Electrostunning machine by electroshock
The electrostunning machine has been designed to help the raising and manipulation on board a ship of large pelagic species like the Big Eye Tuna and the Mako Shark while carrying out longline surface fishing techniques specifications
of the machine
How is it achieved

Electrostunning is achieved by generating an electric shock while the hook is still in the fish.

The electrostunning machines is made up of 3 main parts:

  • A powerful welding machine
  • An electrode
  • An earth plate

Before raising the fish on board, the electrode is guided through the branch line complete with the earth plate.

This completes the electric circuit which is operated by the individual at his convenience. One simple discharge is enough to stun the animal.

The raising of a
large fish is
easy and safe

The first advantage is operational. The raising and manipulation on board of these large species is both complicated and dangerous for the crew.

This system simplifies the operation and the fish can be raised on board easily prior to the final killing of the animal.

  • Raising made easy
  • Manipulation assisted
  • Killing simplified

Less amount of lactic

acid in the meat

The second advantage is economic.

In the case of the Big Eye Tuna the fish is made to stand still and thus this method avoids the stress associated with the traditional means of raising fish on board the vessel.

The meat then has a minimum accumulation of lactic acid and is consequently more valuable in the Japanese market. It can then be classified as "sashimi grade".

  • Reduces stress
  • Less residual lactic acid
  • Adds value to the animal
Compliance with E.U. directives

The electrostunning process used for the large pelagic species is in total accordance with the E.U. directives associated with the slaughter of domestic animals.
