Ocean Tuna

Ocean Tuna By Astra Aqua – Premium Vietnamese Seafood For Global Markets

Introduction to Vietnam’s Ocean Tuna

Ocean Tuna (Thunnus spp.) is among the most valuable marine species, often called “Blue Gold” for its high economic and nutritional value. Its deep red flesh, firm texture, and naturally sweet flavor make it one of the most sought-after seafood items in global cuisine.

Vietnam is currently one of the top five tuna exporters in the world, with annual output exceeding 150,000 tons. The central coastal provinces — Binh Dinh, Phu Yen, and Khanh Hoa — are renowned for their rich tuna resources and skilled fishing communities.

Astra Aqua Int’l Co., Ltd is proud to be one of Vietnam’s leading exporters of premium frozen tuna products, supplying high-quality tuna to international markets such as Japan, the United States, Europe, Korea, and the Middle East.

With a focus on quality, safety, and freshness, Astra Aqua offers a diverse range of Ocean Tuna products — from Sashimi-grade Saku Blocks to Tuna Steak, Cube, Tataki, and Canned Tuna — designed to meet the exacting standards of importers, retailers, and food service professionals worldwide.

Key Characteristics of Ocean Tuna

Ocean Tuna is a migratory deep-sea fish with a streamlined body and exceptional strength, capable of swimming long distances across tropical and subtropical waters. Depending on the species and region, adult tuna can reach lengths of 40–150 cm and weights up to 100 kg.

The main commercial tuna species include:

• Yellowfin Tuna (Thunnus albacares) – lean texture, pinkish-red flesh, mild flavor; ideal for sashimi and steak.

• Bigeye Tuna (Thunnus obesus) – higher fat content, deep red meat, rich umami flavor; preferred for tataki and sushi.

• Skipjack Tuna (Katsuwonus pelamis) – smaller size, firm meat, often used for canned products.

The naturally red coloration of tuna meat comes from myoglobin — an oxygen-binding protein in muscle fibers. When handled and frozen correctly, tuna retains its vivid color, elasticity, and fresh flavor even after thawing.

With low fat, high protein, and clean taste, Ocean Tuna is a premium ingredient in international cuisines, especially Japanese sashimi, sushi, poke bowls, grilled steak, and salads.

Exceptional Nutritional Value

Tuna is recognized as one of the healthiest and most nutrient-rich seafoods available.
A 100g serving provides 23–25g of high-quality protein, essential for muscle growth and energy.

It’s also an excellent source of Omega-3 fatty acids (DHA & EPA), which help lower cholesterol, improve heart health, and enhance brain function. The fish contains abundant vitamins B6, B12, D, and E, supporting metabolism, nerve function, and immunity.

Essential minerals such as iron, zinc, phosphorus, and magnesium contribute to strong bones, healthy blood circulation, and overall vitality.

Because of its low-calorie and high-protein profile, tuna is a favorite among health-conscious consumers and athletes following low-fat, keto, or high-protein diets.

Health benefits of tuna include:

• Promotes lean muscle growth and reduces fat.

• Improves heart and brain health.

• Enhances focus and memory.

• Strengthens immunity and overall well-being.

Thanks to this balance of taste and nutrition, tuna is a global symbol of healthy cuisine.
