Fischnetz: A project on fish catch decline in Switzerland
Long-term reviews are necessary to appreciate the full outcomes and impacts of the scientific, societal and policy
perspectives of transdisciplinary projects. Here, thirteen years after its completion, we assess the significance of a
five-year (1999–2004) Swiss research project. The Fischnetz project aimed to identify the causes of fish catch
decline and propose remedial measures. Engineers and scientists from different...
Anthropogenic pollution of the environment
Pollutants in the Antarctic
For millions of years, the Antarctic Ocean has been considered as an ecosystem isolated from the other oceans by the polar front and therefore very stable and untouched. It is now known that anthropogenic pollutants reach Antarctic waters. In a multi-year project we investigated the pollution of Antarctic fish with persistent organic pollutants and their effects on the fish.
Effects of mycotoxins on carp
Mycotoxins are natural toxicants produced by fungi. These fungi affect grains, especially under warm and humid conditions. Grains will be increasingly used as animal feed in aquaculture, resulting in a major concern regarding the health status of fish. Hence, in a series of studies, specific mycotoxins are being analysed according to physiological parameters and the immune system of carps - one of the most common...
Endocrine-active substances are compounds which influence regular hormone activity. If the resulting effects are negative, these substances are also called Endocrine Disruptors (ED). The hormone systems of humans and fish are quite similar: As a result, substances that are used for therapeutical purposes or for hormonal contraception are also perceivable in the hormonal system of fish which have made their way into (sewage) water. Additionally, there...
