| Summary: | Abstract The tambaqui Colossoma macropomum is the main species of edible fish originating from fish farming in the Amazon region. This study aimed to determine and compare the blood physiology of tambaqui from fish farms in municipalities in the Metropolitan Region of Manaus, Amazonas, Brazil. Two fish farms were sampled in a semi-excavated pond-type breeding system in the five investigated towns. There were notable variations between Iranduba and Novo Airão in the erythrogram’s hematocrit, hemoglobin concentration, and erythrocytes, indicating signs of anemia and dehydration. Fish from Novo Airão and Iranduba have low levels of plasma biochemistry. Low levels of fatty molecules were detected in Manacapuru tambaqui. The leukogram and thrombogram assessed the similarities among tambaqui from different farms and communities and showed significant intraspecific variation. However, as seen by the elevated blood levels of triglycerides and cholesterol, fish from Manacapuru are fed an unsuitable diet. Determining the hematological parameters of C. macropomum tambaqui, the primary native species produced in Brazil, is crucial for defining the boundaries between healthy and diseased conditions for this significant aquaculture species. Supporting rural agricultural regulatory organizations, tambaqui producers, and researchers. |
