Abstract
    Aquaculture is comparable to agriculture , and both are necessary for the nutrition of mankind. Aquaculture research made possible a considerable increase in yields of several fish species in central Europe. By intensive carp farming in ponds with pellet feeding and aeration more than 10.000 kg/ha are attainable. Production of fingerling carp using the cooling water of power stations reduces time for rearing marketable carp and diminishes mortality of fish. Yields in ponds may be increased by polyculture with phytophagous cyprinids. Trout culture at high intensity level is possible in open recirculating systems. Also selection and well balanced diets can essentially improve results of fish culture. Moreover, important problems for the future are protection of fish as human foodstuffs with regard to contamination, production of fish flesh of high physiological value for human nutrition, using new species for aquaculture and providing methods for fish culture without environmental damage. Therefore, research will be an indispensable instrument for successful development of aquaculture in the future.
