Extended information:

In Taiji Town Bay, Japanese fishermen slaughtered dolphins, and the surrounding sea water was dyed red. From September to March every year, thousands of dolphins gather in the waters near Taiji Town because there are abundant fish resources here. Dolphins will also play with their companions when they are feasting. From time to time, a large number of dolphins will jump out of the water, forming a beautiful local landscape.

However, local fishermen regard these dolphins as a great wealth. Once they find traces of dolphins, they will drive boats to hunt them. Some of the slaughtered dolphins are even a few days old, and some of them will be kept in aquariums, and waiting for them will be disease and death. Every year, about 23, dolphins are slaughtered in Dolphin Bay.
