Fish luring and repelling method
The fish luring and repelling method comprises the following steps: separating oxygen-enriched gas and nitrogen from air by using an air separation system; generating bubble water from the oxygen-enriched gas and water by using a micro-nano bubble generation system; each fishway pond chamber is internally provided with a pond chamber fish induction device, and each pond chamber fish induction device comprises a first bubble water pipe for injecting bubble water into the corresponding fishway pond chamber; a river reach fish inducing device is arranged on the riverbed of the downstream river channel and comprises a second bubble water pipe and a nitrogen pipe, and the second bubble water pipe and the nitrogen pipe extend from the upstream side of the fish inlet of the fishway to the opposite bank of the river. Second bubble water holes are formed in the second bubble water pipe at intervals and inject bubble water into a downstream river channel, and air outlet holes are formed in the nitrogen pipe at intervals and used for spraying out nitrogen separated by the air separation system to form a water curtain barrier. Water dissolved oxygen in a downstream river channel, near a fish inlet of the fishway and in the fishway can be efficiently increased, and oxygen-enriched water is provided for fish upstream.
一种诱驱鱼方法，利用空气分离系统从空气中分离出富氧气体和氮气；利用微纳米气泡发生系统将富氧气体和水生成气泡水；在每个鱼道池室内设置有池室诱导鱼装置，池室诱导鱼装置包括第一气泡水管将所述气泡水注入到鱼道池室内；在下游河道的河床上设置有河段诱导鱼装置，该河段诱导鱼装置包括第二气泡水管和氮气管，所述第二气泡水管和氮气管从鱼道进鱼口上游侧向河对岸延伸布置，在所述第二气泡水管上间隔设置有第二气泡水孔并将所述气泡水注入到下游河道内，所述氮气管上间隔设置有出气孔并用于将空气分离系统分离出来的氮气喷出形成水幕屏障。可高效增加下游河道、鱼道进鱼口附近和鱼道内部水体溶解氧，为鱼类上溯提供富氧水体。
