ABSTRACT Movement patterns of the Southern Rock Lobster Jasus edwardsii in Victoria, Australia were investigated from 8,533 tag-recapture events across a 20-year period (1992–2012). In total, 83% of lobsters were recaptured within 1 km of their tagging site and 93% within 5 km. While largely resident, elevated movements were observed within specific regions, with the overall direction of movement being from inshore to offshore areas. Movement was not impacted by lobster sex, size, or reproductive stage. The fishery for Southern Rock Lobster within Victoria is currently managed into two zones with separate total allowable commercial catches in each area. Given the high levels of site fidelity, our findings suggest that management of the resource at this spatial scale is appropriate and that consideration of significant movement between zones is not warranted in fishery stock assessment models.

澳大利亚维多利亚州南岩龙虾 (Jasus edwardsii) 运动模式的高水平现场保真度

摘要 从 20 年期间(1992-2012 年)的 8,533 次标签重新捕获事件中调查了澳大利亚维多利亚州南岩龙虾 Jasus edwardsii 的运动模式。总共有 83% 的龙虾在其标记地点 1 公里范围内被重新捕获,93% 在 5 公里范围内被重新捕获。虽然主要是居民,但在特定区域内观察到了升高的运动,总体运动方向是从近海到近海区域。运动不受龙虾性别、大小或繁殖阶段的影响。维多利亚州南部岩龙虾的渔业目前分为两个区域,每个区域的商业捕捞总量是不同的。鉴于高水平的网站保真度,
