The use of motility as a measure of sperm quality in fish is reviewed. Computer assisted sperm analysis (CASA) provides a simple and rapid quantitative assessment of the quality of fish sperm and may predict its ability to fertilise eggs. It has been used to: monitor the effects of heavy metal pollutants, such as mercury and tributyltin, on sperm quality; to select broodstock; to improve the efficiency of cryopreservation and storage; and to optimise conditions for fertilisation. In combination with CASA, morphological measurements can be used to determine the causes of reduced sperm motility. Technical details for the use of CASA are described. (C) 2001 Elsevier Science Inc.
