What is it about?
Canned tuna is one of the world's most important seafood products. It provides an affordable source of protein and is traded globally, yet estimating future demand has remained difficult because consumption patterns differ widely among countries. This study introduces a new forecasting approach based on the Gamma Model to estimate global canned tuna demand. The model captures how seafood consumption changes as national income rises and applies these relationships to long-term economic and population projections. The results suggest that global demand for canned tuna is likely to continue increasing, although the pace of growth will vary across regions as diets and incomes change. The study also compares future demand with the availability of tuna resources, highlighting the potential challenges of balancing market demand with sustainable fisheries management.

Why is it important?
Reliable forecasts of seafood demand are essential for governments, fishery managers, seafood companies, and international organizations. Underestimating future demand could increase pressure on tuna stocks, while overestimating it could lead to unnecessary investments and inefficient management. This research provides a practical method for predicting long-term canned tuna demand using internationally available economic and demographic data. By linking market demand with the biological limits of tuna resources, the study offers valuable information for sustainable fisheries management, food security planning, and investment decisions throughout the global tuna supply chain.
Perspectives
This study demonstrates that demand forecasting can become a useful bridge between fisheries economics and resource management. Sustainable tuna fisheries depend not only on understanding tuna stock status and resource availability but also on anticipating how consumers' preferences will evolve over time. As the global population grows and incomes continue to rise in many developing countries, demand for seafood is expected to increase further. Future research should integrate market forecasts with climate change, technological innovation, changing consumer preferences, and evolving fisheries management measures. Combining these factors will help policymakers and industry stakeholders develop more resilient strategies for securing both tuna resources and global food supplies.
