New FAO Data Highlight Aquaculture’s Growing Role in Food Security and Opportunities for Domestic Trout Production

Aquaculture has reached a historic milestone in global food production, with farmed aquatic animals now accounting for the majority of the world’s aquatic animal output. According to the Food and Agriculture Organization of the United Nations (FAO), aquaculture produced approximately 103 million metric tons of aquatic animals in 2024, representing 53% of total global production. Wild-capture fisheries contributed approximately 92 million metric tons.

The figures, reported in the FAO’s State of World Fisheries and Aquaculture 2026, highlight the growing importance of fish farming in meeting worldwide demand for nutritious food. For the United States trout industry, the findings reinforce the importance of domestic aquaculture and raise important questions about production efficiency, market access, environmental stewardship and the competitiveness of American-grown fish.

Worldwide fisheries and aquaculture production reached approximately 235 million metric tons in 2024. When algae are included, aquaculture production totaled approximately 141 million metric tons, valued at $391 billion. Aquaculture also supplied more than 59% of aquatic animal foods destined for human consumption.

The numbers reflect a major shift in the global seafood supply: aquaculture is no longer simply supplementing wild fisheries. It has become the primary driver of growth in aquatic animal production.

Why the Global Shift Matters for Trout Farmers

Wild-capture fisheries remain essential to seafood supply, but production from capture fisheries has largely leveled off. Aquaculture has provided most of the growth in aquatic food production over recent decades, helping meet rising demand without requiring a comparable increase in wild harvests.

For trout farmers, this trend reinforces the importance of a reliable domestic production sector. Farmed trout can contribute to the U.S. supply of high-quality protein while supporting agricultural businesses, rural employment, feed suppliers, processors, distributors and local economies.

The global figures also demonstrate the scale of the opportunity. As consumers, retailers and food-service businesses seek dependable seafood supplies, U.S. trout producers can compete by emphasizing product quality, consistent availability, traceability and the value of domestic production.

However, a growing global market does not automatically translate into greater opportunities for American farms. International producers operate under different cost structures, resource conditions, regulatory systems and market arrangements. Domestic trout farmers must be able to manage production costs, maintain healthy fish stocks, invest in appropriate technology and reach buyers in a competitive marketplace.

Feed Efficiency and Resource Management Remain Priorities

Feed is a major production expense for many trout farms, making feed conversion, nutrition and ingredient sourcing important to both operational performance and environmental responsibility.

The wider aquaculture industry has made substantial advances in feed formulation and nutritional management. Research and commercial innovation have helped producers improve efficiency and reduce dependence on marine ingredients in a number of farmed species. Nevertheless, progress varies by species and production system, and responsibly sourcing feed ingredients remains important.

For trout producers, continued attention to feed performance can support fish growth, production planning and business profitability. Nutrition strategies must be appropriate for trout at different stages of development, while maintaining fish health, product quality and efficient use of resources.

The global milestone also underscores the value of research into alternative feed ingredients, improved feed utilization and better measurement of production efficiency. Any changes must be evaluated for nutritional suitability, availability, cost and their effects on fish performance.

Water, Fish Health and Climate Resilience

The FAO identifies climate change, extreme weather, disease outbreaks and competition for water resources among the challenges facing future aquaculture growth. These issues are particularly relevant to freshwater producers, whose operations depend on suitable water quantity, quality and temperature.

Trout farming systems differ considerably, and their vulnerabilities depend on local conditions and production methods. Changes in water temperature or flow, for example, can affect fish health, oxygen requirements and production management. Disease prevention and biosecurity are also essential to protecting stocks and maintaining dependable operations.

Investments in water monitoring, system maintenance, fish-health programs, emergency planning and appropriate water-reuse technologies can help farms prepare for changing conditions. Research partnerships and practical information-sharing among producers can further strengthen the industry’s ability to respond to emerging risks.

Responsible environmental management is equally important. Effective production practices help protect receiving waters, maintain public confidence and demonstrate that trout farming can operate as part of a well-managed food system.

Domestic Production and Market Competitiveness

Global aquaculture production remains concentrated geographically. Asia accounted for approximately 89% of worldwide farmed aquatic animal production in 2024, with China representing a particularly large share. International seafood trade was valued at approximately $186 billion, and more than one-third of global aquatic animal production crossed international borders.

For U.S. trout farmers, these figures highlight both the scale of global competition and the importance of resilient domestic supply chains. Imported seafood plays a major role in the American marketplace, meaning domestic producers must compete on price, quality, reliability and access to customers.

American-grown trout offers buyers an additional domestic sourcing option. Producers can work with distributors, retailers, restaurants and institutional food-service purchasers to communicate product attributes, strengthen market relationships and identify opportunities for dependable regional supply.

Industry-wide efforts to improve consumer awareness may also help. Many consumers recognize seafood as a source of protein and other important nutrients, but may not fully understand the contribution of domestic aquaculture or the production practices involved in raising trout. Accurate, practical information can help customers make informed purchasing decisions without overstating the benefits of any one production method.

The Importance of Science-Based Policy and Industry Advocacy

As aquaculture becomes increasingly important to global food security, the regulatory and policy environment will help determine how effectively domestic producers can respond to market demand.

Trout farmers must navigate requirements involving water use, environmental protection, fish health, transportation and other aspects of production. Clear, science-based regulations can protect natural resources while giving producers the predictability needed to invest in infrastructure, technology and business growth.

The global production figures provide a useful context for discussions about domestic aquaculture policy. If farmed aquatic animals are already supplying a majority of worldwide production, supporting responsible domestic farms is an important consideration in food-system resilience and agricultural competitiveness.

For the United States Trout Farmers Association, this milestone reinforces the importance of representing trout producers, communicating the industry’s economic and nutritional contributions, supporting research and innovation, and advocating for policies that allow responsible farms to operate successfully.

Looking Ahead

The FAO’s findings show that aquaculture has become indispensable to the global food supply. The challenge now is to sustain that growth while improving production efficiency, protecting aquatic environments and strengthening resilience to climate and market disruptions.

U.S. trout farmers are part of that broader effort. Through sound management, continued innovation, responsible resource use and strong industry representation, domestic producers can help meet seafood demand while supporting American agricultural businesses and communities.

The global milestone is an important reminder that the future of aquatic food production will depend not only on how much the industry produces, but also on how efficiently, responsibly and competitively it does so.
