New method tracks each king crab
Individual marking of king crab has been highlighted as an important measure to gain better control of resources and prevent illegal catch.
Now it has also been documented that the animal welfare can be safeguarded, as long as the brand is set correctly, reports the Fisheries and Aquaculture Industry Research Finance (FHF).
In the research project Merkrabbart, Nofima has investigated how different branding methods affect the welfare of king crab. The study shows that T-Bar marking in the back shield causes low mortality, little damage and no negative effect on meat quality or food safety.
-The use of T-Bar is by far the most effective method for marking king crab. It has been important for the industry to document how the method affects animal welfare, hygiene and food safety, says Frank Jakobsen, specialist and FHF manager for the project in a press release.
Proper labeling
Although inflammatory reactions were recorded around the main point, the project shows that the vitality, bacterial level and physiological values of the crab are not adversely affected.
To ensure good animal welfare, the mark must be placed in the rear of the back shield – a little to the side of the center line – without damaging the fourth walk, which the crab uses to clean the gills.
