Some red eel, Gudgeons, bream and trout were no longer to save. “We are headed to an emergency situation”, warns the Münsterer Klaus Däschler, Chairman of the fishing Sports Association and first husband of the Hessian Fischer (VHF) Association. The lingering drought, but also homemade error threatened springing from the Odenwald, to make a pretty dead trickle through Groß-Zimmern, Dieburg and Münster of flowing and later into the main Gersprenz.
Earlier, he made from large Zimmerner say fishing friends, was the most famous River in the Eastern District of Darmstadt-Dieburg in some places up to three meters deep. Today you could be lucky if the depth was at least more or less continuously at one meter. Behind the clubhouse of the Münsterer fishing is no longer the case: the water is barely 30 centimeters deep here. Can be there also hardly the talk of “Flow” — the more than 20 degrees warm water moves only slightly, is nearly.
Massive fish kills
The result could be a massive fish kills, the discovery Tuesday was just a precursor for this, afraid of Däschler. The persistent drought, although it was exceptional, he admits. The man but contributing by omission of certain measures and also by interfering in the Gersprenz to its current crisis.
As Däschler considered missing deepening of the river bed. The Gersprenz must be dug out in many places on 80 to 100 centimetres, repeatedly removed sediments. “The actions of the previous restoration are well and good,” he says. “The main thing is but neglected.” Only in those places where the water find an adequate bed, could it also flow and reach a depth that will meet even larger fish. In the Gersprenz also catfish, carp, roaches and even Northern Pike are next to eel, Gudgeons, bream and the local trout increased with land resources at home. “When the river bed can accommodate a meters water depth, there are at least 40, 50 centimeters when severe drought.” Still rich from also older copies, which are critical for the reproduction. It’ll be less, as now these fish in the heated threatened to die too low and low-oxygen Gersprenz water. “If we lose these large animals showered, it takes years until the stock has bounced back,” afraid of Däschler.
River bed too low
Problematic, in addition to the low beds, serviced and maintained sluices, Weirs and grid are also bad. And the extraction of water for agriculture and private gardens. The water “is taken from most of the time there, where for example a half a meter is slightly further, larger holes. Just there but the larger fish accumulate then”, says Däschler. His call: “more time brown spots on the home garden accept instead of to transport by water the Gersprenz crisis and the threat of the fish world still taking.”
