The development and refinement of amphibian medicine comprise an ongoing science that reflects the unique life history of these animals and our growing knowledge of amphibian diseases. Amphibians are notoriously fastidious in terms of captive care requirements, and the majority of diseases of amphibians maintained in captivity will relate directly or indirectly to husbandry and management. Inve...

Abstract The present study investigated the protective effects of dietary Allium cepa against Saprolegnia parasitica infections and amelioration cadmium-induced immunosuppression in Oreochromis niloticus . isolates were recovered during an outbreak saprolegniasis farmed O. raised a poor aquatic environment Isolates identified phenotypically as S. parasitica. Results confirmed further by ITS gen...

Saprolegniasis is one of the most devastating oomycete diseases in freshwater fish which is caused by species in the genus Saprolegnia including Saprolegnia parasitica. In this study, we isolated the strain of S. parasitica from diseased rainbow trout in Korea. Morphological and molecular based identification confirmed that isolated oomycete belongs to the member of S. parasitica, supported by ...

Saprolegnia is one of? the? ?most important agents decreasing the eggs survival rate in sturgeon hatcheries. There are some chemical substances for controlling the fungal infection of eggs. In this study, an attempt was made to introduce a ?germ negative bacterium, Pseudomonas aeroginosa (PTCC1430)(Persian Type Culture Collection) as a biocontrol??ling agent of? ?water mold. Saprolegnia was...

The objective of this study was to determine the effect of different concentrations of anolyte on saprolegniasis in comparison with green malachite in rainbow trout hatcheries, in the northern part of Iran, Tonekabon. Nearly 5000 green eggs of Oncorhynchus mykiss (equivalent to 300 g) were obtained from a private farm in the north of Iran. The study was designed in 5 treatments, 0.25, 0.5, 30 a...

THERMAL HOMEOSTASIS Amphibians are poikilothermic ectotherms. Their core body temperatures are determined by ambient environmental temperatures, and an amphibian thermoregulates by moving through the mosaic of environmental temperatures to find those appropriate for its current physiological needs. The preferred operating temperature zones (POTZ) vary tremendously between species, between geogr...

Haemato-biochemical studies in rainbow trout infected with Saprolegnia were carried out under temperate climatic conditions of Kashmir valley to find out the variation in blood parameters. The trial was carried out on 405 cultured rainbow trout fish ranging in length from 47.8 to 69.8 cm and in weight from 1300 to 1920 g. The same experiment was carried out on 2,70000.00 trout fish eggs from No...
