According to Salmar, many fish died, resulting in the central strainer being pushed and fish entering what is known as the “drain pump”.
The incident took place on November 13 at Salmar Setfisk in Stonglandzeit, Senja.
Salmare told the Norwegian Food Safety Authority that the incident affected between 30 and 40,000 fish.
They also believe that some fishermen have escaped from the place.
NRK has so far failed to get a comment from Salmar.
It’s a website Ground based AQ He was the first to mention the incident.
High pressure in the return pipe
In a report to the Norwegian Food Safety Authority, Salmar says there was an error in the biofilter wash, which led to excessive pressure in the return pipe from the vessel.
– The fish entered the center drain and was pumped by a pump used to drain the vessels. Thus the fish are transported to the pump and fish trap. The average weight of fish in the department was approx. 7 grams, says a message from Salmar to the Norwegian Food Safety Authority.
Supervision may apply
The Norwegian Food Safety Authority tells NRK that an incident at a hatchery is serious when fish die or are injured.
They have requested more information from Salmar on how they handled the defection, particularly on measures to prevent a similar incident from happening again.
– If we suspect that any of our regulations have been breached, it would be appropriate to follow up with monitoring there, says Darkjell Andersen, Department Manager for Trams and Svalbard.

He says they did a routine inspection of the business on November 6.
– No acute conditions were detected during this study. A report is being prepared, says Anderson.
According to the Norwegian Food Safety Authority, such incidents are not common, but there have been cases of fish dying in fish hatcheries.
– On a general basis, the production of hatchery fish with recycling technology (RAS) is complex and places great demands on equipment and expertise. If you have an incident first, there are often consequences for large amounts of fish, says Anderson.
Actions have been taken
According to LandbasedAQ, Salmar has notified the Norwegian Food Safety Authority that it has taken steps to prevent similar incidents from happening again.
Among other things, they must go through all the central sieves, check connection points and programming.
– In their message to the Norwegian Food Safety Authority, we will also have an internal review when we have an overview of the scope.
Salmar informed the Directorate of Fisheries that some fish might have escaped.
