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。
According to the large bottom point of fishery resources carried out in the southern Yellow Sea and the north-central part of the East China Sea in April, June, September and December 2004 (27 ° 00 ’~ 34 ° 00’N, 122 ° 00’ ~ 127 ° 00’E) Trawl survey data, the relative resource density index as an index value, analysis of the spatial and temporal distribution characteristics of the yellow grubs. By using the GAM model, the relationship between the distribution of yellow crabgrass and the environmental factors such as latitude and longitude, water depth, bottom temperature and bottom salt was analyzed. The results showed that: the main distribution in the South Yellow Sea and the northern part of the East China Sea, the distribution of the four seasons are significantly different, with spring the largest and the winter minimum; suitable for the yellow soleil, bottom salt and water depth range of 11 ~ 14 ℃ , 33.5 ~ 34.5 and 40 ~ 90 m, respectively. According to the distribution of the bottom temperature range, it is inferred that Pseudacus chinensis is cold-temperate species.
