Ok, I have contacted the guy to offer him my services.
Matts1w : I'm really not sure embargo would be a proper solution, It would just make the fishermen and local communities even more desperate.
Indonesian government is the responsible here as they do not distribute tourism $$$ they get from tourism (including scuba diving) operators.
You just have to get to Nusa Penida from its sister island Nusa Lembongan to see a huge difference between the locals way of life between the 2 islands only separated by a 200 meters wide straigt. Nusa Penida attracts tons of divers and snorkelers every year in search for nice drift dives, Mantas & Mola Mola, meanwhile people from the island got nothing from this ! This is truelly unbelievable !
Obviously tourists that came to Nusa Lembongan don't know about what is happening just 10 kilometers away from their hotels or a few hundreds meter away from the dive spots. This is our little secret here in Nusa Lembongan. I may be the only instructor / guide talking about this every day when giving my briefings : "We don't have much sharks here, you may see a few of them if you're lucky on the north side, but thousands of them are just fished for their fins". Obviously the guests are not happy with this and most of the time can't believe it untill I show them the Bali Advertizer article ...
When I say that not so much has been done in the past 6 months since the article has been released, this is the kind of small talk I have had with the dive operators 10 kilometers away from where the slaughters take place (the same operators that are making $$$ on a daily basis bringing their guests to Nusa Penida) : "it's complicated you know, it's happening between Penida and Lombok, it involves different cultures" or "we have talked about it to the Coral Triangle Center, they are in charge".
So, because this is government and tourists operators little secret, I guess the best way to make a change would be to make this more and more public. When a lot of people will start to complain, may be those guys will start to do something about it instead of waiting and telling that is just a matter of time.
I love this island, I love the way the different dive operators work together but honestly I hate them for just doing nothing about this nightmare.
