Sažetak
By its presence, silver crucian carp or chiton (Carassius auratus gibelio Bloch.) makes lot of damage on fish-farms. By its nutrition way, the chiton competes with carp, thus reducing its growths and increasing the nutritive coefficient what is unjustified both economically and technologically.
The diclinous and hermaphroditic way of procreation influences the spread of this species. After the dissection of an chiton exemplar of 10-12 dag in October 1995 in Našice “Ribnjak 1905” it was stated that it had 23% of male fish. Spawn was in the IV. stage of sex maturity according to Kiseljević.
The ways of chiton coming and going to particular pounds as well as measures to control it are analyzed in the text. It is recommended to turn full attention to the filling and re-filling of pounds, prevent the coming of wild fish and fill canals and pounds thoroughly.
