Fish in Research
The great diversity in the number of fish species available has made these animals attractive to many researchers. Fish are used to understand normal development and physiology. They are the subject of genetic manipulation and serve as models for cancer research, aging, skeletal diseases, psychological disorders, and more. They are also used in drug screens.
Today zebra fish in particular, are increasingly being used for a variety of investigations and product testing. They are popular research subjects with students who use them in science fair experiments. They are frequently used to study vertebrate development and physiology. This organism is small, reproduces quickly, and it has transparent eggs and embryos. Scientists are increasingly creating mutant zebra fish to identify genes that are essential for normal development. Zebra fish are even being used as models for cancer.
