The most versatile electrofisher in the world.
Point or transect sampling made easy.
Smith-Root designed and constructed this barrier for the U.S. Fish and Wildlife Service to prevent migration of lamprey into upstream spawning habitat.
The small weir is provided with a lip, making lamprey passage difficult. The electric barrier provides additional deterrence.
Four steel rail electrodes are located in slots in the Insulcrete™ deck and side walls. Three pulsators provide the repelling electrical field. The electronics are housed in a small adjacent building.
