Short-term storage of semen is a simple and inexpensive procedure to deal with logistics of large-scale hatchery operations but can lead to oxidative stress and a significant decrease in sperm motility and velocity. To better understand the mechanisms responsible for the association of poor sperm quality with oxidative stress, in the present study we investigated the effect of refrigerated storage for 0, 24, 48, 72, and 144 h on sperm motility and curvilinear velocity and oxidant/antioxidant balance of common carp Cyprinus carpio.

Percentage of motile sperm was significantly (p 0.05) in total superoxide dismutase was detected after 48 h, and glutathione reductase and glutathione peroxidase activity demonstrated a significant increase after 72 h. These results provide an additional tool for the development and improvement of short-term sperm preservation procedures commonly applied in aquaculture.
