ऑक्सीजन की उच्च मांग: कैटफिश को अन्य मछलियों की तुलना में अधिक ऑक्सीजन की आवश्यकता होती है, जिसके लिए अतिरिक्त एरिएटर का उपयोग किया जा सकता है।

Mansour and Esteban [28] reported a major boost in hematocrit in O. niloticus cultured with biofloc made out of carbon resources of rice bran and wheat-milling by-solution, but there was no sizeable change in biofloc designed with glucose as being a carbon supply. Most of the reports however did not display alterations in hematocrit, indicating which the biofloc system did not adversely influence the hematological Attributes of fish. The primary operate of hemoglobin is to move oxygen from your fuel Trade organ to peripheral tissues, and a reduce in hemoglobin beneath strain conditions is often manifested by a decrease in the rate of hemoglobin synthesis, leading to impaired oxygen supply for the tissues and sooner or later leading to a reduce in RBCs through hemolysis [53,54].
