Diagnostic Description
provided by FAO species catalogs
Thallus consisting of root-like holdfast, short stipe and blade. Blade long-belt shaped, up to one meter long, 10-20 cm broad, with margin undulate and overlapping, thick at the middle and thin at the margin. A short and small stipe and holdfast at the base of the blade. Holdfast sturdy (presenting haptera) with which the algae is fixed to rocky substratum. Colour: thick dark green; blade surface brown, occasionally glaucescent.

Brief Summary
provided by FAO species catalogs
Seaweds of Laminaria japonica grows in subtidal areas from the upper infralittoral level.Sessile.Primary producer. Laminaria exhibit alternation of generations with heteromorphic (morphologically dissimilar) reproductive phases. The asexual diploid phase, the sporophyte, is of considerable size, while the gametophyte, the haploid dioecious phase, is microscopic. Sporophytes produce large numbers of haploid zoospores from sporangia (the called sori) situated on the blade. Zoospores develop into microscopic dioecious haploid gametophytes, male plants producing spermatozoid and female plants developing oogonia. Sori are produced all year round with maxima in July - August and November - December. Also, fragments of gametophytes may develop into new separate gametophytes. In winter, at the beginning of the vegetative period, a new thallus grows from the stipe while the old blade gradually dies. The gametophytes need low temperatures (and blue light) as optimal conditions to become fertile.
Benefits
provided by FAO species catalogs
In 1976 about 176,000 wet tonnes of Laminaria spp. were collected in Japan from wild sources and about 22,000 t were cultivated. Introduced from Japan, the intensive seaweed cultivation in China occurr since 1951. Harvest production: 62 tonnes (1952), reaching three million tonnes dry weight in 1998. Grazers (gastropod snails, amphipods), and diseases (some fungi) can cause great harms to cultivated kelp (the quantity of cultivated algae can lower up to 85%) (Ivin, 1995). Used frequently in Japanese cooking. It is used for making sweets and flavours to foods. Used as a medical drug in Southern China, and as a source of iodine in Russia. Usually sold in dried pieces and found in health food stores and Japanese groceries. L. japonica is collected from wild sources and also cultivated (Japan, Chinese coast). Cultivated in blasted areas of rocky shores or by seeding ropes.
Saccharina japonica
provided by wikipedia EN
Saccharina japonica is a marine species of the Phaeophyceae (brown algae) class, a type of kelp or seaweed, which is extensively cultivated on ropes between the seas of China, Japan and Korea.[1] It has the common name sweet kelp.[2] It is widely eaten in East Asia.[3] A commercially important species, S. japonica is also called ma-konbu (真昆布) in Japanese, dasima (다시마) in Korean and hǎidài (海带) in Chinese.[3] Large harvests are produced by rope cultivation which is a simple method of growing seaweeds by attaching them to floating ropes in the ocean.[1][4]
The species has been cultivated in China, Japan, Korea, Russia and France.[5] It is one of the two most consumed species of kelp in China and Japan.[1] Saccharina japonica is also used for the production of alginates, with China producing up to ten thousand tons of the product each year.[6]
Consuming excessive S. japonica suppresses thyroid function.[7]
Nomenclature
The species was transferred to Saccharina in 2006.[8] Three synonyms for this species name are Laminaria japonica (J. E. Areschoug 1851), its variety Laminaria japonica var. ochotensis (Miyabe & Okamura 1936) and Laminaria ochotensis (Miyabe 1902).[5]
Cultivation
With the development of cultivation technology, though over 90% of Japanese kombu is cultivated mostly in Hokkaidō, production can also be found as far as south of the Seto Inland Sea.
Culinary use
China
Cold sliced kelp at a restaurant in Beijing, China
In Chinese cuisine, sliced kelp is a common hors d'oeuvre which is often consumed with alcohol.
Korea
In Korean cuisine, dasima is used to make broth, deep-fried into bugak or twigak (coated and uncoated fries), pickled in soy sauce as jangajji, and eaten raw as a sea vegetable for ssam (wraps).
It is also used to make dasima-cha (kelp tea).
Cheonsa-chae (kelp noodles) is made from the alginic acid from dasima.
One of Nongshim's instant noodle, the Korean original versions of Neoguri, contains one (or rarely more) big piece of dasima in every package. Odongtong Myon, Ottogi's copy of Neoguri, also has big piece of dasima in every package - Ottogi uses 2 dasimas since 2020.[9]
