What it is
Chub are river fish that also turn up on some urban canals. They are greedy and shy at the same time. A bit of bread into a hole, a trotted maggot, a legered cheese paste, a worm after rain. Travel light, look, fish the best bit first.
They fight in snags. Hooklength is a compromise between finesse and getting them out. Open season on rivers. A licence, and the sense not to camp on a peg you just spooked.
