Growth and survival rates (specific growth rate -SGR; survival rate -S) of Barbus barbus L. were recorded in captivity during three years from the larval period (final body weight -W = 0.2 ± 0.03 g; SGR = 13.6 ± 1.1%/day and cumulative survival -S = 76.0 ± 2.5%) to the first reproductive season (W = 62.55 ± 13.5 g; SGR = 0.89 ± 0.05%/day; S = 59.3 ± 1.5%). Final body size and SGR were compared between both sexes. Females reached the significantly higher growth rate (SGR = 0.84 ± 0.01%/day) compared to males (SGR = 0.77 ± 0.01%/day). Early puberty was observed in 17 and 32 months old males and females, respectively. Multi-stripping activity was found out in both sexes during the first reproductive season. In total, 20%, 25.8%, 30.3%, 14.6% and 9% of females were stripped once, twice and three, four and five times, respectively. But all males produced sperm during the entire reproductive season. The highest and the lowest egg production was recorded in the middle (April) and at the beginning (March) of the reproductive season (2155 ± 925 vs. 1279 ± 298 eggs per stripping). The highest and the lowest sperm production was observed at the beginning (March) and at the end (May) of the reproductive season (7.9 ± 0.08 × 10 9 vs. 1.9 ± 0.06 × 10 9 per stripping).

“…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 sea urchin, as well as in humans, Mg 2+ has been found to increase viability of spermatozoa in dose-dependent manner (Dawson et al, 1998). Enhancing effect of Mg 2+ ions of seminal plasma on motility of spermatozoa was also found, among others, in fish (Hajirezaee et al, 2010;Bozkurt et al, 2011).…”

In domestic fowl (Gallus gallus f. domestica), monitoring of both quantitative and qualitative parameters of ejaculates is an indispensable precondition of successful artificial insemination; on the basis of the obtained results it is then possible to select the individuals that produce sufficient amounts AbstRAct: Ejaculates and blood plasma were sampled from cocks of three laying lines: Barred Plymouth Rock (BPR), Sussex Light (SU), and Rhode Island Red (RIR). Ejaculates and blood plasma were sampled four times during the laying period of hens. The following ejaculate parameters were determined: sperm motility, concentrations of sperm cells, ejaculate volume. Sperm morphology was examined. In the blood samples, concentrations of glucose, cholesterol, creatinine, calcium, phosphorus, and magnesium were analysed. The motility of spermatozoa of the cocks was 47.0% (BPR), 47.7% (RIR), and 48.3% (SU), respectively. The highest volume of ejaculate was found in BPR line (0.66 cm 3 ), the lowest one in SU line (0.46 cm 3 , P ≤ 0.01); the highest sperm concentration was in SU line (2.46 × 10 6 /mm 3 ), the lowest one in RIR line (1.96 × 10 6 /mm 3 , P ≤ 0.01). The number of morphologically abnormal sperm cells was similar in all lines − 47.0% BPR, 47.7% RIR, and 48.3% SU, respectively. In general, the occurrence of defective spermatozoa was high in all three lines; the most frequent were tail defects (from 20.3 to 29.7%), while sperm cells with developmental anomalies were less frequent (only 0.3 to 0.4%). Calculated phenotypic correlation between sperm motility on the one hand and the occurrence of defective sperm cells on the other was negative (r p = −0.28, P ≤ 0.01), as well as the correlation between sperm motility and sperm numbers, and between sperm motility and ejaculate volume (r p = −0.28, P ≤ 0.01 and r p = −0.31, P ≤ 0.01, respectively). Negative correlations were found between the level of magnesium in blood plasma and numbers of morphologically defective spermatozoa in the ejaculate, defective heads and defective connecting pieces (r p = −0.33, P ≤ 0.01; r p = −0.23, P ≤ 0.05; and r p = −0.26, P ≤ 0.05). Level of magnesium was positively correlated to sperm motility (r p = 0.26, P ≤ 0.05). However, positive correlations existed between concentration of glucose in blood plasma of cocks and numbers of morphologically defective spermatozoa in sampled ejaculates (r p = 0.27, P ≤ 0.01). Our finding is in accordance with the results found in mammals and other animals, and it shows an important role of magnesium as a key contributor to the quality of ejaculate in aviary species, in our case in laying lines of domestic fowl (Gallus domesticus).
