His investigations into pond fertilization gave the pond economy new impulses. He also decisively developed the methods of carp breeding. His practical work on trout breeding promoted salmonid breeding in ponds. He also researched the interaction between the health status of fish and their parasite infestation. With his works on the purification of wastewater, he sets new accents in environmental protection.
