Abstract: Blood samples were collected from 72 Black scorpion fish (Scorpaena porcus) to establish baseline blood serum chemistry values. Mean ± S.E values obtained by auto analyzer were as follows: sodium, 195.07 ± 1.7000 mmol L-1; potassium, 3.810 ± 0.1850 mmol L-1; chlorine, 174.82 ± 1.5600; phosphorus, 15.122 ± 0.2640 mg dL; calcium 14.66 ± 0.2830 mmol L-1; iron 15.639 ± 0.6560 μg dL-1; very low-density lipoprotein, 7.65 ± 0.3800 mg dL-1; low-density lipoprotein, 15.36 ± 1.6600 mg dL-1; high-density lipoprotein, 20.36 ± 0.7100 mg dL-1; alanine aminotransferase, 28.89 ± 2.26 IU L-1 and aspartate aminotransferase, 224.11 ± 14.09 IU L-1.
