Abstract
Cryopreservation is a technique that makes long term storage of fish semen possible. The objectives of the present study were to determine the effects of different stages of cryopreservation and individual variability of fish in the cryopreservation process. This study involved five stages of cryopreservation (fresh sperm sperm extender after equilibration time after vapor phase and after freezing) and three different fish. Sperm movement and velocity distribution for fresh and after frozen-thawed semen were evaluated using an automated semen analyzer. The motility of red tilapia fish sperm decreased gradually in the freezing process. The highest value of motility was obtained at fresh sperm (96.93 0.53) followed by sperm with extender (92.64 1.05) after equilibration time (84.86 2.26) and after vapor phase (67.82 3.28) whilst the lowest value of motility was obtained for sperm after freezing (61.39 3.62). For individual fish Fish 1 significantly showed the highest total motility (77.50 1.86).
