Assessment of habitat enhancement measures for the protection of fish populations
Description
Measures to protect fish populations in waters influenced by hydroelectric power plants have so far focused almost exclusively on longitudinal connectivity for fish. In particular, short-distance migrators are likely to benefit significantly from habitat enhancement measures within the water body and its floodplain compared from merely achieving connectivity. To better understand the significance of individual measures and their interconnections for the fish populations of the river Inn, a research concept was developed during preliminary studies conducted from 2013 to 2015. The main project is planned for ten years and is divided into three parts, where measures in the tributaries and standing waters of the Inn floodplain (Part I), bank widenings and hydraulic structures in the main channel of the Inn (Part II), and the interconnection of different habitat segments (Part III) are studied. Preliminary results clearly indicate that the near-natural bypass waters represent an important habitat for fish and benthic invertebrates and serve as a source of biodiversity for the main channel.
