This is how integrated aquaculture works
Aquaculture, the cultivation of aquatic animals and plants, plays an increasingly important role in feeding the world. It is the food sector that is growing fastest. However, conventional aquaculture is often associated with major ecological problems, such as pollution of the environment through its effluents, the spread of diseases or the destruction of entire habitats.
Many of these problems can be solved with the environmentally friendly approach of integrated multi-trophic aquaculture (IMTA). It combines different cultured animals and plants to form a natural cycle that makes the best use of feed residues and waste products.
The model shown here was developed at the Leibniz Centre for Tropical Marine Research (ZMT) in Bremen. It illustrates an IMTA in a tropical coastal landscape. Especially in developing countries, this form of aquaculture can provide a livelihood.

The feed waste and excreta from the fish are used as food by the other animals and plants. This reduces the nutrient input into the surrounding ecosystems. (Graphic: Juan Pablo Carlos)
