Using China's summer fishing moratoria and the COVID-19 lockdown as quasi-natural experiments, we aimed to investigate whether temporal reductions in fishing activity affect the occurrence of whale sharks (<em>Rhincodon typus</em>) in Chinese coastal seas. We compiled occurrence records from social media platforms (2016–2023), standardized them by fishing effort data derived from Global Fishing Watch, and validated findings through interviews with local fishers. Our analysis revealed that both the summer moratoria and the COVID-19 lockdown significantly reduced fishing intensity, with moratoria having a stronger effect. Standardized whale shark occurrences increased significantly during summer moratoria, suggesting behavioral return to coastal foraging grounds in response to predictable, high-magnitude reductions in human disturbance. However, no comparable effect was detected during the COVID-19 lockdown. These findings highlight the role of disturbance magnitude and temporal predictability in shaping marine megafauna behavior. Additionally, the occurrences from social media also renewed the IUCN range map and suggested some foraging sites of whale sharks in China's seas. We recommend targeted protection at seasonal foraging sites during summer moratoria and adaptive spatial management to mitigate bycatch risks in China's seas. Our study highlights the utility of integrating social-media sightings and local ecological knowledge to assess the behavioral response of marine megafauna to policy interventions, and to monitor spatio-temporal dynamics of rare and iconic marine megafauna at large spatial extents.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"270 ","pages":"Article 107856"},"PeriodicalIF":4.8,"publicationDate":"2025-07-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144670852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This study aims to unravel the underlying mechanisms and implementation pathways for sustainable mangrove management through a qualitative case study in Quanzhou Bay, China. Data were collected through literature and policy reviews, alongside semi-structured interviews with 14 stakeholders, and were analyzed using an adapted Social-Ecological System (SES) analysis framework focused on three core subsystems—Environmental Commons, Governance System, and Action Groups. Our findings reveal that sustainable mangrove management depends not only on ecological conditions and institutional design, but also on inclusive, adaptive governance and meaningful stakeholder participation. Notably, effective governance models facilitate the delivery of multifunctional ecosystem services by mangroves, including ecological, social-cultural, and intrinsic values. Furthermore, the collective participation of stakeholder—fostered through contracts, collaboration, and consensus-building—is crucial for promoting sustainable mangrove governance. This evidence-based understanding of how social-ecological factors, ecosystem services delivery, and stakeholder engagement can inform the development of tailored management strategies in other mangrove regions worldwide, supporting the restoration goals of the UN Decade of Ecosystem Restoration and the Post-2020 Global Biodiversity Framework.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107860"},"PeriodicalIF":4.8,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144665855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

This study integrates multiple datasets to assess trade-offs in ecosystem services of a Ramsar wetland due to its conversion into aquaculture ponds in the coastal region of Indian peninsula. Local perceptions of ecosystem services and attitudes toward the Kolleru wetland were gathered using a standardized questionnaire, while land system changes from 1975 to 2023 were analyzed using Landsat imagery. The findings indicate that Kolleru wetland provides numerous ecosystem services ranging from local to global significance. The wetland functions as a vital habitat for migratory waterfowl including threatened species and serves as a natural buffer against floods and storm surges in the coastal area. Socioeconomic assessments revealed that the Kolleru wetland supports livelihoods by supplying fish, food, fodder, and medicinal plants. Chi-square (χ²) analysis showed that perceptions and attitudes are strongly influenced by educational background and patterns of resource use (χ² = 4614.3, <em>p</em> =&lt; 2.2^e−16). The respondents perceived greater monetary benefits to fishponds (11488.5 million USD/yr) and paddy fields (0.58 million USD/yr) compared to the natural wetland. Nevertheless, the intact wetland delivers a variety of provisioning, regulating, supporting, and cultural services. Land use land cover analysis revealed a dramatic shift, with aquaculture expanding from 10% of the wetland area in 1990 to 57% in 2023. This transformation has led to significant trade-offs in ecosystem services, including habitat loss for migratory birds, disruption of water flow, and reduced flood storage capacity. The study emphasizes the need for effective management strategies that balance wetland conservation with the socioeconomic needs of local communities.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107861"},"PeriodicalIF":4.8,"publicationDate":"2025-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144662075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Currently, offshore wind farm siting in China is largely guided by policy priorities, often with insufficient integration of wind energy resource assessments and socio-ecological considerations. This may result in diminished project efficiency and elevated ecological and environmental costs. This study proposed a methodology that combined multisource heterogeneous data, enabling coupling of wind, ecological, and economic datasets. Using the Delphi method (Delphi) and Geographic Information System (GIS), scenarios were developed based on wind energy effects, ecological impacts, and economic costs. The results showed that ERA5 data was highly consistent with the regional wind energy performance. In the wind energy scenario, the high suitability sites were mainly located 50–75 km offshore in northern Fujian and southern Zhejiang, with an area of 142,114 km². In the ecological scenario, the medium suitability sites were located at least 110 km offshore, and the high suitability sites were at least 260 km offshore. Although the ecological disturbance decreases with increasing offshore distance, the economic cost increases. In the economic scenario, the high suitability sites were located within 90–150 km offshore and covered an area of 150,769 km². The total area of optimized high suitability sea area for wind farms was finally identified as 179,904 km² through the weighting of the scenario indicators, of which 6106.83 km² was located in the northern part of Fujian, 95 km offshore, and the rest of it was distributed in the sea area beyond 250 km offshore. In addition, current wind farms were mainly located in areas of low and medium suitability, emphasizing the potential for future wind power development in areas of high suitability. This novel approach provides a practical tool for optimizing offshore wind farm siting in China and offers a transferable framework applicable to other countries and regions with available multisource data, supporting more balanced and sustainable offshore wind development.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107854"},"PeriodicalIF":4.8,"publicationDate":"2025-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144654921","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Here we assess the potential interaction between shorebirds and terrestrial coastal aquaculture (present and future) in Queensland, Australia. Queensland has a growing aquaculture industry, focusing on high-value coastal species such as tiger prawns. We found high potential for interaction between active aquaculture sites and shorebirds, with 14.5% of active sites directly overlapping Shorebird Areas (mapped shorebird habitat) and 50% within 5 km. Active aquaculture sites near Pumicestone Passage and Burnett River Estuary Shorebird Areas require special management consideration due to the high counts of shorebirds at these sites (many at internationally and nationally significant levels) and their close proximity to active aquaculture sites. In addition, we found that a satellite tracked critically endangered Far Eastern Curlew likely visited an active aquaculture site, underscoring the need for further on-the-ground assessment and effective management. Nearly all (7 of 8) aquaculture development areas identified for future aquaculture expansion overlapped or were within 5 km of a Shorebird Area, along with 15% of inactive sites (approved sites without ponds), signifying the need to plan and manage development of future aquaculture sites carefully.

In this study, we developed a comprehensive estimation framework for carbon sinks associated with marine shellfish aquaculture, algal aquaculture, and capture fisheries. We also conducted a thorough assessment of marine fishery carbon sinks in China's coastal provinces from 2008 to 2022. Additionally, the spatiotemporal differentiation of China's marine fishery carbon sink was analyzed using the Dagum Gini coefficient and β-convergence model. The results indicate that China's marine fishery carbon sink has exhibited a slight downward trend, decreasing from 13.97 million tons in 2008 to 11.64 million tons in 2022. The distribution of the marine fishery carbon sink across China's coastal provinces is spatially uneven, with higher levels observed in eastern and southern coastal provinces and lower levels in northern coastal provinces. China's marine fishery carbon sinks exhibit a β-convergence characteristic and a catch-up trend in which regions with lower carbon sink levels experience faster growth. To further enhance the marine fishery carbon sink, it will be essential to implement additional protection and restoration projects, optimize regional development strategies for marine fishery carbon sinks, and establish incentive mechanisms to accelerate the improvement of these carbon sinks.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"269 ","pages":"Article 107846"},"PeriodicalIF":4.8,"publicationDate":"2025-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144654918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
