Read the thread below on how to tell them apart. Apparently, especially with the younger ones, it's difficult. No one posted a sure fire method, though. Apparently there are ways a biologist can tell easily, but it requires more than just a glance. Time we'd not like to take because it would either kill or seriously stress the fish.

But I have to ask, is there some reason it would be pertinent to know this? Are their habits different? Is one sex significantly larger than the other like with largemouth bass? Again, like bass, is one sex easier to catch? Is one sex more numerous than the other (might make a difference to a keep or release decision)?

I guess my real question would be: Why would this information help an angler on the water?

Thanks,

Buddy
