Question

How old can a 680 pound marlin fish be? How do you determine the age of marlins?

Answer 1

That's quite a wide range, but 7-13 years for a 680 pound fish means it grows very fast -- that's 50-100 pounds a year.

There's currently a study going on to determine the growth rates more accurately, but all I was able to find was a description of the method -- it seems they don't have results yet. But it describes how they determine the ages.

Answer 3

According to this website, probably 7-13 years old. (680 pounds = 310 kg).

(These are black marlin taken near Australia; other species in other areas might be different.)
