Fish pass is the passage for fish migration.Described with popular language, some fish, which have from lower reaches of river, to be migrated to river
The habit of upstream spawning is flowed, after river has blocked river because artificial origin has such as built checkdam, fish are upstream whirled
The passage of trip will be destroyed.In order to protect the habit of fish, it is necessary to which passing through dam builds artifical flume as fish migration
Passage, i.e. referred to as fish pass.Current enter fish pass from upstream, flow out fish pass from downstream, but fish are from downstream into fish pass, from upper
Fish pass is swum out of, thus fish pass upstream intake is referred to as fishway exit, and fish pass downstream delivery port is fish pass import.
In order to realize that fish pass crosses the purpose of fish, fish pass usually requires to meet claimed below：First, depth of water requirement, fish pass domestic demand
Keep 1.0~1.5m depth of waters；2nd, slope requirement, in order that fish can be along current upstream migration, flow rate of water flow in fish pass
It is less than the speed of fish migration, this requires fish pass to need to keep a relatively slow and stable gradient；3rd, when upper pond level becomes
