The main reason for the increase in dead fish phenomenon this year in Shanghai Suzhou River is unscientific release

Xinhua News Agency, Shanghai, August 15th (Reporter Dong Xue) Walking on the banks of the Suzhou River, occasionally seeing one or two fish rolled over the river and drifted on the river, and the cleaners were salvaged by boat. "This is what we have been salvaged. In many cases, the dead fish appears, and the weight of the day is several tons." Said Zhang Haibo, a staff member responsible for the cleaning of Suzhou River.

The reporter learned from the Shanghai Municipal Rong Environment Sanitation and Water Management Office that since this year, the Suzhou River Management Station has received 13 incidents of the Suzhou River's large -scale dead fish incident, which is far exceeding previous years. Moreover, these fish are not wild, and most of them are released by citizens.

According to Cai Haifeng, deputy deputy branch station of the Suzhou River Management Station, after the 42 -kilometer shoreline of the central urban area of ​​Suzhou River was basically connected at the end of 2020, citizens' release activities have become more and more frequent. Some people are released on large festivals. There are also people who come to release in the middle school entrance examination and college entrance examination.

Generally speaking, there is a tendency to increase the increase in release and the professionalism of release tools. There are two characteristics of the area where dead fish concentrated. One is densely residential areas, and the other is to facilitate release locations such as the pro -water platform.

"Most of the fish released by citizens are purchased from the market. These artificially cultivated fish are not easy to adapt to the water of the Suzhou River." Cai Haifeng said.

Cai Haifeng said that in the past, the Suzhou River became a "black smelly river" for passers -by to cover the nose due to pollution. Today, after long -term governance of the Suzhou River, the water quality that can be carried by its water quality is still very limited. In particular, when it comes to the weather such as high temperature and heavy rain in Shanghai this summer, the water quality will deteriorate in a short period of time, and the oxygen content will be further reduced. It is difficult for citizens to survive.

In addition, unscientific release also causes problems such as fish and fishing. "Someone stood on the flood -control wall to use net pockets to fish fish. This is a safety hazard, and some people sit on the green belt along the river. In addition to destroying the lawn, some domestic garbage will be left." Zhang Haibo said.

The reporter saw some publicity boards that persuade citizens to release scientific release by the Suzhou River. At present, on the one hand, the Shanghai Municipal Rongs and Environmental Sanitation Management Office strengthens the surface inspection and operation supervision on the one hand, and strengthen emergency response to emergency pollution; on the other hand, it will strengthen publicity and persuasion, and call on the public to not release them in the Suzhou River.
