Protocols for the cryopreservation of fish gametes have been developed for many different
fish species, in special, freshwater salmonids and cyprinids. Methods for sperm freezing …

This article reviews the use of hormonal treatments to enhance sperm production in
aquaculture fish and the methods available for evaluating sperm quality. The different types …

Cryopreservation causes osmotic changes and oxidative damage that have sublethal and
lethal effects on spermatozoa. We examined these osmotic and oxidative effects on common …

Contents The sperm of European eel shows a high density and the time of spermatozoa
motility is very short after activation with sea water. These characteristics make difficult the …

Elasmobranchs are one of the most endangered vertebrate groups on the planet, but
despite this situation the use of reproductive techniques in elasmobranch conservation …

Research into an optimal cryoprotectant, its concentration and equilibration time underlies
the successful cryopreservation of dromedary camel spermatozoa. This study assessed the …

European eel males can be artificially matured (1.5 IU hCG/g fish), but the regulatory
mechanisms of their reproductive development are practically unknown. Spermatogenic …

This study developed the cryopreservation of brown-marbled grouper spermatozoa for
practical application. We examined 32 cryodiluents, developed from four types of …

Sperm production has been obtained from European and Japanese eels, but its quality and
quantity tend to be changeable. So, its cryopreservation has been tried in both species …

In order to study different storage conditions, dilution ratios and additives for fresh European
eel sperm were assayed to determinate the optimum conditions for short‐term storage. Two …
