Abstract
International policy recently adopted commitments to maintain genetic diversity in wild populations to secure their adaptive potential, including metrics to monitor temporal trends in genetic diversity - so-called indicators. A national programme for assessing trends in genetic diversity was recently initiated in Sweden. Relating to this effort, we systematically assess contemporary genome-wide temporal trends (40 years) in wild populations using the newly adopted indicators and whole genome sequencing (WGS). We use pooled and individual WGS data from brown trout (Salmo trutta) in eight alpine lakes in protected areas. Observed temporal trends in diversity metrics (nucleotide diversity, Watterson's ϴ and heterozygosity) lie within proposed acceptable threshold values for six of the lakes, but with consistently low values in lakes above the tree line and declines observed in these northern-most lakes. Local effective population size is low in all lakes, highlighting the importance of continued protection of interconnected systems to allow genetic connectivity for long-term viability of these populations. Inbreeding (FROH ) spans 10%-30% and is mostly represented by ancient (<1 Mb) runs of homozygosity, with observations of little change in mutational load. We also investigate adaptive dynamics over evolutionarily short time frames (a few generations); identifying putative parallel selection across all lakes within a gene pertaining to skin pigmentation as well as candidates of selection unique to specific lakes and lake systems involved in reproduction and immunity. We demonstrate the utility of WGS for systematic monitoring of natural populations, a priority concern if genetic diversity is to be protected.

Abstract
The aim of this study was to evaluate the effect of both pure rainbow trout seminal plasma (RTSP) supplementation and RTSP-cysteine combination on cryopreservation success and post-thaw incubation resilience of ram semen in the nonbreeding season. For this purpose, different doses of RTSP (0%, 1%, 10%, and 15%) with or without cysteine supplementation were used for experiments. Ejaculates chosen for experiments were pooled and then divided into eight equal volumes for grouping (Control-ControlC, RTSP1-RTSP1C, RTSP10-RTSP10C, and RTSP15-RTSP15C). After cryopreservation, frozen-thawed semen samples were incubated for 5 hours at 37°C for determination of post-thaw incubation resistance. Motility, HOST, TUNEL, Rh123-PI, and CTC tests were performed at 0 hour and 3rd and 5th hours of post-thaw incubation to evaluate the efficacy of all experimental groups. The RTSP10 and RTSP10C groups were noted to provide the best protection on motility, plasma membrane integrity, DNA integrity, and mitochondrial function of cryopreserved ram semen. On the other hand, the best protection against cryo-capacitation was observed in RTSP15 and RTSP15C groups. The addition of cysteine was found to be effective when the higher (15%) or lower (1%) doses of RTSP were used, as well as for no use of RTSP.

Abstract
The present experiment aims to study the effects of dietary multi-strain probiotics on semen quality, seminal plasma compositions, and fertilization ability of male rainbow trout. For this purpose, a total of 48 broodstocks with an average initial weight of 1366.1 ± 33.8 g were divided into 4 groups and 3 replicates. Fish were fed with diets containing 0 (control), 1 × 109 (P1), 2 × 109 (P2), and 4 × 109 (P3) CFU probiotic kg-1 diet for 12 weeks. Results showed that dietary supplementation of probiotics significantly increased plasma testosterone level, motility time of spermatozoa, sperm density, and spermatocrit value in P2 and P3 treatments and Na+ level in P2 treatment compared to the control group (P < 0.05). The activities of aspartate aminotransferase and lactate dehydrogenase had significantly decreased in the P2 treatment compared to the control group (P < 0.05). No considerable variations were observed between control fish and treatment groups (P > 0.05) in semen biochemical parameters, percentage of motile spermatozoa, osmolality, and pH of seminal plasma. Based on the results, the highest fertilization rate (97.2 ± 0.9%) and eyed egg survival (95.7 ± 1.6%) were observed in the P2 treatment, and those values showed remarkable differences with the control group (P < 0.05). The results indicated that multi-strain probiotics have potential efficacy on semen quality and fertilization ability of rainbow trout broodstock spermatozoa.

Abstract
The objective of this study was to determine the optimum concentrations of rainbow trout seminal plasma (RTS) supplemented extenders for goat semen quality at post-thaw and after incubation. Five sexually mature Saanen goat (Capra aegagrus hircus) were used for semen collection. Pooled semen was diluted with soybean lecithin-based extender without RTS (control) or supplemented with different concentrations of RTS (1%, 2%, 4% or 8%), at a final concentration of 150 × 106 spermatozoon/ml. Sperm motility, plasma membrane functional integrity (HOST), damaged acrosome (PSA-FITC), mitochondrial activity (rhodamine123) and DNA integrity (TUNEL) were evaluated. Spermatological parameters were evaluated at post-thaw and after 6 hr incubation. RTS8 group preserved sperm motility, acrosomal integrity, plasma membrane functional integrity and mitochondrial function better than the control group (p < .05). The study demonstrated that RTS supplemented lecithin-based extenders have useful effects on goat spermatozoa. In addition, the results of the current study represented the positive effect of using 8% RTS supplemented extender.

Abstract
Motility analysis of spermatozoa relies on the investigation of either head trajectories or flagellum characteristics. Those two sets of parameters are far from being independent, the flagellum playing the role of motor, whereas the head plays a passive role of cargo. Therefore, quantitative descriptions of head trajectories represent a simplification of the complex pattern of whole sperm cell motion, resulting from the waves developed by the flagellum. The flagellum itself responds to a large variety of signals that precisely control its axoneme to allow activation, acceleration, slowing down or reorientation of the whole spermatozoon. Thus, it is obvious that analysis of flagellum characteristics provides information on the original source of movement and orientation of the sperm cell and presents additional parameters that enrich the panoply of quantitative descriptors of sperm motility. In this review, we briefly describe the methodologies used to obtain good-quality images of fish spermatozoa (head and especially flagellum) while they move fast and the methods developed for their analysis. The paper also aims to establish a link between classical analyses by computer-aided sperm analysis (CASA) and the descriptors generated by fish sperm flagellum analysis, and emphasises the information to be gained regarding motility performance from flagellum motion data.

Hormonal stimulation of carp is accompanied by changes in seminal plasma proteins associated with the immune and stress responses. J Proteomics 2019; 202:103369.

Abstract
Hormonal stimulation in common carp is a routine practice to enhance sperm production and control gamete maturation. This study aimed to compare the proteome of carp seminal plasma between control and Ovopel-induced males using two-dimensional differential in-gel electrophoresis. Ovopel induction increased sperm volume, total sperm count, seminal plasma osmolality, and pH and decreased seminal plasma protein concentration. In total, 36 spots were identified (23 up- and 13 downregulated), corresponding to 23 proteins differentially abundant in seminal plasma after Ovopel induction (p < .05; fold change 1.2). The majority of proteins were associated with the immune and stress responses including the transport protein (hephaestin), antiproteases (fetuin, α2-macroglobulin, TIMP2), complement components (C3, complement factor B/C2A), regulator of the coagulation cascade (plasminogen), modulators of the innate immune response, such as intelectin, ApoA and ApoE, and the cathepsin/cystatin system, and stress response (enolase1). In addition, hormonal stimulation seems to be related to the proteins involved in lipid metabolism, signal transduction, and tissue remodeling. Our results suggest that hormonal stimulation is not just concomitant with the hydration of testis but also induces the synthesis and secretion of seminal plasma proteins involved in sperm maturation and protection against stress induced by administration of the exogenous hormone. SIGNIFICANCE: It is well known that hormonal stimulation of male fish induces the final maturation of spermatozoa. However, molecular and biochemical basis underlying hormone-induced changes in semen is unknown at present. This study for the first time reveals, using proteomic approach, that hormonal stimulation in addition to hydration of testis is accompanied by significant changes in seminal plasma proteins related mainly to immune and stress response, lipid metabolism, signal transduction and tissue remodeling. These changes are associated with gene expression and synthesis and secretion of seminal plasma proteins by reproductive tissues. Overall, our results provide a framework for understanding the molecular mechanism responsible for hormonal stimulation in the reproductive tract of fish males.

Abstract
Proteomics and metabolomics are emerging and powerful tools to unravel the complex molecular mechanisms regulating reproduction in male fish. So far, numerous proteins and metabolites have been identified that provide us with valuable information to conduct a comprehensive analysis on seminal plasma and spermatozoa components and their functions. These analyses have allowed a better understanding of the blood-testis barrier functions, the molecular mechanisms underlying spermatogenesis, spermatozoa maturation, motility signaling, and competition as well as the mechanism of cryodamage to sperm structure and functions. To extend, proteins that undergo posttranslational modification, such as phosphorylation and oxidation in response to spermatozoa motility activation and cryopreservation, respectively, have been identified. Proteomic studies resulted in identification of potential proteins that can be used as biomarkers for sperm quality and freezability to enable the control of artificial reproduction, and to improve methods for long-term preservation (cryopreservation) of sperm. The different proteins expressed in the spermatozoa of neomales and normal males can also provide new insights into development of methods for separating X and Y fish sperm, and changes in the protein profiles in haploid and diploid spermatozoa will provide new perspectives to better understand the mechanism of male polyploidy. Overall, the knowledge gained by proteomic and metabolomic studies is important from basic to applied sciences for the development and/or optimisation of techniques in controlled fish reproduction.
