Global climate change, water eutrophication and other reasons.

The algal body is grass green, tubular and membranous, clustered, with obvious main branches and slender branches, up to 1 meter high. The base is attached to the rock with a fixator and grows on mid-tidal tidal flats and gravel. The peak growth period is from December to April of the following year.

Due to global climate change, eutrophication of water bodies and other reasons, green tides of Enteromorpha enteromorpha, a large seaweed in the ocean, frequently occur. Large amounts of Enteromorpha enteromorpha float and accumulate on the shore, blocking waterways. At the same time, Enteromorpha enteromorpha accumulates in large quantities and then rots and reproduces. It consumes a large amount of oxygen and emits a foul odor, destroys the marine ecosystem and seriously threatens the development of coastal fisheries and tourism. If there is a large area of ??enteromorpha in the bathing beach, tourists should try to avoid going into the water. Enteromorpha worms are harmful to the body.

Like red tides, proliferating Enteromorpha can also block sunlight and affect the growth of seabed algae; dead Enteromorpha can also consume oxygen in seawater; and studies have shown that chemicals secreted by Enteromorpha It is also likely to have adverse effects on other marine life.

Outbreaks of Enteromorpha will also seriously affect the landscape and interfere with tourism and water sports.
