Hawaii: Coral Disease Outbreak Spreading At Alarming Rate

HONOLULU -- Colonies of rice coral in Kanehoe Bay are being killed
by a disease scientists believe could do serious damage to
Hawaii’s reef ecosystem. Three emergency response teams are tasked
with trying to assess the extent of the die-off. A diver armed
with a GPS device is helping to log and track the spread of the
disease. About a year ago scientists saw a milder outbreak, but
they are alarmed at the rate that the coral heads are now dying.
"This tissues sluffs off this coral within one or two weeks. They
are killing these huge colonies," said Greta Aeby, of the Hawaii
Institute of Marine Biology.
Those colonies are 10-20 years old and so it could take decades to
replace them. The south end of the bay is where most of the damage
is occurring. Scientists are finding it all along the fringing
reefs and other areas further out in the bay.
"We have manipulative studies to try and figure out what are the
enviromental stressors. We've got pretty good evidence that it is
a bacterial infection. We are working with microbiologists at the
University of Hawaii who are studying this,” Aeby said.
You can sense the urgency in Aeby's voice, as she tries to explain
why the community should care.
"It's the reefs that support the entire eco-system. With out the
corals for the crabs and shrimp to live in, there is no food for
the little fish, so the whole eco-system will start collapsing.
This is what's happening in the other areas in the Carribean. The
fisheries are collapsing the reefs are collapsing. It is not a
good thing," said Aeby.
She is asking for the public’s help to be a part of the "Eyes Of
the Reef" reporting network.
"This is a program where we train anybody who is out on the water,
fishermen, paddle boarders swimmers. It doesn’t matter if you are
out on the reef looking at the coral you will be able to recognize
change," Aeby said.
The free training program is offered on the Big Island, Maui,
Kauai and Oahu. For information, log onto the websites of “Eyes of
the Reef” or “Reef Check.”
