Proceedings of the Symposium on Corals and Coral Reefs, 1969
The First International Coral Reef Symposium was held at the Central Marine Fisheries Research Institute, Mandapam Camp, India from 12-16th January 1969. Scientists from 11 countries attended and discussed diverse issues related to coral reef studies.
Based on the success of the Mandapam Camp symposium, it was decided that such meetings should be held at intervals of three years at main centers of reef studies and a preliminary organizational framework for conducting similar symposia on corals reefs was laid out at the end of this symposium.

Abstract
|
Sekisei reef is a rare example of a barrier
reef that is developed on tectonically active margin
between the islands of Ishigaki and Iriomote in the
southern Ryukyu Islands, Japan. Cores from three
drill holes and five seismic profiles provide data for
discussion of post-glacial barrier reef formation. The
Holocene sequence of Sekisei Reef is less than 20 m
thick and established on an extensive antecedent
platform around -20 m which is considered to be a
major factor controlling the formation of the barrier
reef. Age data indicate that the Holocene reef started
to grow around 8,500 cal. yr BP with simultaneous
growth on both the rim and in the lagoon. The
lagoonal patch reef, composed of branching
acroporid corals and calcareous algae, grew rapidly at
an average rate of 9.2 m/ka, reaching sea level at
6,500 cal. yr BP. In contrast, the barrier reef rim,
composed of tabular acroporids, apparently grew to
sea level at around 4,000 cal. yr BP, giving a lag of
2,500 years. Vigorous growth of back reef zones in
the early stages of high-latitude barrier-reef
development contrasts with the accretion style of
those in low latitudes where the reef rim is first to
grow to sea level.

Abstract
|
This paper proposes the need for new integrated guidance
for a “value-based” approach to facilitate more
sustainable management of global coral reefs and other
coastal resources. Values in this context include not only
economic welfare values, but also a range of other
indicators of value. The paper suggests a series of
supporting principles, frameworks and methodologies
upon which the guidance should be based. Their
application is then discussed with reference to a case
study in American Samoa for which the economic value
derived by residents and visitors to the islands are
estimated to be a minimum US$ 5 million/year (or US$
161 million in total or US$ 0.7/m2) for coral reefs and
US$ 0.7 million/year (or US$ 24 million in total or US$
50/m2) for mangroves respectively. With the inclusion of
non-use values potentially held by the US general public,
the total value of these habitats could be more than
double these figures. Innovative aspects of the study
include a spatial GIS-based approach highlighting the
extent to which values vary spatially, a contingent
valuation study that assesses non-use values, and
consideration of both present and future potential values
under alternative management scenarios. The paper
concludes by highlighting recommendations as to what
further steps need to be taken in development of the new
guidance.

Abstract
|
A census of the commercial fishers of the
U.S. Virgin Islands (USVI) was conducted from July
2003 to January 2004 to determine the socioeconomic
aspects of the fishers and to describe equipment used
in the fishery. USVI fishers had a mean age of 50.5
yrs and on average had fished almost 23 years and
planned to continue to fish for the rest of their lives.
The fishers do not have much education as over 50%
of the fishers had not completed high school. The St.
Thomas/St. John District (NVI) fishery was dominated
by trap fishers catching mainly reef fish and
lobsters. They fished an average 2.6 times per week
during an 8 hrs trip. In contrast, St. Croix District
(STX) fishers were more likely to target pelagic fish
and deep water snappers. NVI fishers have been
fishing longer than STX fishers. NVI fishers are
slightly younger and slightly better educated than STX
fishers. All fishers surveyed were male. More NVI
respondents worked as full time fishers. The fishers
targeted a variety of fin fish and shellfish with the
most common categories being reef fish and coastal
pelagic fish. A wide range of fishing gear including
traps, lines, nets and scuba were used. About 50 NVI
fishers used more than 7,500 fish traps, modified
lobster traps, and plastic lobster traps. In STX, traps
were not as commonly used. Instead fishers diversified
into other gears such as multi-hook vertical
setlines, gill and trammel nets, and scuba. Fishing
using hand lines or less commonly, rods and reels,
was done by most fishers. Fishing was usually performed
in the day.

Abstract
|
In the Ryukyu Islands, southern Japan,
seagrass beds occur in open oceanic and coastal bay
areas. To clarify any differences existing in the fish
assemblage structures between these seagrass bed types,
visual censuses were conducted at four Cymodocea
serrulata-dominated sites in October 2003 and May 2004.
Two sites in the Sekisei Lagoon were selected to
represent exposed oceanic seagrass beds and two sites at
Ishigaki Island for coastal bay seagrass beds. The mean
numbers of fish species and individuals per transect (40
m2) did not differ significantly among the four sites, the
fish assemblage at each comprised seagrass bed residents
and coral reef species. A cluster analysis, based on the
abundance of each species, showed that the similarity of
fish assemblages between the coastal bay and open
oceanic areas was relatively high, with 15 dominant
species contributing over 80% of the total individual
number, indicating that seagrass beds in the Ryukyu
Islands are utilized by a limited number of species.

The Florida Area Coastal Environment (FACE) research program gathers a variety of data related to water inputs into the coastal zone of southeast Florida. The water inputs studied include treated wastewater discharges, inlet flows, and upwelling events. Measurements include currents, nutrients, microbial contaminants, and stable isotopes. This report provides a glimpse of the data collected in this program. Data collected from the Boynton inlet point to the significance of this discharge as a source of nutrient and microbiological loads to coastal waters and demonstrate the importance of accounting for all major discharges in order to fully understand the impact of land use and water management decisions on coastal resources.

Abstract
|
Conservation planning for biodiversity requires spatially
continuous species data that encompasses the area of
interest. Because of the lack of such data in most coral
reef settings, we developed a statistical model to expand
site-specific coral reef fish species counts to continuous
spatial data. Biotic and abiotic reef characteristics were
evaluated in their suitability to serve as predictor
variables. These variables were then applied to our
species distribution model. We used a Generalised Linear
Modelling approach to determine the probability of
occurrence of seven focal fish species in an unsurveyed
patch or habitat. For six out of seven species we derived
suitable models and predicted their presences across the
whole study area of Kimbe Bay, Papua New Guinea. The
resulting data were entered into the reserve selection
software MARXAN, comparing the modelled data with
the original species dataset in their ability to identify
priority sites for conservation in irreplaceability maps.
The species distribution model constituted a powerful tool
to expand limited site records to be used in conservation
planning in conjunction with abiotic and biotic reef
information for a larger planning area. At the same time,
sites with high conservation priority identified by species
data were also identified by modelled data.

Abstract
|
The nursery component in an active reef
restoration program is used as a tool that provides coral
source material for the rehabilitation of denuded reef
areas. Here, we present the first mid-water floating coral
nursery, an improved prototype of earlier attached-tosubstrate
coral nurseries. A total of 7119 fragments
sampled from 11 branching species and 21 intact
colonies of Favia favus were maricultured at six meter
depth, 14 m above sea bottom in close vicinity to fish
farm facilities and 8 km away from the coral nature
reserve, at Eilat, Red Sea. Total mortality of fragments
during 10 nursery months was very low (less the 10%)
while growth rates were high (up to 6 fold in height). The
massive coral F. favus showed zero mortality and an
average growth rate of 159% during 270 nursery days.
We conclude that floating nurseries, installed away from
major reef structures, improve coral culturing as
compared to attached-to-substrate nurseries by providing
better water and nutrient fluxes, promoting the
elimination of sediment, improving cleaning by whole
nursery movements, and providing optimal PAR to
maricultured coral colonies through depth adjustment. In
addition, detrimental impacts caused by recreational
activities and corallivorous organisms are eliminated.

Abstract
|
Increased topographic complexity has been linked to increased species diversity and/or abundance in many ecological communities, including coral reefs. Several topographic metrics can be measured remotely in GIS using high resolution bathymetry, including elevation, surface rugosity, and seafloor volume within specified areas. Statistical relationships between these data and organismal distributions within mapped habitats can be used to make predictions across the entire bathymetric dataset. In this study a model framework is presented which utilizes statistically significant relationships between reef fish abundance and species richness and GIS topographic complexity measurements for samples within similar benthic habitats to create GIS-based prediction maps of abundance and species richness for the entire seascape. Reef fish associations with GIS topographic metrics were significant and varied between habitats. Model evaluation showed that patterns in the measured data emerged in the prediction data. The results allow for viewing of data trends throughout the seascape, quantification of assemblages in non-sampled areas, and statistical comparisons of areas within the region to support and guide management related decisions. This model framework can be adapted to other communities (e.g. benthic organisms) and/or parameters (e.g. diversity) that relate to topographic complexity.

Abstract
|
For geologists, three cores from Lang Bank described at the 1977 ISRS meeting in Miami, FL set the direction of the coral-reef discussion for the next three decades. High accretion rates from this and other Caribbean sites led us to ask why reefs capable of outpacing even the fastest sea-level rise could be abandoned. A possible gap in accretion on Lang Bank at 10,000 CalBP attributed to dirty water flowing off the recently flooded bank provided a solution to this "drowning paradox", and the Lang Bank story was extrapolated to the entire Caribbean. Recent studies suggest that some of the foundational ideas upon which our models were built may warrant reexamination. Acropora palmata reefs not only continued to build, but thrived across the presumed Caribbean-wide gap. Caribbean reef building can generally be characterized as transgressive between 11,000 and 7,000 CalBP due to a steady and rapid rise in sea level, and regressive thereafter, as sea-level rise slowed to below 4 m/Kyr. However, two millennial-scale lapses remain for A. palmata, starting at ca. 6,000 and 3,000 CalBP, respectively, well after sea-level rise had slowed to below the average rate of reef accretion. Their origins remain unknown, but could bear on the species' recent decline.ecies' recent decline.

Abstract
|
The Sekisei Lagoon surrounded by the
Yaeyama archipelago is one of the coral reef areas in
Japan. However, it has been partly damaged due to
several causes. The transport of coral egg and larvae from
the less damaged area would contribute to the recruitment
and recovery in the damaged area. Predicting the
trajectory from such source areas to recruitment areas
will help ascertain the protective area and clarify the
restoration process of the damaged coral reefs on the
basis of the a numerical modeling of flow and dispersion
patterns. We focus on flow patterns both of the whole
Sekisei Lagoon and the area around Kurosima which is
expected as a source area. For this purpose, flow patterns
in summer in the Sekisei Lagoon were examined using a
multi-level hydrostatic model with a two-stepped nesting
approach. The model is driven by the averaged wind
stress in summer and the M2 tidal component. The result
of our model suggests that an effect of south wind in
summer plays most essential role for the transport of
coral eggs and larvae in Sekisei Lagoon. It is supposed
that our numerical model is useful to estimate the
transport course of coral eggs and larvae at the surface
due to barotropic flow at least. In particular, tide inside of
the coral reef around Kurosima does not dominate, but a
drift current by wind rather developed

Abstract
|
A pan-sharpening method for enhancing satellite imagery is proposed as the first step for building a relatively high accuracy and low cost approach for image-based analyses of coral reefs. To achieve this objective, a low spatial resolution multi-spectral image was first spatially resampled (increasing the number of pixels) and co-registered onto a higher resolution panchromatic image. Based on multiple regression analysis, brightness information of the resampled multi-spectral image was replaced with that of the panchromatic image so that all spectral density scatter-diagrams exhibit linear characteristics with slopes equal to one and y-intercepts equal to zero. The method was characterized by its simplicity and faithfulness in preserving spectral (i.e., color) information. Since the resampled multi-spectral pixels were independently modified by the densities of the panchromatic pixels, all information in the panchromatic image was transferred to the resulting pan-sharpened image, thus producing lossless pan-sharpening. As a demonstration, the method was applied to FORMOSAT-2 data acquired on 31 January 2007 at Ishigaki Island, Ryukyu Islands, Japan.

Abstract
|
With the increasing frequency and severity of coral bleaching events, this phenomenon has been documented and studied by scientists around the world. Methods to quantify bleaching status are based on sacrificing the samples being tested or using expensive equipment (like the diving PAM). In recent years, the performance of digital cameras in image processing has improved and they have become more affordable, thus, we used these to develop a new, economical and nondestructive way to monitor bleaching and recovery processes in coral tissues, to be used by conservationists and researchers. In the present study, we report a reliable bioassay for computerized quantification of areal chlorophyll density in corals. We used a regular digital camera and standard computer software, both inexpensive and easily available. The proposed bioassay could be used on any coral to rapidly and economically gather data on coral bleaching and disseminate them.

Abstract
|
In the early 1970s it was observed that some
reef-building corals contained surprisingly high levels of
urea for aquatic invertebrates. A hypothesis was proposed
at the time, whereby hydrolysis of urea might neutralise the
protons formed by deposition of CaCO3, thereby enhancing
the rate of calcification. However, since that early work the
role of urea in coral metabolism has received little
attention. We propose that the primary role of urea is to
allow the coral-zooxanthellae association to take advantage
of episodic peaks in nitrogen availability in an otherwise
nutrient-poor environment. Urea would accumulate during
times of nitrogen excess to be hydrolysed to release
ammonium to the zooxanthellae in times of shortage. An
increase in calcification rates could be a beneficial sideeffect
of a pulsed nitrogen supply. Preliminary testing of
this hypothesis has shown 1. that urea concentrations can
be measured in a field laboratory using a colorimetric kit
designed for use with human blood plasma 2. that urea
concentrations increase significantly in corals exposed to
ammonium pulses and return to those of control corals in
low-ammonium seawater, 3. that calcification rates in
corals exposed to a pulse of ammonium tend to increase
relative to controls in low-nutrient seawater. We predict
that, under conditions of chronically elevated nitrogen, if
urea concentrations in the coral exceed a threshold level,
then a decline in growth and health of the coral could
follow. The levels of urea in coral tissue may provide
another tool by which the nitrogen sufficiency of a coral
might be monitored.

Abstract
|
Studies have shown that marine biofilms play an important role in coral larval settlement. Biofilms are formed when substrata are immersed in seawater over a period of time in a process known as conditioning. This study investigated the settlement of Pocillopora damicornis larvae on concrete tiles which had been conditioned in running seawater for one, two, four, six and eight weeks, with unconditioned tiles used as controls. Results showed that larval settlement appeared to be higher on unconditioned tiles. Two-way ANOVA indicated no significant differences in larval settlement densities in treatments and controls, but significant differences in the choice of settlement surfaces preferred. Larvae preferred to settle on the sides of the tiles, compared to the top and bottom surfaces. Regression analysis conducted on the weight of sediment accumulated and the density of settled larvae indicated a negative and significant correlation between the two variables. Sediment accumulation on biofilm layers growing on underwater substrata likely affects the suitability of these surfaces for larval settlement. This factor must be taken into account when designing artificial surfaces to enhance coral larval settlement for reef rehabilitation.

Abstract
|
colonies spreading over reef slopes and lagoons, exist in
a variety of marine environments including seagrass
beds in moats, sargassum beds formed on dead coral
skeletons, or mangrove forests in estuaries. In the coastal
waters of Okinawa, coral reefs have been playing crucial
roles in providing rich marine biota. However, their area
of habitation is now diminishing due to the impact of
increasing coastal reclamation and land development.
Our study has thereby been directed to explore the
technologies needed to restore the marine and coastal
environment, in particular the ones applicable to
restoring coral reefs and seagrass beds. In an attempt to
explore the comprehensive management strategies for
coral reefs, this experimental study was conducted on
seagrass growing in moats, focusing on the different
characteristics of the growth processes and the habitat
conditions of each seagrass species as well as the
symbiotic relationship between corals and Thalassia
hemprichii. The seagrass plants were transplanted using
both conventional and newly developed methods, and
monitored to examine their effectiveness. Materials
capable of facilitating coral settlement, were also utilized
for the fixation of seagrass, and examined for their
workability.

Abstract
|
Bacteria of the genus Vibrio have been implicated in coral bleaching as well as diseases, including Caribbean Yellow Band Disease (CYBD). Four Vibrio species have been previously identified as causative agents of CYBD through a series of infection and re-isolation experiments. The mechanisms of pathogenesis and the dynamics of the Vibrio community as a whole during CYBD infection are poorly understood. In order to elucidate the role of Vibrios in CYBD, a survey of Vibrio species associated with healthy corals and CYBDinfected corals was conducted using a culture-based approach. Fragments were collected from CYBD lesions of five Montastraea faveolata colonies, five healthy regions of the same diseased colonies, and five entirely healthy colonies. Samples were serially diluted and plated onto TCBS agar to differentially select for Vibrio species. Colonies were subcultured using GASWA media and a total of 391 isolates were identified by 16S rDNA sequence analysis. Phylogenetic analysis of Vibrio spp. communities of healthy and diseased corals illustrated a shift from isolates taxonomically affiliated with V. fortis dominating in healthy corals to isolates taxonomically affiliated with V. harveyi, a known marine pathogen, dominating in diseased corals. There was a similar shift to isolates taxonomically similar to Photobacterium eurosenbergii as corals progressed to diseased states. However, our study did not find any Vibrio species that are always present in CYBD lesions and absent from healthy samples.

Abstract
|
Twenty-eight coral reef Marine Protected
Areas (MPAs) in East Africa, East Asia, the South
Pacific, and the Wider Caribbean were surveyed to
assess reef threats, and management, education, and
outreach needs of various stakeholders. Respondents
answered over 40 questions in a written survey.
Results show that the three biggest challenges sites
face are financial support (13 sites), staff shortages
(nine sites), and enforcement of regulations (four sites).
Our findings also show that the three most critical
issues facing the sites, as perceived by the respondents,
are over-fishing and destructive fishing (22 sites),
followed by tourism impacts (14 sites), and sewage and
waste disposal (14 sites). This paper will present
detailed results from the survey and offer
recommendations that will assist efforts to foster
management effectiveness and improve coral reef
conservation.

Abstract
|
The activities of two antioxidant enzymes, superoxide dismutase (SOD) and catalase (CAT), were studied in a colony of Galaxea fascicularis corals with increased concentrations of hydrogen peroxide (H2O2) in seawater using an incubation chamber. Changes in enzyme activity were compared to those induced by increased seawater temperature. Three H2O2 concentrations (0, 0.3, and 3.0 µM) were tested at 27oC, and an elevated seawater temperature of 31oC was tested without added H2O2. CAT activities in both coral tissue and zooxanthellae increased with increased H2O2, but SOD activities remained relatively unchanged, suggesting that increased H2O2 in seawater affected coral cytosol but did not induce superoxide formation. In contrast, the elevated seawater temperature caused both SOD and CAT activities in coral tissue and zooxanthellae to increase. Coral bleaching was not observed at the levels of H2O2 tested during the 5-day exposure period. Although the long-term effects of H2O2 remain unknown, these results suggest that coral bleaching would likely not occur from short-term (5 days) exposure to increased H2O2 concentrations in seawater.

Abstract
|
Recent evidence suggests that, as global climate changes and seawater temperatures rise, the primary cause of coral bleaching is zooxantheallar mortality indicated by cell apoptosis/necrosis. But are the coral hosts themselves sensitive to increasing temperatures, and, if so, to what degree? We exposed the coral Favites complanata (Ehrenberg, 1834) with their symbiotic zooxanthellae (Symbiodinium sp.) to experimental temperatures of 28 (control), 30, 32, and 34°C for 12h. We assessed coral and symbiont cells in situ for symptoms of apoptosis and necrosis using transmission electron microscopy (TEM). F. complanata host cells in situ exhibited little or no mortality from exposure to increased seawater temperatures, except at very high temperatures (34°C) for >12hrs. By contrast, we found high levels of apoptosis/necrosis in the zooxanthellae in situ under all experimentally elevated temperatures. These findings indicate that the host corals are adapted/exapted to seawater temperature increases. They also imply that the coral hosts do not suffer mortality from temperature stress but from loss of their symbionts – a process driving natural selection in Symbiodinium and most likely resulting in their rapid adaptation to a changing environment.

Abstract
|
A synoptic perspective of reef biogeochemical dynamics and community structure was revealed using new technologies and methods designed to enable high resolution underwater habitat assessment with non-invasive monitoring capabilities and rapid information output. A towed, chemical sensor platform (TETHYS) and a diver-based, benthic imaging system (SCUBA COP) were developed to compare reef architecture and seafloor morphology across centimeter to kilometer spatial scales, and resolve sub-meter variability in ambient water chemistry across 300 km seascapes. Acoustic bathymetry, stereo-optical imaging, in-situ underwater mass spectrometry, and fluorometry data were coupled with precision navigation to enable multi-parameter biogeochemical and structural comparisons of coastal and island coral habitats surrounding Coiba Island, a UNESCO World Heritage site in Pacific Panamá. Baseline chemical data [O2, CO2, CH4, N2]; and digital 3-D reef mosaics were coupled with SCUBA diver transect data, High Definition video, oceanographic time series from a cabled underwater observatory, Landsat and SeaWiFs satellite imagery to create and validate comprehensive, thematic chemical and benthic habitat maps. This integrated approach shows considerable promise for locating, predicting and quantifying natural and anthropogenic environmental stressors affecting the distribution, diversity and health of tropical coral communities.

Abstract
|
Various targets aiming to protect proportions of
marine ecosystems ranging from 10-30% of their total
area have been adopted by national governments and
conservation professionals. Efforts to assess the baseline
provided by existing marine protected areas (MPAs) and
to track progress towards achieving these targets both
require the measurement of the proportion of marine
ecosystems presently occurring within the boundaries of
MPAs. The planning of new MPAs and the design of
future regional scale MPA networks also require
information on the distribution of protected marine
ecosystems. Therefore, in the first ecosystem-based
analysis of MPAs, maps of coral reefs and tropical
shallow-water habitats (SWH) were analysed with spatial
data on MPA location and boundaries. Presently 52,800
km2 (19%) of the world’s coral reefs and 404,400 km2
(7%) of tropical SWH is theoretically protected by being
incorporated within the boundaries of MPAs. These
proportions, while broadly in line with targets being
adopted, are deceptively high in terms of biodiversity
conservation. Most protected coral reef (72%) and
tropical SWH (45%) is within one protected area, the
Great Barrier Reef Marine Park and, until July 2004,
worldwide 41% were managed under regimes which can permit destructive activities. The rest occurs in hundreds
of small MPAs (median size 5km2) with pronounced
regional differences in the proportion protected. We
assess the existing collection of coral reef MPAs as a
