Nile tilapia, one of the most popular aquaculture species worldwide, has been introduced into Congo Basin several times for purposes. Previous studies based on morphological features showed that some monogenean gill parasites were co-introduced with tilapia and spilled over to native Congolese cichlids. In this study, we genetically investigated monogeneans from three major parts Basin: Upper, ...

Cophylogenetic studies aim at testing specific hypotheses to understand the nature of coevolving associations between sets of organisms, such as host and parasites. Monogeneans and their hosts provide and interesting platform for these studies due to their high host specificity. In this context, the objective of the present study was to establish whether the relationship between Anacanthorus sp...

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...

Two different batches of meagre Argyrosomus regius were stocked in the same floating cage located in north-eastern Sardinia (western Mediterranean Sea). After 4 mo, the fish started showing non-specific disease signs, such as lethargy, emaciation, gill anaemia and mortality. In total 65 specimens of meagre of both stocks were sampled for parasitological and microbiological analysis, and only 1 ...

The present investigation was carried out to compare the haematological and biochemical parameters in healthy and Monogenean infected Cyprinus carpio. The haematological analysis showed significant reduction (P<0.01) in RBC, haemoglobin, haematocrit (PCV) and lymphocyte in monogenean infected fishes, whereas total leucocyte count (TLC), neutrophils, eosinophils and monocytes significantly incre...

As hosts constitute the resource for parasites, an adaptive radiation in a host can drive one parasite. In Lake Tanganyika, diversification of cichlids has often led to their Cichlidogyrus monogeneans. Hitherto, nshomboi was known only from Boulengerochromis microlepis, sole member Boulengerochromini. Surprisingly, we retrieved this monogenean Perissodus P. straeleni and Haplotaxodon belonging ...

The present study was aimed to investigate parasitic infection of an imported ornamental fish shubunkin, a variety of goldfish, Carassius auratus. The body weight and total length of fish ranged from 1.2-11.8 g and 3.311.6 cm respectively. Thirty fishes were examined, 19 fishes were found infected with one or more species of parasites. The prevalence was 63.33%. Five species of parasites belong...

The Order Monogenea of the Class Trematoda contains (Sproston, 1946) upwards of 679 species, but in only twenty-four of these species has a larval form been described. Of these larvae, fourteen belong to adults that parasitize fresh-water fishes, amphibians or reptiles, and ten to adults that parasitize marine fishes. Udonella caligorum is known (Sproston, 1946) hot to have a larval stage in it...
