The term refers to both flowering plants submerged in the ocean, like eelgrass, as well as larger marine algae. Generally, it is one of several groups of multicellular algae; red, green and brown.

Seaweed aquaculture shows potential to act as a CO 2 sink through the uptake of carbon during photosynthesis, transformation of inorganic carbon into biomass, and ultimately the fixation of carbon which can later be exported and buried. [5] [31] [50] Duarte et al. (2017) outline a potential strategy for a seaweed farming blue carbon initiative ...
Mariculture, sometimes called marine farming or marine aquaculture, [1] is a branch of aquaculture involving the cultivation of marine organisms for food and other animal products, in seawater. Subsets of it include ( offshore mariculture ), fish farms built on littoral waters ( inshore mariculture ), or in artificial tanks , ponds or raceways ...
Marine Permaculture is a form of mariculture that reflects the principles of permaculture by recreating seaweed forest habitat and other ecosystems in nearshore and offshore ocean environments. Doing so enables a sustainable long-term harvest of seaweeds and seafood , while regenerating life in the ocean.
Extensive aquaculture has been practiced in Korea for several hundred years, with seaweed farming beginning in the 1600s, but modern intensive aquaculture (mainly for seaweed and shellfish) did not emerge until the 1960s. [5] [6] However, total annual aquaculture production was less than 100,000 tonnes in this period. Aquaculture production ...

[38] [39] To induce sporulation, plants are dried for up to twelve hours and placed in a seeding container filled with seawater of about 9-10 °C; salinity of 30% and a pH of 7.8-7.9. [11] [37] [40] Photoperiod is controlled during sporulation and growth phases.
