All fishery businesses in France MUST be registered in France, otherwise they are illegal under French law.
All legal fisheries have to list a SIRET number on their website and on any paperwork as proof that they are registered with the French tax authorities. It doesn't matter if the lake owner lives in the UK, or the lake is leased, any income derived from French property MUST be declared in France.
If you have booked a French fishing holiday this year ask the owner for their SIRET number. If they don't have one they are a 'black' fishery which can be raided at any time by the French tax police and shut down. If the owner has a SIRET number you can check it is valid and for a fishing business by typing in the first nine letters on verif.com
If you have booked a black fishery you run the risk of losing your holiday, being thrown off the venue and possibly having your tackle and vehicle confiscated by the police. Personally, if I found I had booked an illegal fishery I would demand my money back and go elsewhere. There really is no excuse for any fishery owner in France, they all know it they must be registered in France and they must be paying taxes in France.
Below is a list of registered English-owned fisheries in France that have a SIRET number, you can book any of these with confidence.
