Tuna Species

In the vastness of our oceans, approximately 15 to 20 recognized species of tuna inhabit the waters. However, the specific number can fluctuate depending on taxonomic classifications and the inclusion of subspecies or local populations.

Here you have a closer look at 8 of the most significant types of Tuna:

  1. Thunnus albacares (Yellowfin Tuna): Easily recognizable by its robust, streamlined body and dark blue upper body, the Yellowfin Tuna is highly coveted in the fishing industry. It can grow up to 8 feet (2.4 meters) long and weigh over 400 pounds (180 kilograms). Found in the Atlantic, Indian, and Pacific oceans, it's sought after for its pink, flavorful flesh, perfect for sushi and grilled dishes.
  2. Thunnus alalunga (White Tuna or Albacore): Also known as Bonito del Norte, the White Tuna stands out for its slim, elongated shape and bluish upper body. It can reach lengths of up to 4.5 feet (1.4 meters) and weigh around 100 pounds (45 kilograms). Thriving in temperate and tropical waters of the Atlantic and Pacific, its white, delicate flesh is ideal for canning and sushi.
  3. Thunnus thynnus (Bluefin Tuna):Renowned for its exceptional taste, red meat and marbled texture, Bluefin Tuna is large and muscular, with a dark blue upper body. It can grow up to 10 feet (3 meters) long and weigh over 1300 pounds (590 kilograms). Found in the Atlantic and Mediterranean, it's prized in Japanese cuisine for its quality flesh.
  4. Thunnus obesus (Bigeye Tuna): Characterized by its large eyes and pink, flavorful flesh, the Bigeye Tuna shares similarities with yellowfin but has darker coloration.
  5. Katsuwonus pelamis (Skipjack Tuna): Featuring firm, red flesh, Skipjack Tuna is processed into fresh fillets, ideal for grilling or pan-searing. It's a popular choice due to its palatability.
  6. Thunnus maccoyii (Southern Bluefin Tuna): With a robust, muscular body and dark blue coloration, Southern Bluefin Tuna can grow up to 8 feet (2.4 meters) long and weigh over 440 pounds (200 kilograms). Appreciated in haute cuisine for its exceptional taste and texture.
