A large number of dolphins have returned to Hong Kong waters, as the result of the coronavirus pandemic. Scientists say the number of these dolphins off the coast of Hong Kong has increased by 30% due to a break in ferry traffic in recent months.
Dr. Lindsay Porter, a senior scientist at the University of St Andrews, told the Guardian that she was conducting regular research after the Hong Kong and Macau borders were closed. Since that moment she has noticed a large number of dolphins. “I have been studying these dolphins since 1993 and have never seen anything like such a radical change before, and the only thing that has changed is the suspension of shipping,” she said. The scientist says that with the pandemic that has drastically restricted water movement, the number of dolphins in the area has increased by 30% since March 2020.
