Southeast Coastal Ocean Regional "News"
This section is intended to provide brief reports on SE Coastal Ocean programs and
events that were not included in the main body of the Southeast Coastal Ocean Report.
The following item from the Florida Keys Marine Sanctuary provides an example of
what is intended to be an expanded "news" section in future reports.
Some Coral Reef News

In the summer of 2004, a team of researchers led by Jerry Ault (Rosenstiel School of
Marine and Atmospheric Science, University of Miami) surveyed reef fish populations in
an area covering nearly 450 square nautical miles in the Tortugas Ecological Reserve-
North (Florida Keys National Marine Sanctuary), the adjacent section of the Tortugas
Bank that remains open to commercial and recreational fishing, and in Dry Tortugas
National Park, where commercial fishing has been banned since 1960. The Tortugas
Ecological Reserve, which covers over 150 square nautical miles, is the largest no-take
marine zone in U.S. waters. In addition to RSMAS/UM, the team included scientists from
NOAA/NMFS, National Park Service, Florida Fish and Wildlife Conservation
Commission, and the UNC-Wilmington/National Undersea Research Center. They
mapped nine types of benthic habitats and recorded the abundance and size of nearly 300
fish species.
Results of the survey showed that pinnacle and reef terrace habitats had the highest
diversity of fish species and that the Tortugas reserve and park had higher fish diversities
than the fished section of the Tortugas Bank. The survey recorded greater abundances of
red and black grouper than had been counted in 1999 and 2000, prior to implementation
of the ecological reserve in 2001; black grouper abundance had increased four-to-five-
fold over previous surveys in the same areas. The marine protected areas should not get
sole credit for this upsurge in black grouper populations since there was also an increase
in the legal-catch size in 1999. Ault concluded that the system is moving in the right
direction, given these increases in diversity and abundance of reef fishes. Increases in
heavily exploited reef fishes and spiny lobster have also been measured in the rest of the
network of fully protected marine zones in the Florida Keys National Marine Sanctuary,
implemented in 1997.
