This diversity and variability extends into associated trade and distribution systems that move fish from relatively few landing sites to broad consumer bases in rural and urban areas. However, little is known about the domestic trade of fish at a national scale, as fish move through connected informal economies that are made up of networks of community and market actors. To help address this gap, this study maps the structure and function of the market systems that coastal fisheries in Vanuatu feed into, and does so by characterizing dimensions of supply, trade and distribution dynamics, and market organization. A framework for mapping fish trade networks is proposed and applied to understand dynamics and variability in the way fish transit. The study sheds light on key areas including the spatial and temporal variation in the distribution of different types of fish, and the considerable dynamism of the fish market system in relation to disruptions. Harnessing domestic trade stands to improve sustainable management, considering its driving role behind fishing as well as people’s access to fish. A baseline understanding of trade and distribution can critically support fisheries management authorities to achieve their ambitions to more effectively respond to challenges in improving production, fish storage, and connectivity between fishers and consumers.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"188 ","pages":"Article 107092"},"PeriodicalIF":3.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385694","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}

The results reveal significant spatial variation in ocean health scores, which appear to reflect socio-economic, ecological, and geographical differences across municipalities. Municipalities perform well in goals related to coastal protection and carbon sequestration, while challenges persist in fishing opportunities and natural products extraction. This study also introduces a new goal for artisanal fishing equality, addressing the socio-economic barriers that limit access to fishing resources in Chile. The study discusses how existing management strategies can be adjusted to tackle specific challenges faced by municipalities, particularly in areas with low scores.

While data underpins much of the implementation of the BBNJ Agreement and provisions related to all four package elements, the Agreement itself will also shape how data is governed, particularly through the Clearing-House Mechanism (ClHM), its data infrastructure. This article analyses the implications of the BBNJ process for data governance in ABNJ by looking into the discussions on ‘data’ within the negotiation room, particularly those on the design of the ClHM. To conceptualize this process, we introduce the concept of ‘data rationales’ describing the expectations, understandings and interests expressed by different actors in relation to data. These data rationales are validated, reinforced, and reproduced through the making of the ClHM, the data infrastructure of BBNJ that shapes the overarching data rationality for data governance in ABNJ. Drawing on observation data from the BBNJ negotiations, we identified 835 observations where ‘data’ was referenced. Through an iterative and inductive coding process, these observations were categorized into ten ‘BBNJ Data Rationales’. We further analyzed how these rationales interact in discussions on the design of ClHM and identified twelve key questions to inform the ongoing negotiations. We argue that the BBNJ process provides a unique opportunity to shape more equitable data governance in ABNJ by enabling actors to articulate and negotiate their priorities among competing data rationales in the design of the ClHM.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"188 ","pages":"Article 107079"},"PeriodicalIF":3.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385691","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}

While Tasmania produces relatively small volumes, the industry is the most valuable seafood sector in Australia. Nevertheless, the industry faces significant challenges and has become subject to increasing public and governmental scrutiny. Over the years, this resulted in the introduction of dedicated regulatory frameworks governing aquaculture operations but with limited inclusion of fish welfare beyond the existing animal welfare legislation. Farmed fish welfare has rapidly become a major concern for the public and plays a major role in the social acceptance of the salmonid industry. The regulators have therefore been urged to either address gaps in or further enhance the frameworks governing fish welfare with direct application to farmed salmonids. The introduction and adoption of a dedicated fish welfare regulatory framework is inconsistent globally. While some countries have placed greater focus on fish welfare and introduced either government-led or -supported frameworks, others have prioritised industry-led arrangements which are not enforceable. This review aimed at identifying the existing legislation, regulations, and other arrangements that underpin salmonid welfare management in Tasmania and comparing those with relevant international counterparts. Overall, when it comes to salmonid aquaculture regulations, Tasmania is yet to achieve the same level of comprehensiveness seen in other major producing countries, but it is also well-positioned to make rapid improvements. The industry would benefit from further augmentation of the existing fish welfare regulatory framework which would lead to improved welfare outcomes and public perception.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"188 ","pages":"Article 107086"},"PeriodicalIF":3.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385690","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}

Fish escapes generate economic inefficiencies due to their effects on the marine environment (environmental externalities) and their potential impact on wild fish markets (imperfect information). In Spain, there is no specific legislation defining escaped fish and there are no specific measures to detect and/or inform consumers about the risk of purchasing escaped fish. This paper aims to evaluate the magnitude of these undesired effects by assessing whether consumers of farmed fish are willing to bear the costs associated with the market failures caused by fish escapes. For this purpose, we designed a discrete choice experiment that was administered to a representative sample of fish consumers in Spain. Our results indicate that respondents value aquaculture positively, primarily due to its role in providing fresh fish at competitive prices. Although respondents expressed some concerns about environmental externalities, they support the development of aquaculture. Using a mixed logit model, we estimated that the net benefit of preventing fish escapes ranges between €1.23 and €8.96 per kilogram of farmed fish, depending on the number of measures applied. These estimates reflect the social value attributed to both the environmental externalities and the imperfect information in fish markets resulting from fish escapes, ranging from 2 to 14.3 million euros in aggregate terms. These figures are useful to conduct cost-benefit analyses of escape management measures at public and private levels.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"188 ","pages":"Article 107082"},"PeriodicalIF":3.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385693","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 this study, we provide a quantitative, systematic approach to refine existing EBSAs within the Western Mediterranean Sea via spatially explicit proxies for the internationally agreed protection criteria. Spatial prioritization was conducted and included environmental stability to account for ecological resilience under climate change. Our results reveal a pronounced spatial imbalance in the representation of EBSA criteria within internationally agreed protection schemes (Natura2000 sites, Ramsar sites, Specially Protected Areas of Mediterranean Importance and proposed Sites of Community Importance), ranging from 2.2 % to 63.9 %, providing relevant information for the study area. There is a marked bias toward the northern part of the basin, with current EBSAs covering 47 % of the study area, while existing protected spatial features correspond to 19.7 % of the study area. This spatial bias may undermine the effectiveness of marine biodiversity conservation and highlights the need for more equitable and data-driven spatial planning approaches.

However, its ambiguous wording may lead to interpretive divergences and potential conflicts. With the Agreement now in force, the practical effect of this clause no longer depends solely on the text itself; rather, subject to the rules of treaty interpretation, it will be jointly shaped by the strategic interactions among the Conference of the Parties, potential parties, and dispute settlement bodies within an institutional framework. To anticipate its implementation pathway, this paper develops a tripartite game model, analyzing the distinct strategic choices and equilibrium outcomes of the above three actors in interpreting the \"not undermine\" clause. The findings are as follows: (1) phased implementation is an important pathway for optimizing the clause’s effectiveness. In the early stage following entry into force, cautious application and transitional arrangements can facilitate broad participation; once membership size and institutional authority stabilize, the operational content of the clause can be progressively elaborated through subsequent practice, technical guidance, and coordination mechanisms. (2) The leading role of key countries carries greater weight than merely increasing the number of state parties. By leveraging their inherent strengths to exercise differentiated leadership, key countries can effectively amplify the Agreement’s influence. (3) Where multiple plausible interpretive approaches exist, the institutional costs faced by dispute settlement bodies affect the degree to which different interpretive orientations are acceptable. While the analysis primarily serves the implementation of the BBNJ Agreement, the framework’s insights into multi-actor interaction, interpretive flexibility, and institutional coordination also offer methodological reference for other ocean conservation regimes that contain similar “not undermine” clauses.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"188 ","pages":"Article 107090"},"PeriodicalIF":3.7,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147385695","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}
