sexing musky? get your head out of the gutter

[John Miller]

I think its funny that the sex of a fish is a category on the release report.  I am not aware of any sexual dimorphism in musky, other than females getting larger than males.  Size of course is also relative to age.  Are anglers expected to vent the fish's genitalia to assess its sex?  Is there another technique being used that I am not ware of?

You have to look at the anal duct (urogenital region if you want to sound official) of the fish.  If it looks like pear it's generally a female.  If it looks like keyhole it's generally a male.  Or you can just ask them.  You do speak musky right?

I knew that somewhere in my archives I had info on sexing muskies. Here's a diagram we used to hand out. Also a photo I found on the internet. It probably is important to document the sex. But I think we felt it more important to release the fish without too much unnecessary handling. But if you want to check the sex, just turn the fish onto its back while in the water and check it out.

The same method will work for cats, dogs, squirrels, cows, and humans. But I'd be careful.
