“…Perhaps these differences result from differing sex reversal protocols; Kobayashi et al [7] used 17a-methyltestosterone, and we used 11b-hydroxyandrostenedione. This suggestion is supported by the results of our recent studies reporting that our protocol is highly effective for the production of high sperm motility of sex-reversed female rainbow trout [4,5].…”

“…Fish from autumn spawning (December 11, 2013) were used in the experiment. Milt from sex-reversed females was obtained post mortem by cutting testes and gently squeezing through a double-layer gauze to remove any testicular tissue [4,5].…”

“…The motility parameters of the spermatozoa were measured and analyzed using a Hobson Sperm Tracker (Hobson Vision Ltd., Baslow, UK) as previously described [4,5,9]. Video recordings (two replicates per sample) were made using a microscope with a 10-negative-phase objective and a Sony CCD black-and-white camera (SPT-M108CE).…”

“…For this reason, milt of sex-reversed females resembles testicular milt instead of milt of normal males. Compared with normal milt, milt of sexreversed females is characterized by a higher sperm concentration and higher concentrations of seminal plasma proteins, but lower values of sperm motility [4,5]. These differences reflect the lower quality of testicular milt.…”

“…composition of seminal plasma [22]. Similar seasonal changes in sperm motility have also been observed in 15 SR females [30]. In this regard, it is likely that the composition or/and amount of TAC is related to sperm The sperm samples obtained from SR females, due to taken from gonads, have more spermatozoa than the Also, it is hard to obtain FTIR spectra without KBr cover due to the large water content of seminal plasma.…”

This study aims to describe seminal plasma characteristics, detect changes during and between two consecutive spawning seasons (SS), and compare plasma features between two important South American fish species. Prochilodus lineatus and Brycon orbignyanus sperm was collected over two (SS1; SS2). Each season was divided into first and second sampling periods (P1; P2). Thus, the four experimental periods were referred to as SS1P1, SS1P2, SS2P1, and SS2P2. Seminal plasma was analyzed for osmolality, pH, and Na+, K+, and Ca2+ concentration. Additionally, sperm concentration, motility rate, and velocities (curvilinear = VCL; straight line = VSL) were determined and correlated with plasma features. In P. lineatus, plasma osmolality was lower in SS1P2, pH was higher in SS2P2, Na+ was higher and K+ and Ca2+ were lower in SS2P1 compared with other experimental periods. Positive correlations were observed between motility and plasma osmolality, motility and Na+, and VCL and Na+. In B. orbignyanus, plasma osmolality was higher in SS2P1 and SS2P2 and K+ concentration was higher in SS1P1 compared with other experimental periods; no correlation was observed. Seminal plasma parameters change during SS; therefore, the composition of a sperm extender and artificial fertilization methods should be adapted to maximize fertilization rates.
