As the continuous expansion of the global marine product trade, corresponding trade networks are becoming increasingly complex. An in-depth analysis of its intricate trade network becomes crucial. To this end, this paper utilizes global trade data during 2000–2022 to construct a weighted directed complex network, employing complex network analysis to examine its spatiotemporal evolution. Additionally, a geographically weighted regression model is employed to systematically analyze the factors influencing the global marine product trade network, and uncover its internal evolutionary mechanisms. The results indicate: 1) the number of nations engaged in global marine product trade has steadily increased, with import ones often outpacing export ones, signifying a seller-dominated market; 2) the trade partners for each nation have remained stable, but there has been a notable increase in export partners since 2015; 3) the USA, Spain, and Thailand maintain their leadership, with Japan diminishing and China rapidly ascending; 4) the influence of per capita GDP and population size is shaped by global economic stability and major events; 5) economic and population factors affect marine product trade with notable regional and temporal variation. These findings may help nations in crafting reasoned marine product trade policies, fostering international cooperation and sustainable development in marine fisheries.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"177 ","pages":"Article 106681"},"PeriodicalIF":3.5,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143641753","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}

This research builds a comprehensive carbon emissions inventory for marine fisheries, accounting for both carbon sources and sinks, and examines the relationship between carbon emissions and economic growth in the marine fisheries sector across 11 coastal provinces of China. The study found that carbon emissions from marine fisheries in these provinces increased initially and then decreased between 2007 and 2022. Emissions displayed a low level of spatial clustering, exhibiting a relatively scattered distribution pattern. The decoupling of carbon emissions from economic growth in China's coastal marine fisheries is primarily characterized by weak decoupling (WD) and strong decoupling (SD). This decoupling is largely driven by factors such as energy intensity and industry size. Energy intensity and the size of the employed labor force exert a negative cumulative driving effect, while industrial scale has a positive cumulative driving effect. The government and relevant fishery departments should prioritize key fishery production areas, promote energy-saving upgrades for fishery facilities and fishing boat equipment, and vigorously develop low-carbon aquaculture to fulfill China’s “dual carbon” targets. The scientific research value of this paper enhances the analysis of the traditional decoupling index, constructing a relatively new analytical framework for exploring the relationship between the development of the marine fishery economy and the decoupling of carbon emissions.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"177 ","pages":"Article 106671"},"PeriodicalIF":3.5,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143591349","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}

However, few studies investigate whether the effectiveness of such a punishment option varies with community network structures. To examine this aspect, we targeted 10 Japanese fishing communities and conducted public goods games. During the course of the experiments, we exogenously changed the rule of the game and introduced pun- ishment opportunities. Adopting the difference-in-differences strategy, we compare individual contributions between closed and open community structures before and after the introduction of the punishment opportunity.

This study addresses this gap by integrating anecdotal insights from fishers to validate local extinctions and enhance data reliability. Additionally, it examines fishers' perceptions of shifting baselines for 23 species previously identified to be at risk of local extinction. Our findings revealed that most fishermen perceived population decline and rarity in more than half of the species identified as threatened with local extinction by a framework developed in 2019, suggesting that the findings likely reflect genuine ecological patterns, rather than local attitudes about the general state of fisheries. Gear types use appeared to influence perceptions of species rarity and population declines, indicating that fishers using diverse gear types tend to have broader ecological knowledge of reef fish populations compared to those specializing in a single type of gear. However, fishing experience did not affect perceptions of species rarity and population decline, supporting the concept of homophily and highlighting the effective knowledge transmission from older to younger fishers along the Kenyan coastline. Overall, this study demonstrates that local ecological knowledge is a valuable tool for assessing fish species' threat status and offers complementary insights that can enhance fisheries management efforts.</div></div>","PeriodicalId":48427,"journal":{"name":"Marine Policy","volume":"177 ","pages":"Article 106650"},"PeriodicalIF":3.5,"publicationDate":"2025-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143562689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study’s findings were as follows. First, incremental changes in fisheries’ production resource extraction are the primary cause of desertification of these marine environments. Second, from 1978 to 2016, a discernible desertification trend was evident for China’s fishery capture environments, offshore catches are about 60 % higher than allowable catches. Since the onset of the new millennium, many factors have hurt the deterioration of unit catches, production share, and resource quality every year<strong>.</strong> Third, desertification of fishery capture environments is linked directly to overfishing and external environmental damage. Fourth, centralized policies on marine fishery resource management and the absence of incentivizing institutional arrangements are the underlying causes of the problem. Last, but not least, developing clear property rights and appropriate regulations should feature centrally in the governance of marine fishery resources. Policy measures should be developed to motivate fishing communities, social organizations, and other key stakeholders to participate in governing fisheries' desertification.

We found that the governance groups of an MPA in the southwest, an area of intense fishing pressure on coral reefs, possess moderate to low capabilities for marine resource management with respect to authority (0.567), capacity (0.638), and power (0.49), indicating some success but also room for improvement. In contrast, governance capacity was notably deficient in two MPAs in the northwest, as reflected by their low authority, negative capacity scores, and insufficient power. Next, we used the Regulation Based Classification System to assess MPAs protection level. We found that while MPAs feature multiple zones based on allowed uses, the areas designated for extractive use are at risk due to exploitative activities and recurrent violation of regulations, suggesting that rules’ enforcement only provide moderate protection. The primary contributing factor to these infractions was the inadequate enforcement of regulations by the governance groups. Overall, the effectiveness of local MPA governance in Madagascar is variable but weak under the co-management frameworks studied here, with significant improvements needed in governance capacity.
