Identification of Hybrid Sturgeon (<i>Acipenser baerii</i> × <i>Acipenser schrenckii</i>) from Their Parents Using Germplasm. [PDF]

open access: yesAnimals (Basel)
The hybrid sturgeon Acipenser baerii × A. schrenckii is the most widely cultured commercial sturgeon in China. However, its morphological similarity to the parental species frequently leads to misuse of germplasm in the breeding process, resulting in a decline in the quality of the sturgeon production.
