From March to November 2000 planctonic Rotifera of the collapse pond Bojszowy - Jedlina were studied. Rich fauna of Rotifera (71 taxons) was recorded. One new for Silesia Region species Erignatha clastopis (Gosse) was found. The qualitative composition of the Rotifera community in that pond differed from other investigated collapse ponds. In spite of high eutrophy domination and constance structure indicated staid character of the Rotifera community in the Bojszowy - Jedlina pond.
