The greatest asset of the aquarium is that it closely mimics natural conditions. The aquarium tanks are continuously filled with fresh North Sea water, through an elaborate pump and filter system.  In this way any build-up of metabolic waste materials that may cause pollution in the tanks can be avoided, and the water quality therefore remains close to that of the surrounding North Sea. This is also true for temperature and salinity, which follow the normal cycles seen in the North Sea.

Many scientists from all around the world, and also those involved in International research projects are able to profit from the aquarium as a natural experimental setup.  They are also able to gain from the many years of experience in the keeping and breeding of the organisms that has been acquired over a very long period of time.  Another service that the aquarium provides is a specimen supply service, where scientists are able to order animals and plants to be shipped directly to them.  In addition to the internal researchers in the institute, many other research institutes, universities and aquariums are also supplied with North Sea Organisms.

Groups of students, schoolchildren and visitors can learn many fascinating facts about the biology of North Sea organisms and their ecology. The most surprising fact for most visitors is the sheer diversity (number of different species) and beauty of North Sea life. Through its aquaria and displays the aquarium is an important link between science and public, raising awareness about the need to protect our marine environments as an area of natural beauty and source of human nutrition.
