A total of 30 individuals were collected monthly from November 2024 to October 2025 and examined for reproductive characteristics. Five gonadal maturity stages were identified, consistent with reproductive patterns typical of tropical bivalves. The population exhibited a significantly male-biased sex structure, with 55.5% males, 30.0% females, 10.3% hermaphrodites, and 4.1% indeterminate individuals, resulting in a sex ratio of 1.9:1. The gonadosomatic index showed clear seasonality, with peak spawning activity occurring from March to May and a secondary spawning period from July to October. The size at first sexual maturity (L50) was estimated at 50.9 mm shell height, and individuals began reproducing at approximately 46 mm. Absolute fecundity increased with size, averaging 854,540 ± 322,468 eggs per individual, while relative fecundity averaged 8540 ± 2358 eggs per gram of body weight. These findings indicate that <em>S. sinensis</em> exhibits an extended spawning season, high fecundity, and size-dependent reproductive characteristics. Establishing harvest size limits above 56 mm and regulating wild collection are recommended to ensure population sustainability. Overall, the study provides foundational reproductive data essential for effective resource management and for supporting future hatchery development of <em>S. sinensis</em> in Vietnam.</div></div>","PeriodicalId":21070,"journal":{"name":"Regional Studies in Marine Science","volume":"101 ","pages":"Article 105291"},"PeriodicalIF":2.7,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148638291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Monthly beach profiles and sediment samples were analysed to measure grain size parameters (Mean, Skewness, Kurtosis and Sorting), and volumetric variations. Results indicate a repetitive pre-monsoon accretion and textural fining seasonal cycle, preceded by massive monsoonal erosion (in excess of 70% volume loss at certain locations) and coarsening, followed by post-monsoon recovery with volumetric restoration but worse sorting. Site-specific trends emphasize local geomorphic control, Utorda recorded repetitive and stable textural reorganization, Benaulim recorded robust volumetric recovery but chronic post-monsoon instability, whereas Cavelossim reflected anomalous monsoon sorting attributed to longshore transport.

The Digital Elevation Models derived from repeated surveys reveal the development of a persistent submerged sandbar that forms an ebb-delta system, in which wave-driven processes largely exceed tidal forcing, promoting predominantly alongshore sediment bypassing. Sediment budgets computed at multiple temporal scales show a marked seasonal contrast. During summer periods, morphological changes are limited and sediment variability is largely controlled by dredging operations. In contrast, winter conditions are dominated by storm-driven sediment fluxes, with individual storm events mobilizing several hundred thousand cubic meters of sediment, frequently exceeding annual dredging volumes. For example, the winter of 2010/2011 recorded a net accretion of + 287,329 m³ despite seven storm events, while the February 2017 storm event (PSI ≈ 7222 m²·h) mobilized over 100,000 m³ within a two-week period. These events drive rapid reorganization of the ebb shoal, channel infilling, and updrift beach progradation, periodically compromising navigation depth within the inlet channel. Despite repeated dredging interventions (annual volumes consistently exceeding 100,000 m³ and reaching up to 400,000 m³ in recent years), the submerged sandbar consistently re-establishes at depths of approximately −5 to −6 m, indicating a strong tendency toward a storm-controlled dynamic equilibrium. The long-term natural infilling rate of approximately 1000 m³ day⁻¹ , derived from 14 years of sediment budget analysis, underscores the system's high resilience to anthropogenic interventions. The results demonstrate that storm-driven sediment dynamics impose fundamental constraints on dredging efficiency and channel maintenance strategies, highlighting the need to explicitly account for extreme wave conditions in the engineering management of wave-dominated inlet channels.</div></div>","PeriodicalId":21070,"journal":{"name":"Regional Studies in Marine Science","volume":"101 ","pages":"Article 105309"},"PeriodicalIF":2.7,"publicationDate":"2026-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148738874","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mann–Kendall tests revealed significant decreasing trends in annual mean salinity, annual maximum salinity, and exceedance months for 20‰ (E20) and 25‰ (E25), whereas annual rainfall showed no significant trend. Spearman correlation analysis indicated strong positive associations between salinity levels and exceedance months (r = 0.88–0.93, p &lt; 0.001), whereas annual rainfall showed no statistically significant association at the annual aggregation scale. Partial correlation analysis controlling for rainfall confirmed that the salinity–exceedance linkage remained robust, indicating that annual rainfall alone did not explain the observed salinity–exceedance association, although unmeasured hydrological and operational influences could not be excluded. Poisson generalized linear models further demonstrated that annual mean salinity was significantly and positively associated with the expected number of exceedance months for both E20 and E25 (p &lt; 0.001), whereas annual rainfall was not statistically significant. Incidence rate ratios indicated that a 1‰ increase in annual mean salinity was associated with approximately 12% and 19% higher expected numbers of E20 and E25 exceedance months, respectively. Model diagnostics indicated no overdispersion and high in-sample goodness-of-fit, although the latter partly reflects the structural relationship between annual mean salinity and threshold exceedance months. These findings indicate that the observed salinity–exceedance association was not explained by annual rainfall in the fitted models, although event-scale rainfall effects could not be evaluated using monthly mean salinity data.

Although the root mean square difference between the daily OISST and buoy observations in SIS was approximately 1 °C, nearly half of discrepancy (about 0.48 °C) can be attributed to sub-grid spatial variability arising from the mismatch between OISST grid size and coastal temperature gradients. Consequently, the uncertainty of OISSST dataset is likely smaller than is likely smaller than the 1.1 °C anomaly threshold used for MHW detection. In the SIS, MHWs occurred only sporadically until the 2010s, whereas prolonged MHW events developed during 2024–2025. Sea surface temperatures broadly fluctuated in accordance with the Pacific Decadal Oscillation, with additional contributions from local short-wave radiation and temperature history.

To the best of the authors’ knowledge, the UNESCO-IOC step-by-step framework has not previously been applied to a structured readiness assessment of MSP development in Bangladesh. We go beyond readiness assessment to classify institutional and structural barriers, analyze functional compatibility-conflict among maritime uses and propose governance pathways explicitly grounded in those barriers rather than in idealized planning models. A qualitative narrative review of 121 secondary sources from 1908 to 2026, including legislation, policy instruments, institutional reports and academic literature was conducted. Findings show that Bangladesh’s MSP progress is largely stalled in the early preparatory phases, with only fragmentary or partial achievement across Steps 1–6 and no documented advancement in Steps 7–10. The principal barriers are governance fragmentation, the absence of a formally mandated lead agency, weak inter-ministerial coordination, limited financial commitment and underdeveloped geospatial infrastructure. The compatibility-conflict analysis highlights growing pressures between industrial uses and ecologically sensitive areas. Governance pathways are proposed across four interconnected domains - legal and policy, institutional and coordination, socio-ecological and climate and technical and scientific governance.
