Popis:	When motility of spermatozoa of Cottos gobio was initiated with distilled water, the motility rate decreased to 0% within 1 min, and significant signs of osmotic alterations were observed at the end of the motility period. By contrast, in 50 mmol 1−1 NaCl solution, the motility rate persisted for 120–140 min. In both distilled water and in 50 mmol 1−1 NaCl solution, the main swimming type of spermatozoa was linear motion during the whole motility period. The initial swimming velocity (50.0 ± 2.1 μm s−1) measured 10 s after motility initiation was similar in both distilled water and in 50 mmol 1−1 NaCl solution. In distilled water, the velocity decreased to
