One of the 3 most important concepts in pond mgt is Total mortalities (natural mortalities plus harvest), as a part of population mgt. Many fish starve or are eaten as newborn yoy. Survivors are eaten as young fish year 1 or later. Some die from other causes like starvation, disease or weather/water quality/stress. Those are all natural mortalities with large variance year to year. Your job is to watch those factors - natural mortalities (or measure for them by survey) and harvest fish - total mortalities to meet your goals and situation. Not an easy job !
