This cortisol enhance brings about phagocytic and complement activity suppression in blood and head-kidneys, a minimize in the amount of lymphocytes, and an increase in susceptibility to an infection [72]. The vast majority of experiments confirmed a big decrease in serum cortisol in fish cultured with biofloc, and it had been argued this lessen was the result of proving that biofloc had an influence of relieving worry in fish [30,32,34,47,55,58].
