I’ve found fishing after sunset to be much better for chub, especially if the water is very clear, and the secret to catching chub after dark or in coloured water is to use a stinky bait like cheesepaste.
How to make cheese paste…
I don’t feed much, maybe a few lumps here and there.
If there’s a chub in your swim he will be on the paste in a flash, so if I don’t get any action within 25 to 30 minutes, it’s time to up sticks and move to another swim!
Cover as much water as possible and if your stretch has a good number of chub, you can be certain of a few bites. So, don’t fear the dark, the chub will still feed, you just need something they can sniff out!
