Sperm Morphology, Physiology, Motility, and Cryopreservation in Percidae

Popis výsledku v původním jazyce

In percids, the spermatozoon is acrosomeless and asymmetrical in shape. The head of the spermatozoon is spherical and contains the genomic material. Mitochondria and proximal and distal centrioles are located in the midpiece of the spermatozoon. The fl agellum consists of an axoneme with a "9 + 2" mikrotubule structure surrounded by a plasma membrane. The length of spermatozoa fl agella is between 30 and 35 ?m. The volume of sperm and spermatozoa concentration highly differs among species and individuals. Seminal plasma is composed of both mineral and organic compounds and has osmolality about 300 mOsmol kg/1 to maintain the spermatozoa in the quiescent state. A hypo-osmotic shock is required to trigger initiation of spermatozoa motility after discharge into an aquatic environment. The duration of sperm motility lasts from several seconds to a few minutes, however sperm-motility kinetics (percentage of motile spermatozoa, spermatozoa velocity and beating frequency of fl agella) rapidly
