Prétendre que le Brexit était nécessaire pour sauver la pêche familiale est une fumisterie dès l’origine. Où en sommes-nous ? One year ago Boris Johnson waved a mackerel during a press conference to show his determination to defend the British fishermen. The discussion was basically dishonest: the British fishing rights are allocated by the government to two-thirds (!) of the companies very often foreign, the rest of the companies fighting to have a right on the remaining one-third ! Pretending that the Brexit was necessary to save the family fishing is a real humbug ans sham since the beginning.

Not only that, but British fishermen are unable to sell their catches into the EU because of border delays rendering the fish spoiled.
These things will always be present during major adjustments. There is a modern solution to spoiled fish problem - refrigeration.
