Abstract :

Abstract[1] Given the importance of sturgeon species and the sharp decline in reserves, recognition causes of mortality in this fish, to implement appropriate strategies, in order to cope with eventual mortality appears to be essential. Therefore, over a period during 2010 to 2012 causes of mortality Huso huso and Acipencer nudiventris in the sturgeon culture center in Mazandaran province were studied. During this period study, 2 sporadically mortality with symptoms such as: hemorrhage in gills, visceral organs, base of fins and ventral surface was observed. The results of bacterial culture and biochemical tests in both cases, confirmed the presence of Aeromonas hydrophila, necessary practices was took, that leading control of mortality and disease. * Corresponding Authors; Email: [e-mail]
