The Dugong

Dugong is a marine mammal of the Sirenian order and has a life exectancy is estimated at around 30 years. The dugong is a quiet animal with the defenses, except its impressive size. Certain individuals can reach 4 meters long with a weight up to 900 kg. The Egyptian dugong is usually up to 2.5-3 meters and up to 500 kg. It generally lives alone or in small groups and frquents open water coastal habitats. They may also live in wide shallow mangrove channels and in the lee of large inshore islands. Dugongs are also regularly observed in deeper water further offshore in areas where the continental shelf is wide, shallow and protected. Dugong is the only marine mammal to feed on zoster's (marine plants) living on sandly shallow bottoms. Sirenian are sometimes called "sea cows".
To breathe, the dugong has to surface. Its apneas owed long minutes. When it inhales, it emits a relativly noisy kind of "phaaa" sound. Dugong makes chrip and bark-like sounds, in mother-calf communication and during mating. They reach sexual maturity at about 10 years old, age to which appear at the male two defenses which are in fact two modified incisors. The period of gestation lasts 12 or 13 months and the female gives birth to itscalf that will be independent after approximately 2 years. During period, the mother teaches its calf the principles of migration as well as location of places to feed. The female can reproduce every four or five years. We can consider that a female will have no more than 4 or 5 youngs during her life. The dugong thus has an extremely low reproductive rate.
The conservation of dugongs is necessary because it is part of the ecosystem and contributes to the fertility of the sea. Its dung is an important food source for some animals, which increases the mass of fish available for human. Its disappearence would destroy forever the balance of the marine ecosystem and affect the future of the human.
The dugong already disappeared from Maldives' Islands, Mauritius (Rodriguez), and Taiwanand from certain parts of the Persian Gulf. The dugong has an area of distribution today that goes from the Red Sea to the islands of the Southwest Pasific ocean. The International Union for the Conservation of Nature has classified the dugong species as threatened by extinction. Although commercialized hunting of the Dugong has had a dramatic effect on the sea grasses which make up the dugongs entire diet.
In Egypt, two mounting the front: HEPCA and TENDUA. They have set up a data collection system allowing the identifications of the animals and the areas they mostly frequent. Normally, there is about fifteens dugongs in Egypt. In parallel, they are working to stimulate individual awareness and for the adoption of a comprehensive, protective behavior leading to the creation or expansion of marine protected areas. As for the economic point of view, HEPCA has estimated that the revenues generated by the presence of the dugong in Marsa Abu Dabab were of 18000$ in 2007. The extintion of the dugong along the Egyptian coastline will enrich no one. Will this number be sufficient to obtain protection for the dugongs, via the creation or expansion of marine protected areas around their habitats?
The future of dugongs in the Red Sea depends on us, our choice and our will to return some regeneration space to Nature, where species such as the dugong may live in peace.
