The majority of the experiments having said that didn't show adjustments in hematocrit, indicating the biofloc system didn't adversely have an effect on the hematological Houses of fish. The main function of hemoglobin is to transport oxygen in the fuel exchange organ to peripheral tissues, in addition to a decrease in hemoglobin below worry conditions is usually manifested by a decrease in the speed of hemoglobin synthesis, leading to impaired oxygen provide into the tissues and inevitably leading to a lessen in RBCs through hemolysis [fifty three,fifty four].
