摘要：
Patterns in the quantitative manifestation of meristic characters of seismosensory canals on the head of roach have been studied in fish from populations inhabiting ten river and pond water areas of the Udmurt Republic exposed to different kinds and levels of anthropogenic pollution. Trends of interpopulation variation in the average numbers of pores in some seismosensory canals have been revealed, and their statistical relationship with the level of pollution has been evaluated.
