Seaweeds or macroalgae are multicellular photosynthetic organisms that can float freely or be attached to objects like rocks in the
subtidal or intertidal part of the marine environment [1].Seaweed can also enhance the worldwide vegetable diet consumption and food supply
chain.These include eradicating hunger (SDG2), promoting health and well-being (SDG3),
ensuring access to affordable and clean energy (SDG7), addressing climate change (SDG13), and preserving life in the oceans (SDG14),
all of which have resounding advantages that support other SDGs [8].It now accounts for 51.3% (34.7 MMT, wet
weight) of all marine aquaculture worldwide, with China and eight other Asian nations dominating output (99.6%) [4,5] (see
Figs.2 year? 1) [3].
