In 1997, Denison barbs were presented at the International Exhibition of Aquarists, where they won first place. After this began the mass capture and export of fish from India.

Their population has declined by more than half. Due to the almost industrial fishing barbs were almost on the verge of destruction.

The decline in the number of fish in nature was also influenced by the pollution of rivers with industrial waste.

The government of India has taken steps to protect the barbs. In certain periods of their fishing is prohibited.

In Southeast Asia and Europe, fish are bred on special farms.

But Denison are still listed in the Red Book as a species threatened with extinction.
