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.
