All aquariums, depending on the biological filling divided into two types – freshwater and marine.
Freshwater aquarium designed to hold fish, other animals and plants that live in fresh water. It is possible to settle the discus, barbs, dwarf gourami, zebrafish, neon, angelfish and many other fish that are found naturally in rivers and lakes.
In the marine aquarium, filled with salt water, will feel perfectly corals, fish such as zebrasoma, groupers, psevdohromisy, Anthias, stone and sand perch, mullet, as well as other inhabitants of the seas and oceans.
According to the external features of the model fresh and saltwater aquariums do not differ from each other: they have the same shape, are used for their production identical materials. The difference lies in the technique used for the sustenance of the inhabitants of the aqua systems and maintenance of aquariums.
To ensure optimum habitat marine inhabitants is difficult. To do this, you must keep under control the chemical composition of the water, use a certain type of soil, marine aquatic systems equipped with powerful filtering and aeration.
In terms of complexity include freshwater aquarium considerably easier. Continue reading
Aquarium “Sea World”
Aquarium “Sea World” was founded on October 2, 1992. when the governor of Jakarta, Mr. Vyogo Atmodarminto, laid the foundation stone to mark the start of construction of houses for underwater inhabitants. Today, “Sea World” is the largest aquarium in Southeast Asia. The building with surrounding buildings and territories covers an area of more than three hectares, only one main building – is about 4.5 thousand sq. M of multiple exposures.
The concept of the aquarium is rooted in the mentality of the maritime power in the world, which consists of more water than land. The thread of the 17,000 Indonesian islands stretches more than 5,000 kilometers and forms the coastline of 81,000 kilometers, fringed by coral reefs, famous for its biological diversity. Aquarium “Sea World” is a window wide open, giving everyone an opportunity to see with their own eyes and learn more about the precious and fragile marine life in Indonesia.
The main objective of the aquarium is very simple – to expand the horizons of visitors, entertaining them or providing appropriate educational programs. This is the first offshore development in Indonesia, which uses entertainment and educational concept based on what people can simultaneously watch or participate in underwater adventures, and improve their understanding of living beings and nature that will eventually lead to an understanding of their enduring role for the Environment medium. The mission of the aquarium is in three components: education, recreation and the environment.
The main aquarium sharks, rays and thousands of representatives of 351 species of animals are so close that they could be touched, if not walls 80-meter acrylic tunnel. For the convenience of visitors, the tunnel is equipped with a moving walkway. The area of the aquarium is 38 x 24 m, depth ranges from 4.5 to 6 m, and allows you to accommodate the volume of 5 million liters of seawater. Due to its size is the largest marine aquarium in Southeast Asia. The animals were fed daily with hands divers. View this fascinating spectacle can be at a specially organized show with a guide-lecturer through a large window in the room, which is called the amphitheater. On the second floor is an observation deck, which allows you to admire the main inhabitants of the aquarium top. Closer to communicate with the animals and feed them in the presence of personnel in the special pool. The main aquarium inhabited by dugongs, sea turtles, coral reef ecosystem is reproduced.

The ancestors of modern sharks appeared in the oceans some 350 million years ago. The Earth looked very different then than it is now: continents and oceans have not yet purchased our usual shapes. Ancient sharks swam where nowadays sow wheat and build cities. Therefore, fossils of sharks sometimes discover for tysychi kilometers from the sea. Paleontological scientists studying ancient forms – most often find shark teeth. Fossil shark teeth affect its size. Most krupnye- length of 15 cm. And a weight of 340 g – belonged to the monster in the mouth which could put a man gets up to his full height, and it reached 13 meters in length!
After hundreds of millions of years, descendants of the ancient sharks overcome thorny path of evolution continue to surf the seas and oceans. Sharks, of course, in many ways inferior to more progressive in structure bone fish. Sharks do not have kostey- their skeleton is composed entirely of cartilage (though their ancestors had the skeleton). The gill slits are not covered shark gill covers. And most importantly, sharks, like all cartilaginous fish, no swim bladder. In part, though, the swim bladder shark replace fat deposition in the liver. To stay in the water and sink to the bottom, the shark spends his life in constant motion. Sleep she also prihoditsya- not only coastal and reef sharks can afford to rest on the bottom underwater caves. Gills sharks are not so
soversheeny like a fish bone. and extracting only half of the water of dissolved oxygen (y kostnyh- 80%). The shark must continually move more and to its gills continuously washed with fresh water. Not by chance the shark in captivity become “sleepy” from lack of oxygen. Sharks caught in the network, often suffocate and die long before they pull out. Continue reading
