A Koi owner in CT recently had to give up the hobby because otters would kill any Koi he put in his ponds. The following story is about a Koi owner in England who was finally able to defeat the otter the was killing his Koi and goldfish. Certainly straight-sided, deep ponds deter herons, but not otters!
A grandfather who set up a secret camera after dozens of rare fish were stolen from his pond was stunned to discover the thief is likely a hungry otter.
Kelvin Skyrme initially suspected he was being targeted by someone with a grudge against him when he discovered several of his prized Koi carp were missing.
On another occasion the 61-year-old found dozens of his goldfish had been decapitated and left floating in his two ponds.
He set up a secret camera at his home in case the thug returned but was shocked when he captured a wild otter sneaking into his garden and helping itself to his fish.
Mr Skyrme, a craft brewer, estimates the furry thief was responsible for eating hundreds of pounds worth of fish.
He said: "I have been keeping fish for over 40 years and had never seen such devastation.
"Herons will visit garden ponds and eat fish but not to this extent, besides, there are telephone wires over the garden which would deter them plus the fact the ponds are too deep.
"At first I thought someone had it in for me. I didn't have any idea who might do this but you just never know.
"There was only one thing for it, I had to catch them in the act so I bought a night vision, motion sensor camera.
"I was completely taken aback when I saw what had happened.
"I have never seen a wild otter and we are at least a mile from the river and within the city.
"I am an animal lover and in any other circumstances would have loved to have seen a wild otter."
Mr Skyrme, who has two grown-up sons and two granddaughters, has built up a collection of more than 40 fish, including koi, tench, rudd and sturgeon, which he keeps in two large pounds at his home in Hereford.
He added: "I am a bit of a wildlife buff and I would have loved to have seen an otter but this was a case of being unlucky and lucky at the same time.
"My family and I were due to go on holiday so I had to put into effect a quick solution by securely netting the pond, which seems to have done the trick.
"Inspection of the camera on our return showed only a few of the neighbourhood cats and a regularly visiting hedgehog."
