Fish sperm motility assessment as a tool for aquaculture research, a historical approach

V. Gallego, J.F. Asturiano

Abstract

Fish sperm motility is nowadays considered the best biomarker for the quality of fish spermatozoa, and sperm motion parameters from more than 300 fish species have been reported in 1500 scientific articles covering a wide range of topics, from molecular biology to ecology. The most studied topics have been i) the sperm storage (involving both the use of chilled-storage protocols for short-term periods, and sperm cryopreservation techniques for long-term storage), ii) the sperm physiology (fathom in the spermatozoa activation process and the whole propulsion machinery of the sperm cells), and iii) the broodstock management (covering aspects such as rearing conditions, dietary requirements or hormonal induction treatments). In addition, other aquaculture and ecological topics such as iv) the knowledge of the breeding cycle of the species, v) the phenomenon of the sperm competition, and vi) ecotoxicological studies for the evaluation of aquatic environments, have also been approached from the evaluation of sperm motion performance.

Therefore fish sperm motility assessment can serve as a potential tool for aquaculture and ecological purposes, covering key topics of fundamental and applied research. This review gives an overview of the major research areas in which fish sperm motility have been applied successfully.
