TLDR
Osmolality higher than 200mOsmkg(-1) significantly decreased the percentage of motile sperm, while osmolability of 300mO smkg(- 1) or above totally suppressed sperm motility.About:

Studying sperm motility in marine fish: an overview on the state of the art

TL;DR: A paradigm has been developed which establishes a link between external osmolality (sea water), internal ionic concentration and control of axonemal activity in spermatozoa within species where these data have been established.
Journal ArticleDOI
Frenetic activation of fish spermatozoa flagella entails short-term motility, portending their precocious decadence.
TL;DR: The present understanding of physico-chemical mechanisms by which flagellar motility is activated (mostly through osmotic and ionic regulation) and then propels sperm cells at speed is explained.

TL;DR: The research and information from the literature showed that higher osmolarities promote greater longevity in anuran sperm, and some freshwater fish sperm and that anuran and cryptobranchid sperm maintained membrane integrity long after the cessation of motility, demonstrating a preferential sharing of energy reserves toward the maintenance of membrane integrity.

TL;DR: By increasing osmolality, the velocity of spermatozoa reached the highest value while wave length, amplitude, number of waves and curvatures also were at their highest values.

Sperm motility in fishes. (II) Effects of ions and osmolality: A review
TL;DR: The roles of these ions on sperm motility in Salmonidae, Cyprinidae, Acipenseridae and marine fishes are reviewed and their relationship with seminal plasma composition is reviewed.
Journal ArticleDOI
Some problems related to the assessment of sperm motility in freshwater fish
TL;DR: Motility requires a high dilution for initiation of synchronous motility in 100% of spermatozoa; a two-step procedure is necessary, with an initial dilution of 1 to 100 in a medium that keeps the spermatozosa immotile and allows good mixing of the viscous semen.

Sperm motility in fishes. I. Effects of temperature and pH: a review
TL;DR: The effects of temperature and pH on the motility of spermatozoa in three fish species: salmonids, cyprinids and sturgeons are reviewed and summarized.
Journal ArticleDOI
Biology of sperm and artificial reproduction in carp
TL;DR: The basic work on carp sperm is reviewed, the technologies of artificial insemination are described and the sperm is of a primitive type with uncondensed chromatin and a small midpiece and motility depends mainly on endogenous ATP stores.
Journal ArticleDOI
Relationship between sperm ATP content and motility of carp spermatozoa.
TL;DR: Results suggest that motility of carp spermatozoa depends on sperm ATP synthesized by mitochondrial respiration mainly stored before activation in low osmolality conditions, where the mitochondrial oxidative phosphorylation is unable to compensate for the ATP hydrolysis required to sustain motility.
