Abstract
The paper describes results of studies on adaptation of the principle of Chinese fish polyculture, dominated by grass carp fed green forage, to Polish conditions. Over the course of the experiment, fish yield increments obtained averaged 1,444; 960; 1,374; and 1,498 kg ha-1 in the four successive years. The data demonstrate that a modified polyculture allows to arrive at relatively high fish yields without the need to use expensive feeds and substantial labour input.
