Аннотация

The article presents data on the mercury content in the muscles of perch Perca fluviatilis (L.) in four large reservoirs of the Vologda region (Kubenskoe and Vozhe lakes, river and lake (Lake Beloe) parts of the Sheksna reservoir) collected during the period 2007–2018. The metal concentration varied widely: from 0,01 mg/kg for perch from Lake Vozhe to 1,51 mg/kg for perch from Lake Kubenskoe. The highest percentage of fish with mercury content exceeding the established SanPiN 2.3.2.1078-01 norms (29,4%) was recorded in perch from Lake Kubenskoe, while the smallest – in fish from Lake Vozhe (5,4%). In fish from the Sheksna reservoir the content of the toxicant in muscles did not go beyond the accepted SanPiN 2.3.2.1078-01 norms. For all perch samples, a statistically significant positive correlation between mercury content and linear-weight characteristics, as well as fish age, was established.
