Abstract

Abstract

A grid of 22 stations,giving a broad geographic coverage of the Bohai Sea and the Bohai Straits was selected.Undisturbed sediments were collected from sampling stations during cruises in July 1997,in September/October 1998 and again in April/May 1999.Based on the the results of Juario,the aver ag e biomass 0.404 g/(m²·a)o f meiofauna(including nematode,Harpacticoida,bivalve larvae,Polychaeta and Kinor hyncha)in the Bohai Sea is given and accounts for 4.5% of the macrofauna in the Bohai Sea.The horizontal distribution of the biomass of meiofauna shows that it was higher at the stations of middle east part of the Bohai Sea and the strait in 1998 and 1999 cruise and it decreased at the stations near the straits mouth and increased at Station B1 in 1999 cruise.The annual average production in the Bohai Sea is 3.636 g/(m²·a),calculating in term of the formula P=9B. Compared with the biomass of other sea areas in the world,the biomass of the Bohai Sea is hear but slightly low. The individual average dry weight of nematodes given by different authors is analysed.
