Study on the propagation possibility in reared great sturgeon, Huso huso by GnRH synthetic hormone for production of fingerling
This study was carried out in the International Sturgeon Research Institute of Dr. Dadman during 2007–2011. A total of 24 beluga 7- year – old (Huso huso) including 8 males and 16 females were selected after morphological assay, biopsy and sexing based on histological routine methods and then stocke...
