SI~2 Features
Technical Specifications

The SI-2 dual channel flow-through fish stunner has been built to the same high standards as the industry proven SI~5 salmon stunner.

Corrosion and water resistant: All components are stainless steel, high strength plastics, or aluminium and where electrolysis might be an issue, protective coatings and coverings have been applied to ensure electrical isolation and corrosion resistance.

High velocity stunning: The captive bolt has been designed to more effectively provide a consistent instantaneous, irreversible stun. This has been achieved by providing greater velocity and less momentum causing greater shock to the fish's brain without causing inefficient penetrative damage. The SI~2 is effective with only a single hit.

Reliability: The captive bolt has also been designed so that it cannot slip down and returns to the same position each time thereby delivering all blows with equivalent force.

Size Range : The size and species range has been extended to cover fish in the range 200g to 1.4kg.

Low maintenance and service costs: Constructed for durability. All components are modular and can be replaced in minutes even in the field. Pneumatic controls are located in a purpose built protective casing.

Self-feeding delivery and flow through design: The automated delivery system (patent pending) draws fish to the stunner inlet channels while the SI~2 trigger system allows the fish to actuate the stunner and pass right through.

Output Rates : The system is modular and therefore SI~2 units can be added to suit any rate scenario. A typical setup with two SI~2 units averages rates of 80 fish/minute in a fully automated delivery system.

Mobility

The SI~2 and delivery system has been designed to be trailer mountable for quick and easy transfer among ponds and sites. It is also modular in design so units can be rotated as part of an ongoing maintenance program.
