“…This is mainly explained by the lack of competition for resources as the diets between these fish and jellyfish overlap significantly (Brodeur et al., 2008; Shoji et al., 2009), and the structuring role that small pelagic fishes play in the food webs as trophic controls (Cury & Shannon, 2004). In the case of fish abundance, we did not find any relationship between fishery catches and the abundance of Actinopteri reads ( p = .145, Table S2), possibly reflecting the targeted nature of the fishery in the region, focused on anchoveta, sardines, and hake (Gozzer‐Wuest et al., 2023). However, these targeted fisheries could also support the hypothesis of an increase in jellyfish abundance due to the depletion of small pelagic fish.…”

The hadopelagic environment remains highly understudied due to the inherent difficulties in sampling at these depths. The use of sediment environmental DNA (eDNA) can overcome some of these restrictions as settled and preserved DNA represent an archive of the biological communities. We use sediment eDNA to assess changes in the community within one of the world's most productive open‐ocean ecosystems: the Atacama Trench. The ecosystems around the Atacama Trench have been intensively fished and are affected by climate oscillations, but the understanding of potential impacts on the marine community is limited. We sampled five sites using sediment cores at water depths from 2400 to ~8000 m. The chronologies of the sedimentary record were determined using 210Pbex. Environmental DNA was extracted from core slices and metabarcoding was used to identify the eukaryote community using two separate primer pairs for different sections of the 18S rRNA gene (V9 and V7) effectively targeting pelagic taxa. The reconstructed communities were similar among markers and mainly composed of chordates and members of the Chromista kingdom. Alpha diversity was estimated for all sites in intervals of 15 years (from 1842 to 2018), showing a severe drop in biodiversity from 1970 to 1985 that aligns with one of the strongest known El Niño events and extensive fishing efforts during the time. We find a direct impact of sea surface temperature on the community composition over time. Fish and cnidarian read abundance was examined separately to determine whether fishing had a direct impact, but no direct relation was found. These results demonstrate that sediment eDNA can be a valuable emerging tool providing insight in historical perspectives on ecosystem developments. This study constitutes an important step toward an improved understanding of the importance of environmental and anthropogenic drivers in affecting open and deep ocean communities.

“…The MC is an official platform where all registered fishers enrolled in the target fishery can apply to act as representatives (SUBPESCA, 2013). Even though the MC is considered as highly participative, several issues have been raised regarding its mode of representation (Tapia-Jopia, 2022) and performance (Gozzer-Wuest et al, 2023), which reflect on the agreements reached by its members (CNP, 2015;Oceana, 2020;Tribunal Ambiental, 2021). Moreover, the MC has failed to design and implement a needed recovery program as it was agreed in 2016 (SUBPESCA, 2022b).…”

Market-based approaches to seafood sustainability have gained popularity in the last decade. Market-based tools, such as certification and ratings systems, enable seafood companies along supply chains to engage in sustainability initiatives while reducing business risks. Yet, these approaches are predominantly utilized in Global North markets and often evaluate performance against standards that build upon resource-intensive, mainstream fisheries management models. These management models have yielded successful outcomes in industrial fisheries, mainly in the Global North, where science, management, and compliance authorities are well-resourced. In contrast, artisanal and small-scale fisheries in the Global South have seen limited success in applying mainstream management approaches. Co-management approaches based on secure tenure rights, which emphasize effective partnerships between management authorities and resource users with specific rights over the resources, have shown better outcomes in these contexts. Despite this, market-based tools have largely overlooked co-management principles and tenure rights in their standards. To address this gap, this paper introduces two step-wise evaluative methods designed for the ratings system FishSource, aiming to score whether fishers enjoy secure tenure rights and effectively participate in decision making. The proposed methods use available secondary data to evaluate these crucial aspects of well-managed and equitable small-scale fisheries, while aligning with international policy instruments like the Food and Agriculture Organization Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries and the United Nations Sustainable Development Goals.

“…The capacity of defining, preparing and establishing partnerships between operators, scientists, policymakers and civil society are the strengths behind PPA projects (Gozzer-Wuest et al, 2023). Undertaking a path towards certification can have additional and unanticipated effects, related to social and governance outcomes, i.e.…”

“…Management authorities are beginning to use certification programs, applied to evaluate the sustainability performance of fisheries throughout the world, to provide a framework for recognizing best practice actions and for identifying and analyzing the challenges regarding the adoption of measures that can achieve improvements in fisheries management in the short and long term (Gozzer-Wuest et al, 2023). In particular, Marine Stewardship Council (MSC) standards are increasingly used before making sweeping adjustments aimed at enhancing efficiencies for all fisheries, not just those seeking certification.…”

Data availability and participatory approach: the right mix for enhancing Mediterranean fisheries’ sustainability

et al. 2023

A misalignment between the legislation and the effectiveness of Mediterranean fisheries management has emerged due to the status of the stocks (still largely in overfishing) and the discontent of stakeholders regarding management plans and tools that are not always recognized as appropriate to the characteristics of the concerned fisheries. Stakeholders’ involvement in management processes is one of the main pillars of the Common Fisheries Policy revision. The literature underlines, in an increasingly urgent manner, the importance of stakeholders fully understanding the contents of management plans and, vice versa, necessary for the successful implementation of policies. Focusing on the path towards sustainability endorsed by the BluFish project, the paper tries to provide an answer about the sustainability of some selected Southern Italian fisheries, by adopting the assessment approach of the Marine Stewardship Council. The assessment approach, based on a set of Performance Indicators and on a well-defined scoring scheme, focuses on three dimensions of sustainability. In addition to the classic assessment of the state of the stocks, there is an extensive screening of the impact of anthropic activity such as fishing on the entire ecosystem, including both the impact on accessory species and on vulnerable habitats and species. The evaluation adopted goes even further, with an approach that also includes the management and governance sphere, also trying to evaluate the level of involvement of the operators in the decision-making process. The paper illustrates that the selected fisheries are not fully sustainable but some of them have excellent potential for improvement even in the short term by identifying and implementing the appropriate action. The most relevant weaknesses identified refer to the low scores obtained for sustainability of stocks, mainly around the Harvest Control Rules (HCR) and the Harvest Strategy indicators, highlighting the importance of improving the management of the assessed stocks. The paper highlights how data and scientific knowledge availability is essential for a detailed mapping and evaluation of fishing activities but also that the path towards more sustainable and responsible fisheries does not work without a strong participation of all the key stakeholders.
