Semen characteristics in Acipenser persicus in relation to sequential stripping

Semen characteristics in Acipenser persicus in relation to sequential stripping By Sayyed Mohammad Hadi Alavi1, Jacky Cosson2 and Rezvan Kazemi3 Research Institute of Fish Culture and Hydrobiology, University of South Bohemia, 389 25 Vodnany, Czech Republic; 7009 CNRS, Université Pierre et Marie Curie, Villefranche-sur-Mer, France; 3International Sturgeon Research Institute, P.O.Box, 41635-3464, Rasht, Iran 2UMR 1 Summary Seminal plasma indices (osmolality and ionic composition), spermatozoa concentrations and sperm motility were studied in the Persian sturgeon, Acipenser persicus in order to use these semen biomarkers to measure performance in terms of sequential stripping effects.
