利用灯光诱导捕鱼,这种方法已延用了好几百年。移动的灯光也可诱导鱼类通过水站的水道,但鲑鳟鱼类一般不会被灯光所吸引,却会对闪烁的灯光作出反应,即受惊逃避反应。挪威的二位科学家研究了如何诱导鲑鱼摄食的方法。养在网箱里的鲑鱼抢食饲料的时间很短暂,因为饵料会很快沉入箱底。如果网箱很大,鲑鱼远离投饵区时,有时还未发现投下的饵料,饵料就已沉入箱底。要使鱼有更多的机会获得饵料,在投饵前用声音、灯光或其它手段来“通知”他们则是一
Using light to induce fishing, this method has been used for hundreds of years. Moving lights can also induce fish to pass through the waterway’s waterways, but salmon trout are generally not attracted to the light, but respond to flashing lights, ie, to avoid the reaction. Two scientists from Norway studied how to induce salmon feeding. The time it takes for salmon caught in cages to grab feed is too short because the bait quickly sinks into the bottom of the tank. If the cage is large, the bait may have sometimes not been found when the salmon is far from the feed zone and the bait has sunk into the bottom of the tank. To give the fish more chances to gain access to the feed, they are “informed” by sound, light or other means prior to the feed
