Ace Aquatec's Humane Stunner Mark 3 (HS3) is targeted at flat fish which do not pass readily through round tubes. Launched in May 2008, the pre-production 3 metre machine is the most compact yet made by Ace Aquatec, with a design capacity of 12 Tonnes per hour.

The HS3 is fully self-contained and can be moved to the harvest tank and be made ready to operate within minutes.

In common with all Ace Aquatec machines it is fully automated and simple to operate. Once the machine is in position and connected to the water and electricity supplies the entrance and exit hoods are inserted into their slots.

Once the power is turned on the machine waits for the operator to select OPERATE. It fills itself with water, conditions the conductivity using the in-built salt tray and, when satisfied, it automatically starts the recirculation pump. The machine then tests the water in the stun tray and starts the inclined conveyor when the level in the tray is adequate for stunning. The lights turn to Green and harvesting can commence.

During harvesting the machine adjusts its voltage and adds salt or fresh water to maintain optimal stunning conditions.

REVIEWS:

"The HS3 had all the qualities we look for in a machine. It was easy to use and did not slow us down. All the fish were stunned and we did not see any signs of recovery." (Robert Davies - Selonda UK)


"The HS3 provided a good humane method of stun for the small turbot being harvested. The stun was quick and effective and the volume though-put was excellent. The machine would be most appropriate for larger scale harvesting operations and would significantly improve welfare compared to current methods." (Jamie Smith - Pinneys of Scotland)

"I was very impressed with the HS3 stunner. It addresses an urgent need in the industry for a method that is near instantaneous, very low stress and looks good to the layman. This is a vital part of the farming process, makes a huge difference to the quality and enhances the reputation of the farmers that use them. Seachill actively push the aquaculture industry to develop humane stunning for all species and we make it a condition of supply where a suitable method is available and proven in the field. The HS3 is simple, effective, well constructed, efficient and most importantly is based on good scientific research and development that works." (Nigel Edwards - Seachill)
