More trout disease

Is it the weather? Global warming? Mutated bird 'flu?

The presence of Bacterial Kidney Disease (BKD) has been confirmed in a trout farm in Devon.

Defra has issued an Order under the Diseases of Fish Act 1937, prohibiting all movements of fish to and from the infected Fish Farm and Fishery.

The disease was found in a trout sample during a routine fish health-monitoring visit to the farm. Fish Health Inspectors are currently examining the source of the outbreak and investigations are ongoing. Whilst the disease is considered serious and notifiable under EU law, it is not widespread in Great Britain and occurs only sporadically.

BKD has no implications for human health.

Is this the same as was found at the trout farm in Yorkshire a few weeks ago ??

No. But this has just landed in the email:

"VIRAL HAEMORRHAGIC SEPTICAEMIA UPDATE - VIRUS DETECTED IN GRAYLING SAMPLE



The National Control Centre at the Cefas Weymouth Laboratory has confirmed that viral haemorrhagic septicaemia (VHS) virus had been detected in a sample of grayling taken from the River Nidd below the outlet of the farm infected with the disease. The infected fish showed no clinical signs of the disease.

The discovery was made through comprehensive sampling. Cefas is continuing to test wild fish in the river, both below and above the infected farm to determine the extent of infection.

Although there is no scientific evidence that VHS infection causes significant disease outbreaks in wild freshwater fish stocks, any persisting infection in wild stocks could be a source of infection or re-infection for trout farms in the vicinity through VHS virus contamination of the river supply to the farms.

There have been no further cases of the disease on trout farms in the Ouse/Don catchments of North Yorkshire affected by the current case. The first round of testing on all farmed sites has returned negative results so far and is due to be completed later this week. A second round of testing began last week with results expected by the middle of July.
Results of the further testing will be made known when they have been completed. Fish farmers in the affected area and other stakeholders are being kept informed of the situation."

So now the original one is in the wild population.

does it say which farm mark?

No. That's the full text. I suspect they'll keep it quiet until they have the full SP on what it might have done to the river.

Trout farms do have a lot to answer for - used to pour tons of sh1t into otherwise clean rivers. They have cleaned up their act a bit - and disease can't be blamed on them - but it needed to happen.
