| 5 | Oceanographic Condition in the Distribution Areas of Anchovy Engraulis Japonicus in the Yellow Sea and East China Sea显示文摘Based on the data obtained from the cooperative surveys by China and Norway from 1984 to 1994, this paper deals with the hydrographic characteristics of didribution areas of anchovy in the Yellow Sea and East China Sea from November to May. The relationships between distribution of anchovy and hydro-graphic environment are also analysed in this paper. The main research findings are briefly given below. (1) From November to March, the water temperature continually decreases and meanwhile the dense areas of anchovy move from north to south. The high schooling areas of anchovy are mainly distributed in the warm of cold front areas with temperature of 11-13℃. (2) In November and December, the Yellw Sea cold water-mass exists roughly between 50m depth and sea bottom. The thermo-balocline is approximately located at the 30 ~ 50m depth and the anchovy is usually distributed above the thermo-halocline In January and March, the Yellow Sea cold watermass disappears and the fish schools are distributed at the | Chen Jufa and Ma ShaosaiYellow Sea Fisheries Research Institute, CAFS, Qingdao 266071 | 1999 | Marine Science Bulletin1999，1，1： | 0 |
