Definition of the Subject

Fulfilling aquaculture’s growth potential requires responsible technologies and practices. Sustainable aquaculture should be ecologically efficient, environmentally benign, product-diversified, profitable, and societally beneficial. Integrated multi-trophic aquaculture (IMTA) has the potential to achieve these objectives by cultivating fed species (e.g., finfish or shrimps fed sustainable commercial diets) with extractive species, which utilize the inorganic (e.g., seaweeds or other aquatic vegetation) and organic (e.g., suspension- and deposit-feeders) excess nutrients from fed aquaculture for their growth. Thus, extractive aquaculture produces valuable biomass , while simultaneously rendering biomitigative services for the surrounding ecosystem and humans. Through IMTA, some of the uneaten feed and wastes, nutrients, and by-products, considered “lost” from the fed component, are recaptured and converted into harvestable and healthy seafood of...
