Description	The distribution of egg strands of perch was studied in relation to water depth and spawning substrate in year 2007 in Chabařovice Lake, Czech Republic, using SCUBA divers. The egg strands were significantly deeper in early May compared to late April. Perch used seven different spawning substrates of which the most important were Potamogeton crispus, Artemisia sp. and Phragmites communis. However, while living submerged vegetation, although more abundant, was generally avoided, dead submerged vegetation was strongly preferred. It appears that dead vegetation is an ideal spawning substrate for perch since placement of the egg strands over those hard, complex three-dimensional structures ensures that the eggs remain well oxygenated 24 hours a day. Factors with significant influence on the distribution of egg strands were as follows (in order of decreasing influence): depth of deposition, type of spawning substrate, date of spawning, and temperature at the depth of deposition.
