Crustastun Electro Stunner for Lobster and Crab

The Crustastun Electro Stunner is a purpose-built appliance designed to humanely stun live crustaceans — primarily lobster and crab — prior to cooking. It uses a controlled electrical current to render the animal insensible almost instantly, providing a credible alternative to methods such as live boiling or manual dispatch, which have attracted increasing scrutiny from animal welfare bodies and legislators.

In practice, operation is straightforward. The crustacean is placed belly-down on a sprung tray inside the unit. Closing the lid brings the animal into contact with the electrode sponge and saline solution. The operator activates the stun cycle via a front-mounted button, and the current passes through the animal's brain centres — stunning is achieved in approximately half a second, with the animal ceasing to be sentient within ten seconds. The cycle is consistent and repeatable, which matters in a professional kitchen where service pace and procedural reliability are important.

Beyond the welfare case, operators frequently report a measurable improvement in meat quality. Because minimal stress is experienced by the animal, stress hormones are not released into the flesh. The electrical current also begins the tenderisation process, which can produce a noticeably better texture in the finished dish. For restaurants where shellfish quality is central to the menu, this is a practical as well as an ethical consideration.

• Meets recognised humane stunning standards for crustaceans
• Consistent, repeatable stun cycle — reliable during busy service
• Improved meat texture and flavour through reduced stress response
• Simple single-button operation requiring minimal training
• Stainless steel construction suited to commercial kitchen environments

The unit weighs 22kg and requires a standard 13-amp supply, making it straightforward to position within a prep area without significant infrastructure changes. It is most at home in restaurants, hotel kitchens, and seafood specialists where live shellfish are handled regularly. For very high-volume sites processing large quantities continuously, it is worth discussing throughput requirements with us to ensure this unit is appropriately matched to your operation.
