NANJING - The Taihu Fishery Administration will spend 100 million whitebait germ cells into China's Taihu Lake, the third largest freshwater body that suffered algae outbreak last year, as one of the measures to clean the lake due to algal pollution. The move earlier this week came after the neighboring Anhui Province put 1.6 million fish into the fifth largest body of freshwater, or Chaohu Lake, which also faces a threat from algae.
These germ cells come from Mongolia Autonomous Region, so as to avoid inbreeding, an administration spokesman said. The school of fish is expected to curb the blue algae pollution as they live on plankton, including algae and protozoan. Excess of blue-green algae removes oxygen from the water, killing fish and other aquatic life, which then decay and release toxin. The output of whitebait, a small sprat famous for its fresh and tender meat, in Taihu stood at 400 tons in recent years, compared with the record of 2,000 tons. From June to August last year, the nutrient run-offs caused blue-green algae to bloom in lakes such as Taihu, Chaohu and Dianchi, endangered water supply in nearby cities and posed a great threat to aquatic life.
The algae outbreak in areas of Taihu provided an alert at the end of May as it rendered tap water undrinkable for about 10 days for more than one million residents in Wuxi, Jiangsu Province. The Chinese government has set a timetable for control of the country's pollution-plagued lakes, aiming to restore them to their original state by 2030.
