Yeah your right it did get bombed there for a while then it stopped until a couple of years ago and some "fishermen " from Lombok came over for another go..my mate Nyoman and the other local fishermen loaded up there jukungs with rocks and went out and stoned them..they haven't ever been back!
Definitely more fishy this year and you are right regarding the moon,tides,currents etc,I try and figure if out but it's pretty hard over there as it can change so quick...I rely heavily on nyomans experience as he has fished these waters for decades.
I dived the island well north of the small rocks and struck the current coming from a totally different direction I'd ever had there and it was strong!..the bait was there and I cautiously dived to 50ft wary of the current and started rapidly drifting along ..I checked my watch and I'd already been pulled down to 75ft,no wonder I had to keep on equalising,this happened quicker than you would believe.I swam with the current and up hit the surface got back in the jukung and went elsewhere....
I think I know where you would of seen all those Mu,that place still can dive real well despite the endless stream of bubble blowers and fishermen though nothing like it must of been in the earlier days when you first started diving there..man that area must of been something else back then!!
Is this the Nyoman you are thinking of Schwaman?
