Often the equipment has to be adapted and optimized before it works exactly as intended. Current variables can be: setting of machine parameters, uneven biomass flow, overloading of the system, variation in the fish's behaviour, physiological state and stress level, as well as maintenance of equipment and checking that the machine parameters are correctly set over time. In the case of the Baader 101 machines, it has been found that a certain proportion of the fish are not sufficiently stunned and/or that the point of impact of the blubber knife is incorrectly positioned. In a recently concluded study which focused on the hit point for automatic blueing of salmon (Baader 101), it was concluded that the main part of the fish was anesthetized and blued in a good way.
In order to improve the Baader 101 machines, it is of crucial importance to understand why a certain proportion of fish are not satisfactorily anesthetized. Based on previous observations, mentioned above, in this project we will systematically study:
• Conditions before stunning : biomass flow, possible overload of the ""swim-in"" system, as well as the fish's behavior and stress level.
• The Baader 101 machine : feeding fish to the machine (behaviour, stress and position), as well as design of the inlet channel and possible principles (in sketch form) for holding fish inside the machine which ensures the right point of impact for stunning and bluing.
Main objective:
To ensure good percussive stunning of salmonids.
Sub-goals:
• To establish systematic knowledge of factors that can explain why some fish are not sufficiently anesthetized (failures).
• To improve the feed and mechanism that keeps the fish in a given position in the beating/blowing machine.
• To carry out dialogue/reporting to the equipment manufacturer which enables the optimization of the machine in question.
