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: 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: Integrated multi-trophic aquaculture (IMTA) systems integrate species from different trophic levels, reducing negative environmental impacts while assisting local economies and promoting long-term economic viability. However, further investigation is needed regarding social equity and acceptance, and governance analysis and institutional development are crucial for the success of IMTA.

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: This paper aims to explore the potential exploitation of the biomass of the polychaete worm Sabella spallanzanii obtained from an Integrated Multi-Trophic Aquaculture (IMTA) system. The study finds that S. spallanzanii can effectively remove suspended matter and has the potential to be used as fish bait, an ornamental organism, and in fish feed markets. The research also demonstrates the feasibility of using S. spallanzanii as a sustainable source of animal proteins in the fish feed industry.

Summary: The study in the Los Lagos region of Chile reveals a correlation between salmon farming and mussel farming, with higher mussel production closer to salmon farms. Salmon farming contributes substantial nitrogen annually, while mussel farming extracts nitrogen from the inner seas of Los Lagos. The study suggests focusing on certain areas for integrated aquaculture management.

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: Field studies were conducted on a small-scale kelp and mussel farm in Cornwall, UK, to investigate the potential of seaweed and shellfish co-cultivation in regulating local dissolved nutrient concentrations. Results revealed typical seasonal variations in chemical, physical, and biological parameters, with no significant reductions in inorganic nutrient concentrations downstream from the farm. The effectiveness of nutrient regulation depends on local climatic and hydro-geochemical conditions, as well as the design and scale of integrated multi-trophic aquaculture (IMTA) systems.

Summary: Producing food according to sustainability principles is a strategic goal for many world institutions. Integrated Multi-Trophic Aquaculture (IMTA) meets these criteria. The Self-sufficient Integrated Multitrophic AquaPonic (SIMTAP) aims to reduce inputs and waste outputs while maximizing food production, with the selection of suitable fish, organisms, and plants playing a key role.

Summary: Aquaponics is promoted as a sustainable agricultural practice, but its economic sustainability is challenging due to external benefits necessitating public intervention. A proposed aquaponic system for producing ornamental fish and lettuce was estimated to have an environmental cost of 10,700 EUR annually, mainly attributed to industrial processes. Life cycle assessment and economic valuation methods can potentially assess the cost-effectiveness of aquaponics from an environmental perspective.

Summary: The study found that there were no significant differences in the responses to ocean acidification and warming between different populations, but intrinsic differences among populations may be related to natural variability in CO2, NO3-, and seawater temperatures driven by coastal upwelling. Further research with additional populations and fluctuating climate change conditions is needed to determine precisely how natural variability in environmental conditions might influence a species' response to climate change.

Summary: The rapid global spread of COVID-19 and other anthropogenic threats such as global climate change are posing significant economic challenges to the aquaculture sector. A positive correlation between the impacts of the pandemic and anthropogenic stressors was detected, with different effects on various parts of the supply chain. The use of integrated multitrophic aquaculture (IMTA) methods may enhance resilience to multiple stressors, providing different market options during the COVID-19 pandemic.

Summary: Seaweed farming has been promoted as a climate solution, but the carbon sink function is diminished due to consumption and alternative applications. Seaweeds can reduce greenhouse gas emissions through carbon offset and potentially through reducing enteric methane emissions from ruminants and bioenergy production. However, further research is needed to understand seaweeds' carbon cycling and contributions.

Summary: This study successfully valorized the red alga Gracilaria chilensis by sequentially extracting phycobiliproteins (PBPs) and agar. The extracted PBPs (R-phycoerythrin and R-phycocyanin) were recovered and purified, while agar with similar physical properties as directly extracted agar from G. chilensis was obtained. The agar obtained after PBPs extraction showed no inhibitory effects on microbial growth and allowed effective nucleic acid separation.

Summary: In this study, algal-based biochar was transformed into carbon nanotubes by microwave irradiation. Different species of algae were pyrolyzed to obtain biochar, which served as precursors for CNT growth with ferrocene as the catalyst. The characteristics of the synthesized CNTs varied depending on the biochar source, such as the carbon content and mineral ash content. Low catalyst concentration was found to be sufficient for growth promotion, and microwave heating conditions affected the optical properties of CNTs.

Summary: The distribution and productivity of seaweeds are influenced by changes in temperature and inorganic nitrogen availability. The effect of the nitrate: ammonium ratio on physiological traits and gametophyte development of Macrocystis was investigated, showing that NH4+ led to negative NO3- uptake rates and reduced growth rates. Different developmental stages and physiological traits may have varying thermal tolerance windows.
