    Ultrastructure of sterlet Acipenser ruthenus L., 1758 sperm was examined by scanning and transmission electron microscopy, which allowed us to use various methods for visualizations of different part of sterlet spermatozoa. The present set of results represents the first study about the fine structure and morphology of sterlet spermatozoa. Comparison between the present and previous studies of morphology of sturgeon spermatozoa confirmed large inter and/or intra-specific differences that could be of substantial taxonomic value.

    Ultrastruktura spermií jesetera Acipenser ruthenus L., 1758 byla zkoumána pomocí transmisní a skenovaní elektronové mikroskopie a dalších metod, které umožnily pozorování různých částí spermií. Porovnání mezi prezentovanými a předchozími morfologickými studiemi potvrdilo velké inter a intra-specifické rozdíly, které mohou mít rozhodující taxonomickou hodnotu.
