Very sad news again...…. Too little is done on many fisheries to prevent the spread of KHV and other diseases/viruses...… I have no doubt that there will be many more cases up and down the country before this season is over... In recent years there have been a lot of outbreaks later in the year, when temperatures are still mild but drying kit out is more difficult...… As an angler, you just have to do what you can to help prevent this sort of thing..... Get stuff dried out properly in the sunlight between trips especially if you fish multiple waters. I bought some steri 7 this year as I have more than one ticket, but even that isn't fail proof, so I've been told...….. I would stay off of any waters that have had outbreaks in the past..... I was gutted to find out that a water I fished in the Spring, had had an outbreak in the not too distant past (I wasn't told until after the event)….. Respooled my reels and got new landing mesh and mat, just in case.... There are some sensible fisheries/ clubs out there that do what they can, and , at least make anglers aware of the risks and consequences, often suppling "on site" nets and mats as a precaution and I guess there are lots that don't. As each year there are more and more cases...… Many believe that channel hopping day ticket anglers fishing waters that aren't well managed are partly to blame, who knows. There are probably a million reasons. All we can do as individuals is do our best to dry our kit out properly and keep our fingers crossed that everyone else does the same...…. Gutted for those waters mentioned in the OP.
