Evaluation of key stimuli at bypass entrances
Abstract
Actual European and International guidelines are raising the demand for an attraction flow between 1% and 10% of competing flow at the fish pass entrance. The statistical analyzes of the reaction of fish following the stimulus of attracting current showed no significant change or increase of number of individuals entering the fish passes. Finding the entrance was independent from the availability and strength of a guiding current. In this ongoing research project key stimuli such as phonotaxis, thermotaxis and phototaxis at bypass entrances will be evaluated.
