Ultrastructural studies (TEM) on Hucho hucho (L.) spermatozoa revealed lack of acrosome and eccentric situation of the flagella in relation to the head and the middle piece. The relatively small middle piece, with characteristic mitochondrial collar, is separated from the flagella by a cytoplasmic canal. Axial part of the flagella is formed by a microtubular complex of the formula 9+2. Apart from different size of various elements, ultrastructure of Hucho hucho spermatozoa is similar to that in other salmonids.
