Abstract: Cryopreservation and the effect of additives on the plasma membrane stability, motility, enzyme activity, membrane lipid composition, and ultrastructural injury of sperm of Pseudosciaena crocea, were examined in this study. Results indicated that the addition of trehalose (TH) and bovine serum albumin (BSA) provided significantly better results in the motility test compared to sucrose. Some BSA groups, showed significantly increased semen motility and effective enzyme activity. There were no significant differences between the cholesterol (CHO) composition for fresh sperm and cryopreserved sperm stored in 3 g/L BSA or 8.56 g/L TH+3 g/L BSA. Ultrastructural injury included damaged membrane, lost mitochondria, or broken flagella, whereas the majority of the freeze-thawed sperm remained morphologically normal. In conclusion, the addition of 3 g/L BSA and 8.56 g/L TH+3 g/L BSA significantly increased semen quality.
