    Abstract During evolution, the fish adopted versatile spawning tactics, which allowed them to use sperm competition effectively and prevent fertilization by inappropriate male gametes. Ovarian fluid (OF) affects spermatozoa performance in several fish species, as shown mainly in salmonids, and likely contributes to their reproductive tactics. Common carps utilize different spawning behavior compared to salmonids, which is accompanied by specific interactions of male gametes and maternal fluids, as observed in this study. The presence of common carp OF in the activation medium caused the decrease of spermatozoa velocity and altered the motility pattern from straightforward motility observed in the water to the hyperactivation-like tumbling in a swimming medium complemented by 50% OF. The chemotactic test (microcapillary sperm accumulation test) showed a significant response of carp spermatozoa to the OF. The attraction phenomenon depended on the presence of external calcium ions: the spermatozoa lost the ability to react to the attractant if the Ca²⁺ was absent in the activating medium. The carp spermatozoa were responsive to “osmotaxis”. Thus, the environmental conditions that accompany the encounter of gametes, particularly the presence of OF, significantly affect the performance of male gametes in common carp, which is in line with their spawning behavior.

    Abstract Synthetic pyrethroid pesticide is commonly used in agricultural activities in the Black Sea region during reproduction period of turbot. In this sense, in vivo and in vitro studies have shown that cypermethrin (CYP) could be one of the environmental factors affecting decreasing turbot stocks. In this study, effects of in vivo and in vitro administration of CYP, a synthetic pyrethroid, on sperm kinematics motility (MOT), progressive motility (PM), curvilinear velocity (VCL), straight line velocity (VSL), average path velocity (VAP), linearity (LIN), straight line velocity (STR), amplitude of lateral head (ALH), beat cross frequency (BCF), oxidative stress biomarkers malondialdehyde (MDA), reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and lipid peroxidation (LPO) and also histopathological alterations in gonads were investigated in spermatazoa of turbot (Schopthalmus maximus). Broodstock was supplied from culture origin and used in spawning season, additionally, two (0, 0.187 and 0.218 ppb) and three (0, 1.025, 2.05 and 4.1 ppb) different CYP concentrations were performed for in vivo and in vitro studies, respectively. In vivo and in vitro studies, significant reductions were found in sperm MOT, PM, VCL, VSL, VAP, LIN, and ALH properties depend on the increase in CYP concentrations (p < 0.05). Besides, activities of GSH, GPx, SOD, and CAT increased. In terms of histological alterations, no difference was observed among groups (0, 0.187 and 0.218 ppb) in the maturity stage of the germ cells. According to obtained results, sperm kinematics was affected significantly with increased the dose levels of CYP (p < 0.05).

    Abstract In this study sperm characteristics (sperm volume, sperm volume per kg fish, spermatocrit, sperm concentration, pH, and sperm motility) of wild‐caught and hatchery‐reared turbot (Scophthalmus maximus), originated from the Black Sea population, were assessed. In this regard, two different trials were conducted. On the Trial‐I, sperm characteristics of wild‐caught and hatchery‐reared turbot (4‐, 7‐, and 10‐year‐old) were comparatively investigated during the spawning season (May), on the Trial‐II, monthly variations of sperm characteristics of hatchery‐reared turbot (4‐year‐old) were investigated. On the Trial‐I, a positive correlation between body weight and sperm volume was recorded. Significant differences were noted in sperm volume, and sperm concentration, however, there was no significant difference between the groups in terms of sperm volume per kg of body weight, spermatocrit, and pH. The sperm motility showed a significant decrease after the 15 minutes post‐activation in all the specimens. The active spermatozoa rate of the wild‐caught turbot was 44% at 15 minutes post‐activation, whereas it was 16%, 13%, and 64% for 4‐, 7‐, and 10‐year‐old turbot, respectively. The average motility duration of the wild‐caught turbot spermatozoa was significantly longer compared to hatchery‐reared turbot despite having a comparatively lower initial motility rate than hatchery‐reared turbot. On Trial‐II spermiation duration of hatchery reared Black Sea turbot was determined as 6 months, starting from February until the end of July. The highest and the lowest sperm volume, and sperm volume per kg were recorded in June and July, respectively. Significant differences were determined between the months in terms of sperm volume per kg, sperm volume, spermatocrit, and sperm concentration, however, the pH was similar. These results demonstrate the sperm characteristics of wild‐caught and hatchery‐reared Black Sea turbot were different in the spawning season (May) and the potential spermiation season was between February and July.
