When I did my open water diving course, the one lesson that was drummed into me - after I had grasped the rudimentary elements of safety - was the need to preserve the areas where diving takes place and to touch and disturb as little as possible - keeping a safe distance from fragile plants and sea life. It was the same with photography - if you want to photograph wildlife and plants down to a macro level - you have to avoid either disturbing it or standing on it!
Are there any grants or subsidies or tax allowances that could be given as incentives to our numerous but struggling dive centres to work together (which they probably already try to do) to help them to promote themselves and the Marine Reserve more, as a tourist destination - getting articles and ads into international diving magazines, for example, is very very costly for a small diving centre - but done as part a Jávea Promotion pack supported by the Town Hall and all clubbing together, wouldn't cost that much… Not really sure how practical the idea is - just an idle thought in passing - but divers and tourists will keep reserve poachers away - or at least restrict their access - and divers do night dives too - so it could be almost a 24 hour rotation of diving clubs and divers and marine patrols around the reserve during the tourist season!!
