I am glad to present “fishbag – Art and Science out of the River Belly” at:
Subject of AquaLife 2012:
In a recently published book, the journalist S. Solomon argues that water is surpassing oil as the world’s scarcest critical resource. The amount of water use within the last century increased dramatically“ much more than population growth. But only 2 % of water on earth is fresh water. Water scarceness arises from expanding deserts, global changes and urbanisation. The extensive use of fresh water, contamination due to spills or accidents, pollution from agriculture, factories and sewage plants threatens existing water stocks. So, the safeguard and preservation of water quality is a prominent challenge of the present. There is no time left to wait.
Oceans contribute to the production of the main amount of biomass and serve as the most efficient scavengers of carbon dioxide. Extensive use of the oceans by shipping traffic and marine aquaculture threatens this sphere. Climatic shifts cause changes in organism distribution with increased algae blooms. Marine pollution is a recurring threat to aquatic life. To recognise and minimise such impacts in time and space, monitoring networks display continuous water quality parameters. The comprehension of different parameters from moving ferries and fixed measuring stations enables water surveys for long- and short-term evaluation and modelling.
Chemical and biological parameters are determined by the use of established scientific methods to determine the quality of water. AquaLife 2012 will focus on the recognition of different parameters from the registration of nutrients, harmful pesticides and other contaminants to the determination of algae and cyanobacteria. This includes different fields of application from sea
water, dam, reservoirs, and aquaculture to drinking water supplies. The second range of topics comprises the biomonitoring of lakes, rivers and water catchment areas from measuring stations. For toxicity assessment by biomonitoring, different test
organisms have been established, such as luminescent bacteria, fish, mussels or daphnids. AquaLife 2012 presents a platform for results and innovations with current methods of biomonitoring.
