“…Singh et al (2019) for example, reported that studies on seagrasses in the Fiji Islands are very limited, with only one detailed study of biological processes relating to the nutrient dynamics of C and N conducted with Syringodium isoetifolium (Yamamuro et al, 1993). A study by McKenzie and Yoshida (2020) examined seagrass tissue nutrients of Halodule spp. in coastal habitats, indicating an increase in nitrogen availability relative to the rate of leave growth and incorporation of C at the coastal areas.…”

“…However, similar research in the south Pacific region is lacking. In the Fiji Islands, seagrass beds have been identified as an important marine ecosystem (McKenzie and Yoshida, 2020). However, the coastal environments of Fiji are also facing problem of heavy metal pollution (Maata and Singh, 2008).…”

“…Brief descriptions of the morphological characteristics of the Halodule plants are identified based on shape of the leaf tip (trident or rounded) and width of the leaves which is either narrow or wide (Den Hartog, 1970). H. pinifolia is often found in the high intertidal to upper subtidal areas, forming homogeneous patches or intermixes with H. uninervis and H. ovalis (McKenzie and Yoshida, 2020). H. uninervis is found from intertidal to 6 m depth, forming dense or patchy beds as well as intermixes with other species including H. pinifolia, Halophila spp.…”

“…H. uninervis is found from intertidal to 6 m depth, forming dense or patchy beds as well as intermixes with other species including H. pinifolia, Halophila spp. and Syringodium isoetifolium (McKenzie and Yoshida, 2020). Halophila plants are minute and fragile, without stripe-like long leaf blades, but rather oval shaped leaves in pairs and it is the most diverse seagrass group (Kuo, 2020).…”

A unique feature of seagrass among other ecosystem services is to have high phytoremediation potential that is a cost-effective plant-based approach and environmentally friendly solution for metal contamination in coastal areas. The goal of this study was to assess the phytoremediation prospective of seagrass for Cu, Fe, Mn and Zn in Fiji Islands. Heavy metal content was measured in sediments and tissues of the seagrasses Halophila ovalis, Halodule pinifolia and Halodule uninervis to test for local-scale differences. The local study shows that metal concentration in sediment and seagrass tissue was significantly variable, regardless of species and sediment type. Sedimentary concentration of Cu, Fe, Mn and Zn obtained in the present study seemed to be lower than that of previous studies. The results support that H. ovalis is a good bioindicator species since it accumulated up to 5-fold more of these metals compared to the Halodule species.

Kavitha et al.: Phytoconstituents and Antioxidant effect of SeagrassThis research aimed to explore the antioxidant potency of leaf extracts of Syringodium isoetifolium seagrass. In this study, seagrass leaves were collected from the local tribe's source, dried and extracted with water, alcohol, hydro alcohols, acetone and n-hexane. Phytochemical investigation on extracts was performed using chemical and gas chromatography-mass spectrometric techniques. It reveals that the extracts are enriched with pharmacologically active compounds such as phenol, polyphenol, alkaloid, glycoside, saponin, flavonoids, dicarboxylic acids and other constituents. Later, the crude extracts were estimated for antioxidant activity using different in vitro methods such as 2,2-diphenyl-1-picryl-hydrazyl-hydrate, total antioxidant, nitric oxide, superoxide anion and hydroxyl radical scavenging activities. The result demonstrated that the extracts exhibited higher radical scavenging activity as compared to the ascorbic acid. Among the different extracts, the hydroalcoholic extract had shown an excellent antioxidant activity due to the existence of more potent phytochemicals.
