With eggs and children artemia were detedcted using nested-PCR. WSSV positive products could be detected in artemia, and DNA sequence of the product accords with the designed specific amplified one according to sequence analysis. The positive rates of wild brine shrimp and filial generation were 58% and 43%, respectively. However, it seems to be no regularity between parents and filial generations positive results. It may not judge whether WSSV could vertically transmit in artemia or not.
