The contribution of aquaculture systems to global aquaculture production
Since 2000, aquaculture became well‐integrated into the global food system. Aquaculture systems are highly diverse, producing globally equal amounts of fed and extractive species. In Asia and Africa, inland aquaculture provides the bulk of aquaculture production, while in the Americas, Europe, and Oceania, marine aquaculture dominates. The realized growth of annual production since 2000 is due to intensification, the use of more and better feeds, improved production management, and increased attention to biosecurity. Fed and extractive aquaculture, both need to pay more attention to scaling, site selection, and the health of the wider production environment. In terms of land use, aquaculture is more efficient than terrestrial animal production. Still, water use remains a challenge. More attention should be given to water recycling in land‐based systems, reducing water consumption and facilitating nutrient recovery and reuse. Future development should focus on making aquaculture climate neutral and on reducing environmental impacts, both inland and at sea. More attention must be given to making aquaculture an important part of local food systems on all continents, as is the case in Asia today. Integration of aquaculture into local nutrition‐sensitive, circular, and sustainable food systems should become the major driver for future aquaculture system development.

Responsible Aquaculture in 2050: Valuing Local Conditions and Human Innovations will be Key to Success
As aquaculture production expands, we must avoid mistakes made during increasing intensification of agriculture. Understanding environmental impacts and measures to mitigate them is important for designing responsible aquaculture production systems. There are four realistic goals that can make future aquaculture operations more sustainable and productive: (1) improvement of management practices to create more efficient and diverse systems at every production level; (2) emphasis on local decisionmaking, human capacity development, and collective action to generate productive aquaculture systems that fit into societal constraints and demands; (3) development of risk management efforts for all systems that reduce disease problems, eliminate antibiotic and drug abuse, and prevent exotic organism introduction into local waters; and (4) creation of systems to better identify more sustainably grown aquaculture products in the market and promote them to individual consumers. By 2050, seafood will be predominantly sourced through aquaculture, including not only finfish and invertebrates but also seaweeds.

Aquaculture‐Based Ecological Restoration: A Further Step of Regenerative and Restorative Aquaculture
Aquaculture is increasingly recognized not only as a solution for global food security but also as a potential tool for ecological restoration. As marine biodiversity continues to face increasing threats and ongoing decline, there is a growing need to develop conservation‐oriented approaches, particularly within the aquaculture sector. This paper explores the integration of mariculture practices—such as integrated multi‐trophic aquaculture (IMTA) and recirculating aquaculture systems (RASs)—with ecological restoration strategies aimed at rehabilitating degraded habitats and restoring ecosystem functioning. But further, the paper introduces the potential of commercial aquaculture in supporting the cultivation of species of conservation interest alongside traditional commercial species (aquaculture‐assisted ecological restoration). We claim that combining commercial aquaculture with active restoration allows the scaling up of restoration efforts (i.e., one of the major bottlenecks at present), enhancing the recovery of key habitat‐forming organisms, such as seaweeds, seagrasses, and endangered invertebrates, while also generating socioeconomic benefits. Drawing from recent case studies, we propose the feasibility and advantages of a “reproduce to restore” paradigm. This approach positions aquaculture as a nature‐based solution capable of supporting biodiversity goals under international frameworks such as the EU Biodiversity Strategy 2030 and the Kunming‐Montreal Global Biodiversity Framework.

A 20-year retrospective review of global aquaculture
The sustainability of aquaculture has been debated intensely since 2000, when a review on the net contribution of aquaculture to world fish supplies was published in
Nature
. This paper reviews the developments in global aquaculture from 1997 to 2017, incorporating all industry sub-sectors and highlighting the integration of aquaculture in the global food system. Inland aquaculture—especially in Asia—has contributed the most to global production volumes and food security. Major gains have also occurred in aquaculture feed efficiency and fish nutrition, lowering the fish-in–fish-out ratio for all fed species, although the dependence on marine ingredients persists and reliance on terrestrial ingredients has increased. The culture of both molluscs and seaweed is increasingly recognized for its ecosystem services; however, the quantification, valuation, and market development of these services remain rare. The potential for molluscs and seaweed to support global nutritional security is underexploited. Management of pathogens, parasites, and pests remains a sustainability challenge industry-wide, and the effects of climate change on aquaculture remain uncertain and difficult to validate. Pressure on the aquaculture industry to embrace comprehensive sustainability measures during this 20-year period have improved the governance, technology, siting, and management in many cases.
The volume of global aquaculture production has tripled since 2000 with positive trends in environmental performance, but the sector faces mounting challenges including pathogen management, pollution, climate change, and increasing dependence on land-based resource systems.

Sustainable development of climate-resilient aquaculture and culture-based fisheries through adaptation of abiotic stresses: a review
Climate change is an inevitable event that obstructs the output of aquaculture farms and culture-based fisheries in open waters. It poses a serious threat to global food security, altering biodiversity, ecosystems, and global fish output by displacing fish stocks from their natural habitats. When compared to freshwater aquaculture, marine/coastal aquaculture is more affected. To combat the effects of climate change, several mitigation methods and adaptations are being implemented, emphasizing future demands of affordable protein. Selective breeding, species diversification, and aquaculture systems like integrated multi-trophic aquaculture, aquaponics, and recirculating aquaculture system are some of the most widely accepted and adapted solutions. Further research on intervention in seed and feed in terms of quality improvement, bioresource utilization, and technological and genetic improvement is required. Climate change policies from the government are also essential. The present study differs from previous reviews by portraying the various abiotic stress factors contributing to the drastic climate change, encompassing adaptation strategies followed in distinct aquaculture sources such as freshwater, inland saline water, brackish water, coastal waters, and culture-based capture fisheries with its future implications.
