We use MSC*-certified fish whenever possible. However, we have decided against labelling it at the serving counters in order to save the cost of the necessary license fees. In addition, MSC has attracted criticism: there are cases where overfished stocks are still MSC-certified. In order to preserve the remaining stocks and not support questionable fishing and rearing methods, we do not use tuna and shrimps in the canteen and will not use Hoki apart from May 2019.
Highly endangered and therefore not on the menu: tuna
*MSC= abbreviation for Marine Stewardship Council / MSC is a non-profit organization that has developed standards for sustainable fishing.
