The spermatozoa of most fish species are immotile in the testis and seminal plasma.
Therefore, motility is induced after the spermatozoa are released into the aqueous …

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 …

The knowledge and scientific history of maternal and paternal aspects of reproduction dates
back several decades, though only recently are fishery scientists and managers giving this …

This contribution reviews existing literature and some new own findings on teleost sperm
motility and factors controlling it, emphasizing selected marine species. In marine teleosts …

In most species, fish spermatozoa activate their motility on contact with the external medium
(sea or fresh water depending of their reproductive habitat). Their flagella immediately …

after along period of spermatogenesis (several weeks to months), marine fish spermatozoa
are delivered at male spawning in seawater (sw) at the same time as ova. in some fish …

Factors such as gamete quality can profoundly affect fertility, but the spawning micro-
environment that surrounds the spermatozoa and eggs during gamete contact has largely …

Like the spermatozoa of most other fish species spawning in fresh water, Arctic charr
Sahelinus alpinus sperm were short‐lived (mean 42 s) after activation and their swimming …

Female mate choice after copulation or spawning is cryptic when a female differentially
influences the fertilization success of sperm from different males. We tested whether ovarian …

The effects of salinity of holding water of 5‰, 20‰ or 35‰ on seasonal reproductive
development, plasma steroid levels, the efficacy of luteinizing hormone releasing hormone …
