    Some of Hawaii's coral reefs are not what they used to be due in part to agricultural runoff, silt, and invasive species. But a recent experiment conducted by Biologists produced results that exceeded their expectations. At a test patch in Kaneohe Bay, divers used a vacuum to remove non-native algae and then released 1,200 native collector urchins (Tripneustes gratilla) on half the patch. What they discovered was that very little algae grew back on the urchin side. The non-urchin side grew back thicker than before.

    The biologists are now working on cultivating a large number of urchins at the Anuenue Fisheries Research Center for experiments on other affected areas.

    That was very interesting. Thanks for sharing. k+
    That was one heck of a disease with profound affects - I hope nothing like that occurs out west.
