Resumo: One-dimensional design of fish passes often leads to an unsatisfying solution. The problems are due to insufficient, if not completely missing, collaboration between biologists and civil engineers. In the present paper, a new type of fish pass is presented. A labyrinth flux develops in a system of sequential sluices and baffles in between, which uncouple the supercritical flow of the single sluices. A series of biological, hydraulic and numerical experiments was carried out in order to investigate the optimum configuration in terms of geometric issues, regarding the biological needs and performances of organisms to be transported. Following this optimization, fish can control the prevailing flow conditions quite well. Because the air entrainment into the water is avoided, fish perception is not affected. A geometric extension regarding the needs of small fish, bottom fish, and macrozoobenthos decreases the selectivity and predation pressure on them.
