Not everyone can swim with fish in the ocean. But they can enjoy underwater life in another way—by visiting an aquarium (水族馆).
Experts do not really know when people began keeping fish as pets. But they say that people have been interested in fish for thousands of years. The ancient Sumerians (苏美尔人) were the first civilization to keep fish in ponds more than four thousand years ago. The Chinese kept and studied carp and goldfish more than one thousand years ago. The ancient Romans kept eels as pets. And the Greek philosopher Aristotle made what is believed to be the first known study of sea life, including sharks and dolphins.
By the middle of the 19th century, science had shown that plants, fish and other sea creatures could survive together under water. Therefore, it was no longer necessary to change the water in a tank for fish to live there. This led to the building of the first public aquariums.
The first aquarium opened in London in 1853. In the next fifteen years, other aquariums opened in Europe and the United States. By 1928, there were about forty-five public aquariums in the world. Today everyone still seems to be enthusiastic for undersea creatures and it is reported that millions of people visit aquariums in more than thirty countries every year.
