I have a large pond on my land, about the size of a tennis court normally, but down to about 1/4 of that size at the moment due to the drought, the water that is left is very shallow. I have had a pump going for months now to keep the water oxygenated. Yesterday I used the pump to move some more water into the main part to keep as much water as possible where the fish were. Stupidly I forgot to move the pump back in to where the fish were and this morning there were 6 dead carp. I immediately turned the pump back on and left for work, sadly when I got back this evening almost all the bigger fish were dead.

They're not monsters but I've just put 50 dead carp up to about 15lb into plastic bags for disposal, it looks like a huge oxygen crash overnight, and despite turning the pump back on first thing it was too late to save the fish, only one larger carp is alive although most of the small ones have survived.

Lesson learned sadly, don't assume you can go a single day without oxygenating the water when conditions are as bad as they are at the moment.

Thanks Gerry. Yea I'm gutted really as it was my own fault, that pump had been running 24 hours a day for the last 3 months, I stupidly thought they would be OK for one night. Wrong!

Luckily it wasn't the fish in the pond nearer my house, some of the fish in there are our longest surviving pets including a mirror and grass carp that are both about mid 20's. The mirror and some of the others were actually brought home as fingerlings in a 2 litre ice cream container from a lake I was fishing (with the owners permission) nearly 30 years ago. They started off in a little tank in the front room of our flat and every time we moved they have moved to a bigger pond. Their pond has a filter system and TWO pumps running 24/7 so the water quality is much better and it's easier to keep topped up.

Thanks Tazi, final count was 70 dead carp, 3 of a similar size survived, along with literally hundreds of small carp and goldfish (rescued from a neighbours pond many years ago). All currently in a 12ft x 3ft pool with pump running 24/7.

Some of the littl'uns are beautiful but I can see a restocking happening. I've been looking at VS Fisheries website!

what a sad loss, just goes to show what a fine balance your pond must have been on.

Viv's a top bloke, you wont go far wrong with him or his fish.

Dave at Front fish are also exceptional

Ive bought carp from both of them

It's not a nice experience when you see all those years of nurturing from fry all gone in an few hours, from what you have posted it sounds like the stock was relying on the pump?

If you was going to re-stock I'd be thinking about lower numbers a tad (Size dependant) so you only need the Pump for emergencies, just a thought

Heart breaking mate - I know how it feels...
Keep an eye on the fish in the new pond - they have a habit of jumping out when moved.

I dug the pond 18 years ago. The original stocking was 15 small carp, 15 small rudd and I later added a few perch. A few years after that I agreed to rescue the fish from a neighbours pond, 'if you don't take them they'll all die as we have to fill the pond in!' That was about 200 small carp and goldfish, which I wasn't happy about but wasn't going to kill them.

Over the years they obviously bred and grew, sadly none of the rudd or perch were there at the end.

It had developed a leak when over 1/2 full so I just let it evaporate during the last 3 months until we could get a digger in and try to sort out the leak, this is when the fish were left in a much smaller volume of water and that was my downfall.

I certainly won't overstock and will try to add a few predators if I can but perch don't seem to do well and I doubt pike would do any better. A couple of small cats would be ideal, but I think that's illegal!

Plenty of time to think about restocking, it's unlikely to be full again until the winter, assuming we get some rain at some point!

Yup we've had that and also the heron finding them and perching on the side of the pool to help himself. I've now put netting over it to prevent both those problems.

If youre not on a water course, and smaller than a certain size, i beelvie 1/2 acre - you would be ok with cats - However,

Only stock 1 if you dont want them to breed, or purchase ones at a size easy enough to sex.

You've had a proper run of bad luck Paul, as for Cats – Register the water with the EA, add Catfish along with all the “Standard” species to the list you would like to stock. If the water meets the criteria, Not In-line, not on a Flood Plain and fully secure (Thinks it means as in, nobody can just walk on and fish it /remove stock) you stand a chance.

your lake will have to be classed as "Land locked" to stock cats.

personally i wouldnt stock them, just run a net through every yr to thin stock down

Not In-Line - same thing as Landlocked Joss. But even most Landlocked waters always have an over-flow, in which case they will stipulate that you fit a "Bio-Filter". Basically a enclosure with a stainless Steel Mesh base built in , so no Catfish fry could ever get washed out into the main water courses.

Think I would try Pike first, before going down the Catfish route.

yeah mate, thought so.

I cant stand catfish in waters, dont think they have a place, but thats my opinion.

Pike, perch and a few brown trout

"Brown Trout" that's an interesting one. Was always lead to believe they don't do well in Carp waters, gravel pit type venues anyway.
Fished a carp water many moons ago where they were put in, didn't do well at all.

Yes;but what I was trying to say is brown trout require a much higher oxygen level to thrive than carp. Carp are amongst the hardiest of fish.

Only trouble with Trout is if your water has high quality gin clear water, they become a Cormorant magnet during winter months. And you end up with a few Carp getting “Spiked” by the dammed things – not a pretty sight if the wound gets infected, as they rot from the inside out.

I do have a few Rainbows and Brownies in one lake but they are between 16-20lb in size, they have thrived alongside the Carp, Cats, Pike, Roach, Perch and Grass Carp.

Brownies do look impressive (Off memory, as they never get caught!) they looked more like Salmon with the Hooked Jaw.

You do see them thou hurtling up the lake like a torpedo.

Nope, I've often thought about having a go for them - but via Fly it's impossible with all the purposely planted bankside Trees & Bushes, wading out is out of the question with the sloping margins, On the worm - everything else would be after them too, same on a Lure/Spinner the Perch and Pike would be.

Talking of trout, many years ago we stocked with a few hundred 8-10" rainbows as a fry predator, a couple of years later I was catching 5lbers on the drop on 20mm boilies

I used to fish a lake that was fed by a small river that had Gudgeon in. Sadly they are long gone. Got to go to the Thames fo Gudgeon now.. Great fun but not many people bother as they are so small. I've had a few from the Thames many years ago near record size.

The water quality isn't great unfortunately, it was dug about 20 years ago and is clay lined, so with carp in it it is very much a mud puddle., certainly during the warmer months.

I'm sure I put perch in before but none of them survived. In fact I put roach and rudd in and none of those survived either. We do have daily visits from at least one heron so I suspect he got quite a few of them.

I am willing to try other species especially predators, does anyone have any recommendations for suppliers of perch, pike or trout?

Very sorry to read this

Just thinking aloud, wont help with immediate results but regards restocking would there be any merit in breeding from those that survived. It might be just luck they survived, conversely it may be a trait they have that enable them to do so, all fish are not the same as we know from selective breeding.

The small fish that survived are certainly going back into the pond, my other half wouldn't have it any other way, which is a bit annoying as I wasn't a fan of putting a mixture of goldfish, ghosties and small carp from someone else's garden pond in there in the first place! I think they survived because they were much smaller rather than any inherent hardiness.

Thanks Andy, I'm in Battle, near Hastings on the south coast so quite a way from Essex, but of you're ever passing........

p.s. I may even take one or two bream, they'll never be fished for and they do get a lot of hate from us carp anglers, when I was about eight my PB was a 3lb 2oz bream, I was so chuffed with that 'biggy'!
