Euphausia Superba
the Antarctic Krill

Antarctic krill (Euphausia Superba) is one of the most abundant species on earth, with an estimated biomass of around 500 million tons. They are shrimp-like in appearance, with an average body length of only 5 cm, with big black eyes and a reddish semi-transparent shell. They live in all oceans around the world, but can be found in huge swarms in the icy cold waters of the Southern Ocean, where they are harvested from the wild.

 

THE MAGIC OF KRILL

Krill is a sustainable source of protein, omega-3 phospholipids, feed attractants and astaxanthin. 

phospholipid-triglyceride-01.pngOmega-3 fatty acids can be bound together either as triglycerides or phospholipids. In krill, most of the omega-3s are in phospholipid form, whereas in fish oil they mostly are in triglyceride form. The phospholipid form is easily taken up by the organs, giving fish more omega-3s in their cell membranes, resulting in improved health and fillet quality. When omega-3s are in triglyceride form they first must be converted to the phospholipid form, before they can be taken up by cell membranes.

QRILL AQUA

QRILL Aqua is prepared from an extract of ground whole Antarctic krill that is cooked and dried, resulting in a brownish-orange powder containing around 60 percent protein with a nutritionally well-balanced amino acid profile. It is a sustainable source of protein, omega-3 phospholipids, feed attractants and astaxanthin. The benefits of including this ingredient in aquafeeds are many.

Omega-3 triglycerides can be used by the body as an energy source or are stored as fat. For that reason a smaller omega-3 amount will go to membranes. The phospholipid form is easily taken up by the organs, giving fish more omega-3s in their cell membranes, resulting in improved health and fillet quality.
