kalaülekäigud
Kalaülekäigud, also known as fish passages or fishways, are structures designed to help fish migrate past obstacles in rivers and streams, such as dams, weirs, or culverts. These passages are crucial for maintaining the ecological health of aquatic ecosystems by allowing fish to access spawning grounds, feeding areas, and escape predators. Without them, migratory fish populations can become isolated, leading to reduced genetic diversity and potentially severe population declines.
The design of a kalaülekäik varies depending on the type of obstacle, the species of fish it
Effective kalaülekäigud are designed to mimic natural conditions as closely as possible, with appropriate water flow,
