So I've been a member of a club for years and the fish are now flourishing but a couple of years back there was a KHV outbreak on one of the lakes on the complex which killed a few hundred carp. As part of the management and bio security they banned people using their own nets, slings and mats but they also colour coded nets etc for individual lakes to stop it spreading. Now the fishery manage wants to move all the fish over 20lb from the lake that had KHV into what they decided to be a specimen lake but didnt get the virus. We still have the colour coded nets etc but feel like moving the fish is a much larger risk then fishing tackle.
What are people's thoughts? I think this could be a disaster waiting to happen

I thought carp can still carry khv but not die,if that is the case it could be a complete disaster

Yep. They wouldn't get the stocking permits from the EA based on the KHV risk until extensive testing was carried out.
Sounds proper buzzy but I'd be ringing the EA fisheries team to report the potential movements and ensure it's done properly. Or bring it to the club committee. They may not have even thought about the risk or know enough to realise it is.

Exactly that. Are the club even aware of it? I'd be pointing it out anyway.

Exactly what I was thinking. Spoke to the baliff this morning and his reply was well we know what we are doing. I'm led to believe that they don't need a permit to move them as they on the same complex/water way

They still need a permit to stock the lakes. They may have one and yes it will encompass internal movements within the complex but depending on when they got it, the KHV thing may be listed on there as a condition to the permit.
End of the day, if they do it and it kills off the original stock, the club will be impacted financially as new stock will be hard to source that are KHV carries and members will leave as the fish they want to catch aren't there anymore.
It'd still be worth reporting to the local fisheries team as I believe the FHI (fish health inspectorate) put controls on to stop the spread and wont remove them until they are satisfied KHV isn't present any longer. There will be some legal conditions that stop the movements they are planning.

They clearly don't know what they're doing IMO and the carriers of the KHV might well wipe out the other lakes stock as mentioned. I suppose they may have tested them, or might hold and test, but why do I think not.
A local club to me was notorious for moving fish, once moved gill maggot, was a disaster:-(

Personally, I wouldn't take my gear anywhere near somewhere that had KHV. It just isn't worth the risk for me. Especially this time of year, and with the amount of time I do. You cannot ensure your nets are fully clean, and from what i've read, you may as well piss in the wind than use a dip tank.
Happy to be educated though!

Yea the ones that survive can become carriers and it can lay dormant for years.
2 pools by my house had this happen. A lake that had KHV 10 year previous got re homed into a lake with around 40 fish and some of the best locally or were.
Following year 80% of them were dead. As KHV is impacted more by lake temperature too. Which is its other name Spring Viremia. When water temp is around 16-25 degrees I think it is.
Would be a disaster to move them.

Think people are right saying the virus can lie dormant in fish. Stress is one of the factors for an outbreak. Moving fish will certainly create that.. club will be playing Russian roulette in my eyes

KHV and SVC are different viruses.
Stress and high temps in combination can/will cause dormant diseases of any kind to errupt. High temps are in themselves a form of stress. If I were a betting man I'd put money on a big mortality. Any stocking to established stock is a lottery, if you put a virus into the equation you are asking for trouble.
I was, many years ago, peripherally involved in the production of an EA internal publication on SVC. One of the conclusions was that more work should be carried out into stocking (carp) during cooler periods. For unknown reasons this was kicked out my management. Sigh....

This might help satisfy your mind
It is a pretty **** situation, a water near me got it, decimated the stocks and it does make you wonder when and if it will ever be “safe” again
As for the fishery management, sounds responsible to me supplying the nets etc. I guess they can only follow guidelines on what they can do next.
