科学领域:

  • 生态生态学 生态生态学
  • 侵袭性物种管理 侵袭性物种管理
  • 水生生态学 水生生态学

背景情况:

  • 侵入性鱼对劳伦西亚大湖生态系统构成重大威胁.
  • 了解入侵物种的移动对于有效的控制策略至关重要.
  • 伊利诺伊州和德斯普莱恩斯河是入侵鱼的关键管理区.

研究的目的:

  • 在伊利诺伊州和德斯普莱恩斯河流中调查银色和大头的运动模式.
  • 描述河流池之间的上游和下游移动速度.
  • 评估现有的遥测基础设施对鱼监测的有效性.

主要方法:

  • 贝叶斯的多状态建模.
  • 声学远程测量 声学远程测量
  • 对银鱼 (Hypophthalmichthys molitrix) 和大头鱼 (H. nobilis) 的移动数据进行分析.

主要成果:

  • 大多数入侵性鱼每月都留在他们的河池里 (76.2%的银,75.5%的大头).
  • 下游运动不太常见 (14.2%的白银,13.9%的大头).
  • 上游运动的可能性最低 (6.7%的银,7.9%的大头),下游游泳池的可能性最高,但检测很差.

结论:

  • 侵入性鱼的移动在很大程度上受到池限制,但从招募区上游分散是可能的.
  • 目前的遥测基础设施在关键下游地区检测鱼移动方面存在局限性.
  • 提供了改善监测工具放置和使用的建议,以更好地了解鱼的行为.
