The classification of Bluefin Tuna includes a few different types, all of which are endangered and it is estimated that they will soon become extinct. The categorization of each type of Bluefin Tuna species is based on geographical location although the exact number varies from 3-8.

This demand has caused new and harmful fishing methods to be created. They have become incredibly popular in sushi as well as other food and for this reason the population has declined; however, there are methods that could be used in order to prevent the species from becoming extinct.
