| 摘 要： | 根据 1997年 12月至 1999年 6月在南海北部陆架区海域进行的底拖网渔业资源调查的资料 ,统计分析了南海北部陆架区海域深水金线鱼性腺成熟期的组成及分布、季节性变化和水深变化规律。结果表明 ,南海北部陆架区海域深水金线鱼的产卵场位于广东沿海水深 6 0～ 15 0m海区 ,尤其是珠江口外海区的群体更为密集 ;该生殖群体的产卵期较长 ,且分布范围大 ,未见有显著性变化。

| Abstract: | Based on a one ear fishery resources investigation data of bottom trawl from December 1997 to June 1999, which included four seasons with nine voyages in continental shelf waters of the north of South China Sea, this paper analysed individual compositions and distributions of Nemipterus bathybius in gonadal maturity, and variations with season and water depth by statistical analysis. The results indicated that spawning ground lied in the coastal sea area of Guangdong with the water depth from 60 m to 150 m, especially in outside sea area of Zhujiang Estuary where spawning period was very long and spawning place have not obvious changes. |
