This is the first report of the diurnal change of photosynthetic efficiency of economically important alga, Kappahycus alvarezii from Vietnam. From the figures in our article, you can clearly see the characteristic change of the effective quantum yield during the day and under strong irradiance.

Pyropia tenera survey in Kumamoto(熊本でアサクサノリの調査)

Field survey of an endangered alga, Pyropia tenera, was conducted at a site in Kumamoto Prefecture.

Pyropia tenera アサクサノリ
This species is known as an edible alga in Japan. However, due to the loss of the habitat, extinction of the natural population has also been seriously concerned.
Characteristic photobiology of this species was recently reported by our team.

Porphyra survey at Minami-Satsuma City(坊津で坊ノリの調査)

Field survey of Pyropia (= Porphyra) was conducted at a rocky shore in Minami-Satsuma City, Kagoshima Prefecture. Fortunately, we found a big Pyropia population on the rocks in the upper intertidal zone facing the East China Sea. Indeed, rocks were mostly covered by the alga. 

This alga, known as Bo-Nori for local people, was formerly harvested by fishermen in Winter, and was indispensable to their dietary culture.

Sargassum fusiforme in Kagoshima(鹿児島のヒジキ)

Introducing an underwater view of Sargassum fusiforme population in Sakurajima, Kagoshima, Japan. This is the actual current status before the harvest. This species, known as Hijiki In Japanese, will be harvested by fishermen in April and May.
