Dear Coral list members,

Last week I was diving at the southern Gulf of Aqaba at the Tomas and
Jackson reefs. I was very surprise to observed that the reefs where eaten
by the Crown of Thorns starfish. I counted 25 starfish in 2 dives of 45 min
each, at noon time (the starfish is active in night time). Usually its very
rare to meet this starfish in the Gulf of Aqaba so i think that we
experiencing a over explosion of this Crown of Thorns in our area.
It haven't reached Eilat yet but it may do so soon. Is anyone have
experience in controlling such a phenomenon? Are there any action needed to
be done before its will reach our area.

Thanks David.
