Partial Least Squares Structural Equation Modeling (PLS-SEM) was used to test the hypothesized relationships between sustainability, innovation, and triple bottom line (TBL) outcomes based on survey data from firms operating in the sector. The findings confirm that innovation acts as both a direct outcome of sustainability efforts and a mechanism for mediating its impacts on economic and environmental performance. However, no significant direct or mediating effects were observed for social outcomes, highlighting a persistent gap in this dimension that requires further research. The study contributes to both theory and practice by highlighting the strategic integration of sustainability into organizational innovation processes and its role in enhancing multidimensional performance. By identifying critical pathways and barriers, this study offers valuable guidance for policymakers and industry leaders striving to enhance the long-term sustainability of the Blue Economy.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"183 ","pages":"Article 106902"},"PeriodicalIF":3.7,"publicationDate":"2025-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145049207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In Uruguay, MRF are defined in national legislation but there are no specific regulations, no scientific literature and no formal registry for recreational fishers. Monitoring has mainly focused on freshwater fisheries. This paper presents the first comprehensive study of MRF in Uruguay, analysing data from 88 on-line respondents and 903 fishing events from a pilot monitoring programme. It estimates that there are about 27,636 marine recreational fishers, including 22,571 shore anglers, 4965 boat anglers and 100 spearfishers, who spend about 26 $M annually on fishing gear, boats and related expenses. The study identified 83 species caught, with Whitemouth croaker (<em>Micropogonias furnieri</em>) and stripped weakfish (<em>Cynoscion guatucupa</em>) being the most common. In particular, some threatened species of large coastal sharks were also recorded. Annual catch and expenditures estimations highlight the need for a stable data collection framework for future assessments. Overall, the results improve the understanding of the economic, social and ecological aspects of the MRF, and contribute to its regulation for sustainability.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"183 ","pages":"Article 106899"},"PeriodicalIF":3.7,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145049209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data were collected through workshops (n = 20), focus group discussions, a household survey (n = 120), and key informant interviews. The data were analyzed using content analysis and descriptive statistics. The study revealed high community dependence on mangroves for fishing (42.5 %), farming (36.7 %), and settlements (35 %). Major threats included deforestation (30 % attributed to cutting), pollution, settlement encroachment (35 %), and salt mining (5 % in Kunduchi). Findings showed limited community awareness of mangrove ecological functions, with 95.8 % unaware of carbon sequestration, 77.5 % unaware of sediment dynamics control, and 62.5 % unaware of coastal protection roles. Management challenges included inadequate staffing, insufficient funding, and weak enforcement of conservation regulations. This study concludes that current mangrove management in Dar es Salaam is ineffective due to weak enforcement, inadequate resources, and limited community engagement, leading to ongoing degradation.

It focuses on policy interventions to enhance gender equity and sustainable marine resource management. Grounded in the Gender and Development (GAD) theoretical framework, the research employs a cross-sectional design with quantitative data collected from 94 women seaweed farmers in Paje village, South Unguja region. The findings reveal that access to finance, equipment, and farming experience are statistically significant in influencing participation, while age has a negative effect (p &lt; 0.05). This points to evolving gender dynamics. Contrary to expectations, education level, market information access, and marital status show no statistically significant impact (p &gt; 0.05), suggesting deeper structural barriers. Policy recommendations include gender-sensitive financial inclusion programmes, capacity-building initiatives for young and inexperienced farmers, and institutional reforms to ensure equitable access to aquaculture resources. Likewise, policymakers should address structural barriers, promote inclusive market systems, and challenge restrictive socio-cultural norms to enhance women’s participation. By addressing these challenges, Zanzibar can enhance the inclusiveness of its blue economy policy (2022) and align it with global commitments, particularly SDGs 5 (Gender Equality) and 14 (Life Below Water).

Here, we evaluate the effectiveness of biofouling guidelines in place worldwide, in an Antarctic context, assessing whether a comprehensive international biofouling management agreement could benefit the region. Guided by the International Maritime Organization’s GloFouling Partnership's guidelines and building on recent work within the Antarctic Treaty System, we review the risks posed by biofouling, examine the applicability of existing management strategies, and identify technical elements for a comprehensive biofouling agreement tailored to Antarctica. The implementation of risk-based biofouling policies, through the Antarctic Treaty System in the departure ports of Antarctic vessels is proposed. Given the increasing vessel activity in the Antarctic and rapidly changing environmental conditions as a result of climate change, implementing specific biofouling regulations will further enable the Antarctic Treaty System’s stakeholders to discharge their obligations to protect Antarctica’s unique marine ecosystems and biodiversity.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"183 ","pages":"Article 106896"},"PeriodicalIF":3.7,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145027175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We undertake a rigorous multidisciplinary review of economic, environmental, and legal literature to identify and critically assess the key factors influencing States’ strategies during these complex negotiations. By analyzing each domain, we clarify how competing economic imperatives, evolving scientific evidence on biodiversity and carbon cycle disruption, and shifting legal norms independently inform the negotiation process and its implications for the Mining Code’s substantive content and governance mechanisms. Drawing on recent jurisprudence from the International Tribunal for the Law of the Sea, which elucidates the relationship between UNCLOS and international climate frameworks under the United Nations Framework Convention on Climate Change and Paris Agreement, we highlight the increasing prominence of environmental protection within States’ legal duties. We argue that this evolving legal context supports the prioritization of precautionary and protective measures in the Mining Code and encourages cautious approaches that address scientific uncertainty and climate-related risks.

Within this implementation of the ecosystem approach, the health and status of the marine ecosystem is required to be regularly reviewed by Strategic Ecosystem Assessments (SEcAs). These are supported by strategic regional-scale ecosystem monitoring. SEcAs track progress towards Good Environmental Status (GES) and identify principal concerns related to specific ecosystem elements. At the same time, other regional and national legislative frameworks aimed at protecting the marine environment require three additional forms of ecosystem assessment. Public plans and policies that may result in human activities which impact the ecosystem are required to have Strategic Environmental Assessments (SEAs) in order to identify any potential impacts of such plans. These are often on a regional scale. At a smaller spatial scale, individual developments, such as offshore wind farms, need Environmental Impact Assessments (EIAs) and Cumulative Impact Assessments (CIAs) before they are granted a consent and/or licence to progress by the relevant competent authority. Licensing frameworks generally require related targeted monitoring at the scale of individual developments. Using the Scottish region of the North Sea as a case study, this paper considers how monitoring and assessment under these four processes (SEcAs, SEAs, EIAs and CIAs) interface.

This study evaluates the impact of ITQs on bluefin tuna (Thunnus thynnus) in the Ports of the Strait of Gibraltar, where ITQs have been applied since 2008. To analyze these effects, we use Lorenz curves and Gini indices to examine the evolution of catches and income. The results reveal that the application of ITQs has reinforced the concentration of economic activity in these ports. Based on these findings, we propose a new ITQ distribution to ensure the economic viability of small-scale vessels and to address the concentration caused by the current ITQ system. Our redistribution proposal focuses on reallocating quotas to vessels that no longer catch bluefin tuna as bycatch and those that currently have low allocations.

However, management effectiveness continues to face challenges, partly due to limited staff capacity. This study presents the first evaluation of staff capacity in Indonesian MPAs, examining organizational structures, role clarity, required competencies, and staffing adequacy across 36 priority MPAs. Using document reviews, questionnaires, and focus group discussions, we found overlapping roles, broad job descriptions, and a mismatch between existing competencies and operational needs. Over two-thirds of the MPAs fell below the baseline of eight staff, and only three MPAs met the recommended staffing level of twenty staff to allow effective operations. Surprisingly, staff numbers were not correlated with MPA size and ecological characteristics (coverage of coral, seagrass, and mangrove), though they were positively associated with cumulative human pressure. Our analysis identified 20 role-specific competencies, four of which are not covered by the national certification scheme. Recognizing that each MPA has unique ecological characteristics, socioeconomic contexts, and management complexities makes staffing targets difficult to apply uniformly. Nevertheless, our proposed benchmarks offer a pragmatic reference to support planning and resource allocation when adapted to site-specific needs. Our results underscore the need for a structured, competency-based staffing strategy tailored to local contexts. We recommend establishing clear roles and job descriptions, aligning competencies with management needs, while also fostering partnerships with NGOs and local governments.
