Como suele suceder últimamente, cuando se acerca el final de año aparecen una serie de listas, que recogen lo mejor del año que termina, pero también todo tipo de predicciones respecto al año que empieza. Es el caso de la ya habitual publicación del color del año por parte de la empresa Pantone: el color del 2019 será el living coral. ¿No lo conoces?

Live Coral Cover

The existence of coral reef fish is closely related to the availability of coral reef resource as a habitat. Coral reef fish is a biota that has a fascination with a variety of color patterns and fascinating. Differences in coral cover conditions will affect the abundance of coral reef fish, especially those with strong linkages to living corals. This research was conducted in June - August 2017 by using line intercept transect (LIT) method for coral cover percentage and visual census method for biodiversity and biomass of coral reef fish with 3 research stations in Manggis waters, Karangasem. From the research results, it shows that the diversity index ranged between 2.54 - 2.70 which means the diversity of coral reef fish in the medium category and the stability of the community is in the medium. Furthermore, total biomass of coral reef fish ranged between 186,17 - 1692,08 kg / ha. The results stated that the percentage of live coral cover in Manggis waters ranged from 3.83% to 12.44% which means that live coral cover is categorized as bad. A very strong positive correlation between living coral conditions and coral reef fish biomass was 92.42%. Meanwhile, the relationship between living coral conditions and the diversity of coral reef fish had a strong positive correlation of 65.4%. The diversity of coral reef fish in waters is not only caused by live coral cover; however, it is caused by coral reef ecosystems that are associated in the bottom of the waters.

Demand of the construction industry for coral rock in the Maldives will soon reach the limit of supply capacity using existing collection techniques. It is estimated that, at the current rate of consumption, the supply of living coral rock from inner atoll ‘faros’ in North Malé will be exhausted within 30 years. Current mining practice has already necessitated the collection of living coral rock from outer atoll ‘faros’ which actually protect the integrity of the islands against the erosive influences of monsoon storms.Biological surveys of mined sites (compared with controls where no mining activity has taken place) indicate a dramatic reduction in coral variety and abundance and in some cases an almost total depletion of living coral after mining. At intensively-mined sites, diversity and abundance of coral-reef fishes is also markedly reduced, with some reef species commonly used as baitfish entirely absent. The time taken for reefs to recover from mechanical damage has been shown by other research work to be extremely variable, with some cases showing no recovery in some circumstances. Shallow-water reefs that have been colonized by slow-growing ‘massive’ corals, such as those which have been mined in the Maldives, may take a minimum of 50 years to recover to their former state—under optimum conditions.Observations on mined reefs in the Maldives show that recovery over the last 10 years has been minimal, and therefore suggest that recovery times may be much in excess of 50 years. Indeed many of these reefs may not recover at all unless some attempts are made to re-establish corals at these sites. It is also clear from the study of reclaimed and dredged sites and those where less-intensive mining has taken place, that regeneration of corals is occurring. It is quite probable that the rate of recovery is dependent on the intensity of the disturbance which initially took place.Alternative building materials are available in the form of concrete blocks. Use of these blocks is more cost-effective than use of coral rock; however, there is a lack of any quality control, which would be needed to promote the widespread use of concrete blocks as a substitute for coral. Recently, recommendations have been approved by the Government of Maldives for the execution of a feasibility study on mining an inner atoll faro which could potentially provide building material for as long as the next 500 years.

Abstract Embedding and immobilisation of living cells and microorganisms is used in a variety of research and commercial applications. Here we report the successful extended immobilisation of coral larvae in a low-gelling temperature agarose. Embryos and larvae of five broadcast-spawning Scleractinian species were immobilised in agarose gel and tested in a series of exploratory survival and settlement assays. The optimal developmental stage for immobilisation was after ciliation at approximately 24 hours post-fertilisation, after which, survival of immobilised larvae of all species was nearly 100%. In long-term assays, 50% of Montipora digitata larvae survived immobilised for 89 days. Furthermore, immobilised larvae of multiple species, that were released from the agarose, generally remained capable of settlement. These results demonstrate that the immobilisation of the early life-history stages of corals is possible for a variety of applications in basic and applied science.

Coralliophila Abbreviata

The importance of the stenoglossan prosobranch gastropod Coralliophila abbreviata (Lamarck) and the amphinomid errant polychaete Hermodice carunculata (Pallas) as coral predators in Barbados, West Indies, was investigated. Coralliophila normally feeds upon the coral Montastrea annularis (Ellis and Solander), can consume up to 9 cm2 of tissue in 24 h, and has a mean density of 13 individuals per square meter of living coral in shallow water. Hermodice normally feeds upon the zooanthid Palythoa mammillosa (Ellis and Solander) and the corals Porites porites (Pallas) and Porites astreoides Lamarck. The mean density of Hermodice was less than one individual per square meter of surface of living prey and large worms could consume up to 3 cm2 of living coral tissue in a 3-h feeding period. Because of the low densities of the predators the preference of Hermodice for the zooanthid Palythoa and the fact that Coralliophila feeds only rarely, they did not cause extensive damage to reef corals.

Management And Conservation

This research aims to know the percentage of living coral cover in the village of Sepagar. The benefits of this research are as input for the parties involved in the efforts of the management and conservation of coral reefs in the waters of the village Sepagar. The results of the observation and calculation of the coral reefs is done using the method of Point Intercept Trancek (PIT) shows that the community of coral reefs in the waters of the Sepagar included in the types of coral reefs of the sandbar (patch reef). Generally burnt coral reefs grow and develop in the relatively shallow waters with depths ranging from 1-5 meters. The results showed on the three stations found 7 of the 10 components of the reef that is. Acropora (AC), Non-Acropora (NA), Dead Coral with Algae (DCA), Dead Coral (DC), Soft Coral Sand (SC) (S), and the Rubble (R). Component not found is Fleshy Seawed (FS), Rock (RK) and Silt (SL). At station 1, the total percentage of living coral closure (living cover) by 51.4%, In station 2 of 55,3 % , and in station 3 of 51.3 % .The percentage the coral lived in waters sepagar in good not far different the percentage the coral live in every station.
