Thousands of dead fish were found floating in the water along the Kwun Tong promenade over the weekend
(11-7-12/7/2015), releasing a strong stench that many passersby found unbearable.
The dead fish covered a two-kilometer stretch along the promenade, and it took the Marine Department seven hours to clean up about 2,000 kilos, Apple Daily reported.
Several species were identified, including tilapia, seabream, grey mullet and spotted silver scat.
Cheung Ma-shan, science manager at the Eco-Education and Resources Center, said the mass death could be due to the low oxygen content in the water caused by typhoon Linfa.
Chong Dee-hwa from the Ichthyological Society of Hong Kong said the typhoon could have stirred up mud and toxins from the bottom of the sea, thus affecting fish populations.
The Department of Environmental Protection was undertaking tests of water samples obtained in the vicinity.
