My favourite is rule number 4 - I have heard that this is an issue that has caused some frictions between fishermen and divers lately. Personally, despite my strong views about conservation I am not a big fun of activist style action. I do believe that conservation is about education and awareness - like everything it requires a sustainable plan and suitable alternatives for people who make their living out of the sea - but that's another (long) story. However, apart from the fact that I fail to understand the role of cages and fishing nets in a marine reserve (other than maybe the fact that fishing is allowed on a seasonal basis?) I cannot remove from my head this image of divers/snorkelers suddenly disintegrating with fishing equipment.
In my imaginary world I have created a wicked version of battleship: I am placing diver in cell A4; diver activates self-destruct button on BCD while touching net - boom - net and diver disintegrated. Fish wins!
Ah... how boring would the world be if things didn't get lost in translation
