Sorry-re-sent, as I keep forgetting to remove the C4C logo, which gets an
automated rejection from the list!

Yes, of course Bill,  do no harm!

Yes, do what you can to lower the stress, but if using containers, don't
assume that this is safe- change the water often.  Do not let the mucus and
stress generated chemicals build up, as they will.  And once a coral goes
into toxic shutdown, it seems to spread to the others in the tank- this is
never a problem with deck transport.

Exposure to air is part of the evolutionary heritage of shallow water
corals,which have evolved the ability to survive exposure during spring
tides, even when not sprayed.  Being shoved into a container with unrelated
genotypes and species is not natural, it adds to the stress from what I
have experienced.

But this is a mute point for many of us, as we simply do not have access to
tanks or containers big enough to hold the amount of corals we need
to transport.

People often have a hard time believing that there is no mortality and
stress might be lower for at least some species with deck transport,
assuming that the corals are frequently and copiously sprayed.  We do this
routinely on a weekly basis as we now plant corals onto A-frame structures
with children as part of our present strategies, and then we move the
planted frames out 2-3 km in the boat afterwards, so they are exposed to
the air for 30 minutes or so, sprayed, and with no mortality, with
thousands of branches moved in this way.  However, when moving corals in
tubs, I have had corals stress and corals die (plus back problems
afterwards from lifting water), but this has never happened with air
exposed corals, as the corals do not suffer low oxygenation- the only
danger is drying up which is easily solved by spraying. Of course the deck
surface must be clean and no gasoline or oil present.  You can place them
on a tarp and use that also to shield them from direct sunlight and
wind, but not at the expense of spraying them.  Cloudy days are best, but
rainy days are not good.

In the Solomon islands, we moved entire canoe-loads filled with staghorn
corals, all heaped up, and splashed for over an hour, with no mortality to
the corals. One day someone will set up an experiment and do this for hours
and then perhaps continue for days, to prove that this does not result in
any mortality at all.

When I started doing coral work in the Caribbean in 1993 at UPR, many were
horrified and opposed, how dare I break corals?!!!  How dare I play God?!!
But now many routinely use the methods that I pioneered.  But in this
crisis, the most important thing is to act swiftly, and to use whatever
resources you can find.  So if you are waiting to buy some expensive tanks-
if they are on order and have not arrived, don't wait!  Act now!  The
corals need your help!   Mother nature can intervene as well- She can send
us dark cloudy days, and She can send us a giant fan to cool off the
waters- so if a hurricane pops up, it could be a real blessing that could
help save many corals, especially if it is a near miss storm.

This is a defining moment for coral reefs, and the corals need our help.
We can no longer afford to just sit back and watch on in horror as they
die.  Translocation to cooler reefs has been an option all along for those
reef areas with a strong thermal gradient, but few took this seriously,
thinking that we had much more time.  Even now, everything that we do with
corals assumes that humanity and governments will one day get climate
change under control, so that these lethal temperatures will one day no
longer be the overriding threat.

Regards to all,

Austin
