Viral hemorrhagic septicemia virus (VHSV) is a seriously problematic pathogen in olive flounder (Paralichthys olivaceus) aquaculture farms in South Korea. Here, we report the complete genome sequence of VHSV which was isolated from spleen and kidney tissues of dead fish at an aquaculture farm in 2005. This genome sequence will be useful for virus diagnostics and in comparative analyses with oth...

Autoimmune gonad destruction was induced in Atlantic salmon of both sexes in trials carried out on fish kept in sea cages on a fish farm. Damage to gonads was only found in fish where the first injection of gonad extract had been given together with Complete Freund's Adjuvant, injections without adjuvant or with carrageenan as an adjuvant were unsuccessful. Length and weight differences between...

The enhanced expression of heat shock proteins (hsps) in organisms can be detected in response to many kinds of stressor. For fish, high temperature is an important stressor, and hsp expression is associated with differences in environmental temperature. In this study, rainbow trout (Oncorhynchus mykiss) that were accustomed to an aquatic temperature of 18°C were exposed to an elevated temperat...

This study assessed the technical efficiency of fish farmers in Ibadan metropolis of Oyo State, Nigeria using the stochastic frontier production function analysis. Primary data were collected from 82 fish farmers in Ibadan metropolis. The mean efficiency value was 0.906 with majority (65.9 percent) of the fish farmers being over 90 percent efficient and about 34.1 percent having technical effic...

OBJECTIVE To investigate a case of mass mortality of Garra rufa (G. rufa) from a fish hatchery farm in Slovakia. METHODS Causative bacterial agent was swabbing out of affected fish skin area and subsequently identified using commercial test system. Antibiotic susceptibility was determined by the disk diffusion method. RESULTS Infected G. rufa was characterized by abnormal swimming behaviour...

A batch of experimental rainbow trout was found to have a high level of spinal deformities. An equal deformity level was found in fish from the same batch, but reared at the fish farm from where the fry originated, suggesting that the all-female triploid status of the rainbow trout might account for the high level of deformity. Many factors being of physical, chemical, environmental or genetic ...

Commercial farming of Atlantic salmon in Scotland started in 1969 and has since expanded to produce >179,000 t yr. A government department has published annual statistics and information on the seawater and freshwater sub-sectors of the Scottish salmon farming industry since 1979, and this review collates and discusses metrics covering aspects of production, farm sites and systems, fish perform...
