This makes a lot of sense Graham, I’m glad you’ve confirmed it as I often wondered why the random spikes were happening. On my last tench session I had 4 in an hour then not another touch for at least another 3-4 hours. I thought it was something I’d done wrong or perhaps a big pike had been disturbing them. If they are one for doing the rounds and moving on then I guess it makes sense to possibly move when the swim goes dead to get the best sport out of the day??? Nice information cheers.Joe, I think it's more the case that tench groups do circuits of the water.
A couple of places I know you could almost set your watch by them.
Over the last couple of weeks I have had the same as you up to 3 fish then few hours of slow fishing
