Europeans take their fishing seriously as demonstrated by the latest conflict between the UK and France. Here is one of many reports on the subject.
The question revolves around the Brits agreeing to license a number of French fishing vessels, but requiring proof that they had fished in British waters prior to Brexit.
If it were I, I would say, you French can decide which boats should get the limited number of licenses, that would make it an internal French conflict rather than UK vs France (and EU).
