Something is taking bites out of the goldfish
 

Something is taking bites out of the goldfish in the pond. Two have
died and about half of the others have wounds.

We've emptied the pond and repotted all of the plants. We removed all
of the sludge when the pond was empty and sieved it to see if we could
find anything. We've washed and inspected the roots of all of the
floating plants.

We treat the pond with an anti-bacterial treatment and the fish recover
only to be bitten again. I suspected we had a big dragonfly nymph or
something but have been unable to find it.

We have about 15 goldfish from 4 to 8 inches long, one green tench
about 14 inches long and we found two frogs that we moved to the nature
pond down the garden. The pond is netted so that eliminates a Heron
attack but the fish aren't shy as they would be with a predator around.

We found hardly any of the normal bug type creatures we would expect in
a well established pond. This makes me think that something has eaten
all of them and has now started on the fish.

Any suggestions of the next step would be appreciated. We are in North
Yorkshire, UK.

Any chance that something is getting under the edge of the net like a pine
martin or a ferret?

Thanks for the suggestion and yes, something could be getting in down
the streams.

I'd expect these to take the whole fish but they are small bites of
about a centimetre and I'd also expect the fish to be nervous but they
are coming up as usual.

Or Mink? Real problem around here, thanks to the ALF releasing a load
in the 70's.

I would've thought they'd simply make the fish disappear wholesale
rather than in pieces though.

Again there isn't really any damage such as these sort of animals would
cause. I saw a picture of a Dragonfly nymph hanging onto a Stickleback
many years ago and it looks like this. These fish aren't big and my
idea that one is ambushing the fish and hanging on while it chews is
constant with the wounds. The two that died were small fish, one had
it's stomach eaten and the other had it's face eaten and they were
hemispherical wounds. There isn't the normal pondlife we used to have
either. We found one water beetle and three tiny slug like things less
than half a centimetre long. In the past the pond has been teeming with
waterlife and now there just isn't any.

It's possible, but I wouldn't have thought particularly likely. More
some sort of bacterial thing, I'd have thought?

Had a bloody heron at my pond this morning. ++ungood.

We lost two fish this summer they looked like they had been skewered the sad
thing is they lived for a few days with these injuries while we treated
them. We later caught the culprit down at the pond and couldn't believe it
....a magpie!!!
We have had no further incidences but according to our local fish supplier
this is not unusual or unheard of as they are attracted by the shiny
scales....the two we lost were mirror carp with big shiny scales :-(
BTW We live in Scotland
