[Spaniard]

Each province has it's own regulations; if you speak spanish try entering the name of the province you are interested about plus pesca submarina into Google and see what it spits out. I know you at least need a doctors note to say you are fit for the sport but not sure on fees etc. You CANNOT spear at night EVER. Never get caught with scuba and speargun you will get arrested and fined, it happened last week in Ibiza; €60,000 maximum fine. Be wary of any Reserva Marina because you face heavy penalties if caught fishing in one.
