This study developed a joint dynamic species distribution model for 10 important fish species in the Bohai Sea summer ecosystem from 2010 to 2019. The model was used to explore the biological drivers in the spatio-temporal dynamics of four economically important fish species: <em>Engraulis japonicus</em>, <em>Larimichthys polyactis</em>, <em>Setipinna taty</em>, and <em>Pampus argenteu</em>s. The results showed that the low-economic-value predators <em>Liparis tanakae</em> and <em>Lophius litulon</em> appeared more frequently in <em>E</em>. <em>japonicus</em> hotspots, which is consistent with the idea that <em>E</em>. <em>japonicus</em> is an important food source of these two fish species. The biomass of <em>L</em>. <em>tanakae</em> and <em>L</em>. <em>litulon</em> was supported by key prey species such as <em>E</em>. <em>japonicus</em>, whilst exerting negative interaction effects on other fish stocks, including those of <em>L</em>. <em>polyactis</em>, <em>S</em>. <em>taty</em> and <em>P</em>. <em>argenteus</em> (predation and competitive interactions were reflected by negative covariation in spatiotemporal densities). Because of the \"food-predation risk trade-off\", <em>L</em>. <em>polyactis</em> and <em>E</em>. <em>japonicus</em> (often accompanied by top predators) exhibited greater differentiation in density hotspots. The model revealed the four species assemblages with their own clear spatio-temporal patterns, providing support for decoupling fisheries for species caught together and regulating the abundance of low-economic-value predatory fish to minimize adverse biologically driven effects on the recovery of economically valuable fish stocks. Our study can serve as a management decision-making framework for multispecies fisheries.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"267 ","pages":"Article 107739"},"PeriodicalIF":4.8,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143931761","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}

It presents a methodological framework that integrates beach surface changes, BCC evolution, regional economic impacts, and adaptation costs by applying updated coastal evolution data and IPCC AR6 SLR scenarios.

This study analyzes three beach nourishment-based adaptation strategies to maintain the BCC, assessing the required sediment resources and costs for each. Adaptation priorities can be determined based on the avoided GDP losses relative to nourishment costs, with the strategy being the most economically viable in areas with intensive sun-and-beach tourism.

As efforts to restore ecological health in urban coasts grow, strategies that retrofit habitat enhancement units, or ‘eco-units', onto existing seawalls have gained attention due to their ability to enhance biodiversity after installation. However, key functional measurements of the ecological communities that grow on eco-units remain limited, and concerns are emerging regarding the environmental costs of eco-unit production relative to their functional benefits. In this study, we compare the functional performance of eco-units deployed in Singapore with the environmental costs of their production and installation. Life cycle assessment (LCA) revealed that the carbon and nutrient removal capabilities of eco-unit communities were small compared to the climate change impact and marine eutrophication potential of their fabrication. Substituting Ordinary Portland Cement with Supplementary Cementitious Materials could substantially reduce the environmental impact of eco-units and offers a more effective means of reducing net emissions than relying solely on biological processes. Our findings highlight the importance of considering production-related environmental costs when evaluating the sustainability of eco-engineered strategies and indicate the critical role of material selection in the overall impact of eco-unit projects. Eco-units also provide other ecosystem services that are not part of LCA models and these need to be assessed using frameworks that consider a wider range of eco-unit benefits.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"267 ","pages":"Article 107721"},"PeriodicalIF":4.8,"publicationDate":"2025-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143916418","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}

Diversification of gear types in fisheries using bottom towed gears to encompass low environmental impact methods, such as static gear, is one way to reduce dependency on damaging fishing methods. Here we report on trials investigating how the use of white Light Emitting Diodes (LEDs; Fishtek Marine PotLights) affect catch rates of northern shrimp (<em>Pandalus borealis;</em> normally caught using trawls) across three different pot designs off the west coast of Scotland. We also caught the valuable Norway lobster (<em>Nephrops norvegicus</em>) and valueless poor cod (<em>Trisopterus minutus</em>) and considered occurrences and catch rates of these species. Illuminated pots resulted in significant increases in catch per unit effort (CPUE; ind. pot<sup>−1</sup> 24 h<sup>−1</sup>) of northern shrimp for all pot types up to maximum mean of 4.6 ± 4.5 shrimp pot<sup>−1</sup> 24 h<sup>−1</sup> (illuminated shrimp tubes specifically designed to catch shrimp; range = &lt;0.1–11.1). However, despite the substantial increase in CPUE of northern shrimp due to illumination, these quantities do not constitute commercially viable catch volumes. Furthermore, illuminated pots resulted in high juvenile poor cod bycatch (88 % increase in catch rates across all pot types) and reduced catches of Norway lobster (48 % reduction in catch rates across all pots). The high presence of poor cod in catches in response to illumination mirrors the response observed for the closely related cod (<em>Gadus morhua</em>) using the same methods elsewhere, adding evidence on how fishing with light propagates in ecosystems. Finally, to explain our results we propose an ”Attraction Cascade” hypothesis, as there is no documented evidence of phototactic behaviour. Taken together, these results suggest that, when pot type and fishing area are configured for specific target species, illumination may offer promise of increased CPUE and even baitless fishing in pot fisheries and an alternative to trawl fisheries for northern shrimp.</div></div>","PeriodicalId":54698,"journal":{"name":"Ocean & Coastal Management","volume":"267 ","pages":"Article 107663"},"PeriodicalIF":4.8,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143902011","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 evaluates control rules assuming uncertainty in the design of a precautionary strategy, so that a novel multistep process can improve the Mexican legal guidelines for the geoduck clam fishery. Based on an age-structured population decay model, four biological reference points were defined as i) management threshold point, ii) target reference point, iii) limit reference point, and iv) depleted. Each reference point (RP) was associated with different management tactics and actions because there are differences between effectively managing a geoduck clam fishery and recovering a geoduck clam population. The rationale for this analysis was to develop a novel fishery management proposal and provide updated guidelines for the Mexican geoduck clam fishery. All of them were based on international guidelines recommended by the ONU-FAO through the Code of Conduct for Responsible Fisheries, the Reference Points for Fisheries Management, and the adaptive management framework. The results showed the need to change the paradigm of legal guidelines for the geoduck clam fishery. In this situation, the fishing authorities (stakeholders) could use the reference points proposed here as a general scheme for Fisheries Management.
