Aquatic experimental animal

There are many types of aquatic animals, and only more than 30,000 fish are named, occupying an important position in the ecosystem. For a long time, people's understanding of aquatic animals is mostly limited to aquatic food and ornamental animals.

In fact, as early as two thousand years ago, "Erya" and "Said the Words" had records of fish embryo development. In the 1950s, Myron Gordon began to cultivate pure fish experimental animals; in the early 1960s, Professor and Professor Zhu Xi were used to study with goldfish, Wenchang Fish, and African Places in the early 1960s. Severe cytology, embryonic development and nuclear migration.

The endless aquatic experimental animal resources are becoming the focus of many researchers. The types of aquatic experimental animals used in China are shown in the figure.

There are many types of aquatic animals, many biology characteristics, and most of them are in the low stage of evolution. The organizational structure is relatively simple. It is a commonly used experimental animal commonly used in toxicology, developmental biology, physiology, ecology, and genetics. Because of its sensitivity to environmental pollution, it has become an important experimental animal for environmental protection scientific research.

In the past two or three decades, fish in the aquatic experimental animals have developed rapidly in the animalization of experiments, and the standardized products have gradually established, and some of the research trend of replacing terrestrial mammals are unstoppable. Among them, the zebra fish that has completed genomic sequences has entered the era of genetic function research. With the advancement of technology, aquatic experimental animals will be widely used by more researchers.
