Heat waves and low precipitation are causing increasing stress on fish populations in Saxony’s waters. According to the Saxony Anglers’ Association, salmonids and trout in flowing waters are particularly affected. “For example, there was already a small-scale fish die-off in the Chemnitz River, where a whole series of brown trout perished,” said Martin Schuster, spokesperson for the association, to the German Press Agency in Dresden.
Low water levels and low precipitation are reportedly creating extremely difficult conditions for the fish in some cases. Water temperatures above 20 degrees could already be life-threatening for some fish species in flowing waters. “They really have to seek out the deeper regions now—that is, the deep sections of the river—where there’s still a bit of oxygen available.” But that’s no longer the case everywhere, according to Schuster.
