Many of the coastal embayments in the Laurentian Great Lakes are listed as areas of concern (AOC) and have expensive remedial action plans in place that aim to restore beneficial uses, such as sustainable fisheries. Our research will determine how key fish species respond to habitat restoration projects, to help ensure the effectiveness of these remediation efforts. While basic habit requirements of key fish species are broadly known, it is not known how fish communities respond to specific restoration. In addition, winter habitat selection remains poorly studied and is usually neglected in restoration efforts. Another difficultly in successfully designing warm water habitat is that the temperature regime is strongly controlled by exchange flows between the bays and lakes that potentially render warm water habitats unsuitable during critical periods.

劳伦特五大湖的许多沿海海湾被列为关注区，并制定了昂贵的补救行动计划，旨在恢复有益的用途，如可持续渔业。我们的研究将确定关键鱼类物种如何应对栖息地恢复项目，以帮助确保这些补救措施的有效性。虽然主要鱼种的基本习性要求已广为人知，但鱼类群落如何对具体的恢复作出反应尚不清楚。此外，冬季栖息地的选择仍然很少研究，通常被忽视的恢复工作。成功设计温水栖息地的另一个困难是，温度状况受到海湾和湖泊之间的交换流的强烈控制，这可能使温水栖息地在关键时期不适合。
