I live in Lyon, so was looking at the local news last night..The area to the east and north east of Lyon, has loads of marsh and lake lands... natural spots for migrating birds... it is also one of the largest chicken producing areas of the country 'Poulet de Bresse' is well known here. Hence the precautions, that are for all these public lakes, to protect the millions of chickens.
In most other countries that have been affected, Turkey etc the outbreaks have been pretty localised.
There was a vet on French TV last night who didn't seem to think that this would spread widely in France as the infected birds die very quickly often before they can infect others...
Most carp venues are not on chicken farms either and are private. At the moment they are just telling everyone to confine their poultry inside their coops. The large farms, zoos etc are vaccinating their birds.
It's unlikely they would close down the whole country, unless this things gets widespread, which hasn't happened in other countries with far worse sanitary rules than France.
I think this is one of those media hyped things...
As to a risk to us anglers, well I personally think Weils disease, tetanous, drowning, and Limes disease are far more of a threat...
cheers
