“…Several studies have successfully used d 18 O otolith as a proxy of salinity or temperature to retrospectively identify habitat use in coastal fishes (Elsdon and Gillanders 2002;Kerr et al 2007;McMahon et al 2011;Shirai et al 2018), because lower d 18 O otolith values indicate high temperatures and low salinity, and vice versa (Campana 1999;Weidman and Millner 2000;Kitagawa et al 2013;Shirai et al 2018). However, in the tropical zone, particularly the ECPM, seawater temperatures often vary narrowly (1-38C) on the surface and in the water column throughout the seasons (Akhir 2012;Akhir et al 2014;Daryabor et al 2015). Given that water temperatures in rivers could also be affected by rainfall in the NEM season and upstream water input, annual mean temperature nevertheless varied within 38C in the study area (Suratman et al 2015).…”

“…During the NEM, surface current eddies advect water southward from coastal Vietnam, there being an absence of coastal upwelling. Temperature and salinity in the study area ranged from 29.2 to 30.98C and from 31.5 to 31.8 PSU (Akhir et al 2014;Daryabor et al 2015). Unlike the two main monsoon seasons, slow currents are usually observed during the short inter-monsoon periods (Akhir et al 2014;Daryabor et al 2015;Kok et al 2015).…”

“…Sea circulation, driven by monsoon wind seasons, affects the reef environments along the coast. During the SWM, coastal currents flow northward along the ECPM and advect water masses from the Java Sea (Qu et al 2005), in association with strong upwelling from Kuantan coast, bringing cool salty water along the coast (Daryabor et al 2015;Kok et al 2015). Accordingly, sea surface temperatures and salinity along the Terengganu coast range from 28.6 to 29.08C and from 32.1 to 32.6.6 practical salinity units (PSU; Akhir et al 2014).…”

Stable isotope analyses of muscle tissue (δ13Cmuscle and δ15Nmuscle) and otoliths (δ13Cotolith and δ18Ootolith) were used to retrospectively track habitat uses of Lethrinus lentjan, and to determine any association between Setiu Lagoon (nursery habitat) and coastal artificial reefs (CARs; adult habitats) on the Terengganu coast, Malaysia. Muscle stable isotopes exhibited a spatial change from inshore to offshore habitats associated with growth, possibly related to the reef-ward movement of the fish. Otolith stable isotopes of adult fish from CARs were measured in juvenile (from outside the core to the first opaque zone of otolith) and adult (the edge of otolith) portions and were compared with those of juveniles from Setiu Lagoon, suggesting that the adult fish may not primarily use the lagoon as a nursery before ontogenetically migrating to CARs. The effects of coastal currents between monsoonal seasons could reorientate offshore juvenile migration; hence, adult cohorts in CARs may be replenished from various nursery habitats along the coast. Additionally, similarities in the δ18Ootolith values of juvenile and adult sections suggested that some individuals may not spend their juvenile phases in shallow estuarine habitats. Based on the findings of this study, we recommend that coastal conservation strategies take into account multiple nursery habitats rather than a single one.

“…The southern region of the South China Sea (SSCS) has complex bathymetry and water circulation near the equator in which the monsoon plays a dominant role (Daryabor et al, 2010(Daryabor et al, , 2014(Daryabor et al, , 2015. The SSCS connects to the Java Sea, which is a source of low-salinity water mass (Wyrtki, 1961) through the Sunda Shelf and Karimata Strait, as well as the Andaman Sea through the Strait of Malacca (Fig.…”

“…The SSCS receives heat mostly from the sun and the atmosphere, as well as freshwater from precipitation, which can significantly affect the climate system of the region (Gong and Wang, 1999;Zhang et al, 2003). The Asian-Australian monsoon system largely influences the general current circulation in the South China Sea (SCS), particularly in the southern region (Wyrtki, 1961;Chu et al, 1999;Daryabor et al, 2015) and hence regulates various transports across the Sunda Shelf/Karimata Strait and Strait of Malacca. A better estimation of transports across the SSCS is important for understanding inter-ocean exchanges, particularly between the Indian and Pacific Oceans.…”

Abstract. Using the Regional Ocean Modeling System (ROMS), this study aims to provide an estimate of the volume, freshwater, heat, and salt transports through the Sunda Shelf and the Strait of Malacca in the southern region of the South China Sea (SSCS). The modeling system is configured with two one-way nested domains representing parent and child with resolutions of 1/2 and 1/12°, respectively. The simulated currents, sea surface salinity, temperature and various transports (e.g., volume, heat, etc) agree well with the observed values as well as those estimated from the Simple Ocean Data Assimilation (SODA) re-analysis product. The ROMS estimated seasonal and mean annual transports are in accord with those calculated from SODA and those of limited observations. The ROMS estimates of mean annual volume, freshwater, heat and salt transports through the Sunda Shelf into the Java Sea are 0.32Sv (1 Sv = 106 m3 s−1), 0.023 Sv, 0.032 PW (1 PW = 1015 j s−1), and 0.010 × 109 kg s−1 respectively. The corresponding ROMS estimates for mean annual transports through the Strait of Malacca into Andaman Sea are 0.14, 0.009 Sv, 0.014 PW, and 0.0043 × 109 kg s−1 respectively. The relative percentages of mean annual transports computed individually from those of volume, heat, salinity, and freshwater between the Strait of Malacca and the Sunda Shelf range from 39 to 43.8%. This reflects that the Strait of Malacca plays an equally significant role in the annual transports from the SSCS into the Andaman Sea.
