Rod licence fees go towards repairing the environment when something goes wrong e.g. waterways getting polluted and fish stocks being wiped out. People who fish without a rod licence avoid contributing to this fund and leave it to other anglers who do pay for their licence. It’s like car insurance, the fees are higher than they should be to compensate for the dodgers. A rod licence works out at around 50p a week for god’s sake. You know the rules so take the consequences.
