The genetic structure of three stocks (K, H and S) of Penaeus chinensis was detected by RAPD method which useed 41 random oligonucleotide primers with 10 bases. Stock K was from the spawning stock of the western coastal waters of the Korea Peninsula, H was from the Huanghai Sea—Bohai Sea stock and S was from the health cultured stock in Jimo, Shandong Province, China. Three genetic markers, F-02 540, OPN-13 800 and OPN-20 2200, which could differentiate the three different stocks, have been reported. The basic data for marker assisted selection (MAS) on genetic breeding of Penaeus chinensis are provided.
