Not only that, but residents of Venice have also seen fishes returning in their canals since they have gone through the lockdown.

Images and videos have been shared on the internet, and they show fish swimming in the clear waters of the canals.

The waters of the canals are connected directly with the Adriatic Sea.

Not only that, but a number of dolphins have also been seen swimming by a dock in Cagliari, Sardinia.

The clearing of the canals come as activities in Venice have been placed on hold due to the coronavirus lockdown.

In Italy, people are being advised by the government to stay inside.

In a video that was shared by Marco Capovilla, a Venetian real estate agent, you can see tiny fish swimming in the clear waters of the canals.

Before the outbreak, the canals were filled with dirt and debris.

The resident said that he had seen clean waters in the canal as it was so full of tourists.

He said, “During these days, traffic in Venice has become almost absent.”

Marco added, “The city doesn’t have sewers, so normally everything goes into the canals, including detergents and cosmetics. Thanks to the quarantine, we are experiencing a cleaner environment.”
