Abstract
Aquaculture is a sunrise sector that fulfills the needs of food security, nutrition, health, poverty alleviation, and economic benefits. However, the Sagacious use of the available resource makes them sustainable for the future era. Marine aquaculture is undeniably a key future direction for the production of food. However, traditional aquaculture involves some significant drawbacks, the major one of which is the surplus discharge of organic matter and dissolved nutrients. To mitigate the environmental impact, integrated multi-trophic aquaculture (IMTA) systems, which advocate the integration of fed fish with inorganic and organic extractive species, may offer a sustainable solution. In IMTA, the integral component seaweed plays a pioneering role by reducing the impact of nitrogen-rich effluents from cultured fish waste in the coastal ecosystem; that is, they play a bio-remediation role. Besides, they have also been involved in bio-mitigating climate change. Seaweeds in general have a variety of applications in human welfare and specifically in regard to the present study, especially in the food and biorefinery fields. Edible seaweeds are exceptionally rich in proteins, lipids and dietary fibres; they contain high quantities of essential minerals and store various forms of important antioxidants including vitamins and protective pigments. The emerging interest in seaweed commercialization and production methods makes IMTA a highly relevant approach both environmentally and economically.
