Comparative analysis of blood and seminal plasma composition of Persian sturgeon, Acipenser persicus

Abstract

Sturgeon are currently generating interest, as most belong to endangered or critically endangered species and are listed in The International Union of Conservation of Nature Red List of Threatened Species. Blood and seminal biochemical parameters are important aspects in the management and conservation of endangered species such as Acipenser persicus. In this research, comparison of blood and seminal plasma compounds including sodium (Na+), chloride (Cl-), potassium (K+), calcium (Ca++), magnesium (Mg++), total protein, glucose, cholesterol and triglyceride in Persian sturgeon were studied. Results indicated that the concentrations of all parameters of blood plasma were significantly (P<0.05) higher than seminal plasma except Potassium. Differences found can be ascribed to the existence of a blood-testis barrier.
