A lethal disease of koi and common carp (species Cyprinus carpio) has afflicted many fish farms worldwide since 1998, causing severe financial losses. Morbidity and mortality are restricted to common carp and koi and appear in spring and autumn, when water temperatures are 18 to 28 degrees C. We have isolated the virus causing the disease from sick fish, propagated it in koi fin cell culture, a...

The recent finding of infectious salmon anemia (ISA) in Eastern North America, first in New Brunswick and more recently in the State of Maine, has been cause for alarm over potential impacts on cultured and wild stocks although there is a lack of scientific information in support of this claim. On the West Coast, scientific evidence indicates that several diseases were affecting wild fish popul...

The recent identification of multiple genotypes of the salmonid parasite Ceratonova shasta with different virulence levels in Chinook Salmon Oncorhynchus tshawytscha suggests that it is possible to immunize fish against subsequent infection and disease. We hypothesized that exposure of Chinook Salmon to the less-virulent parasite genotype (II) prior to the more virulent parasite genotype (I) wo...

in this study, 307 samples of the sediments of fish breeding pools of the different parts of north of iran were tested for the survey of different environmental mycobacteria. after the process of cultivation, 107 cases of mycobacterium were gained which after the performance of different biochemical tests. 112 cases of mycobacterium were identified. from among the isolated mycobacteria, the hig...

Fish farming is an important industry along the Norwegian west coast. This industry provides labor opportunities and financial income in areas that are often thinly populated. Fish are subject to diseases carried by pathogens. The value of the fish that are lost due to disease is worrisome, and emergent diseases continue to pose a severe challenge to the aquaculture industry. We have built an a...

Pansteatitis is caused by the consumption of high levels of unsaturated fatty acids and/or the insufficient intake of vitamin E, leading to inflammation of adipose tissue. This disease has been related to fish-based diets. However, non-conventional diets must also be considered. The authors present case records of two cats with pansteatitis, for which diet consisted mostly of pig's brain, compa...

Background—Onceor twice-weekly consumption of fish (or a small amount of fish intake) reduces the risk of coronary heart disease and sudden cardiac death in Western countries. It is uncertain whether a high frequency or large amount of fish intake, as is the case in Japan, further reduces the risk. Methods and Results—To examine an association between high intake of fish and n3 polyunsaturated ...
