“…In absence of experimental determination of viscosity, the viscosity of ovarian fluid was estimated as 8 times that of river water by analogy with values measured on trout ovarian fluid at 10°C (J.C., unpublished data). This value is close to those obtained by Rosengrave et al (2009b) at 15°C, considering that sperm movement occurs at low shearing rate (Brokaw, 1966). Therefore, a 40% ovarian fluid activation medium, as used in these experiments, leads to a viscosity value of 3.2 cP (0.0032 Pa s) relative to river water (at 11°C in our experiments).…”

This is related to changes in viscosity (Turner and Montgomerie, 2002), pH (Wojtczak et al, 2007) and/or ionic composition of activation media (Rosengrave et al, 2009b). Ovarian fluid has even been found to differentially enhance sperm based on genetic relatedness of mates (Gasparini and Pilastro, 2011;Butts et al, 2012a) or spawning origin (i.e.…”

Alternative reproductive tactics (ARTs) are prevalent in nature, where smaller parasitic males typically have better sperm quality than larger territorial guard males. At present, it is unclear what is causing this phenomenon. Our objective was to gain insights into sperm form and function by examining flagellar beating patterns (beat frequency, wave amplitude, bend length, bend angle, wave velocity) and biomechanical sperm metrics (velocity, hydrodynamic power output, propulsive efficiency) of wild spawning Chinook salmon ARTs. Ovarian fluid and milt were collected to form a series of eight experimental blocks, each composed of ovarian fluid from a unique female and sperm from a unique pair of parasitic jack and guard hooknose males. Sperm from each ART were activated in river water and ovarian fluid. Flagellar parameters were evaluated from recordings using high-speed video microscopy and biomechanical metrics were quantified. We show that ART has an impact on flagellar beating, where jacks had a higher bend length and bend angle than hooknoses. Activation media also impacted the pattern of flagellar parameters, such that beat frequency, wave velocity and bend angle declined, while wave amplitude of flagella increased when ovarian fluid was incorporated into activation media. Furthermore, we found that sperm from jacks swam faster than those from hooknoses and required less hydrodynamic power output to propel themselves in river water and ovarian fluid. Jack sperm were also more efficient at swimming than hooknose sperm, and propulsive efficiency increased when cells were activated in ovarian fluid. The results demonstrate that sperm biomechanics may be driving divergence in competitive reproductive success between ARTs.

“…In fish, several factors have been reported that regulate the composition of seminal plasma (Ciereszko, 2008;Alavi et al, 2008b). It has already been shown in the literature that there are several correlations between seminal plasma composition and sperm motility in some species: Salmo salar (Hwang and Idler, 1969), Cyprinus carpio (Kruger et al, 1984), rainbow trout (Lahnsteiner et al, 1998), Persian sturgeon, Acipenser persicus (Alavi et al, 2004), and Oncorhynchus tshawytscha (Rosengrave et al, 2009). Lahnsteiner et al (1996) reported a correlation between sperm motility and seminal plasma composition in bleak Alburnus alburnus, a cyprinid, and suggested that this correlation might indicate which components of the seminal plasma influence sperm motility.…”

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.

“…Seminal plasma produced by the sperm duct provides an ionic environment that maintains the viability of spermatozoa after their release from the testes [79]. It has been already shown in the literature that there are several correlations between seminal plasma composition and sperm motility in some species; Atlantic salmon, Salmo salar [72], common carp, Cyprinus carpio [66], bleak, Alburnus alburnus [74], rainbow trout, Oncorhynchus mykiss [80], Persian sturgeon, Acipenser persicus [81] and chinook salmon, Oncorhynchus tshawytscha [82]. In freshwater species, matured sperm need a hypo-osmotic shock for triggering initiation of sperm motility [29].…”

Motility is an important function of the male gamete, which allows sperm to actively reach and penetrate the female gamete in organisms with internal and external fertilization. Sexual activity of some fish is generally seasonal and fertilization is external. Sperm, once differentiated in the gonad, remain there completely quiescent until they are released into the external medium, which is either freshwater or sea water. Various parameters such as ion concentrations (K + , Na + , Ca 2+ ), osmotic pressure, pH, and temperature affect motility. In the present paper, we review the roles of these factors on sperm motility in the teleosts. Studying the effects of these factors on teleost sperm can help establish good activation and/or immobilizing media for improving either artificial fertilization or cryopreservation.
