About the bluefin tuna
Bluefin tuna can swim at a speed of 80 km per hour.
It is a dark blue on its top side and a grey or silvery white on its bottom side. It preys on smaller fish such as herring, mackerel and sardines.
Several fishermen claim to hold the record for catching the largest bluefin tuna. However, the official world record is held by Ken Fraser, who, in 1979, caught a bluefin tuna weighing 1,496 pounds near the coast of Nova Scotia.
Unlike most fish, bluefin tuna is warm-blooded, meaning it will swim in both cold water and warm water. Migration notwithstanding, the bluefin can be found as much in the waters of Newfoundland as those of Iceland, the Gulf of Mexico and the Mediterranean Sea.
