Bluefish is a food fish that lives in the Atlantic Ocean from Nova Scotia to the southern tip of South America. Some also live in the Indian Ocean, the Mediterranean Sea, and the Pacific Ocean around Australia. Most bluefishes grow 15 to 24 inches (38 to 61 centimeters) long and weigh from 1 to 4 pounds (0.5 to 1.8 kilograms). But some bluefishes grow almost 4 feet (1.2 meters) long and weigh more than 30 pounds (14 kilograms).
The bluefish feeds on smaller fish. It is fierce and often kills more fish than it can eat. Bluefishes usually swim in schools (groups) that may extend for several miles. Their fine flavor makes them a profitable catch for the fishing industry. Bluefishes are also popular sport fishes because they fight fiercely when hooked.
