| Abstract: |
There exists obvious difference in recapture rate of tagged shrimp in various sea areas and years in autumn season, but the majority of them (98%) are recaptured in the releasing year. Although the main portion of each shrimp group in the Bohai Sea has separate distribution area, they intermingle in autumn season to search for food, thus forming a principal fishing ground located in the central Bohai Sea.
Those shrimps wintering in south-central portion of the Huanghai Sea are generally divided into two populations. One is called the Korean population, inhabiting along the western coast of Koera, which is less in abundance and smaller in shrimp size; and the other is called the Chinese population, inhibiting along the Bohai Sea coast and the Huanghai Sea coast of China, which is richer in abundance and larger in shrimp size. The spawning grounds of the latter extend throughout the Bohai Sea and off the Huanghai Sea coast of China, from the Yalujiang Estuary area in the north to the coastal waters of Haizhou Bay in the south, and its principal spawning grounds are located in numberous esturine waters along the Bohai Sea coast. |
