Investigation of Membrane Permeability of Carp Spermatozoa for Water Molecules
The fundamentals of a photometry method for determination of membrane permeability of some fish spermatozoa for water molecules are presented. Osmotic tolerance of carp spermatozoa membranes was studied using EPR-spectroscopy and photometric analysis methods. It was shown that carp spermatozoa look like the ideal osmometers in their reaction on media of different osmolarity. The value of membrane permeability of carp spermatozoa for water molecules was determined. Data obtained can be used in cryobiology for creating cryoprotective media and regimes of fish sperm cryopreservation.
