Enhancement of fish stock by habitat manipulation in artificial coastal waterways

在海岸人工水道中操纵生境以增加鱼类资源。人类住区显著改变了沿海自然水道的空间特征。人工水道（如运河）作为鱼类栖息地的价值鲜为人知。我们将评估人工运河作为鱼类栖息地的意义，并测试人工鱼礁改造对鱼类分布和丰度的影响。我们将调查人工鱼礁是否能提高运河内的鱼类产量，而不仅仅是作为鱼类聚集装置。这项研究将解决渔业生态学中的一个重要问题，并有助于制定人工水道的管理准则。

Enhancement of fish stock by habitat manipulation in artificial coastal waterways. Human settlement significantly changes the spatial characteristics of natural coastal waterways. The value of artificial waterways, such as canals, as a habitat for fish is poorly known. We will evaluate the significance of artificial canals as a fish habitat, and test the effect of habitat modification by artificial reef installation on fish distribution and abundance. We will investigate whether artificial reefs enhance fish production in canals, rather than simply acting as fish aggregation devices. This research will address an important question in fisheries ecology and help formulate management guidelines for artificial waterways.
