Bluefin tuna is known for its versatility, as it can be enjoyed raw, seared, grilled, or even canned.

In Japan, bluefin tuna holds cultural significance and is highly valued for its use in sushi and sashimi. Overfishing and high demand have led to concerns about the sustainability of bluefin tuna populations, leading to conservation efforts and regulations to protect this magnificent species.
