Overview
Integrated multi-trophic aquaculture (IMTA) is an aquaculture approach that combines species from different trophic, or feeding, levels within the same system so that the byproducts of one species become inputs for another. Typically, fed species such as fish are cultivated alongside extractive species, including shellfish that filter suspended particles and seaweeds or other organisms that absorb dissolved nutrients. By recycling nutrients and wastes through these complementary species, IMTA aims to reduce the environmental impact of aquaculture, improve resource efficiency, and diversify production, making it a model of more sustainable and balanced aquatic farming. The concept draws on ecological principles, mimicking the way natural ecosystems link organisms through flows of energy and nutrients, and it is studied as a strategy for limiting the accumulation of waste while generating multiple harvestable products. Within the broad field of aquaculture research and development, IMTA is examined alongside work on the biological components, such as algae, shellfish, and microorganisms, that can contribute to nutrient cycling and ecosystem function in cultivated systems. This page gathers peer-reviewed, open-access research within the broad field of aquaculture relevant to integrated multi-trophic aquaculture and sustainable production.
