The demand for fish, seafood and algae products from aquaculture is growing - as well as the criticism of many conventional aquaculture techniques. However, innovative eco-friendly aquaculture systems can ensure that fish is not only healthy but can also be produced without causing major damage to the environment. New approaches for environmentally friendly cultivation such as the so-called "integrated multi-trophic aquaculture" (IMTA) and Aquaponics are on the rise. Both methods combine the cultivation of different organisms. The excretions of one species serve the other species as a "fertilizer" or as a nutrient. The waste products from fish or shrimp farming are, for example, suitable nutrients for large sea algae or mussels. If this form of sustainable management is operated in breeding facilities in the ocean, it is called "IMTA". On land this integrated cultivated form is called "aquaponics". It combines the cultivation of fish with the cultivation of crops such as lettuce or tomatoes in a closed ecological cycle. The efficiency and possibilities for the use of these "environmentally friendly" aquaculture techniques will be presented and discussed by experts.

The talks will be in German.
