[Effect of household sewage on the fertility and size of Ceriodaphnia affinis Lill. in series of generations].
Seven generations of Ceriodaphnia affinis were kept in water of a household sewer. No animal death was observed in the experiment. In a series of generations, the fertility as well as dimensions of newborn water fleas decreased starting from the third generation. These indices in the subsequent generations changed in parallel with the control line.
