Seagrass beds and their associate biota are very important in maintaining the balance of coastal ecosystems. Samuh Beach is one of seagrass ecosystem area in Bali Island. One of the biota that exists in the seagrass ecosystem in Samuh Beach is Echinodermata. Since the limited information and the complex activities at Samuh Beach make research about associations of Echinodermata with seagrass, this research seems become important to be conducted. This study was aimed to determine the density of species, species composition, and distribution patterns of lamun and Echinodermata in the coastal waters of Samuh beach. Data analysis was performed by using density type, species composition, dispersion index of morisita and association. The average seagrass density of each station in Samuh coastal waters ranged from 156-246 stands/m2 and the highest density of Echinoderms is Diadema setosum in each station. The species composition of seagrass in Samuh beach comprises five species of seagrass namely: Enhalus acoroides, Halophila ovalis, Thalassodendron ciliatum, Cymodocea serrulata and Syringodium isoetifolium. The composition of Echinodermata species that found amounted to 13 species of Echinodermata namely: Diadema setosum, Amphiura sp., Archaster typicus, Asterias sp., Mespilia globulus, Tripneustes gratilla, Pseudoboletia maculata, Protoreaster nodusus, Ophiactis resillens, Ophiopteris antipodum, Centrostephanus rodgersii, Echinothrix and Echinothrix mathei. Based on the calculation of morisita, seagrass and Echinodermata Index in Samuh Beach was spread uniformly and clumped. The result of association analysis showed that there were positive association, negative association and association with no relation between seagrass and Echinodermata in Samuh Beach.

Marine Environmental Pollution

The northeastern coastal waters of Vietnam contains diverse and abundant prawns with economic importance. In recent years, overexploitation and marine environmental pollution have led to the decrease of prawns. The purpose of this study is to identify the current diversity and distribution of prawns in this region. Prawns were sampled by a trawl net at four sites in 2011. A total of 21 species of three families of the superfamily Penaeoidea was distributed in this area. The family Penaeidae is the most diverse with 19 species, while each of family Sicyoniidae and Solenoceridae has only one species.

Water samples collected by R/V DR. FRIDTJOF NANSEN during Myanmar ecosystem survey 2018 were analyzed to determine the species composition and distribution of phytoplankton. A total of one hundred and eighty-eight taxa of marine phytoplankton were identified and comprised of 116 taxa of diatoms, 67 taxa of dinoflagellates, 2 taxa of silicoflagellates and 3 taxa of cyanobacteria. Phytoplankton community was dominated by diatoms with 61.7% of total samples, followed by 35.6% of dinoflagellates. Species composition and abundance was found to be highest at station 799 with 90 species (2147no/m3) and lowest at station 846 with 36 species (673no/m3). The index values encountered from Taninthayi coastal waters ranged between 3.97 and 3.31 for species diversity index (H’), between 0.94 and 0.05 for evenness index (E’) and between 13.76 and 6.69 for species richness index (D’). High diversity index values (H’, E’, and D’) were recorded at the nearshore stations. The density and diversity of phytoplankton were positively correlated with the nutrients (chlorophyll a, nitrate, nitrite, silicate, phosphate) and negatively correlated with the temperature and salinity.

This paper exhibites species composition and distribution of marine seaweed at 10 sites of Co To and Thanh Lan islands in May 2019. The studies record 76 species of marine algae in the area, belonging to four divisions: Cyanophytes, Rhodophytes, Ochrophytes and Chlorophytes. Among them, five species are classified into Cyanophytes (comprising 6.6% of total species); thirty-four species into Rhodophytes (44.7%); twenty-one species into Ochrophytes/Phaeophytes (27.6%) and sixteen species into Chlorophytes (21.1%). The species composition of marine seaweeds in Co To and Thanh Lan shows significant differences as follows: 22 species (sites number 4 and 10) to 58 species (site number 2) and the average value is 38.7 species per site. Sørensen similarity coefficient fluctuates from 0.33 (sites number 5 and 10) to 0.84 (sites number 1 and 3) and the average value is 0.53. The current investigations show that four species of twenty-one species are collected in the littoral zone and forty-two species in the sub-littoral zone (in which there are thirteen species distributed in both littoral zone and sub-littoral zone). The algal flora in Co To and Thanh Lan is characterized by subtropics.
