The objective of this study was to determine the effect of freezing on the function in Atlantic salmon Salmo salar spermatozoa. The semen was frozen in Cortland's medium+1.3M dimethyl sulphoxide+0.3M glucose+2% bovine serum albumin (final concentration) in a ratio of 1:3 (semen:cryoprotectant) as...

Cryopreservation of Atlantic salmon Salmo salar sperm: effects on sperm physiology
The knowledge of sperm quality in the broodstock males of different ages is a prerequisite to identify the reproductive ability of cultivated fish for the hatchery management. Thus, in this work, we analysed sperm function of the semen stored of broodstock males of rainbow trout (Oncorhychus myki...

This study was designed to test a vitrification method on spermatozoa of sex-reversed rainbow trout and determine the ability of sucrose, dimethyl sulfoxide (DMSO), bovine serum albumin (BSA) and seminal plasma (SP) to protect these cells from cryoinjuries. The vitrification medium comprised a st...

The aims of this investigation were to test a novel technology comprising cryoprotectant-free vitrification of the spermatozoa of rainbow trout and to study the ability of sucrose and components of seminal plasma to protect these cells from cryo-injuries. Spermatozoa were isolated and vitrified u...

In this article we describe basic aspects of the sperm biology of lebranche mullet (Mugil liza) in the wild and in captivity, in particular assessing the effects of salinity (0, 10, 20, 30, 35, 40, 50 and 60 g L-1) and pH (6, 7, 8, 9 and 10) on sperm motility. Our results indicate that the highes...

Short-term storage of semen is a useful strategy for preservation of fish spermatozoa in reproductive management, however, no information is available on Patagonian blenny (Eleginops maclovinus) semen. This study was designed to evaluate the effects of in vitro storage on sperm function parameter...

The short-term storage of salmonid semen is a viable method for in vitro fertilisation. Previous studies have found that short-term storage affects sperm motility, compromising quality and fertilising capacity. However, the functional characteristics of the spermatozoa of O.mykiss during storage ...

Short-term storage of semen is a useful strategy for preservation of fish spermatozoa. However, there is a significantly decrease on sperm function mainly due to oxidative stress. In this way, sodium alginate plays an important role as free radical scavenger compound. Accordingly, the aim of our ...
