• Description:
  In 2010 electrofishing was conducted at four sites located in the Ner River section flowing across the City of Łódź. Two species co-dominated in abundance: perch (36.1%) and roach (34.2%). The site downstream from the Stefańskiego Ponds was most abundant in fish. Among 13 species represented by almost 3 thousand specimens captured there perch and roach (36.9% and 32.6%, respectively) were dominants, while ruffe (16.5%) was a subdominant. The most human-impacted site was located downstream from the Dobrzynka Stream inflow, where no fish were caught. A comparison of the present state of fish fauna with that of monitoring studies carried out during the recent decade in the river’s section flowing across the City of Łódź indicated no significant changes in fish assemblage structure. The species composition and assemblage structure of the section is positively influenced by the recreational ponds, which feed their adjacent reaches of the river with fish. Unfortunately, in two of the sampling sites the situation of fish remains critical, which is testified to by almost total lack of them. The reason of this situation is low water quality and isolation (chemical barrier) of the upper Ner River system from the Warta River.;
