Abstract
    Technological problems can be considered as one of the bottlenecks of research concerned with culturing aquatic invertebrates in the laboratory, as well as at the pilot and mass production stages.Oxygenation problems, circulation of the food and sedimentation problems can easily be solved by adapting the shape of the culturing vessels, i.e., by using funnel-shaped bottoms or high, narrow cylinders. In both cases, the food particles, settled on a very small bottom area, can easily be blown back into suspension using an air pump, which re-aerates the medium at the same time.A number of culturing devices for different categories of organisms, including algae are described and commented on. The only power source involved is compressed air which aerates, keeps the water circulating, resuspends particles which have settled to the bottom and even provides CO2 in the case of algal culturing.
