PROCESS AND DEVICE FOR BREEDING SMALL AND VERY SMALL AQUATIC CREATURES

摘要

In a device and a breeding method small aquatic organisms and microscopic, using a container (17) filled with water in which is inserted a culture vessel (24). The culture vessel is closed at its bottom by a filter (4) or a filter device suitable mesh width. Therefore, the culture space (1) lying within the culture vessel (24) and the external water space ( '' space '' uncultured 23) between the culture vessel (24) and the water container (17) are in fluid contact. To achieve the best culture results with a minimum of care, an inlet duct (11) and an outlet pipe (10) for water, at least, open space '' uncultured ' (23) of the water container. the inlet duct (11) is arranged so that, through it, of the filtered water can be pumped directly below the filter (4) of the culture chamber (1). The invention enables the cultivation of small and microscopic aquatic organisms for extended periods, for example, the lifetime of a generation in optimal conditions, without the need for troublesome procedures and time-like change of 'water.
