Thanks for the input Snipe and jpsdad. I do have the "recovery tank" at the pond by using an ice chest with an aerator in it. But after reading you comments, I am no way prepared or educated enough to do proper sexing without harming the fish. I will refrain from doing that part of my plan. But will do some tests on bass I catch from the wild that I intend to filet anyway and try and get a grasp on the process.
Once again, the knowledge here is remarkable. And I am very thankful.
