An acute mortality caused by an uncertain agent occurred in wild golden grey mullet (Liza auratus) population in the Iranian side of the Caspian Sea in February, 2004. Clinical signs of the moribund fish were erratic behavior such as spiral swimming, belly-up at rest and over inflation of swim bladder. Histological examination of brain of dead fish revealed hyperaemia, degeneration and necrosis...

In the present study, the effects of Chlorella vulgaris on blood and immunological parameters of Caspian salmon (Salmo trutta caspius) before and after exposure to Viral Nervous Necrosis (VNN) virus were examined. In this regard, four treatments in triplicate were chosen. Groups included one control and 3treatments (T1, T2 and T3). Fish in control group, T1, T2 and T3 were fed diets supplement...
concentration of as in the muscle and liver of aspius vorax, cyprinion macrostomus, barbus luteus in karoon river and liza klunzingeri and liza macrolepis from hendijan port, persian gulf, were investigated in 2011. in this study, 30 samples of fish were collected in winter. metals were extracted from the tissues using wet the digestion method and concentration of the heavy metals were measured...
Three fish species (Cyprinus carpio, Ctenopharyngodon idella and Carrassius auratus auratus) were artificially infected with the fungus Saprolegnia parasitica. The infection was done under certain laboratory circumstances represented by a change in temperature (10, 15, 20, 25 30°C) nutrients (normal, decrease increase nutrients) constant pH. statistical analysis of results showed that influence...
Plesiadapids are extinct relatives of extant euarchontans (primates, dermopterans, and scandentians), which lived in North America and Europe during the Paleocene and Early Eocene. The only genus of plesiadapid whose species are absent from Paleocene strata is Platychoerops. Further, Platychoerops is the only group found in sediments post-dating the Paleocene-Eocene boundary (PEB) by a substant...
A tetraploidization event took place in the cyprinid lineage leading to goldfishes about 15 million years ago. A PCR survey for Hox genes in the goldfish Carassius auratus auratus (Actinopterygii: Cyprinidae) was performed to assess the consequences of this genome duplication. Not surprisingly, the genomic organization of the Hox gene clusters of goldfish is similar to that of the closely relat...
