根据2004年4、6、9月和12月在黄海南部和东海中北部(27°00′～34°00′N、122°00′～127°00′E)进行的渔业资源大面定点底拖网调查资料,以相对资源密度指数作为指标值,分析了黄鮟鱇的时空分布特征.并利用GAM模型,分析了黄鮟鱇数量分布与经纬度、水深、底温和底盐等环境因子的关系.结果表明:黄鮟鱇主要分布在黄海南部和东海北部海区, 4个季节的分布范围有明显不同,以春季为最大,冬季最小;黄鮟鱇适宜底温、底盐和水深范围分别为11～14 ℃、33.5～34.5和40～90 m;根据黄鮟鱇分布的底温范围,推断黄鮟鱇为冷温性鱼种.

Based on the data taken from bottom trawl fishery resources survey in the south Yellow Sea and the middle and north East China Sea(27°00′-34°00′N,122°00′-127°00′E)during 2004, the paper deals with the quantity distribution of Lophius litulon in East China Sea. Using Generalized Additive Models (GAM), we examined its' relationship with environmental factors such as depth, temperature and salinity. The results showed that Lophius litulon mainly distributed in the south Yellow Sea and the north East China Sea. There was obvious difference in distribution scope among four seasons, in April the area was the widest, while in December the least. By means of GAM, the calculated optimal scale of temperature, salinity and depth were 11-14 ℃,33.5-34.5 and 40-90 m, respectively. According to the range of water temperature Lophius litulon preferred, we presumed that Lophius litulon would be a cold-temperate species.
