Spawning brushes in the Wienfluss

On behalf of the Stadt Wien – MA45 Wiener Gewässer we installed so-called “spawning brushes” in the Wienfluss, for fish that need aquatic plants for spawning such as rudd, roach or carp! Fish migrating from Donaukanal to the Wienfluss hardly find any aquatic vegetation to spawn from the river mouth to Stadtpark, therefore we provide remedy with the spawning brushes. We are fully confident that the fish will accept them and are looking forward to the first spawning observations 🙂

With high demands on quality and accuracy of the analytical results, we have established a quality management system for our chemical testing laboratory according to the guidelines of ÖVE/ÖNORM EN ISO/IEC 17025. In September 2010, the laboratory was accredited as a testing laboratory by the Federal Ministry of Economics, Family and Youth (BMWFJ).
(GZ: BMWFJ-92.714/0659-I/12/2010 Identification No. [PSID] 315) Our analyses are carried out in accordance with national and international standards. All procedures are laid down in our quality management manual, which our customers are welcome to consult. The correctness of our work is confirmed several times a year by international interlaboratory comparisons.
