It's actually quite scary just how fast something that seems perfectly sound can turn out to be an ecological disaster.

A couple way up the valley near the headwaters of the major feeder burn to the Clyde had a duck pond....and they brought in signal crayfish to feed the ducks.
Thing is though, signal crayfish will happily escape a pond and go walkabout to find other waters...and these ones did so.
They are now rife in every burn and river that feeds the major river that drains half the Scottish lowlands.
All because folks thought that the wee crayfish would feed their ducks.

The signal crayfish have pretty much wiped out the native ones, and they predate every other water living species in their endless hunger.

Repeat that across the country and it's all too easy to see how invasive species cause grief.

Exactly, people put so little thought into the long term consequences of their actions.

We have an issue on one of our local rivers that has Wels Catfish in it, they don't occur naturally and have either come from a fishery close to the headwaters of the river that has them and they have escaped during winter floods or its eejits having them in their garden pond not realising how big they get and rather than get rid of them properly, they just dumped them in the river without thinking about the devastating effect they can have on the indigenous fish/wildlife population of the river.

If anyone catches one they cannot by law return it to the river, they have to retain it and call the Environment Agency who will come and collect it and rehome it with a specialist fish farm or collector or they can euthanise it.

Total recipe for disaster and subject to either heavy fines or time at Her Majesty's pleasure for the most serious offences.
Do the EA actually do much down your way? Down here they don't seem to bother prosecuting much.

I've considered digging and stocking a pond and the stream it would be close to once had trout. However, the farm run off in this area has long since killed the vast majority of the fish and the EA don't seem that bothered. However, I expect I would have to follow the all sorts or regs even if most don't.

The EA round here are really good, very active and very good at keeping controlling clubs/landowners etc informed of what's been going on, they are also very receptive to reports from the public, clubs etc about illegal fishing/activity and act upon it.

I see from your profile you are in Devon, i know of one fishery down your way that was prosecuted and fined to the tune of £40k for stocking illegal species into one of their ponds, was a massive operation to eradicate them and i doubt the fine even partially covered the cost of the clean up operation by the EA.

But still subject to the laws of the land which specifically prohibit the stocking of any water with fish or other aquatic species without the necessary movement permits, stocking license, health checks, eco impact surveys and assessments, invertebrate surveys etc etc etc.

I have the necessary licence from CEFIS. The pond has a small rivulet running into it from a spring higher up (all my springs are on the higher ground, weirdly) and the overflow is a small weir into a 300mm pipe that flows into a ditch. In warmer weather (remember that?) it doesn't reach the overflow. In wet weather, like now, the depth of the overflow is a few mm and obscured by bullrush, so for a fish to jump it they'd have to be psychic. The pipe actually slopes upwards at the far end so the outflow from that is a mere dribble.

It's a good discussion. I do fancy having some trout for the grill but if they have to be triploid then it's an expensive way of providing them

Our lochans often have wee brown trout in them.
They're never very big trout, but the folks who fish and eat them find them tasty enough.

Since those are native trout, would they be allowed to be stocked in your pond ?

All stocked trout have to be triploid, brown or rainbow, as far as I can tell.

CEFAS (Centre for Environment Fisheries & Aquaculture Science) don't issue licences to stock fish they are the statutory body under which "Aquaculture Holdings" ie fisheries must be registered.

You are quite right, CEFAS is the body that I'm registered with. I'm aware that movements must be registered.

I have a fairly large pond (1/2 acre) which we use for swimming and wildlife. I'd like to be able to eat fish (trout) from it but I've heard that they're not good for other wildlife, presumably because they predate on insects, tadpoles etc.

We have a heron visiting quite often but the pond is very deep in places so hoping the fish will be able to escape into the depths, or is this wishful thinking?
coarse fish can be tasty if you put them in a hot curry otherwise they taste like compost
