Fensmere Fish Farm

A little update from Fensmere Fish Farm

With the increasingly hot and dry summers we’ve been experiencing here in France, I’ve had more and more conversations with lake owners about dissolved oxygen, aeration and how best to protect fish stocks during extreme conditions.

After working with Mark Stockton at Aqua Culture Equipment, Simon Littmoden at ZooAqua and Pramac, I’m now able to supply a range of Aqua & Co surface aeration systems, ZooAqua diffused-air systems and Pramac generators here in France.

The important thing for me isn’t simply selling equipment. Every lake is different, and there isn’t a single aeration system that is right for every situation. Lake depth, size, shape, fish biomass, stocking levels, power availability and how the equipment is going to be used all need to be considered.

One of the advantages of having Fensmere Fish Farm involved is that I will be holding stock here in France, based about an hour from Limoges. This means that, wherever possible, equipment can be supplied quickly rather than having to wait for everything to come from Italy or the UK.

If I don’t have the particular unit you need in stock, current lead times are generally around 8–10 days, and equipment can be delivered directly to the lake owner’s property.

The range includes:

• Aqua & Co surface and splash aerators
• Brio and directional aeration systems
• Force 7 Venturi aerators
• Rio water movers for high-volume circulation and destratification
• ZooAqua diffused-air systems for deeper lakes
• Pramac generators with Honda engines
• Advice on putting different systems together depending on the lake

I’m particularly keen to help lake owners who aren’t sure what type of aeration they actually need, rather than simply recommending equipment.

If you’re managing a lake in France and want to have a chat about oxygen levels, aeration, circulation, emergency backup or planning ahead for the increasingly difficult summer conditions, feel free to contact me.

I’ll do my very best to help, even if that simply means pointing you in the right direction.

Hopefully having equipment and knowledge available here in France will make things a little easier for lake owners when it comes to protecting their fish.

I love hearing feedback from lake owners who we have delivered fish to about how well they are doing. This fish was delivered up to St Malo to Kenny Dezitter’s lake and obviously spent last summer doing rather well. Nearly gaining 10lb in one summer and looking set to become a huge fish of the future. Kenny also said many other fish look even bigger as well from the fish we supplied showing the true potential of this strain of incredible Carp 😍😍😍

🎬 FENSMERE HARVEST 2025 – A Fish Farmer’s Story

For the last three winters, we’ve been quietly filming something different at Fensmere.

This isn’t a highlight reel or a fly-on-the-wall video.
It’s a documentary that looks at the annual harvest — the netting, the grading, the deliveries — but also at the friendships, responsibility and trust that sit behind it all.

Filmed over three years with an experienced documentary filmmaker whose work includes BBC, ITV and Channel 4, this film offers a rare look behind the scenes of fish farming and fishery life.

The full documentary will be released on Christmas Eve 2025.

We’ve shared a short trailer below.
If it speaks to you, we’d appreciate you following along and sharing it with anyone who understands what this life is really about.

Over the next couple of weeks I will be draining and grading my C1 pond and holding tank at the farm. I have already done a rough grading of these fish, but have waited until the Cormorant issues are nearly done to do the final grading and put them out into the top lake for the summer.
I will have several thousand incredible C1’s available here at the farm for sale. These fish will reach between 2-4kgs by December of this year and be fully predator proof if fed correctly through this coming growing season.
For any fisheries here in France that have a small stock pond they represent a great way to grow on your future stock.
I will be selling these fish in batches of 3-400 fish at between €3- 400/batch depending upon size and scale patterns.
If you are interested drop me a PM or email. I will not deliver these smaller fish, so a small aerated tank would be needed to transfer.

After a super tough week with flooding up at the fish farm. Then snow as I was trying to get the siphons set up to drain the top lake, I was due a break. I decided to throw the fishing gear in the truck and head off to a 1000 acre Barrage I fish about an hour away. What a session it turned out to be. Just a short 7 hours and 5 cracking carp landed and all wild probably uncaught belters 👌 Sometimes things just come together eh, I documented the session for The Fensmere Carpy Chronicles over in our YouTube channel.
