Fish Barriers and Deterrence Systems

Electric Guidance and Barriers

Many carp migrate in early spring from lakes to marshes to spawn. We use low-voltage electric barrier/guidance systems to block these migrating carp and direct them into traps for removal. Once in the trap, the carp are removed using conveyer systems. This greatly reduces labor and increases effectiveness. A test in Rice Creek, MN in 2021, showed that 65% of carp spawning run (over 10,000 carp) were removed using these systems.

The electric barrier/guidance systems we use are portable, can be easily modified to fit specific study sites and installed in only a few days without extensive site engineering. The electric field they produce is mild and does not cause fish mortality. It is designed to guide the fish into traps rather than paralyze them.
