“…This impression is confirmed by many quantitative assessments of motility parameters (Cosson 2007a). Experimental values of the initial sperm speed of forward displacement in various species confirm a high velocity (expressed in mm/s): 150-180 in halibut , Vermeirssen et al 2004, 160 in fugu (Takai & Morisawa 1995), 130 (Cosson et al 2008a) or 65-100 (Trippel & Morgan 1994) in cod, 130 in hake (Cosson et al 2008a, Groison et al 2008, 215-230 in tuna (Cosson et al 2008b), 220 in turbot , Dreanno et al 1999c, and 120 (straight line velocity) in sea bass (Dreanno et al 1999a(Dreanno et al , 1999b, similar to values published by Abascal et al (2007). However, these velocity characteristics may be modulated by sperm microenvironment and particularly pH and osmolality of the SM.…”

After a long 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 species, as the ova micropyle closes quickly after release, these minute unicells, the spermatozoa, have to accomplish their task of reaching the micropyle within a very brief period (several seconds to minutes), for delivery of the haploid male genetic information to the ova. To achieve this goal, their high-performance motile equipment, the flagellum, must fully activate immediately on contact with the SW and then propel the sperm cell at an unusually high initial velocity. The cost of such 'hyperactivity' is a very rapid consumption of intracellular ATP that outstrips the supply. The spermatozoa become rapidly exhausted because mitochondria cannot compensate for this very fast flagellar energy consumption. Therefore, any spermatozoon ends up with two possibilities: either becoming exhausted and immotile or reaching the egg micropyle within its very short period of forward motility (in the range of tens of seconds) before micropyle closure in relation to both contact of SWand cortical reaction. The aim of the present review is to present step by step the successive events occurring in marine fish spermatozoa from activation until their full arrest of motility. The present knowledge of activation mechanisms is summarized, as well as a description of the motility parameters characterizing the motility period. As a complement, in vitro results on axonemal motility obtained after demembranation of flagella bring further understanding. The description of the sperm energetic content (ATP and other high energy compounds) and its evolution during the swimming period is also discussed. A general model aiming to explain all the successive cellular events occurring immediately after the activation is presented. This model is proposed as a guideline for understanding the events governing the sperm lifespan in the marine fish species that reproduce through external fertilization.

“…The effects of intra-testicular sperm maturation on motility parameters and the resulting changes of sperm quality over the reproductive period have been described for several fish species, yielding contrary results. Depending on the species investigated, seasonal effects on sperm quality exhibit a range of patterns, including increases, decreases and quadratic patterns with peaks in mid-season (Alavi et al, 2008(Alavi et al, , 2010Babiak et al, 2006;Christ et al, 1996;Hjirazaee et al, 2010;Johnson, 2012;Munkittrick and Moccia, 1987;Rouxel et al, 2008;Vermeirssen et al, 2004). The inconsistency of these results is probably the result of species-specific differences in maturation patterns and the resulting fluctuations in different sperm quality parameters over the reproductive season.…”

Sperm in hot water: Direct and indirect thermal challenges interact to impact on brown trout sperm quality

Climate change alters the thermal habitat of aquatic species on a global scale, generating novel environmental challenges during all life stages, including reproduction. Changes in water temperature profoundly influence the performance of ectothermic aquatic organisms. This is an especially crucial issue for migratory fish, because they traverse multiple environments in order to reproduce. In externally fertilizing migratory fish, gametes are affected by water temperature indirectly, within the reproductive organ in which they are produced during migration, as well as directly, upon release into the surrounding medium at the spawning grounds. Both direct (after release) and indirect (during production) thermal impacts on gamete quality have been investigated, but never in conjunction. Here, we assessed the cumulative influence of temperature on brown trout, Salmo trutta, sperm quality during sperm production (male acclimation temperature) as well as upon release (sperm activation water temperature) on two consecutive dates during the brown trout spawning season. Early in the season, warm acclimation of males reduced their fertilization probability (lower sperm velocity) when compared with cold-acclimated males, especially when the activation water temperature was also increased beyond the thermal optimum (resulting in a lower proportion of motile sperm with lower velocity). Later in the season, sperm quality was unaffected by acclimation temperature and thermal sensitivity of sperm was reduced. These results give novel insights into the complex impacts of climate change on fish sperm, with implications for the reproduction and management of hatchery and wild trout populations in future climate scenarios.

“…In landlocked salmon (Salmo salar m. sebago Girard), sperm volume increased during the reproductive season (Piironen, 1985). Endocrinological events that regulate spermiation and milt hydration make the comparisons difficult (Mylonas et al, 1997;Vermeirssen et al, 2004). Also Campos-Mendoza et al (2004) noted that variation in day length during spawning period affected the sperm volume in males.…”

ABSTRACT:In this study, changes of pH, ionic (Na + , K + , Ca 2+ , and Mg 2+ ), biochemical (total protein, glucose, and cholesterol) compositions of seminal plasma, sperm motility traits (percentage of motile spermatozoa and sperm movement duration), and sperm production characteristics (sperm volume, spermatocrit, and sperm density) were studied in Caspian roach, Rutilus rutilus caspicus, during spawning migration. Sperm of 10 males was collected three times during the spawning migration (in February, March, and April). The results showed that sperm motility parameters (percentage of motile spermatozoa and sperm movement duration) changed significantly (P < 0.05) during the reproductive season, but sperm density, spermatocrit, and sperm volume did not show significant differences during spawning migration. Analyses performed at each sampling time (February, March, and April) showed significant differences (P < 0.05) in calcium, magnesium, potassium, and cholesterol, whereas there were no significant changes in Na + , pH, total protein, glucose, and cholesterol.
