Abstract: In order to improve the efficiency of fish passing through ship lock, a ship lock model, referring to No.1 ship lock of Gezhouba Hydraulic Complex, was built to study the fish inducing and expelling effect by various light color and flashing modes. In the test, Grass carp, silver carp and bighead carp were selected as the test objects. The results showed that among the red, yellow, white, blue and green inducing lights, red light has the best inducing effect; among the three flashing modes, namely single flashing, double flashings and variable flashing, double flashings has the best expelling effect. Through arranging the red double-flashing lamps in shiplock chamber, the efficiency of fish passing through the ship lock can be raised by 10%, and the highest is up to 16.7%.
