Fishway entrance fish luring method considering fish visual motion reaction
The invention discloses a fishway entrance fish luring method considering fish visual motion reaction. The method comprises the steps that when fishes reach an L-shaped white screen on the downstreamof a fishway inlet, visual organs of the fishes are induced to gradually generate visual motion reaction through fishway water flows and moving vertical stripes on the L-shaped white screen, the fishes swim towards a stripe motion direction and finally enter a fishway; if the fishes miss the fishway entrance, when the fishes swim to the position near the L-shaped white screen arranged on the upstream of the fishway inlet, due to the fact that the movement direction of the vertical stripes moving along with the white screen is the same as the water flow direction, the visual movement reaction generated by the fishes makes the fishes lose the reaction of blocking water flow, the fishes rush to the position near the fishway inlet or a downstream water area of the fishway inlet along with water flow and finally enters the fishway.
本发明公开了一种考虑鱼类视觉运动反应的鱼道进口诱鱼方法，包括鱼类到达鱼道进口下游L型白色屏幕时，通过鱼道水流和L型白色屏幕上的运动的垂直条纹，诱导鱼类的视觉器官逐渐产生视觉运动反应，并朝条纹运动的方向游动，最终进入鱼道；若鱼类错过鱼道进口，游到鱼道进口上游布置的L型白色屏幕附近时，由于随白色屏幕运动的垂直条纹运动方向与水流方向相同，鱼类产生的视觉运动反应会将鱼类失去抵挡水流游动的反应，随水流冲到鱼道进口附近或鱼道进口下游水域，并最终进入鱼道。
