Description
The Atlantic Mackerel is typically an open ocean fish with voracious feeding habits. They travel in schools that often contain thousands of fish. The swift swimming mackerel has a streamlined body and swims at high speeds for extended periods of time searching for food. All individuals within a specific school tend to be the same size. Since cruising speed increases significantly with age and size, scientists believe that conformity of body size within a specific school is necessary to allow all fish to maintain identical swimming speeds. Mackerel may grow as large as 7-1/2 pounds and have a maximum age of about 20 years.
