Farmers at Jiading's Wangxin Aquatic Farm are busy these days with exporting fry of four kinds of fish to aquatic farms across the country.
"Orders for 600 million fry have been placed," said Yao Dexing, the farm's general manager. In addition to neighboring Zhejiang and Jiangsu provinces, fry have been sold to farms in Beijing, Tianjin and other areas in northeast China.
A month ago, when a dozen of fish weighing more than 10 kilograms each were resting in the pool, aquatic cultivation expert Shen Wenkui said: "All these fish are of good species selected from the Yangtze River."
According to Shen, when spawn is produced, it is transferred to a hatching barrel. Spawn becomes fry within 24 hours and is moved to bigger pools. Farmers then use aerators to inject oxygen into the pools. This prevents bacteria from growing in the water and also increases the fry survival rate.
Fry swim like tadpoles in the pool, waiting to be sent to farms. Farmers start packing fries around 4am, putting about 100,000 fry into one nylon bag which is injected with full of oxygen. These bags will be put into carton boxes before heading for the airport at around 7am. During peak season in May, nearly 400 boxes of fries are sent to the airport every day.
From laying spawn to transportation, the whole process is supervised by farm staff with relevant files recorded.
All fry have certificates containing details of their origin, guaranteeing that the fish are safe from pond to table.
