The origin and much of Wakame seaweed’s history is discovered in Asia, particularly in Japan. Native to cold temperate seaside areas of Japan, Korea, and China, in recent decades wakame has actually ended up being established in temperate areas all over the world, consisting of New Zealand, the United States, Belgium, France, Great Britain, Spain, Italy, Argentina, Australia and Mexico.
How is Wakame Farmed?
Wakame growing was first studied at Dalian, northeast China, by Japanese scholar Youshiro Ohtsuki who patented cultivation methods in 1943. Since the mid-1960s wakame seaweed has been thoroughly farmed there at an industrial level, but it can also be gathered from the wild. In the Republic of Korea, growing of wakame began in 1964, and was mainly established, promoted and industrialised throughout the 1970s, at that phase accounting for 30% of seaweed farming production in 2013.
In China, comprehensive production began in the mid-1980s, mainly in two northern provinces which have since become the main wakame manufacturers worldwide. Consumption of this macroalgae as a seafood is divided in two categories; the processed midribs are consumed inside China, while the sporophylls and blades are primarily exported to Japan and other Asian countries.
In 1983, wakame farming was intentionally presented into the North Atlantic in the seaside areas of Brittany and at first cultivated at three websites. Wakame growing is also being established in Northwest Spain.
Coming closer to home, in 2010, the New Zealand federal government authorized industrial harvest and farming of wakame under certain conditions– basically, that it be harvested from a man-made structure. There is still much work to be done in this space as a few of the New Zealand guidelines are outdated and complicated. The more we learn more about wakame, the easier this ought to become.
Wakame as an ‘Invasive Types’– aka a ‘weed’!
Interestingly, wakame has been considered as a harmful intrusive seaweed in nations besides those where it is thought about to be native. It is believed that wakame was first presented to foreign waters through the ballast water of freight ships from Asia, as the spores (gametophytes) included in the water can endure long-distance journeys.
In New Zealand, wakame was in truth stated an undesirable organism in 2000 under the Biosecurity Act 1993. It was first found in Wellington Harbour in 1987 and it is thought it most likely shown up in our water as hull fouling on shipping or fishing vessels from Asia. Wakame is now discovered throughout our marine environment in New Zealand, from Stewart Island to as far north as Karikari Peninsula. Despite the fact that it is an intrusive seaweed, in 2012 the government allowed for the farming of wakame in Wellington, Marlborough and Banks Peninsula.
Wakame spreads in two ways: naturally, through the countless tiny spores launched by each fertile organism, and through human activities, many typically by means of the hull of shipping vessels or marine farming devices. It is a highly effective and fertile species, which makes it a serious intruder. However, its effects are not well understood and can vary depending upon the area.
Is Wakame a Pal or Opponent?
So as we discover wakame, do we see it as a buddy or enemy? The drawback of wakame is that it is intrusive and can change the structure of environments, specifically in locations where native seaweeds are missing. By forming a dense canopy, it shades the sub-canopy, and can affect the development of slower-growing native seaweed types. For example, in New Zealand the native coralline algae which are important for paua (edible marine snail) settlement were partially displaced by wakame, resulting in decreased paua quantities.
Furthermore, this invasive seaweed can impact not only the biodiversity of flora, but also the animals communities which are based upon these phytogroups. Wakame can grow on reefs which offer sanctuaries for fish, and gradually cause habitat loss of fishes that dwell on the reefs. Research studies performed in the Nuevo Gulf revealed that the elimination of wakame from attacked sites resulted in an increase in the biodiversity at those places.
Research study indicates that the wakame seaweed or sea vegetable has the potential to end up being a problem for marine farms since it increases labour and harvesting costs, due to fish cages, oyster racks, scallop bags and mussel ropes becoming covered. This development can likewise limit water circulation through cages.
On the other hand, Pacific Harvest is proud to provide a clean, morally collected wild wakame, which is densely nutritious and advantageous for health. The responsible harvesting and proper drying of wakame, and subsequent use of it as an incredibly helpful kitchen area pantry staple, indicates we rid our oceans of a ‘insect’, reduce expenses of removal, and add to a circular economy.

Wakame vs. Nori (Plus Other Seaweed)
Before we begin comparing some common seaweeds, let’s address this question: Is seaweed a vegetable?
Technically, seaweed is a kind of algae, but seaweeds are frequently referred to as “sea vegetables” and often treated as vegetables for culinary purposes.
What consumes seaweed? In addition to people, seaweed (in its natural environment) is frequently taken in by sea urchins, sea snails and plant-eating fish, such as the rabbit fish and parrot fish.
There are three primary varieties of seaweed commonly used as food: wakame, nori and kombu seaweed. However, these are certainly not the only edible seaweeds.
Other consumable alternatives, consist of
- kelp (readily available as fresh or dried kelp, as a supplement or in kelp powder kind)
- ogo seaweed (mainly used in dried form for poke dishes)
- dulse seaweed (frequently utilized as fresh, raw dulse or dulse flakes)
While wakame is consumed fresh or dried, nori is mainly readily available in dried type. What is nori? It’s the most common papery seaweed covering for sushi rolls, and unlike wakame, it is never soaked prior to serving.
Nori is best consumed twisted around other products (like sushi) or toasted.
Kombu and wakame have numerous overlapping health benefits and a similar flavor profile, but wakame is slightly sweeter. Both kombu and wakame are commonly used in seaweed salads and soups.
kelp comes from the brown algae class (Phaeophyceae), and kombu is a particular variety of kelp that’s very common in Japanese, Chinese and Korean food. It can be utilized in salads, soups and smoothies, and there’s also kelp sushi.
Similar to “land vegetables,” sea vegetables also have distinct individual health advantages in addition to lots of overlapping advantages. Overall, wakame, nori, kombu and kelp are all definitely different yet share resemblances in their taste profiles, uses and prospective health advantages. 
Where to Purchase Wakame
The majority of Asian markets will have wakame, however other supermarkets might have wakame in the international aisle, or in a section dedicated to sushi, where the sushi rice, soy sauce, and nori are stocked. Another option is to find it online. Wakame is most frequently discovered in little bags in its dried form, however the dry salt-preserved kind will remain in the refrigerated area, more than likely in an Asian market rather than the common grocery store. 
Adverse Effects of Seaweed
The seaweed advantages and negative effects go hand-in-hand. A benefit to one person may be a side effect to another.
The high-fiber material in seaweed can help digestion, however it can likewise cause digestion discomfort. Each gram of fiber adds up, and a number of servings of seaweed daily can quickly push you over the advised day-to-day allowance of fiber. Too much fiber can trigger bloating, gas and constipation.
Individuals with health concerns related to the thyroid ought to be specifically cautious of overconsuming seaweed because of its high iodine material. According to a March 2014 study published in Nature Reviews Endocrinology, excess iodine usage does not have major effects in the average person. However, people with particular threat elements associated with thyroid diseases– such as hypothyroidism and hyperthyroidism– might find that too much iodine can impact their thyroid function and thyroid medications.
One negative effects of consuming seaweed is associated with the environment rather than the real food. Most of the world’s seaweed is grown in China, but Korea and Japan are also major producers of seaweed. There is concern that seaweed grown on Japanese coasts is polluted by radioactivity resulting from the Fukushima nuclear mishap in 2011. A January 2014 research study published in the Journal of Plant Research study found contaminated samples of algae. Nevertheless, scientists do not advise restricting your seaweed intake due to possible radioactive direct exposure.
Another negative effects related to the environment is heavy metal exposure. According to a February 2018 study published in Scientific Reports, red seaweed contains substantially higher levels of copper, nickel and other metals compared to brown seaweed. Though researchers discovered heavy metals like lead and mercury, they report the danger level is low. However, they recommend the routine security of metals in seaweed.
When it concerns seaweed and seafood, checking the source of your products will assist avoid contamination. The health threats are low, but being familiar with where your food originates from is part of being an informed, health-conscious consumer. 
The correct amount of wakame intake may vary from one individual to another. For the very best suggestions, you should speak with a nutritional expert, a dietitian or another health professional.
