TL;DR: Existing methods of sperm quality assessment in fish are reviewed, the factors affecting quality are surveyed and how the application of computer-calculated motility analysis may achieve a better understanding and quantification of the impact of aquaculture practices on sperm quality and fertilisation success is shown.

TL;DR: Computer assisted sperm analysis provides a simple and rapid quantitative assessment of the quality of fish sperm and may predict its ability to fertilise eggs and in combination with CASA, morphological measurements can be used to determine the causes of reduced sperm motility.

TL;DR: Computer assisted sperm analysis is shown for the first time to provide a rapid and quantitative measure of the effects of environmental pollutants on the quality of fish sperm, suggesting concentrations of cadmium which have been found to be present in fish gonads as a result of bioaccumulation from the water or diet may decrease the motility of sperm during maturation or storage in the testis.

TL;DR: Redundancy analysis showed a distinct and significant clustering of the gut microbiota of individuals consuming an AXOS diet, demonstrating a shift in the hindgut microbiome of fish consuming different preparation of AXOS, with potential application as prebiotics.

TL;DR: A new integrated approach including computer assisted sperm analysis (CASA), viability staining and fertilization was used to study the quality of cryodiluents used in fish sperm cryopreservation as mentioned in this paper.
