PRACTICE! 15 billion mosquitoes disappeared

a few years ago swarmed more than 15 billion midges around over Hald Sø in Viborg.

Now the mosquitoes are largely gone - and this is curiously the concern of bådfolk and fishermen at the Lake Hald.

According to Viborg-folkeblad.dk is the lack of myggesværme namely the expression of the ecological balance in the lake is not functioning optimally.

Usually swarms are of midges at the Lake Hald so intense, that the air is stained black.

- up to 15 billion myggelaver, who lives at the bottom of the lake, before they can become flying creatures, is even very important to the aquatic environment, since they eat the algae that sink to the bottom. These are not eaten, they put themselves on the lake's bottom, and it is not good for anything, " says Jens Christensen from Hald Sea w. klitgaards bådelaug to the local newspaper.

A diver has been down on the bottom of the lake. His video footage shows that there are virtually no mosquito larvae left.

- in Several places there was formed a so-called shroud, " Jens Christensen to the newspaper.

the Shroud is composed of white sulfur bacteria, which indicates an oxygen deficiency.

Jens Christensen believes that the iltningsanlæg, since the mid-1980s have given the Lake Hald artificial respiration, is not functioning optimally, and that the plant, incidentally, has not been cared for properly.

- Since the local plant has not been maintained properly by Viborg Municipality. It is clear that you can't let it continue to run without checking the hoses, which is located on the bottom of the lake. You throw the also not a bike in the lake and expect that you can sit up in the 10 years after, and cycle on, as if nothing had happened, " says Jens Christensen of Viborg-folkeblad.dk.
