| Description
| - Čínský jeseter (Acipenser sinensis Gray 1835) je endemickým jeseterem žijícím v řece Yangtze v Číně. V této práci se studovala ultrastruktura a morfologie spermií pomocí elektronové mikroskopie a kryořezů. Spermie mají elongovanou hlavičku, jasný akrosom, oblast jádra a bičík v síle 4.48, 33.3 a 37.8 μm. V akrosomu byla nalezeny granulární substance a aktinová filamenta. Bylo detekováno tři až pět endonukleárních kanálů. Ve srovnání s jinými jeseterovitými druhy, předložená data ukazují na blízký evoluční vztah Chinese sturgeon a bílého jesetera (Acipenser transmontanus Richardson 1836). (cs)
- Chinese sturgeon (Acipenser sinensis Gray 1835) is an endangered anadromous sturgeon inhabiting the Yangtze River, China. Here, the ultrastructure and morphology of spermatozoa was studied using transmission and scanning electron microscopy with a cryo-holder. The spermatozoon consisted of an elongated head with a distinct acrosome and nucleus region, a midpiece and a flagellum. The mean length of the head and midpiece, the flagellum and total length of spermatozoon were 4.48, 33.3 and 37.8 μm, respectively. The nucleus was an elongated trapezoid shape with anterior (acrosome) end narrower than the posterior. Granular material and an actin filament were observed within the anterior acrosome. Three to five endonuclear canals were present. The midpiece was eudipleural along its longitudinal axis. Compared to other sturgeon species, data from the present study suggest a more recent evolutionary linkage between Chinese sturgeon and white sturgeon (Acipenser transmontanus Richardson 1836).
