male VS female marlin

[SERprise]

How do you tell the difference between a male and female marlin are there any differences?

[Glenn W]

The books I have indicate there are no external differences between male and female Marlins ( Blue, Black, White or Striped). Therefore, the only way to tell is cut them open.
According to Charles O' Mather, Generally Pacific Blue Marlin greater than 300lbs are female--- smaller fish are comprised of both sexes.

Yup...



Visually there are no distinguishing marks. Fight wise though the little male is a son of a ***** on the end of a string. They pound for pound are over the top strong. They seem to go places the she fish won't when fighting. We encounter quite a few of what I believe to be males in the pocket. They're harder to hook and when we do they have a tendency to run for the shallower water. I have vid, sucky as it is of one that took me into 20 feet and you can see him running between coral heads...
On the leader they tend to stay strong and determined and getting them to calm down just seems to never happen.

If the fish has trouble picking which skirt they want...defiantly a female!!! The males usually grab the first skirt they see!!!
