They've been trialled on a couple of places up here and they seem to work.
The EA will come and help install them, they're like floating islands, moored to the lake bed.
It's worked on a bream/silver fish water down the road, along with ropes strung across the water.
Fine for a match lake, not so suitable for bigger/specimen waters, but the club concerned found the cormies soon abandoned the water, so maybe there's something worth looking at here.
This is a King's Lynn AA club water (Shepherd's Port) run in conjunction with the RSPB.
Both parties worked together and the end result is a water with flourishing bird life the average club angler can go and get a good net of roach and bream from.
We have to wake up to the fact a cull isn't acceptable to the wider conservation lobby, let alone the general public and work with these people.
