... further complicates the issue. We claim that broader perspectives that go beyond usual costs and benefits-which recently have questioned the feasibility of parts of this industry (Sumaila et al., 2023)-and procedural environmental impact assessments are crucial and timely. The technologies employed to extract minerals vary according to the targeted resource and environment where activities will take place. ...

... Global warming leads to increased seawater temperatures, changes in ocean current patterns, and increased seawater acidity, all of which can damage the lobster's natural habitat and reduce the productivity of the fishery (Gattuso et al., 2015). It is therefore important for Blue Economy policies to integrate climate change mitigation strategies to ensure the sustainability of marine ecosystems and the economic well-being of communities dependent on marine resources (Kaczan et al., 2023;Lam et al., 2020;Le Blanc et al., 2017). ...

... Chemical contamination, resulting from human activities, plays a significant role in the global decline of fish biodiversity within aquatic ecosystems. This form of pollution introduces a range of harmful substances into water bodies, yielding subtle yet far-reaching consequences for fish populations (Alam et al., 2023). The intricate interplay between chemical pollutants and biodiversity loss operates across various scales, from individual fish to entire ecosystems. ...

... DSM related impacts, including those on nutrient enrichment [77], alteration of water properties [78], oxygen depletion [79], sediment toxicity [78], removal of fauna and flora [80][81][82], changes in temperature and noise [83] have clear connections with the delivery of key ocean ecosystem services through their influence on ecosystem structure and processes. Furthermore, Biodiversity loss, habitat disruption, and pollution already pose significant threats to marine ecosystems [84], and their effects could be greatly intensified by DSM, which has the potential to impact the supporting services by disturbing deep-sea ecosystems that function as critical breeding and feeding grounds for numerous marine species [85]. ...

... There is no comprehensive official statistic on the number of divers and dives worldwide. However, Schuhbauer et al. (2023) have estimated every year, 8.9-13.6 million divers and snorkelers participate in marine dive tourism activities worldwide. Several studies have been conducted to estimate the value of ecosystem services related to recreational diving (Ruiz-Frau et al., 2013;Failler et al., 2015;Rees et al., 2015;Zunino et al., 2020), focusing particularly on evaluating naturebased solutions such as habitats, species, and marine protected areas. ...

... Globally, the fish consumption rate is growing faster than the global population due to the awareness of the health benefits of consuming fish, increased incomes, and rising urbanization (Issifu et al., 2022). Fish and fishery products are critical for nutrition and food security and play a vital role in the economy of many countries, particularly those in the developing world (FAO, 2020). ...

... As pelagic fishes, billfish species display relatively high levels of proteins, omega-3 fatty acids, vitamins, and minerals, and represent a potential major source of essential nutrients for tropical coastal communities (Bodin et al., 2017;Sardenne et al., 2020;Sioen et al., 2009;Sirot et al., 2012;Wesolowska et al., 2024). Billfishes are mainly caught by industrial fisheries (using longlines and gillnets, and as bycatch of purse seine) in offshore areas (Peatman et al., 2023), but also by recreational and artisanal gears in more coastal fishing grounds (IOTC Secretariat, 2022), and have therefore a high economic and cultural value in tropical areas where they are distributed (Kadagi et al., 2022). In this context, quantifying MeHg concentrations and %MeHg in billfishes appears essential to determine more precisely to what extent these species can be safely consumed, and to provide appropriate dietary advices. ...

... Where conservation planning literature considers costs, most attention is given to management costs. Opportunity costs, when considered, might appear low in absolute terms but can be very high relative to local incomes 11 , and institutional factors that increase transaction costs are largely underestimated in planning for conservation. Low-income areas with low opportunity costs might appear promising as low-cost conservation options; however, considerable institutional complexity (for example, unclear property rights) -which is harder to measure -can greatly increase the true costs of achieving equitable conservation or restoration 12 . ...

... It combines bagging and random feature selection to add an extra layer of randomness to bootstrap and reduce the impact of outliers on prediction results.
