Fish semen proteomics - New opportunities in fish reproductive research

This is the first review to cover current knowledge of fish semen proteomics, based primarily on results published during the last two years. This new information has been integrated into the existing knowledge base of basic and applied research concerning fish reproduction. The identification of several new proteins sheds new light on the biochemistry and physiology of seminal plasma and spermatozoa, and allows for a better understanding of the relationship between blood and seminal plasma. The discovery of a plethora of newly identified proteins that are released from spermatozoa in response to cryogenic damage contributes to a better understanding of the mechanisms involved in cryopreservation. It also provides researchers with a list of potential biomarkers that are important for the evaluation of cryopreservation success. This study is relevant both for many types of scientists, including fish biologists and cryobiologists, and for practitioners, including fish management and hatchery personnel.
