摘　　要：day serial near-bottom currents (at 20cm over Sea bottom) were measured in the northwest suitable breeding area near Lingshan Dao Island in order to study the potentials for the breeding environment. Statistical analysis is made for current speed frequency distribution besides harmonic analysis for these current data. The results show that the near-bottom current speeds mainly concentrate on the range of 6- 15 cm/s at frequency of 47 percent, the cumulative frequency at 25 cm/s reaches 86 percent, and maximum speed measured is 48 cm/s.day serial near-bottom currents (at 20cm over Sea bottom) were measured in the northwest suitable breeding area near Lingshan Dao Island in order to study the potentials for the breeding environment.
