Here are some of the most popular raw fish dishes from around the world:
Sushi
- Sushi is a Japanese dish that consists of small rolls or pieces of vinegar-seasoned rice topped with raw fish or other seafood.
- Some popular types of sushi include nigiri, which is a small piece of fish pressed onto a ball of rice, and maki, which is a sushi roll filled with a variety of ingredients.

Ceviche
Ceviche is a popular dish in many Latin American countries, particularly in Peru. It typically consists of raw fish that is marinated in citrus juices, such as lime or lemon, along with onions, chili peppers, and other seasonings.
Because the acid in the citrus juices “cooks” the fish, ceviche is technically not raw. However, it is still considered a raw fish dish because the fish is not cooked with heat.
Poke
- Poke is a Hawaiian dish that is made with chunks of raw fish, typically ahi tuna, that is marinated in soy sauce and other seasonings.
- The fish is usually served over a bed of rice and topped with vegetables, such as avocado, cucumber, and seaweed.

Overall, raw fish dishes offer a delicious and unique way to enjoy seafood from around the world.
