Marine Ecological Journal| Summary: | Monitoring of the sperm activity of the Black Sea turbot (BST) Psetta maxima maeotica (Pallas) was carried out from the natural spawning populations from the Black Sea shelf southwest of the Crimean peninsula (Sevastopol region) in 2007 – 2010 for the first time. Experimental data on BST sperm motility revealed the high reproductive potential of males. Rather low concentration (1.5± 0.29x109 spermatozoa/ml) was compensated by high medium curvilinear speed 140 μm/sec with maximum 427 μm /sec. Highest activation of sperm by 18‰ sea water was observed during 10 – 40 min after activation, and duration of activity of 15-35% of spermatozoa with average speed 80 μm /sec was still observed 7 hrs after activation. Typical quota and spermatozoa speed were significantly higher (p ≤ 0.05) for BST males from 2010 spawning population in comparison with that of 2008. |
