为解决捕鱼量过多,难以将鱼网拖上渔轮,丹麦一家公司发明了一种抽鱼机。这种抽鱼机的吸筒固定在鱼网的口子上,一开动机器,鱼网内的鱼就沿着吸筒的导管被抽到渔轮甲板上。水力系统使吸筒内保持一定的水分,以免使鱼在抽送过程中受损害。在抽鱼时渔轮慢慢地向前开,这样,固定吸筒的渔网边沿就不会下沉。抽鱼速度可以调节。 In order to solve the problem of excessive fishing, it is difficult to drag fishing nets onto fishing vessels. A Danish company invented a fish-feeder. The sucker of this fish feeder is fixed to the mouth of the net, and when the machine is started, the fish in the net is drawn along the sucking tube to the deck of the fishing reel. The hydraulic system keeps the sump in a certain level of moisture to prevent the fish from being damaged during pumping. When fishing fish slowly forward to open, so that the fixed suction tube nets edge will not sink. Fish speed can be adjusted.
