Summary: The development of industrial mariculture in Peruvian coasts will continue to grow but its monospecific nature has negative impacts on the ecosystem, biodiversity, and fishery resources. To address these issues, a sustainable production model called Integrated Multi-Trophic Aquaculture (IMTA) is proposed for Argopecten purpuratus cultivation in Samanco Bay. This model aims to achieve greater efficiency, competitiveness, and profitability while ensuring environmental balance. The adoption of this model can be adapted to other scenarios, and collaboration between academia, private companies, and relevant authorities is crucial in this process.

Summary: Recirculated aquaculture systems (RAS) are a new technology in land-based aquaculture that aim to increase food production while reducing negative environmental effects. However, questions about RAS production methods and social acceptability have emerged. This paper examines the potential issues of RAS using the current understanding of social acceptability. While concerns about environmental effects are not expected to be the same as in existing aquaculture, competition for land and energy costs are key considerations for industry expansion. Core determining factors for social acceptability, such as legitimacy, credibility, and trust, also need to be considered.

Summary: This paper critically examines the unequal development of social sustainability and suggests that social learning can serve as an insightful anchor for conceptualizing and operationalizing social sustainability. By showcasing multi-stakeholder schemes in various environmental governance areas, the paper reveals commonalities between social sustainability and social learning, as well as the potential for cross-fertilization between the two concepts. The paper emphasizes the importance of managing the dynamics between collaboration and conflict in multi-stakeholder governance schemes in order to achieve innovations in social sustainability.

Summary: This study analyzed the bacterial community characteristics of the Pelteobagrus fulvidraco integrated multi-trophic aquaculture system (YPS) and the water environment using high throughput sequencing technology and water analysis. The results showed that the system met the growth requirements of Pelteobagrus fulvidraco and different dominant bacterial genera were observed in different seasons. The study provides a theoretical basis for regulating the YPS.

Summary: This study aims to provide a generic framework for quantifying nutrient retention efficiency in integrated multi-trophic aquaculture (IMTA) systems and found that various biological and environmental factors may limit retention efficiencies. The results show that retention efficiencies of 45%-75% for closed systems and 40%-50% for open systems are more realistic based on evaluation against the theoretical reference frame.

Summary: Marine aquaculture mitigates environmental problems and periphyton-based biofilters are a promising technology for water treatment. The hydrodynamics of the system affect the growth of periphyton biomass and its ability to remove nutrients and produce dissolved oxygen. Integration of periphyton biofilters in recirculating aquaculture systems preserves water and improves water quality for fish.

Summary: Through stable isotope analysis, this study identified sea cucumber as the most important extractive co-cultured species in the IMTA system, followed by suspension-feeding bivalves, with cultured seaweeds having the least impact on waste reduction. The lack of isotopic consistency between IMTA and control feeders suggests minimal contribution of aquaculture waste to the neighboring coastal environment.

Summary: The integration of bioremediation systems is a promising technique to reduce the environmental impact of aquaculture effluents, allowing for nutrient recycling and high-value by-product creation. Halophyte plants, such as Sarcocornia neei, have shown high efficiency in removing nutrients from marine aquaculture wastewater. Further studies should investigate the growth rates and nutrient removal efficiency of S. neei under different conditions for potential industrial-scale applications.

Summary: The concepts of Nature-based Solutions (NbS) and the Blue Economy (BE) are key sustainability frameworks currently in policy dialogues. However, the lack of a strong operational definition for the Blue Economy has hindered investment, impacting investor confidence and adoption by policymakers and practitioners. Identifying specific sectors and activities within the Blue Economy that also meet the criteria for Nature-based Solutions could potentially unlock financing for ecosystem services, as shown by examining aquaculture activities.

Summary: The concentration of human population along coastlines has significant impacts on ocean and societal health. Two scenarios for 2030 are proposed: 'Command and (out of) Control' focusing on the current trajectory, and 'Living and Connecting' emphasizing interactions between oceans and society to achieve Sustainable Development Goals. Actions towards the latter scenario include improving marine citizenship, equitable power distribution, economic incentives for sustainability, and stronger regulations for ocean and human health.

Summary: The hypothesis of this study was that increased growth in spring, stimulated by temperature and daylength, leads to oxidative stress and changes in antioxidant utilization in Atlantic salmon. The study found that vitamin E and vitamin C concentrations decreased in the spring and were restored in the autumn, while astaxanthin concentration remained constant during the spring and summer and increased in the autumn. Cataract and melanin spots were observed during the spring and early summer. However, the concentrations of malondialdehyde and astaxanthin did not support the hypothesis, and more data is needed to draw conclusions on the effects of oxidative stress on melanin spots.

Summary: Palmaria palmata, also known as dulse, is a red macroalga found in the North Atlantic. It has a long history of use as food and efforts are being made to cultivate it due to increasing demand. However, challenges such as low spore release and germination rates need to be overcome for sustainable commercial production. This review provides a summary of the species' biology, ecology, and nutrient composition as food, as well as recent advancements in cultivation techniques and regulations for wild harvesting.

Summary: Light quality has significant effects on the growth, nutrient removal, and biochemical composition of Chlorella sorokiniana in aquaculture wastewater. White light maximizes biomass production, while red light and blue light finely tune the specific biochemical components. Blue light is particularly beneficial for pigment content and the removal of TOC, TN, and NH3-N is mainly driven by nonmicroalgal pathways.

Summary: This study found that climate messages centered around the Great Barrier Reef (GBR) are more effective in strengthening intentions to adopt energy reduction behaviors. However, they are limited in motivating more impactful civic and social behaviors, including those seeking to influence climate policy support. Messages emphasizing collective efficacy can enhance message effect and influence the uptake of a broader range of behaviors. Emotions related to distress played a significant role in this effect. This research offers an alternative for expanding beyond traditional climate communication strategies.
