What tuna species is the largest is the world?
If you said Bluefin, you are correct. The Bluefin tuna is the largest of them all. The largest one currently on record belongs to fisherman Ken Fraser, who caught a bluefin tuna off the coast of Nova Scotia, Canada in 1979 at 1,496 LBS. Whoa! That's a lot of sashimi or tons of sushi to be made! And at today's cost, it's reported that the finest Bluefin Tuna can be valued at $200 per LBS. Wow! Mr Ken Frazer could have sold his catch at 300K.
Why are bluefin tunas grow so big? Because they eat too much! LOL! The Atlantic Bluefin Tuna is typically found in the northern part of the Atlantic Ocean, ranging from Newfoundland down to the Gulf of Mexico. The fish has been known to dive as deep as 1,000 meters to live and hunt. They don't reach that large size on a small diet, and it has a wide range of food options from childhood through adulthood.
So, if or whenever you go tuna fishing, you might be lucky in catching the next biggest bluefin tuna!
