We have thirty tilapia in our Aquatic Ecosystem's Mini-Fish Farm recirculating system. They are about 1-1.5 lbs each. We have not had any apparent breeding taking place. We sacrificed two fish last month for internal investigation. We were lucky? One was a male and one was a gravid female. Is there a way to visually or less invasively determine the sex of tilapia?
