Optimar Electric Stunner - The new standard for humane slaughtering

november 14, 2023

Optimar Electric Stunner ensures humane slaughtering of all fish and crustaceans trough the slaughtering process. Our commitment to humane handling is tied to our dedication of producing a final product of high quality.


Making a commitment to fish welfare 

With the rising awareness of fish sentience and the growth of aquaculture, there is an increasing need for ethically produced fish products. The demand extends beyond sustainability to include considerations for good animal welfare. Achieving humane slaughter is crucial in meeting elevated animal welfare standards in farming.

Optimar Electric Stunner is the most humane way to automatically paralyze fish and crustaceans in a controlled process. In compliance with European and Norwegian standards, the Electric Stunner renders the animal unconscious safely and in a stress-free manner. Our electric stunner has been in use for more than 15 years, on Salmon, Trout, Cod, Sea Bass/Bream, Catfish, Crab, Lobster and Shrimps. 

How does it work? 

Optimar electrical stunning system can be used as part of a commercially viable slaughter system. The system allows for a more humane slaughter than the traditional method of chilling in ice slurry without pre-stunning and also has product quality benefits. The system can also be operated with less staff and is easier to use in bad weather conditions.

Here is an example of how our electric stunner is used during harvesting of farmed salmon. The Optimar Electric Stunner is set up in a complete stun and bleed line to both sedate and slaughter the salmon, before bleeding out during transportation to the processing factory. 



Electric stunner for different species 

The Optimar Electric Stunner is well known and approved for a number of different species to maintain animal welfare during the slaughtering process, such as:

 - Wild fish: Cod, Haddock, Saithe, Whiting, Catfish, Halibut, Mackerel, 
 - Farmed: Salmon and Trout
 - Crustaceans: Crab, Lobster, Shrimps and Nephrops.
