The Pacific Bluefin Tuna is a large species of tuna found in the western and eastern Pacific Ocean. It is known for its streamlined body and can grow up to 10 feet long and weigh over 1,000 pounds. This fish is highly migratory, traveling long distances in search of food, primarily feeding on smaller fish and squid. Pacific Bluefin Tuna is highly valued in the seafood market, especially in Japan, where it is a key ingredient in sushi and sashimi. Due to overfishing, its population has significantly declined, leading to conservation efforts aimed at protecting this species and ensuring sustainable fishing practices.
