Pond Boss Forums FISH & FISHING Sunfish-Including Largemouth and Smallmouth Bass Sexing Redear Sunfish?

So, are two confirmed RES enough samples?

I have a fairly large year class of 7" RES so I can do more fillet sampling and confirmation of sex in the coming weeks. I can leave the "unhappy" fish pictures out of the posts if you like. Just curious if we have seen enough to make attempting to sex RES a little easier or if I should sacrifice a few more RES on the alter of knowledge.

Thoughts?
