Integrated multi-trophic aquaculture (IMTA) is a sustainable farming practice that combines different species from various trophic levels in a single system. In this approach, waste produced by one species serves as nutrients for another, creating a balanced ecosystem. For example, fish can be raised alongside shellfish and seaweeds, where the shellfish filter the water and the seaweeds absorb excess nutrients. This method enhances productivity and reduces environmental impacts by minimizing waste and improving water quality. IMTA promotes biodiversity and can lead to more resilient aquaculture systems, making it an attractive option for sustainable food production in marine environments.
