New Caledonia Expedition: An Army of Giant Parrotfish

Today we dove at Astrolabe Reef, a remote coral atoll northeast of New Caledonia. So far it’s the best place we have explored.

In our dives today we’ve seen everything one hopes to see: sharks, groupers, Napoleon wrasse, bright red old sea fans, and many other gorgeous animals. But the most impressive sight – and one that we will remember for a long time – was a school of 75 bumphead parrotfish (Bolbometopon muricatum). They are the largest of the parrotfishes, with a maximum length of 130cm and can weigh up to 50kg! The bumphead parrotfish is a vulnerable species, and a great indicator of fishing pressure: they are one of the few species to go away when people start fishing a reef.

This is why we are so excited and happy today, because we know that Astrolabe is still a pristine reef full of large animals. This is the most precious jewel we have explored in the last three weeks.

    Wake up you humans, mine and your trouble is that there is TOO MANY OF US and WE SHOULD BE CULLED! Bad persons get locked up and we continue to feed and care for them! In China they shoot about 100 criminals each week which is a drop in a swelling ocean of two legged ‘ants’! A talk just given in America, suggests we should be consuming ‘plant protein’?

    Places like these should be kept a secret otherwise it will be fished out in a year. Now we know where to catch the big fish, also the parrot fish is responsible for killing the reefs by eating it producing sand.

    I’ve seen large schools of Bumphead Parrotfish. They really are so cool. If they were human, they’d be riding Italian scooters and saying “Ciao”

    Good afternoon Mr. Sala,

    Is the bumphead parrotfish aggressive to other fishes?
    Also, have you seen a decline in reefs in the Astrolabe
    over the years or has it been growing consistently?

    Thank you,
    Kaushal S. Pandya

    ” This is why we are so excited and happy today, because we know that Astrolabe is still a pristine reef full of large animals. ”

    NOW THAT THE WHOLE WORLD KNOWS THAT, THE FISHMONGERS WILL HURRY UP TO FISH IT TO DEAD. THANK YOU NATIONAL GEOGRAPHIC……
