Survey on Acipenser persicus Populations by use of the Electrophoretic Technique and Morphological Characteristics

For identifying the populations of the Acipenser persicus (Persian sturgeon) a survey were done by use of the electrophoretic technique and also morphological characteristics. The matrix was Acetate cellolus. 5ml blood from each gill arch were obtained and separated serum from blood. Separation of proteins were done, using a voltage of 180 volt during 15 minutes. After separating the solution proteins, the bands were stained by ponceau-s, Decolouring of plates was done by Acetic acid 5% during three steps. Scanning of the plates was done by densitometer with the wave length of 525 nm. Several genetic variations observed in the electrophorograms of samples. It seems that population of some localities can be characterized as a genetically distinguishable unit. Morphological differences observed between the fish which located in Sephid Rud region and Gorgan region, like the eye diameter and head height. The mean of eye diameter in Sephid Rud population was 20.16 mm and in Gorgan popu.....
