Farms that are successful in keeping the DO at no less than 4 ppm even in the morning are usually very successful, with good growth rates, a high survival rate and a low FCR. When the DO is maintained at at least 4 ppm, there is seldom a problem with white feces disease or bacterial infections. In contrast, on farms where the DO drops below 4 ppm at night, the shrimp will grow slowly during the culture period and white feces disease is very common.
