“…Previous studies have shown a larger spermatozoa nucleus in Eurasian perch (1.9 × 1.8 µm) (Lahnsteiner et al, 1995) compared to that of pikeperch (1.6 × 1.3 µm) (Lahnsteiner and Mansour, 2004), and the present study shows similar dimensions (1.8 × 1.6 µm). The minimal difference observed between the present study and that of Lahnsteiner and Mansour (2004) might be related to inter-individual differences as reported previously Psenicka et al, 2008;Hatef et al, 2011). Midpiece in pikeperch was found to be located lateral to the nucleus, in agreement with Lahnsteiner and Mansour (2004), while in Eurasian perch it is located at the base of the nucleus where the flagellum originates (Lahnsteiner et al, 1995;Hatef et al, 2011).…”

The present study and that of Lahnsteiner and Mansour (2004) showed similar ultrastructure of centrioles consisting of nine triplets of microtubules, but the organization of centrioles seems to differ between Eurasian perch and pikeperch.…”

“…The proximal centriole was inclined to the distal centriole under the angle of 90 or 110 o in pikeperch (Lahnsteiner and Mansour, 2004; the present study), but the angle was 90 o in Eurasian perch (Lahnsteiner et al, 1995;Hatef et al, 2010b). One or 2 mitochondria were previously reported in Eurasian perch (Lahnsteiner et al, 1995;Hatef et al, 2011), but 2-4 mitochondria were observed in the present study. In both species, cytoplasmic channel was observed between the flagellum and midpiece.…”

“…A lateral fin-like projection was observed in pikeperch, but it was not reported in Eurasian perch (Lahnsteiner et al, 1995;Hatef et al, 2010b). This structure was previously reported in sturgeon (Psenicka et al, 2008;Hatef et al, 2011) and pike, Esox lucius (Alavi et al, 2009b).…”

“…At 120 s post-activation, spermatozoa motility decreased from 36-43% (0 h storage) to 0-5% (48-hour storage of sperm), but sperm velocity remained unchanged (11-13 µm/s at 0 h and 10 µm/s after 48 h). Decrease in spermatozoa motility and velocity has been frequently documented in fish species including common carp, Cyprinus carpio (Saad et al, 1988), halibut, Hippoglossus stenolepis (Billard et al, 1993), turbot, Psetta maxima (Chereguini et al, 1997), tench, Tinca tinca (Rodina et al, 2004), and Eurasian perch (Hatef et al, 2011). These decreases have been attributed to damage of spermatozoa ultrastructure and decrease of ATP content Hatef et al, 2011).…”

Spermatozoa morphology, ultrastructure, and spermatozoa motility traits were studied in pikeperch (Sander lucioperca) after activation in various media (AM 1 -45mM NaCl, 5mM KCl, 20mM Tris, pH 8.5; AM 2 -100mM sucrose, 20mM Tris, pH 8.5; AM 3 -100mM sucrose, 1mM CaCl 2 , 20mM Tris, pH 8.5) during a 48-hour storage period. The spermatozoon was acrosomeless and differentiated into a spherical nucleus (head), midpiece, and flagellum. The nucleus length and width measured 1.83 ± 0.03 and 1.63 ± 0.02 mm, respectively. The midpiece was located laterally to the nucleus and possessed proximal and distal centrioles and 2-4 mitochondria. Flagellar length was 33.2 ± 0.90 µm, and a pair of lateral fin-like structures projections was observed. The axoneme consisted of nine peripheral doublet microtubules and a single central pair. After a 24 h storage in all activation media at all sampling times post-activation (15, 45, 90, and 120 s), spermatozoa motility was significantly decreased. Spermatozoa were motile after the 48-hour storage at all sampling times post-activation only in AM 3. After the 48-hour storage, no motile spermatozoa were observed in AM 2 and AM 1 at 90 and 120 s post-activation, respectively. Differences in spermatozoa velocity varied with activation medium during storage. After the 48-hour storage in AM 1 and AM 2, decrease of spermatozoa velocity at 15 s post-activation was observed, while in AM 3, velocity was decreased only after the 48-hour storage. Pikeperch spermatozoa morphology and ultrastructure was found similar to that of most freshwater teleosts, with differences in the arrangement of midpiece, number of mitochondria, and position of centrioles. Viable pikeperch sperm was observed after the 48-hour storage. Motility of spermatozoa was improved by addition of Ca 2+ to the activation medium, where higher spermatozoa velocity was observed.

Spermatogenesis was investigated in the Adriatic sturgeon, Acipenser naccarii, by light and electron microscopy. The testis of the unrestricted type had a germinal compartment composed of lobules containing germ cells and Sertoli cells, and separated by a basal lamina from the interstitial compartment, in which Leydig and myoid cells were detected for the first time in Acipenseridae. Spermatogenesis occurred in spermatocysts produced when Sertoli cells became associated with type A spermatogonia of subsequent generations, which produced a clone of synchronized aligned spermatogonia. In primary spermatocytes at zygo-pachytene stage, the large spherical nucleus contained synaptonemal complexes. The smaller secondary spermatocytes were ovoid with a central round nucleus and scarce cytoplasm. Spermatids were interconnected by cytoplasmic bridges until early spermiogenesis. Chromatin initially condensed as long, twisted, and nonhomogeneous fibers and finally as a compact structure made of thick filaments.Early spermatids showed the flagellum, the primordia of centriole complex and of "implantation fossa," followed by the acrosomal vesicle formed by Golgi complexes and a fibrous body associated to centriole complex. The spermatozoan head had 10 postero-lateral projections and a trapezoidal nucleus, a cylindrical midpiece with six to eight mitochondria, the centriole complex, and a "9 + 2" flagellum with a pair of lateral fins. Three helical endonuclear canals crossed the nucleus from the acrosome base to the implantation fossa; their spiralization and that of chromatin fibers suggest a spiral twisting of the nucleus during spermiogenesis. The Sertoli cells performed phagocytosis of degenerating spermatids and spermatozoa. Significant interindividual differences were detected in most morphological parameters of spermatozoa. Data on spermatogenesis in A. naccarii and morphometric measurements on mature spermatozoa provide information about the reproductive biology of the species useful not only for phylogenetic studies but also for evaluation of sperm quality for artificial reproduction projects and restocking of this and other critically endangered sturgeon species.
