is available about the parasite fauna and incidence for Clarias gariepinus in Turkey, but digenean parasites have received little attention. The purpose of the study is to contribute to the parasite fauna of Turkey. METHODS From 2007 to 2008, a total 63 Clarias gariepinus that were caught in the Asi River were purchased from the fish market in Hatay and brought on i...

The aim of this study was to detect the occurrence of parasites in Prussian carp, Carassius gibelio as the most important alien fish in Anzali international wetland. This undesirable fish was introduced accidentally to Iran with Chinese carp fries which imported to the country during the last decades and then acceded to Anzali wetland. Today this fish has significant stocks in Anzali wetland bu...

1. The potential for selection against migrants to promote population divergence and speciation is well established in theory, yet there has been relatively little empirical work that has explicitly considered selection against migrants as a form of reproductive barrier, and its importance in the accumulation of reproductive isolation between populations has been overlooked until recently. 2. P...
