南极洋枪鱼（Dissostichus mawsoni）是广泛分布于南大洋尤其是海冰覆盖区的重要渔业物种。了解鱼类的分布和生命周期，包括卵和幼体的运输和存活，对于渔业的评估和可持续管理至关重要。然而，由于冬季原位观测的困难，缺乏有关毛氏杜在这里，我们通过粒子跟踪研究，利用卫星获得的东南极地区的海洋表面速度，研究了鱼卵和幼虫的运输途径，其中包括重要的D. mawsoni栖息地和探索性渔业。我们的研究结果表明，从大陆坡释放的颗粒更有可能被成功地运送到合适的定居地比那些从BANZARE银行（南部地区的Kerguelen高原），这是位于更北，并已被假设为一个潜在的产卵场福特。这项研究表明，成功的源-定居连接与海洋再循环，并建议在东南极地区的重要定居区福特. mawsonilarararthritis。
The Antarctic toothfish (Dissostichus mawsoni) is an important fishery species widely distributed in the Southern Ocean, especially in areas covered by sea ice. Understanding fish distributions and life cycles, including the transport and survival of eggs and larvae, is essential for the assessment and sustainable management of the fishery. However, owing to difficulties with in situ winter observations, information on the early life stages ofD. mawsoniis lacking. Here, we investigated the transport pathways of fish eggs and larvae through a particle tracking study, using satellite‐derived ocean surface velocities in the East Antarctic region, which includes importantD. mawsonihabitats and exploratory fisheries. Our results indicate that particles released from continental slopes are more likely to be successfully transported to suitable settlement grounds than those released from the BANZARE Bank (the southern region of the Kerguelen Plateau), which is situated further north and has been hypothesized to be a potential spawning ground forD. mawsoni. This study demonstrates successful source–settlement connections in relation to ocean recirculation and suggests important settlement regions forD. mawsonilarvae in the East Antarctic region.
