Like Kev was rightly saying you have to check the fence regularly, I mean I'm down there virtually everyday ,those fences especially the ones with electric, or in my case a big solar panel, plus battery ,if the geese hit the wires,causing it to short one dark night its game over..or the local hunt get a whiff of ol foxy 🦊, they damage it as well
It's a constant battle ,I have to be honest ,I've nearly packed it in because of predation ,especially as my mate did . But why should I, angling is what I do ...!!
I lived with it over 30 yrs plus I'm, sadly used to it ,so many venues ruined ..
We fight on ..also ,venues live or die by the attitude of the owner,or anglers, live in denial, bye bye venue...
Famous local saying
No fence ,no fish, no future ..
