Monitoring Fish Populations
In cooperation with DFO a fish ladder was installed on the main Sackville River in 1990 to allow unimpeded fish migration past the falls at Hefler's Lumber Mill. The ladder or fishway incorporates a cage in which migrating fish are temporarily trapped so that they may be counted. The ladder is checked daily for Atlantic salmon from May to November every year.
Periodically, the SRA uses electrofishing to monitor fish numbers in the Sackville River system. Electrofishing temporarily incapacitates fish so they can be caught, identified and measured before being released.
In low water, fish are not able to get over the falls.
Why leap the falls when you can use the ladder?
Juvenile salmon, trout and many other species are monitored.
