"VanDiesil, Most anglers that fish for carp take much better care of the fish on the bank than most hobbyist fish keepers would ever do with anti-slime removal padded mats, plenty of water to keep the fish moist out of the water as well as antiseptic treatments that are more potent than most of the more expensive ones bought in a pet store (both to treat hook holds as well as scale, fin or body damage).
As an angler and a fish keeper, the welfare of the fish as well as the study of them, is paramount to me, especially when they are out of the water. I have seen fish pictured in hobbyist magazines and books that have been laid in the net straight on top of slabs surrounding the pond!!!!!! That is not good practise at all, nor is placing them on gravel or vegetation. Why is it that mats that anglers use to protect the fish are not widely used by the hobbyist fish keeper when fish are removed for treatment?
I dont know where your getting your information from there my friend but you'll know that under the new animal welfare bill we all have a duty of care to our koi, so I'm supprised you dont mention this besides good practice and duty of care is something weve been practicing for over 27 years now has have everyone I know.
Members of BKKS affiliated sections are taught all about the care of koi when out of the water and laying them on the grass or gravel is not part of those teachings.
We all use extreme care with our koi whe they are out of their enviroment they are placed on baby mats with damp towels atop of that or the more fortununate keepers have a koi cradle for treating their koi .
Never in my 27 years as a Plymouth section member "of which we are the founding fathers to the sectionest 1991" and BKKS member have I seen this practice that you speak of nor are they handled with dry hands.
Infact about the only time a koi's mucus layer is slightly damaged is when a koi is scraped to check for parasites and if found to enable the best in treatments they are then sprayed with propolis and released .
We do not yank them out of their enviroments with hooks after sometimes upwards of an hour struggling on the end of the line becoming stressed to the eyeballs.
Sorry my friend but we rather guide them towards the surface with one of those large flat nets that you must have seen around peoples ponds.
They are then scooped up in a pre wet sock net and placed carefully in a large benching bowl that has been pre treated with anesthesia .
The only time they are handled is when they are placed onto the treatments mat with wet hands, then back in the pond to come around still in the hands until the koi is strong enough to come round and is able to swim free of your hands.
Al koi are QT'd on a routine basis especially because of KHV something which is rife in my carp fishing lakes "yet we koi keepers are often blamed for intoducing it into these lake"which we have not beause we again have a duty by law to report this to DERFA and it is believe the bad practice of moving Carp between countries and lakes is what brought about KHV in Wild Carp and it was tracked back to a specific offender in france , if you read the latest on KHV or the Koi Herpes Virus, then you'll know it is rife throught these lakes in the UK strange isnt it that our ponds remain KHV clear this is because of good Quarentine practice by not only the dealerships and the hobbuist combined .
Where are these culprit koi that have spread the disease through these lakes the truth is they arent there!!!!...........
I wouldnt catch take and put a wild carp in my pond either that way there would be a danger of introducing SVC or Spring Viraemia of Carp which is common to the wild species of carp.
The only time I have ever seen koi laid out on the grass in nets or otherwise on slabs are in books or on sites like the one we are on, only the reason they have been laid out in books or by their owners is because they are already dead and its to take photo's of these koi to use as either teaching aids or to show people like ourselves to see possibly if we can identify what possibly killed them .Perhaps thats what you have seen in the past.
One final word this good practice of handling and treating koi isnt just a UK thing its in AKCA litrature SAKKS litrature and any other country where there are organisations like the BKKS.
Are you a member , if not ty joining us you'll soon learn we all practice good fish husbandry .
