We have a very large pond here - mini lakish and a year or so ago we think an Otter wiped out our entire fish stock over one winter.
Least it's the only think we can think of.
We had loads of Koi, Shubunkin and goldfish and some of the Koi were a few years old so decent sizes. They went under the plants for the winter and only one original Koi survived by the spring.
We have the ideal territory here for them with a burn running through the land also and a mini wooded area but I haven't seen one as yet. (though I did see a dead one just up the road, poor thing. It was bloomin huge too)
Really hope we do have one or two setting up home here, it would be great to see.
Life isn't about waiting for the storm to pass, it's about learning to dance in the rain.
