Impact

For a long time, Norwegian salmon producers were rightly frowned upon for their excessive use of antibiotics. Since then, however, vaccines have been developed for most diseases which, together with preventive measures in animal welfare, have contributed to a dramatic reduction in the amount of antibiotics required to a level that is insignificant today.

Fish lice have always been the arch enemy of farmed salmon. This is why a whole range of measures have been developed over the years to combat them. From natural predators to laser weapons and mechanical cleaning of the fish, everything is included. In future, submersible cages are to provide a final remedy by separating salmon and fish lice.

Farmed salmon in particular has been converted from pure carnivores to flexitarians in recent decades by optimizing the composition of feed. This not only protects natural fish stocks, but also consumers' wallets.

Many people are concerned about the accumulation of plastic in the food chain of fish, but studies show that even when we consume mussels, which are eaten with their innards and stomach contents, we only ingest absolutely negligible amounts of plastic. Other sources of danger are more deserving of our attention.

A well-known FAO graphic shows that sustainably fished fish stocks are continuing to decline. However, the amount of sustainably fished fish is actually increasing worldwide, as healthy fish stocks are being fished much more intensively.

In principle, it can be said that monitored fish stocks develop positively in the long term. Many countries are already well advanced in this respect, while others still have some catching up to do.
