Coral reefs

The study on coral reef fish species composition in the coastal areas of North Hai Van - Son Cha, Thua Thien Hue province was carried out in the period from January, 2020 to October, 2022 at 4 sites, namely Bai Ca, Bai Chuoi, Sung Rau Cau, Son Cha island to update scientific data to contribute to establishing the marine reserve.

Recent advancements in metagenomics, particularly in the studies of conservative 16S rRNA sequences, have significantly accelerated our understanding of the relationship between corals and their associated microbial communities. While bacteria are known to be closely linked with corals, there is limited understanding of the connections between archaea and corals. Unlike previous 16S rRNA studies conducted in similar tropical coral reef ecosystems, we analyzed both the archaeal and bacterial communities associated with Acropora sp. and Lobophyllia sp.

In conclusion, symbiotic algae tend to be species-specific, whereas bacteria fluctuate significantly over sampling time. Studying the molecular issues of microalgae, the presence, the role of some groups of bacteria involved in the N, C, P, and S cycles, and the influence of environmental parameters should also be encouraged to understand the relationship of coral holobiont better.

Herein, 20 ichnospecies belonging to 8 ichnogenera were identified in bivalves, gastropods, and corals (n = 701) from the Late Pleistocene coral reef along the Red Sea coast, northwest Saudi Arabia. The trace fossils were produced by clionid sponges (47.39%), endolithic bivalves (42.17%), polychaete annelids (5.42%), vermetid gastropods (3.81%), and acrothoracican barnacles (1.21%). The habitat conditions changed gradually, from well-oxygenated, shallow, high-energy back-reef and reef crest bioeroding polychaetes and bivalves, to deep, low-energy reef slope dominated by boring sponges.

Research on the profile of Fe in the seagrass ecosystem has been carried out. Analysis of seawater, sediment, seagrass samples from the association of mangroves, mangroves-coral reefs and coral reefs taken in the waters of Donggala Regency was carried out using the ICP-OES method (Inductively Coupled Plasma-Opticaly Emission Spectrometry).

For a variety of coral species, we have studied the molecular origin of their coloration to assess the contributions of host and symbiont pigments. For the corals Catalaphyllia jardineiand an orange-emitting color morph of Lobophyllia hemprichii, the pigments belong to a particular class of green fluorescent protein-like proteins that change their color from green to red upon irradiation with400 nm light.

The percentage of hard substratum cover will be using the Points Intercept method (Hodgson and Waddell,1996) on the 6 replicate of the transect 150 m total long The data was collected including by hard coral, soft coral (to the specific of genus and living growth of form. For example ACB: Acropora branching coral), dead coral, dead coral with algae, sea weed, sponge, gravel, sand, rock, silt/clay and other organism living in the coral reef. (English et al 1997).

Located in the South-East Asian region, thanks to an over 3400 km of coastline and 3000 islands in the Pacific Ocean, Vietnam is considered as a country has a great potential on marine and coastal economic development. From the North to the South of the country's coastal line, there are hundreds of aquaculture bases, many transshipment ports, fishing ports, tourist beaches, seaside resorts, petroindustrial plants,... that are contributed considerably to the Gross National Product.
