Red tide is a happening that affects the water by colouring it red and result in a death of the marine microorganisms because of increasing the CO2 in the. So, in this newspaper we will discuss the condition of red tide and exactly how much it influences the marines and human being life. Also, we can look at some possible ways in how we can decrease the effects. Then, we will concentrate on the red tide phenomena when it seems in UAE coasts, and the way the UAE administration reacts on it.
Introduction:
There are numerous organisms that happen to be surviving in the marine ecosystem and there are many problems that can affect the microorganisms in the ocean or sea. Among these problem is red tide which brought on by microscopic sea algae. Algal blooms may occur in freshwater as well as marine conditions. In general we can say that red tide arise across the world, and it impacting marine ecosystems in many places like Scandinavia, Japan, the Caribbean, Florida and South Pacific. Also, it is not recent problem or concern because the first time when scientist first noted a red tide in 1947 along Gulf of Florida. However, similar event come in Florida because the mid 1800s. Because of this, red tide bring about very big amount of loses about the world by eradicating the marine organisms, causes diseases to individual, and reduction in economics. So, we will give attention to understanding the red tide problem and its own effects and then implies some possible answers to reduce its impact. Thus, what's the impact of the red tide and what are the ways to reduce it?
Definition of Red Tide:
Microscopic sea algae:
Figure sea shaded red by red tide phenomena
Planktonic microorganisms are the key cause which makes the sea drinking water colored red; they are simply organisms on the surface of the sea (as the figure1 shows). Algae is one kind of planktonic organisms which is good way to obtain food for other marine organisms. You will find harmful and non toxic types of microscopic sea algae. Red tide is shows up when one type of harmful algae or even more than one type are increase in its number all of the sudden. This sort of microscopic marine algae is named Karenia brevis (K. brevis) and it can transform the colour of this inflatable water to reddish-brown color and create a toxins called breventoxin. This (K. brevis) algae can develop quickly and then cover large section of seas surface. So, the colour of the ocean will change to red colorization then it called red tide. But some time (K. brevis) creating bloom that produce ocean appear red or brown and in other time the colour could be inexperienced, blue, crimson yellow or orange and this can even remain to be at its common color. So, these different color of red tide is be based upon the sort of harmful algal bloom but the most frequent color is red so, it called red tide. The damaging algal blooms (HABs), that are algal bloom incidents involving toxic or otherwise harmful phytoplankton such as dinoflagellates of the genus Alexandrium and Karenia.
In addition, the harmful algae which circumstance red tide can be split into three main categories that have about 300 types of micro sea algae. The first group can produce toxins vital and signifies 25% of the type of algae and it have an effect on on fish and peoples health. The next group can reduce the amount of the air from this inflatable water that has red tide. The 3rd group combines both previous categories.
Algal bloom creation :
Nutrient sources can play an important role in affecting algal bloom creation, because algae have a tendency to grow very quickly under high nutritional supply. So, when these materials like specifically phosphorus, extra carbon and nitrogen result from agricultural soils to water that contains algae help to a sudden rise in the number of algae and other plankton. But each alga is short-lived, and the result is a high concentration of dead organic matter which begins to decay and then algal bloom start Concentrated and transferred on the outside surface of this particular, whether in the oceans and seas or rivers and its own concentrations may reach millions of cells per milliliter. Also, abrupt and quick appearance of damaging algal bloom is resulting from coastal upwelling. And this dangerous algal bloom (HAB) is causes negative effects to other microorganisms since it can produce natural toxins.
Time of appearance:
Red tide can look at any time and on any month of the year but probably that occurs on August-November. So, some scientist said that it most frequent in summer and fall, but they have been reported atlanta divorce attorneys month of the entire year in various places.
Red tide can be carried from one spot to another which can occur when it transferred inshore or along shoreline by tide, breeze and currents. The red tide occurrence experienced by almost all of the beaches in the various maritime areas which normally remain a maximum of three times, but if found ideal support such as stock, misuse and sewage and they also remain active and will become more aggravated.
We consider the trend of red tides as an environmental problem since it can transported by wind and cause many breathing problem for the individuals and there are many other bad affect for it on the marine organisms enjoy it can produce waste which have an impact on the anxious system in seafood.
The impact of Red Tide:
First, the impact of red tide on sea organisms:
Fisherise is something important to human since it provide him with food essential for life so when you start to see the ( red tide ) This extension is a proliferation of algae and plankton in a huge quantity and huge as it can help improve the amount of the fish in the ocean and oceans as well as sea organisms staged give food to these fungi. AS a result, lead to the death and tunnel of large levels of fish all varieties on the beach; thus, there are three main reasons for that:
Natural devastation:
Because of the large numbers of the algae and plankton on the normal water the gills of the seafood cloge with marine plankton as a result, lack the ability of seafood to extract air.
Drain and oxygen consumption:
When the proliferation of algae and plankton are too tired food shortages, which means fish and sea organisms will perish and decay and tunnel on beach and also the number of bacterias increase.
Direct poisoning:
Some algae produce toxic substances vital breakdown of the stressed system in seafood, leading to them to fatality and tunnel.
Second, the impact of red tide on the Humans:
Diseases of the the respiratory system:
This is produce by inhalation human to the drizzle of the sea which is packed with contaminants released by algae and plankton and the symptoms are using discomfort in the nose and throat, Tingling in the tongue and lip area, Also they can be afflicted by asthma and allergies in the breasts.
Injury of the digestive system and food poisoning:
Symptoms is vomiting or nausea, cramps and severe diarrhea which is attained by eating fish which contain their body on dangerous algae m Also can infected with real human food poisoning by eating seafood caught in the time of red tide for the content of toxic substances in their physiques on the other hand the individuals can be poisoned through the sea of toxic algae and plankton which for the countries that rely on sea water desalination and immediately exposed to poison.
Complete paralysis:
That achieved through real human usage of shellfish and poisons that are focused inside do not vanish in the cooking leading to diseases people may expire or put up with other diseases.
Diseases and skin area burns:
Algae and plankton secrete some secretions could cause burns up and fungal skin especially for beach goers.
Ways for lowering the impact of the red tide:
Obviously, That Human activities resulted in the corruption of the sea environment. thus led to many damage to him and other microorganisms. So, it is time to take serious actions to lessen the destruction of red tides through some of the items which help to get over the red tide:
1 " Work on the application of the laws which governing the establishment of visitor resorts.
2- Wastewater treatment and Subtractions signing an agreement between the countries that overlooking on a single coast to coordinate among them.
3- Experience and exchange information so as not to have an impact on the fisheries.
4- Spread consciousness among people and anglers through the multimedia.
5- Ongoing training for employees in the seafood farms, and using the modern methods in nutrition.
6- Establishment the follow-up programs on the brief periods of time.
7- Abuse throws the waste of agricultural and professional in the sea and make an effort to use the the least fertilizer.
8- Spray dirt on the areas that show the plankton or algae that cause red tide.
Red Tide in the UAE:
Figure 2. Red tide brought on the fatality of 1200 tons of fish
Red tide causes several problems over the UAE coasts. Individuals who lived in coastal areas suffered with a sizable amount of seafood deaths and induced a terrible smells. In past due of 2008, red tide trend has been visited the UAE coasts. Furthermore, statistics shows that the red tide triggered the fatalities of 1200 tons of fish in August 2008 (as the shape2 shows).
The researches that have been done by the Ministry of Environment and Water in some drinking water samples taken from different areas implies that there are eight species of algae triggers the phenomenon of red tide. These kinds included some types that are poisonous to fishes. Because of this, it caused the deaths of large levels of fish and crustaceans on the shores of the east coastline. Matching to Dr. Salem Aldahri- the director of environmental federal specialist- said that the result of the chemical research confirms increasing of phosphate salts focus and Nitrate in the; these are the primary Nutrients that Stimulates the growth of algae that triggers the red tide sensation. Thus, the UAE hosted in those days experts from the Regional Company for Safety of Sea Environment to go over this phenomenon to lessen the effects and also to stop the depth increasing it to neighboring countries. However, the physical researches results that the marine environment of the UAE was ideal to the growth of algae that causes the red tide. Also, the temp was suitable, as well as the high attentiveness of dissolved air in surface normal water and low air concentration in the depths. Furthermore, the Ministry of Environment and Water has taken since the start of the phenomenon several measures in order to lessen its negative impacts in UAE coasts. In 2003, the major red tide problem was saved in the UAE in Mussafah Channel; where a large amount of fish deaths. As a remedy of this problem they opened the channel to be able to get better flow of water. Furthermore, there are several records published in magazines said the happening has plagued neighboring emirates Ras al-Khaimah and Fujairah for months, killing a huge selection of tones of fish. Additionally, Dubai beaches which is a great travelers destination. Thus, red tide induced significant problem in the economy Dubai. So, the UAE government offers instructions to fishermen never to fish during the red tide length of time. Furthermore, they made workshops and lectures to anglers and the general public people about the impact of the red tide and recommend them to avoid swimming and diving in the ocean especially children; because the ratio of the CO2 is high. Also, sitting down in the beach will cause itchy rash in the skin.
