貝類の市場規模、シェア、成長分析：種類別、流通チャネル別、地域別 - 産業予測 2025～2032年

貝類の世界市場規模は2023年に623億米ドルと評価され、予測期間（2025-2032年）のCAGRは3.4%で、2024年の644億2,000万米ドルから2032年には841億7,000万米ドルに成長する見通しです。

貝類市場は、消化可能なタンパク質、必須アミノ酸、重要なミネラルなど、貝類の重要な栄養的利点を重視する消費者の健康志向の高まりによって、成長の態勢が整いつつあります。2019年の世界の水産物消費量は1人当たり19.8kgと若干減少するもの、貝類消費量ではエビが84.6%を占め依然としてトップであり、次いでカニが25.3%となっています。貝類の需要の増加は、レストラン、ホスピタリティ、料理部門におけるその重要性を裏付けています。しかし、この需要による価格上昇が予想されるため、低所得世帯にとっては課題となるかもしれないです。貝類が将来的に持続可能な食品の選択肢となるためには、アクセシビリティと値ごろ感を向上させ、消費の妨げとなる障壁を取り除くことが重要です。

結論と推奨事項

Global Shellfish Market size was valued at USD 62.3 billion in 2023 and is poised to grow from USD 64.42 billion in 2024 to USD 84.17 billion by 2032, growing at a CAGR of 3.4% during the forecast period (2025-2032).

The shellfish market is poised for growth, driven by rising health consciousness among consumers who value the significant nutritional benefits of shellfish, including digestible proteins, essential amino acids, and vital minerals. Despite a slight decline in global seafood consumption to 19.8 kg per capita in 2019, shrimp remains the leader in shellfish consumption, comprising 84.6%, followed by crab at 25.3%. The increasing demand for shellfish underscores its importance in the restaurant, hospitality, and culinary sectors. However, projected price increases due to this demand may pose challenges for low-income households. To ensure shellfish can be a sustainable future food choice, it's critical to enhance accessibility and affordability, thereby removing barriers that could hinder consumption.

Driver of the Global Shellfish Market

The global shellfish market has experienced substantial growth, largely due to the numerous health benefits associated with shellfish consumption. Packed with lean protein, healthy fats, and essential minerals, shellfish stands out as a nutritious food choice. Research indicates that regular shellfish intake can enhance immune function, support weight management, and contribute to overall well-being. Rich in zinc, magnesium, and vitamin B12, shellfish offers low-calorie, high-protein options, making it effective in combating obesity-a condition that affected nearly 42.4% of the population in the U.S. in 2018. Moreover, the presence of omega-3 fatty acids helps promote satiety, while further studies reveal that shellfish consumption significantly lowers heart attack risks, particularly among men.

Restraints in the Global Shellfish Market

The global shellfish market faces significant challenges primarily due to the prevalence of shellfish allergies, which is recognized as one of the most common food allergies. This issue particularly impacts the Asia-Pacific region, where there is considerable demand for shellfish but also a high incidence of allergic reactions. Tropomyosin, a protein found in shellfish, is responsible for triggering severe anaphylactic responses by activating the immune system and causing the release of histamines, leading to varying degrees of allergic reactions. Research indicates that approximately 3% of adults are affected by shellfish allergies, with rates being particularly high in Hong Kong, Singapore, and the Philippines, where prevalence can reach between 5.12% and 7.71%. The study showed that crustaceans are the primary culprits, affecting 3.8% of individuals, followed by finfish at 1.2% and mollusks at 1.0%. Such widespread allergic reactions are obstructing the overall growth and expansion of the shellfish market.

Market Trends of the Global Shellfish Market

The Global Shellfish market is witnessing a significant trend towards innovation in plant-based seafood alternatives, driven by the rising consumer preference for sustainable and health-conscious food options. As awareness around animal welfare intensifies, food producers are proactively developing novel plant-based substitutes that mimic the taste and texture of traditional shellfish. This shift not only addresses the ethical and environmental concerns associated with seafood consumption but also caters to the expanding vegan and vegetarian demographics seeking savory seafood experiences. Consequently, the market is poised for growth as consumers increasingly pursue products that align with their dietary values while satisfying their seafood cravings.
