Congrats. Put the egg sacs in a minnow trap and it will be full in no time.
Nice fish! The minute after she spawns, her body start's making new eggs for next year. So it doesn't matter a dead fish is a dead fish. You can't can't tell the sex of the fish unless it's spew'n milt or eggs with out cut'n it open. Glad ya caught dinner. How did ya cook it? Got a good recipe?
