 Monitoring of fish migration is a measure to:
@@ Line 7: / Line 7: @@
 A fish passage is optimal for monitoring of the fish migration since the fish is restricted to migrate within a small and well-defined volume of water. Typically, monitoring and enumeration of fish should be done at the outlet of the fish passage, giving the true number of fishes that pass a migration barrier. The most common monitoring systems are:
-*Mechanical counting systems, such as gates trigging some sort of switch
+*Mechanical counting systems, such as gates triggering some sort of switch
 *Video cameras
 *Sonar devices
@@ Line 16: / Line 16: @@
 There are also systems combining these techniques, such as mechanical counting with video trigging.
 In addition to counting of fish passing fishways, monitoring of upstream migration may cover larger areas and time periods to explore the behaviour of fish on their upstream migration. This can be carried out with radio or acoustic telemetry techniques, where receiver antennas in strategic places register the position of tagged fish with different accuracy levels. Both PIT and telemetry monitoring requires that fish is captured and tagged before monitoring can start.
