The 10 World’s Most Popular Seaweed- According to Food Agriculture Organization (FAO) in 2018, there are 10 World’s Most Popular Seaweed Species. In the FAO publication of 2020 entitled “The State of World Fisheries and Aquaculture 2020”, this institution describes the species of algae with the biggest production in 2018. Algae commonly have multiple benefits to humans. In our daily life, we call it seaweed. The term seaweed (seaweed) is commonly known in the world of trade. In the science world, algae are low-level plants, because they do not have special roots, stems, leaves, and flowers. In general, algae consist of 4 classes based on their pigment content, namely Rhodophyceae (red algae), Phaeophyceae (brown algae), Chlorophyceae (green algae), Cyanophyceae(blue-green algae).
From time to time, historically, seaweed has been used by the Chinese and Japanese as special food and as medicine. In Japan, there are many species of algae that can be used in daily cooking, and Japanese people like to consume seaweed. The use of seaweed has multiple functions, gelatine, pickles, vegetables, salads, wakame, kombu, and nori. Statistically, some algae have the highest production because of their major function in human lives. Here are the Rank of 10 World’s Most Important Algae Species According to FAO Publication entitled “The State of World Fisheries and Aquaculture 2020”.

Brief Description of 10 World’s Most Popular Seaweed
1.Japanese kelp (Laminaria japonica)
Japanese Kelp or Laminaria japonica become the world’s most popular seaweed in 2018. Based on the FAO report, the production of this species reached 11.4 million tons. Taxonomically, this species Phylum: Ochrophyta; Subphylum: Phaeista; Infraphylum: Limnista; Superclass: Fucistia; Class: Phaeophyceae; Order: Laminariales; Family: Laminariaceae; Genus: Laminaria; Species: Laminaria japonica. So based on the taxonomy, it has close relation with the other algae, namely Laminaria agraphia, Laminaria digitata, Laminaria hyperborean, Laminaria sinclairii.
Seaweed Laminaria japonica usually grows in the subtidal zone. This species contains a total dietary fiber of 50.7%, which is the highest among all plants and seaweeds (Kim et al, 2018). Based on its habitat, laminaria japonica are mostly found on rocky shores at low tide and in the subtidal zone to a depth of 8-30 m in the North Atlantic and North Pacific but some species can live at depths of up to 120 m which are usually found in the Mediterranean and Brazil but require water conditions. which is clear.
In Japan and Korea, this type of algae is widely consumed as Kombu and Haidai in Japan and China, and several Southeast Asian countries. Kombu is widely used as a spice and cooked together with vegetables, meat, or cooked into processed foods. Statistically, this species is widely cultivated in China, Japan, and Korea.
2. Eucheuma seaweeds nei (Eucheuma spp.)
Eucheuma nei seaweed (Eucheuma spp.) become the second world’s most popular seaweed in 2018. Its total production in 2018 reached 9.2 million tons. Biologically, Eucheuma can grow through the apical meristem network consisting of a group of cells that are active in the development stage. Statistically, the Philippines, China, Malaysia, and Indonesia are some of the countries that have a huge production of this commodity. Functionally, Eucheuma species are widely used in the production of carrageenan, materials for cosmetics, and food.
3.Gracilaria seaweeds (Gracilaria spp)
Gracilaria seaweeds or Gracilaria spp. is the 3rd most popular Algae / seaweed in 2018. In that year, the production of this species reached 3.4 million tons. This seaweed can be classified in Division: Rhodophyta; Class: Florideophyceae; Order: Gracilariales; Family: Gracilariaceae. Gracilaria usually grows warm waters throughout the world. This alga cannot tolerate with temperatures below 10 °C (50 °F). Based on its habitat, gracilaria usually live in all oceans except the Arctic Ocean. Functionally, Gracilaria is a nutritional food in some countries, namely Philippines, Japan, and Korea.
4. Wakame (Undaria pinnatifida)
Wakane or Undaria pinnatifida become one of the most important Algae in The World in 2018. Its production in 2018 reached 2.3 million tons. This species has considerable economic importance as a food source in Japan, Korea, and China. Taxonomically, this species can be classified in Phylum: Ochrophyta; Class: Phaeophyceae; Order: Laminariales; Family: Alariaceae; Genus: Undaria; Species: U. pinnatifida. This species usually grows in cold, temperate coasts of the northwest Pacific Ocean and is usually served as Salad and One of the Ingredients of Soup.
5. Nori nei (Porphyra spp.)
Nori nei or Porphyra spp. has the favorable one with the production in 2018 reached 2 million tons. Historically, Porphyra cultivation has a long journey. It started since the 17th century in Japan, Korea, and China. Until now, this alga has become one of the most important shallow-water coastal industries in these countries. Functionally, this species can be used as Nori. Nori is a name in Japanese of foodstuffs in the form of sheets of dried seaweed. The Nuri has function as decoration and flavoring assorted Japanese dishes, side dishes when eating rice, and other functions.
6. Elkhorn Sea moss (Kappaphycus alvarezii)
Kappaphycus alvarezii, the elkhorn sea moss, is a species of red algae. Elkhorn sea moss (Kappaphycus alvarezii) is the next biggest one. In 2018, the production of this species reached 1.5 million tons all over the world.

7. Brown seaweeds (Phaeophyceae)
Brown seaweeds or Phaeophyceae is the 7th world’s biggest production of algae. In 2018, its production reached 0.89 million Tons. Most brown algae live in marine environments and brown seaweeds provide shelter and food for small animals. Functionally, for human needs, it can be used raw materials for alginate.
8. Laver (Porphyra tenera)
Laver or its scientific name Porphyra tenera is the 8th world’s biggest algae. In 2018, its production reached 0.85 million Tons. Taxonomically, this species can be classified in Division: Rhodophyta; Class: Bangiophyceae; Order: Bangiales; Family: Bangiaceae; Genus: Pyropia; Species:P. tenera. Functionally, this species can be used as dried seaweed food.

In Japan, this species is known as Hijiki. Hijiki is a healthy food because it contains important minerals such as calcium, iron, and magnesium.
