A bird stands on a cliff when red tide appears on January 10 in Zhuhai City, Guangdong Province, China.The first red tide appeared in Guangdong Province in 1998, until now, an average of 10 times a year.

Red tide phenomenon is a form of algae blooms, proliferates and accumulates excessively in a sea area.Depending on the species of algae, seawater may be red, green, yellow or brown.

Red tide carries toxins, obstructs respiration and kills many marine animals such as shrimp, fish, oysters ., causing much damage to the aquaculture industry in Guangdong province.

According to the Guangdong provincial government, seawater pollution is the main cause of red tide outbreaks.

The whole province has 28 river mouths pouring into the sea, many factories, industrial parks, and untreated agricultural waste water are dumped directly into the sea causing pollution.

In addition, the increasing number of marine aquaculture farms also leads to changes in marine ecological environment, increasing the risk of red tide outbreaks, Mr. Ta, professor of Fisheries and University Hai Guangdong said.

To improve the marine ecological environment, Mr. Ta said: "Coastal areas should reduce the number of aquaculture farms, increase the number of farms cultivating seaweed, kelp" and at the same time "raising the awareness. marine environmental protection ".
