In the cultivation of various fish species in aquaculture is an important to have enough dissolved oxygen available for fish respiration.This oxygen can be produced by the photosynthesis of aquatic plants and algae. The purpose of this study is to investigate the influence of two macrophytes Myriophyllum spicatum and Lemna minor on uptake of oxygen in the feeding of perch. The experimental part was consisted of three tanks with Perca fluviatilis - as one without macrophytes (like a control) and the other two with macrophytes (Lemna minor, Myriophyllum spicatum). Oxygen uptake rate was measured at water temperature 23±1°C. The measurement of pH, dissolved oxygen and temperature was made with a portable combined meter.The mean oxygen uptake rate is better in the cultivation of Perca fluviatilis with Lemna minor
