Information sought on reef fish spawning aggregations

NMFS/NOAA has been involved recently in the environmental aspects of a
large road project being built in Palau under treaty between the U.S. and
the Republic of Palau.
Because of some potentially substantial impacts on marine systems (i.e.,
dredging for road aggregate, causeway construction), we have developed a
compensatory mitigation package for the project, including the
establishment of the 30,000 acre Ngaremeduu Conservation Area. One of
the major reasons for designating this particular marine protected area
(including a huge mangrove embayment, lagoon patch reefs, and large
section of barrier reef) off the west coast of Palau, is that it includes
a major grouper spawning channel through the barrier reef.
There are a number of these very important grouper spawning channels in
Palau, particularly in the western barrier reef. I'm somewhat hesitant
to name the ones known to me (for obvious reasons) without the permission
of appropriate people in Palau. Hopefully, via this e-mail to the list,
someone in Palau can respond to you directly with this important
information. Protection of these channels in Palau and elsewhere is
critical. Well enforced MPAs, in my opinion, is the most appropriate
tool for insuring this protection.
