“…Chinese mitten crab (Eriocheir sinensis) has been considered a delicacy with delicious taste and high nutritional value for centuries (Ma et al, 2017). In recent decades, overfishing, habitat destruction and other human factors have seriously threatened the safety of the wild resources of E. sinensis (Helmer et al, 2019;Karcher et al, 2020). To relieve the pressure on wild populations, aquaculture projects have been launched since the 1990s and represent an effective solution to efficiently producing crabs, especially after breakthroughs in the stock enhancement, seed production and farming technologies of E. sinensis (Bachmann-Vargas et al, 2020;Nahuelhual et al, 2019).…”

A 60‐day feeding experiment was performed to investigate the survival, growth, body composition, antioxidant capacity and related gene expression of Eriocheir sinensis which were fed diets with different lipid sources under three salinities. Five feeds were formulated with one of the candidate oils (fish oil, soybean oil, linseed oil, colza oil or palm oil) and were named FO, SO, LO, CO or PO respectively. Results showed that the survival rate (SR) of E. sinensis showed a decreasing tendency as the salinity increased. But SR was not significantly affected by dietary lipid sources at each salinity. Weight gain rate (WGR) were highest in the treatment of FO/PO at a salinity of 0.5‰, CO/FO/SO at a salinity of 2‰ and LO at a salinity of 6‰ respectively. At salinities of 0.5‰ and 2‰, the transcription of pro‐inflammatory and antioxidant genes in LO was significantly higher than that in FO or PO. While at a salinity of 6‰, the transcription of detected genes in FO was markedly increased compared to that in the vegetable oil treatments. At each salinity, the eicosapentaenoic acid (EPA) contents showed comparable values among different dietary treatments. However, the docosahexaenoic acid (DHA) contents in E. sinensis fed the diets with FO were still significantly higher than those with vegetable oils. These results showed that increasing salinity decreased the antioxidant capacity and therefore negatively affected the survival and growth rates of experimental animals. The beneficial effects of FO on survival and growth performance were eliminated by increasing the salinity to 6‰, which could be due to the increased lipid peroxidation and inflammatory response caused by salinity stress. It was concluded that at the salinity of 0.5‰ and 2‰, the recommended lipid sources were FO/PO and CO/FO/SO respectively. While at the salinity of 6‰, LO was the most ideal lipid source for juvenile E. sinensis.

“…Through the fast-growing number of Locally Managed Marine Areas (LMMA) or enabling legislation guaranteeing customary marine tenure, the Pacific has witnessed a ‘rennaissance’ of locally based and community-driven initiatives of environmental and resource management (Johannes 2002 ; Govan 2009 ; Friedlander 2018 ) making CBMRM the primary regional strategy and policy orientation across the Pacific (Cinner et al 2012 ; Cohen et al 2015 ; Hanich et al 2018 ). Regional organizations, conservation NGOs, and private foundations now stress the importance for state agencies to support and upscale CBMRM initiatives (SPC 2010 , 2021 ; Karcher et al 2020 ; Steenbergen et al 2022 ). Yet, the process by which these seemingly simple strategies move from bullet points in project plan documents towards gaining reality at the project site are not well understood.…”

This paper presents an ethnographic case study of the design and revision of a decentralized marine management scheme implemented on the island of Moorea, French Polynesia named Plan de Gestion de l’Espace Maritime (PGEM). Drawing on an analysis of over 50 consultative workshops and meetings, held from 2018 to 2021 during the PGEM revision, we document the materials, discourses, and practices local stakeholders (e.g., fishers, cultural and environmental activists, government staff, and scientists) combine to build their interpretations of PGEM success or failure. We examine the diversity of domains these interpretations draw from (ecology, marine livelihoods, culture, religion, and politics) and how they are put into practice in people’s engagement with—or resistance to—the local marine management and governance design. Our results highlight how the controversies around the revision of Moorea’s PGEM overflowed the boundaries of ecology as construed by scientific experts. Stakeholders interpreted “marine resource management” as something well beyond just “marine resources” to include politics, identity, Polynesian cosmology, and livelihoods. Our findings provide generalizable patterns for understanding how natural-resource management policies are received and repurposed by local actors.

“…Such rights are enacted, in particular, in the context of both offshore and inshore fisheries, which are central to the economy of Oceanian states and the livelihoods of their (mostly coastal) inhabitants (Gillett 2016 ), increasingly so since the COVID-19 pandemic (Walters et al 2021 ). They are also expressed through the ever-evolving policy landscape designed to manage these fisheries (Karcher et al 2020 ).…”
