Default Effective depth for electrofishing

Hi all,

Just wondering if anyone knows the effective depth for electrofishing & what the maximum depth that electrofishing can be carried out? Tried google but no joy,

Hoping someone on here has some electrofishing experience - or knows someone who has,

Cheers,

Electric fishing using hand held electrodes is not effective in deep water or wide open waters such as lakes etc.

It is at its most effective in waters up to about a metre deep if wading. It will stun fish at greater depths but lack of visibility makes it very difficult to see them. Fishing deeper water CAN be effective if the fish are being pushed upstream onto shallows where they will break back and it will need some smart nets to catch them.

From a boat on a stillwater it is quite effective if used around weedbeds, bankside vegetation or snags. Out over open water the fish feel the approaching pulses and move away.

Longer fish such as pike are easier to catch than short fish like trout. Small grayling are extremely difficult to catch.

Perhaps you could give a bit more information as to the purpose of your query and the nature of the water you intend using the kit on. Bear in mind the EA will need to give consent for the use of the equipment and may well want to inspect it to ensure it meets their standards.

Thanks Bob - that's really helpful (& as I suspected - shallow water & preferably a narrow stretch required!)

Years ago I witnessed the NRA electrofishing the local parkland duck pond - even though it was only 3ft deep when full they still removed the sleepers that made up the overflow to reduce the level further. In fact it was probably only 1ft deep when they commenced electrofishing.

For info the lake in question is a disused clay tip, over 55ft & In some places 15-18ft under the rod tip! I'm guessing electrofishing isn't even an option on here,

& the reason for enquiring about moving the fish is that its a club water (coarse fish) that we rent on annual basis & otters are seen here regularly - often 3 at a time! At some committee meetings the options have been discussed about how to go about moving the fish to one of our owned (& fenced) waters.

Personally I think the only practical & legal method is to get the fish health checked, sort out a movement licence & rod & line them out,

Some club & committee members are rightly concerned about the otter activity; however no predated carp (or other fish) have been found - I'm actually thinking the depth of the lake could be the fish's friend - for carp it's a couple of flicks of its tail & it could be 30/40ft down & away from an otters paws!

There are many pits in cornwall with that configuration. I fished one for a year, heavily feeding in one spot in the ‘shallows’ for two one month periods and Fishing most days. Could never get the fish to stay in the area. They just seemed nomadic. It was as much a mystery when I left as when I began. Maybe that’s right? Electric Fishing will be just as hopeless. The pits keep their secrets.

Hi Beryl,

Yes - like many deep lakes this water is very mysterious & enigmatic to say the least, there's a few carp that have only been out once or twice in the close on 30 years I have been fishing it! Some have never come out & if it wasn't for the fact I see them occasionally I wouldn't believe it!

Thankfully there's a handful that give themselves up every other year so, so it's not all doom & gloom!

Also the pool goes through years when you don't see many fish & you start to fear the worst - the boom - you get a year when the are very visual in the margins - this year was one of them,
