Hi Spaghetti - yes, it is closer but I had trouble finding a 'France' section (also was thinking about north coast of Spain which doesn't fit into a med type category).
Anyway - not really emigrating but some people I know are so will be going to stay throughout the year - their choice of location not mine so will be trying to do a bit of spearfishing there too - also with global warming it should get warmer sooner
Any chance of Giltheads/Orata in that location ?
Is the fishing mostly over sandy areas ? Any flat fish ?
Like you say I would expect it to be similar to Guernsey but then you have that massive body of water in the gulf and also the Quiberon peninsular so might have some strange microclimates...
Maybe a mix of northern fish (bass / pollack / wrasse / bass / bass / bass) and maybe more southern fish (gilthead / dentex ?) Any chance of dentex ?
Ah well at least the water will be clearer there than here...
