Název v původním jazyce
The use of artificial spawning substrates in order to understand the factors influencing the spawning site selection, depth of egg strands deposition and hatching time of perch (Perca fluviatilis L.)
Popis výsledku v původním jazyce
The distribution of egg strands of perch and factors affecting this distribution was studied in Chabařovice Lake, Czech Republic, using areas with an artificial spawning substrate (A.S.S.) and control areas outside the A.S.S. Perch significantly preferred a calm shore instead of a windward shore for spawning. The depths at which perch egg strands were found increased significantly during the spawning period in both A.S.S. areas and in areas outside the A.S.S. The mean depth of egg strands on individualdates corresponded to the position of 10-12oC water layers. From the third week onward, however, egg strands were deposited in much deeper and colder water. Factors influencing the depth distribution of egg strands were identified as waves, temperature and duration of the daylight period. Factors influencing the selection of spawning sites were identified as wind inducing current, internal seiches and temperature instability of the water column.
