you're asking for lots of info about sites others may know but decline to provide specific details about those that you know about? not exactly a fair exchange of info is it?
Please let us tell you a story;
There were once two divers who dreamt about finding new reefs and had the drive and finance to do this. They spent a lot of time and money as tourists to find and dive new areas which even the local divers knew nothing about - beautiful coral and (comparatively) very good marine life. Some of these divers were friends and spear fishers (using tanks) - these people promised to respect these places. The divers, foreigners and new in the Philippines, trusted their friends and showed them where the reefs were.
Both areas were totally emptied of marine life within 6 months.
Furthermore, the two divers spent much time researching the control of crown of thorn starfish (some local reefs were infested with these) and they spent much time to research and purchase the best equipment in the World to kill them. (from Australia).
The two divers then left the PI's for 3 months and sold these 'crown of thorn' kits to people who promised to use them. On returning to the PI's, the divers were told that only one dive had been made using the equipment, and witnessed that a whole reef had been totally destroyed by cots which could have been prevented.
Then, despondent - the divers decided to travel along the coast to General Santos for a change of circumstances. There they found pristine reefs and marine life as good/better than anywhere in the World. Not only this, but they met like minded people who knew that that the reefs of the PI's are worth fighting for as they are amongst the wonders of the World. These people (few that they are) demonstrated reef protection/conservation though their actions - not words or promises.
The sites that they they showed us are easily accessible by the same people from Davao who do nothing to care for their reefs there.
To give specific locations of the reefs in the Gensan area on this forum or websites may mean that these reefs will be spearfished and and all our effrots ruined.
Much time, money and effort has already been taken by a few to find, dive and develop these areas including exploration, mapping, buoys, 'making friends' with marine life, etc.
Therefore, we are are very sorry but we will not give specific reef locations here in Mindanao until the mater of reef protection is properly addressed by the Governmenta and real protection is put into place. This is why the Draft EO to protect sharks and rays is so important here.
If we do specifically identify areas, then the good people on this forum will never get the chance to see these places as they should be seen - to see reefs in a pristine state.
We are sure that most people understand this, as this is not about money - it is about protecting the the best coral/marine environment for us, our kids and the World.
Respectfully.
