- Spread of bad odder as a result of decomposing organic matter of algae and fish.
- fish and other marine organisms kills.
- Desalination plants stopped.
- Coastal tourism affected largely.
- Impacts on fishing activities.
- Large quantities of fish dead in fish cage farm.
- This phenomena may be chronic , and expected to be repeated again depending on environmental conditions suitable for growing algal spores.
Among the risks that involve the Red tide phenomenon is the deterioration of the quality of sea water affected area . As a result the intake of the seawater to the desalination plants is severely affected. Accordingly, work was stopped at intervals in several desalination stations in the Eastern Region, they are:
- Kalba Water Desalination Station
- Fujairah Port Desalination Station
- Khorfakkan Water Desalination Station
- Ghalyla Water Desalination Station – Ras Alkhaimah
What are species of algae behind the occurrence of red tide in the UAE marine coastal water?
The results of identification have shown the existence of 12 species of phytoplankton that cause the red tide during 2008-2009, where 8 species common one as follows:
The fifth species is dominant one in the UAE coastal and marine water during 2008-2009.
Life cycle of phytoplankton species
The life cycle of dinoflagellates involves asexual reproduction by means of binary fission, or Sexual reproduction by fusion of two individuals to form a zygote , and that remain mobile in most dinoflagellate and is called a planozygote, this may form a resting stage (cyst) –hypnozygote. These cysts can remain for several years and they reproduce and divide into thousands of cells in the appropriate environmental conditions of temperature, light, oxygen and sufficient nutrient.
Geographical distribution of Cochlodinium polykrikoides wordwide
Studies and reports indicate that the algae Cochlodinium ploykrikoides is distributed in East Asian States, India, the Mediterranean sea, Spain, USA and Mexico, where the phytoplankton move across water currents from a space to another space as shown in the following map between Japan and Korea.
