The objective of this retrospective study was to evaluate causes of morbidity and mortality in 67 NFS housed in long-term professional care in United States aquaria from 1976-2022, including individuals born in the wild and those born in professional care. A review of necropsy and histopathology records was conducted to identify causes of morbidity and mortality, as well as associations among age, sex, and wild versus aquarium birth origin. Major causes of mortality included infectious diseases (n = 12), hemochromatosis (n = 10), undetermined (n = 10), and cardiovascular diseases (n = 8). Cause of mortality was significantly associated with sex (p = 0.015). Hemochromatosis and hepatic causes of mortality were identified exclusively in females. Infectious diseases were the most identified major cause of mortality and included septicemia (n = 7), toxoplasmosis (n = 3), leptospirosis (n = 1), and suppurative meningitis (n = 1). Of the septicemia cases, three were confirmed to be caused by <i>Pasteurella</i> sp. Hemochromatosis was the predominant cause of death in ten females from 8-25 years of age, with histopathology identifying hemochromatosis as a comorbidity in an additional male NFS.
