Location and timing of the deposition of egg strands by perch (Perca fluviatilis L.): the roles of lake hydrology, spawning substrate and female size
Popis výsledku v původním jazyce
The reproduction biology of perch was studied in relation to lake hydrology, spawning substrate and female size in Chabařovice Lake, Czech Republic. An extreme displacement of water mass, induced by a long-lasting strong wind, caused the abundance of eggstrands to differ significantly between individual parts of the lake. On average, 91% of perch spawning activity occurred at depths greater than 3 m. The mean concentration of dissolved organic carbon (DOC) indicated that the lake belongs to the category where DOC influencing the penetration of ultraviolet radiation, is not responsible for the deep deposition of egg strands by perch. Most probably, the avoidance of shallow layers (less than 3 m deep) results from strong wind/waves coming from any direction. Larger perch females started to spawn earlier than their smaller conspecifics and they used shallower layers for depositing their egg strands.
