Vibrio alginolyticus 16S-23S intergenic spacer region analysis, and PCR assay for identification of coral pathogenic strain XSBZ03.

Porites andrewsi white syndrome (PAWS), caused by Vibrio alginolyticus strains XSBZ03 and XSBZ14, poses a serious threat to corals in the South China Sea. To obtain a specific target against which to develop a rapid PCR detection method for the coral pathogenic strain XSBZ03, the 16S-23S rRNA gene intergenic spacer (IGS) region of 4 strains of V. alginolyticus, including the XSBZ03 and XSBZ14 strains, was amplified, sequenced and analyzed. Six types of IGS were found: IGS0, IGSG, IGSIA, IGSAG, IGSGLV, and IGSGLAV. IGS0, IGSG, IGSIA, IGSAG and IGSGLV appeared to be the most prevalent forms in the 4 strains and the percentage identity range within each type was 91.4-100%, 89.3-98.5%, 83.0-99.8%, 91.5-95.6%, and 88.7-99.3%, respectively. IGSGLAV was found only in the HN08155 strain, a causative agent of fish disease. IGSGLAV, IGSGLV and IGSAG are reported here for the first time in V. alginolyticus. An IGS sequence specific to the XSBZ03 strain was identified following alignment of the homologous IGSs, and used to design strain-specific primers for its rapid identification by PCR. The results from PCR analysis suggest that the method is a rapid, practical, and reliable tool for the identification of the XSBZ03 strain in samples of isolated bacteria, as well as seawater and coral samples spiked with the bacterial strain. This is the first report of a rapid diagnostic assay for a causative agent of PAWS, based on PCR detection of a coral pathogen at the strain level. After applying this assay in coral transplantation, the survival rates of transplanted corals were significantly increased. This diagnostic assay should aid with both the elucidation of the cause of the disease, and transplantation of PAWS-free P. andrewsi in the South China Sea.

Implications of coral harvest and transplantation on reefs in northwestern Dominica

In June, 2002, the government of Dominica requested assistance in evaluating the coral culture and transplantation activities being undertaken by Oceanographic Institute of Dominica (OID), a coral farm culturing both western Atlantic and Indo-Pacific corals for restoration and commercial sales. We assessed the culture facilities of OID, the condition of reefs, potential impacts of coral collection and benefits of coral transplantation. Coral reefs (9 reefs, 3-20m depth) were characterized by 35 species of scleractinian corals and a live coral cover of 8-35%. Early colonizing, brooders such as Porites astreoides (14.8% of all corals), P. porites (14.8%), Meandrina meandrites (14.7%) and Agaricia agaricites (9.1%) were the most abundant corals, but colonies were mostly small (mean=25cm diameter). Montastraea annularis (complex) was the other dominant taxa (20.8% of all corals) and colonies were larger (mean=70cm). Corals (pooled species) were missing an average of 20% of their tissue, with a mean of 1.4% recent mortality. Coral diseases affected 6.4% of all colonies, with the highest prevalence at Cabrits West (11.0%), Douglas Bay (12.2%) and Coconut Outer reef (20.7%). White plague and yellow band disease were causing the greatest loss of tissue, especially among M. annularis (complex), with localized impacts from corallivores, overgrowth by macroalgae, storm damage and sedimentation. While the reefs appeared to be undergoing substantial decline, restoration efforts by OID were unlikely to promote recovery. No Pacific species were identified at OID restoration sites, yet species chosen for transplantation with highest survival included short-lived brooders (Agaricia and Porites) that were abundant in restoration sites, as well as non-reef builders (Palythoa and Erythropodium) that monopolize substrates and overgrow corals. The species of highest value for restoration (massive broadcast spawners) showed low survivorship and unrestored populations of these species were most affected by biotic stressors and human impacts, all of which need to be addressed to enhance survival of outplants. Problems with culture practices at OID, such as high water temperature, adequate light levels and persistent overgrowth by macroalgae could be addressed through simple modifications. Nevertheless, coral disease and other stressors are of major concern to the most important reef builders, as these species are less amenable to restoration, collection could threaten their survival and losses require decades to centuries to replace.

Reef Development on Artificial Patch Reefs in Shallow Water of Panjang Island, Central Java

Reef restoration methods are generally developed by propagation of coral fragments, coral recruits and provide substrate for coral attachment using artificial reefs (ARs). ARs have been widely applied as a tool for reef restoration in degraded natural reefs. Successful of coral restoration is determined by reef development such as increasing coral biomass, natural of coral recruits and fauna associated. Artificial Patch Reefs (APRs) is designed by combined of artificial reefs and coral transplantation and constructed by modular circular structures in shape, were deployed from small boats by scuba divers, and are suitable near natural reefs for shallow water with low visibility of Panjang Island, Central Java. Branching corals of Acropora aspera, Montipora digitata and Porites cylindrica fragments were transplanted on to each module of two units of artificial patch reefs in different periods. Coral fragments of Acropora evolved high survival and high growth, Porites fragments have moderate survival and low growth, while fragment of Montipora show in low survival and moderate growth. Within 19 to 22 months of APRs deployment, scleractinian corals were recruited on the surface of artificial patch reef substrates. The most recruits abundant was Montastrea, followed by Poritids, Pocilloporids, and Acroporids. We conclude that artificial patch reefs with developed by coral fragments and natural coral recruitment is one of an alternative rehabilitation method in shallow reef with low visibility.

SINTASAN DAN PERTUMBUHAN TRANSPLANTASI KARANG HIAS ACROPORA SP DI DESA TONYAMAN, KECAMATAN BINUANG, KABUPATEN POLEWALI MANDAR

Culture of ornamental corals applying transplantation technique was aimed to know the successful of this transplantation technique in the ornamental coral culture based on its growth and survival rate of various coral fragments. The location of the medium settlement was in the western side of the waters of Tonyaman Village, Binuang Subdistrict, Polewali Mandar Regency with 3-4 meter depth during low tide. One of coral species i.e. Acropora sp with 48 fragments was put on 4 transplantation tables. During the experiment, cleaning of fungi and biofouling at the transplant tables and the culture tables. Measurements of the absolute growth and survival rate were done at the 21st day using calliphers and numbers of dead and live fragments were counted directly. Coral transplantation workshop for ornamental coral culture was attended by 4 fisherman groups with total 23 participants. This event was understood by the training participants from the seed selection to the monitoring. Number of coral fragment cultured was 48 fragments obtained from one of stony corals (Scleractania), i.e. Acropora sp. The range of survival rate that has been cultured for 21 days was adequately high i.e. 91.7 – 100 %. The highest survival rate was observed at the transplant table B, i.e. 100%, whereas, the table A, C, and D were 91.7 %. Average absolute growth of the coral Acropora sp cultured during this study were ranged from 4.2 – 4.9 mm/month.

Laju Pertumbuhan dan Tingkat Kelangsungan Hidup Transplantasi Karang Acropora secale di Pantai Serangan dan Pantai Geger, Bali

The status of Indonesian coral reefs are in fair to poor categories, therefore it requires more approaches in order to recover the natural ecosystem. One of the reef restoration method is coral transplantation. Genus Acropora is one of the main constituent of reefs in the Indo-Pacific waters. Reef transplantation may not only rehabilitate the damaged reef, but also an effective way to collect coral for economic purposes. Acropora secale has high economic value as aquarium ornament, however it is vulnerable to the environmental stress and marine pollution. Therefore, finding the suitable transplantation location is one of important part in the transplantation. The objective of this research is to investigate the growth of transplant A. Secale at Serangan and Geger Beach which has different morphology feature. A. secale was Transplanted for 3 months on the 2 x 1 m table with 16 fragments and observed each week. The results obtained are total growth and growth rate of A. secale transplanted on Serangan Beach is significant higher than Geger Beach (P<0.05). The total growth of A. secale on Serangan Beach is higher by 0,83 cm, wider by 0,61 cm, and branches are more 7 branches than Geger Beach. The growth rate of A. secale at Serangan Beach was higher by 0,27 cm/month and wider by 0,21 cm/month than Geger Beach. The survival rate of A. secale on Serangan Beach and Geger Beach is 100% which means that all transplanted corals survive until the end of the study.

Rehabilitation of damaged reefs: Outcome of the use of recently broken coral fragments and healed coral fragments of pocilloporid corals on rocky boulders

AbstractThe use of two types of coral transplants on rock boulders was evaluated as a low‐cost alternative for rehabilitation of live coral coverage in localities whose reef structure has been reduced considerably. Transplant success between recently broken coral fragments (BCF) and healed coral fragments (HCF) was compared assuming that initial fragmentation accelerates the attachment of corals by regeneration stimulation. Two sets of both types of transplants were started during the dry and rainy seasons to contrast the effect of environmental stability on transplant survival, vertical growth and horizontal growth over 12 months. The technique provided adequate conditions for coral development, as transplants responded satisfactorily. BCF showed higher success than HCF in attaching to the substrate (up to 98 ± 4% versus 86.4 ± 18.9% after 9 months) during both seasons and also showed a greater increase in height (209.63 ± 43.65% versus 124 ± 15.83%) and diameter (107.26 ± 25.75% versus 99.98 ± 19.74%) during the rainy season. Boat anchorage caused mortality in transplants started during the dry season (less than 10% for BCF versus 37.2% for HCF) while the impact of Hurricane Polo in October 2014 caused higher mortality in transplants started during the rainy season (up to 55%). We conclude that (i) coral transplantation on rock boulders is a good choice to restore damaged coral communities, (ii) BCF seems to be the best source of transplants for pocilloporid corals, and (iii) although high light availability during the rainy season enhances transplant growth, the stable, low energy conditions in the dry season facilitate initial transplant attachment and high survival.

The need for broader ecological and socioeconomic tools to evaluate the effectiveness of coral restoration programs

Coral reef restoration initiatives are burgeoning in response to the need for novel management strategies to address dramatic global declines in coral cover. However, coral restoration programs typically lack rigor and critical evaluation of their effectiveness. A review of 83 peer‐reviewed papers that used coral transplantation for reef restoration reveals that growth and survival of coral fragments were the most widely used indicators of restoration success, with 88% of studies using these two indicators either solely (55%) or in combination with a limited number of other ecological factors (33%). In 53% of studies, reef condition was monitored for 1 year or less, while only 5% of reefs were monitored for more than 5 years post‐transplantation. These results highlight that coral reef restoration science has focused primarily on short‐term experiments to evaluate the feasibility of techniques for ecological restoration and the initial establishment phase post‐transplantation, rather than on longer‐term outcomes for coral reef communities. Here, we outline 10 socioecological indicators that comprehensively evaluate the effectiveness of coral reef restoration across the four pillars of sustainability (i.e. environmental, sociocultural, governance, and economic contributions to sustainable communities). We recommend that evaluations of the effectiveness of coral restoration programs integrate ecological indicators with sociocultural, economic, and governance considerations. Assessing the efficacy of coral restoration as a tool to support reef resilience will help to guide future efforts and ensure the sustainable maintenance of reef ecosystem goods and services.

In situ nurseries enhance coral transplant growth in sedimented waters

ABSTRACTIn situ nurseries have been a crucial part of coral reef restoration initiatives for the past two decades. However, the advantages over direct transplantation in sedimented waters has yet to be examined. In the present study, we showed that Pachyseris speciosa and Pocillopora damicornis fragments reared in in situ nurseries (NR) in Singapore’s sedimented waters grew significantly faster (by three to five times) than those which were directly transplanted (DT) onto the substrates. The increased growth rate during the nursery phase augmented the size of NR transplants, and had a flow-on effect on their performance during the post-transplantation phase. Overall, the maximum diameter of the NR transplants was 1.8–2.7 times larger than DT transplants after 11 months. The growth enhancement of the nursery-reared transplants improved the cost-effectiveness of our restoration effort: the estimated cost per centimetre growth of NR transplants was one-fifth of the DT corals despite the additional costs incurred to construct the nurseries. These results highlight that coral nurseries are beneficial to reef restoration in chronically sedimented waters.

Effectiveness of coral relocation as a mitigation strategy in Kāne'ohe Bay, Hawai'i.

Coral reef restoration and management techniques are in ever-increasing demand due to the global decline of coral reefs in the last several decades. Coral relocation has been established as an appropriate restoration technique in select cases, particularly where corals are scheduled for destruction. However, continued long-term monitoring of recovery of transplanted corals is seldom sustained. Removal of coral from a navigation channel and relocation to a similar nearby dredged site occurred in 2005. Coral recovery at the donor site and changes in fish populations at the receiving site were tracked periodically over the following decade. Coral regrowth at the donor site was rapid until a recent bleaching event reduced coral cover by more than half. The transplant of mature colonies increased spatial complexity at the receiving site, immediately increasing fish biomass, abundance, and species that was maintained throughout subsequent surveys. Our research indicates that unlike the majority of historical accounts of coral relocation in the Pacific, corals transplanted into wave-protected areas with similar conditions as the original site can have high survival rates. Data on long-term monitoring of coral transplants in diverse environments is central in developing management and mitigation strategies.

Effects of predation and nutrient enrichment on the success and microbiome of a foundational coral.

By inflicting damage to prey tissues, consumer species may increase stress in prey hosts and reduce overall fitness (i.e., primary effects, such as growth or reproduction) or cause secondary effects by affecting prey interactions with other species such as microbes. However, little is known about how abiotic conditions affect the outcomes of these biotic interactions. In coral reef communities, both nutrient enrichment and predation have been linked to reduced fitness and disease facilitation in corals, yet no study to date has tested their combined effects on corals or their associated microbial communities (i.e., microbiomes). Here, we assess the effects of grazing by a prevalent coral predator (the short coral snail, Coralliophila abbreviata) and nutrient enrichment on staghorn coral, Acropora cervicornis, and its microbiomes using a factorial experiment and high-throughput DNA sequencing. We found that predation, but not nutrients, significantly reduced coral growth and increased mortality, tissue loss, and turf algae colonization. Partial predation and nutrient enrichment both independently altered coral microbiomes such that one bacterial genus came to dominate the microbial community. Nutrient-enriched corals were associated with significant increases in Rickettsia-like organisms, which are currently one of several microbial groups being investigated as a disease agent in this coral species. However, we found no effects of nutrient enrichment on coral health, disease, or their predators. This research suggests that in the several months following coral transplantation (i.e., restoration) or disturbance (i.e., recovery), Caribbean acroporid corals appear to be highly susceptible to negative effects caused by predators, but not or not yet susceptible to nutrient enrichment despite changes to their microbial communities.

Coral Transplantation Technology for Sustainable Fisheries and Underwater Tourism

Large-scale coral reef restoration could assist natural recovery in Seychelles, Indian Ocean

The aim of ecological restoration is to establish self-sustaining and resilient systems. In coral reef restoration, transplantation of nursery-grown corals is seen as a potential method to mitigate reef degradation and enhance recovery. The transplanted reef should be capable of recruiting new juvenile corals to ensure long-term resilience. Here, we quantified how coral transplantation influenced natural coral recruitment at a large-scale coral reef restoration site in Seychelles, Indian Ocean. Between November 2011 and June 2014 a total of 24,431 nursery-grown coral colonies from 10 different coral species were transplanted in 5,225 m2 (0.52 ha) of degraded reef at the no-take marine reserve of Cousin Island Special Reserve in an attempt to assist in natural reef recovery. We present the results of research and monitoring conducted before and after coral transplantation to evaluate the positive effect that the project had on coral recruitment and reef recovery at the restored site. We quantified the density of coral recruits (spat <1 cm) and juveniles (colonies 1-5 cm) at the transplanted site, a degraded control site and a healthy control site at the marine reserve. We used ceramic tiles to estimate coral settlement and visual surveys with 1 m2 quadrats to estimate coral recruitment. Six months after tile deployment, total spat density at the transplanted site (123.4 ± 13.3 spat m-2) was 1.8 times higher than at healthy site (68.4 ± 7.8 spat m-2) and 1.6 times higher than at degraded site (78.2 ± 7.17 spat m-2). Two years after first transplantation, the total recruit density was highest at healthy site (4.8 ± 0.4 recruits m-2), intermediate at transplanted site (2.7 ± 0.4 recruits m-2), and lowest at degraded site (1.7 ± 0.3 recruits m-2). The results suggest that large-scale coral restoration may have a positive influence on coral recruitment and juveniles. The effect of key project techniques on the results are discussed. This study supports the application of large-scale, science-based coral reef restoration projects with at least a 3-year time scale to assist the recovery of damaged reefs.

THE ABUNDANCE OF ORNAMENTAL CORALS AFTER MASS DIE OFF IN 1997 ON THE PADANG SHELF REEF SYSTEM, WEST SUMATERA, INDONESIA

ABSTRACTThe Indonesian Ministry of Marine Affairs and Fisheries aims to establish export quota ornamental corals based on scientifically-founded data from the natural environment. The purpose of this study was to determine the abundance of ornamental coral after mass die off in 1997. Ornamental corals were classified into three groups based on the guideline of ornamental coral propagation for trading purposes. Classification categories are rapid (3-6 months), middle (8-12 months), and slow growth rate (>24 months), which relates to their harvesting time when transplanted for the trade purpose. The survey method used line intercept transects to get coral condition data and belt transect with 2 m width to get ornamental coral data. Both line and belt transect have 30 m length and with three replicates. The study showed number of colony and abundance of ornamental coral for fast growth rate group such as Acropora sp (1348 col & 7.49 col/m2), Galaxea sp, Hydnophora exesa, H. microconus, Pocillopora damicornis, Stylopora sp and Montipora sp with the highest abundant found on Acropora sp and Montipora sp (1348 col & 7.49 col/m2). Whereas the coral which from middle growth rate were Leptoseris sp, Pavona sp, Platygyra sp, Favia sp, Favites sp with the highest abundant found on Favia sp (101 col & 0.56 col/m2). Coral species typically used for ornamental coral trade within the slow growth rate category such massive coral were not found on this survey. Due to the massive coral die-off in 1997 and the paucity of ornamental corals, the utilization of ornamental coral should be supported by coral transplantation and the broodstock of slow growth of coral taken from other area.

Effects of substratum on the growth and survivorship of Montipora capitata and Porites lobata transplants

Artificial transplantation of corals is a common method used to restore damaged or unhealthy coral assemblages. Though a number of studies have successfully transplanted coral fragments, there is no general consensus on the type of substratum to be used. The present study focused on the growth and survivorship of Montipora capitata (rice coral) and Porites lobata (lobe coral) fragments, which were transplanted onto different natural and synthetic substrata. No significant differences in coenosarc tissue growth or survivorship were observed between the species. Measurements after 184days of growth, found transplant growth to be significantly higher on rhyolite breccia and amorphous coral skeletons than on black ʻAʻā lava. Nevertheless, no significant differences were observed between any of the other substrata. After 365days of growth, survivorship was also observed to not be significantly different between substrata; with the only exception of being lower on glass substratum. It is hypothesized that success in a coral reef restoration project is largely determined by the actual coral fragmentation and transplantation process; as no distinct substratum affinity was observed for M. capitata and P. lobata transplants.

The effects of four transplantation methods on five coral species at the Sanya Bay

Coral transplantation is considered as one of the major tools to increase coral abundance for degraded coral reefs. To investigate the effects of various methods and coral species in transplantation, coral fragments (n=902) of five coral species were transplanted by four methods at Luhuitou, the Sanya Bay, Hainan Province, China, where the reef has been over-exploited and is still threatened by human activities and natural disasters. Ten months after the transplant, the average survivorship of the transplanted corals was 45.5%. Methodologies had different effects on the transplanted corals, but none of them was efficacious for all coral species. Methodology could not change the decreasing trend for Montipora foliosa and Acropora hyacinthus, although it did slow down their decline. All transplants of A. hyacinthus and M. foliosa had high mortalities and significant decrease on survival area, while Porites andrewsi and Galaxea fascicularis had lower mortalities and partial mortalities. Only one method had significant effect on increasing survival area of G. fascicularis, same as P. andrewsi. Out of the five transplanted coral species, Pocillopora damicornis was the only species that had living tissue area increase in all applied methods, while the others had decreased live tissue area in one or more methods. The results of this study suggested that performing coral transplantation in a highly threatened area was not efficient unless the threats were diminished or erased. Moreover, proper species selection for coral transplantation is crucial, especially in a disturbed environment. Methodology, although having limited effects on improving results of coral transplantation, cannot compensate the maladjustment of vulnerable species to the stresses on the Luhuitou Reef. Coral transplantation on Luhuitou Reef should not be performed unless the stresses are under controlled, and corals with good tolerance to the environment should be considered first.

Peningkatan Mutu Sumber Daya Manusia melalui Pelatihan Budi Daya Rumput Laut dan Berbagai Makanan Olahannya, serta Pengelolaan Terumbu Karang Guna Peningkatan Potensi Daerah Menuju Kemandirian di Kec. Laonti Kab. Konawe Selatan

This program was carried out in the Tambolosu and Rumbi-Rumbia villages which is a coastal village in district of South Konawe. As a coastal village communities would have been very different characteristics with the majority of the land village. It is a fact that the majority of people in these villages are working as fishermen, so they financial life is dependent on the fishery resources. Meanwhile the high potential of coastal resources are not comparable with the quality of human resources. The purposes of these service community are to enhance participation of target community to make a coastal and marine resources management, namely, coral reefs, sea grass, and fish. The second aim are for Halu Oleo students who joint in this program for make problem solving in the society with related with they college material. There are four programs was done, namely seaweed cultivation by using long line methods, restoration of coral reefs through artificial reefs and coral transplants, and the last program is manufacture of processed food made from seaweed and fish (seaweed chips, fish meatballs, legs dragon, and cendol seaweed ice. The method used observation and experimentation, analysis techniques using qualitativede scriptive method. The Results of the community services by Halu oleo lecturer are the level of community participation is in the high level in both villages as the target society. Participation of the target society were also seen with the good cooperation with students for example for determining site selection and placement in the waters for artificial reef and coral transplantation. In addition both villages of target by fisheries and marine sains faculty will be a “village built” to sustainability in order to achieve public welfare activities.
