Age and growth of blue antimoraAntimora rostratawere examined for the first time in the waters of Kerguelen and Crozet Islands (southern Indian Ocean, sub-Antarctic). The longline catches were represented by fish ranging from 39 to 72 cm in total length with weights between 400 and 3310 g, aged 16– 41 years. A minimum age of 16 years was observed in a fish 39 cm long, while a maximum age of 41 years was recorded for an individual of 70 cm in length and 3310 g in weight. The age classes with the greatest numbers were represented by fish aged 34 years (9%), 28 years (9%) and 29 years (8%), which together accounted for 26% of the total catch. The blue antimora in the southern Indian Ocean shows similar growth rates to those of individual fish from the Ross, Lazarev and Weddell Seas and southeastern Greenland, which may indicate the population unity of the species within the Antarctic and sub-Antarctic waters or similar habitat conditions in these areas.

来自南印度洋 Kerguelen 和 Crozet 群岛的Antimora rostrata（Moridae、Gadiformes、Teleostei）的年龄和生长

蓝色antimora的年龄和生长尖顶金龟子首次在 Kerguelen 和 Crozet 群岛（印度洋南部，亚南极）水域进行了检查。延绳钓捕捞的鱼的总长度在 39 到 72 厘米之间，重量在 400 到 3310 克之间，年龄在 16 到 41 岁之间。一条 39 厘米长的鱼的最小年龄为 16 岁，而一条长 70 厘米、体重 3310 克的个体的最大年龄为 41 岁。数量最多的年龄组是 34 岁（9%）、28 岁（9%）和 29 岁（8%）的鱼，它们合计占总捕捞量的 26%。印度洋南部的蓝色antimora的生长速度与罗斯海、拉扎列夫海和威德尔海以及格陵兰岛东南部的个体鱼类相似，
