Seaweed farming or kelp farming is the practice of cultivating and harvesting seaweed. In its simplest form farmers gather from natural beds, while at the other extreme farmers fully control the crop's life cycle .
Seaweed is largely transported from coastal areas to the open and deep ocean, acting as a permanent storage of carbon biomass within marine sediments. [65] Ocean afforestation is a proposal for farming seaweed for carbon removal. [53] [66] After harvesting seaweed is decomposed into biogas (60% methane and 40% carbon dioxide) in an anaerobic ...
Under this harvest regime, beds can recover their harvested biomass within a year, [42] [43] and no long-term impact of the harvest on the biomass or morphology of A. nodosum has been observed. [44] [45] Several studies have looked at the impact of the harvest on associated species and have found only limited short-term impacts. [46] [47] [48]
Growing seaweed offshore with the purpose of sinking the seaweed in the depths of the sea to sequester carbon has been suggested. [41] In addition, seaweed grows very fast and can theoretically be harvested and processed to generate biomethane, via anaerobic digestion to generate electricity, via cogeneration/CHP or as a replacement for natural ...
Researchers warn a massive belt of Sargassum seaweed headed towards the state could be infected with the deadly Vibrio bacteria Flesh-eating bacteria found in seaweed on Florida beaches Skip to ...
Harvesting of Turbinaria is largely done by collecting drifting thalli on the water surface or directly from the substratum. [4] The genus is commonly harvested in India, Indonesia, and the Philippines for alginate production. [17] [18] [19] It is abundant year-round in French Polynesia and India, [20] [19] and is harvested seasonally in ...
