SHELTERING BEHAVIOUR OF SPINYCHEEK CRAYFISH (ORCONECTES LIMOSUS) IN THE PRESENCE OF AN ARTIFICIAL MAGNETIC FIELD

The Adult potential of artificial hideouts, outfitted with magnets or their imitations (control), to attract spinycheek crayfish Orconectes limosus was studied.The experiments were carried out within 1999-2002 in an 80-hectar natural lake.There were three parallel setups, with three experimental treatments (hideouts) each.The presently acquired res
