The Persaud Catalogue Journal Of Marine Biology: Seagrass Survey At Odaiba Marine Park

This article is a part of our second newsletter, The Persaud Catalogue Journal of Marine Biology. In this second newsletter, we will publish information concerning the various marine flora & fauna of certain places. This newsletter will publish sporadically, & not on a timed basis like The Persaud Catalog. This second newsletter is in affiliation with The Persaud Catalog, however it is a separate entity.  In today’s article, we will catalog the various species of seagrass found in & around Odaiba Marine Park, Tokyo, Japan. On August 22nd, 2024, we sent 2 field agents to Odaiba Park, to research more about the natural marine flora. In this article, we shall delve into the density of the certain marine plants found along Odaiba Marine Park, the areas in which these species are found, & a detailed description of each species. Please note, this was done with the correct permits or permissions & with previous research, do not attempt to imitate this survey without being aware of the permits or permissions that may be necessary to do so. With that being said, let us delve into the intriguing marine plants of Odaiba Marine Park, Tokyo, Japan. 

 

The Survey

Please note, all of these specimens were taken on August 22nd, 2024 in the late afternoon.

 

Species 1: Sargassum Fusiforme (Hijiki)

Our first species is Sargassum Fusiforme, commonly known in Japanese as Hijiki. Hijiki is a species of edible seaweed frequently found along the rocky coastlines of Northeast Asia, particularly in Japan & Korea. It is a staple of the Japanese Diet as it is known for being rich in calcium, & iron. It is said to assist with digestion, as it is high in fiber. Although it has been known to have many health benefits, tests have shown that Hijiki harvested in Japan often has a high level of arsenic, causing many health organizations to advise against its consumption. It is not recommended to harvest this species in the wild for consumption without proper knowledge or precautions. Our specimen for this species is approximately 6 inches long, & 1 inch wide. It was found along Central Odaiba Marine Park. 

Hijiki does not grow very frequently near the coastline, & grows further out into the bay. It is a very distinctive kind of seaweed, known for its dark colour, long stipe, & long thin protrusions away from its main stem.
