You might have heard of krill and even some of the studies showing its qualities for aquaculture, but here are some lesser-known fun facts.
In all oceans
One might not see krill very often, but this tiny shrimp-like creature is actually found in all of the world's five oceans. This means that fish naturally feed on krill. Maybe this is why they love the taste so much? Although krill is present in all oceans, they only swim in big swarms around Antarctica.
2x human biomass
Biomass is defined as the mass of living biological organisms in a given area. The total weight of the krill biomass is around 500 million metric tons, which is twice the size of the human biomass. Krill is therefore among the species with the largest biomass on earth, and krill swarms are even visible from space!

10 000 eggs
With such a tremendous biomass, krill is a sought after meal for whales, penguins, birds and fish. It is therefore great that the female krill can lay up to 10 000 eggs at a time – sometimes several times a season.
Low in the food chain
Krill is defined as a zooplankton. They eat phytoplankton or algae during winter which is at the very bottom of the food chain. All other species in the oceans eat krill or species that feed on krill, meaning that krill is vital for life.
Krill for Soviet army
In the 1960's and up until 1990 the Soviet army was fed on krill. The Soviet Union had several boats in the Antarctic Ocean with a sole military purpose: to feed their army. The Soviets knew that krill has amazing nutritional qualities beneficial to the tough lives of the soldiers. The krill was, as sardines, canned in small metal boxes making them last for a longer time.
