Although whooper swans do not eat scaleless carp, the fish is a vital link in the food chain as many other birds feed on it. Abundant carp can help small aquatic animals flourish and help restore the lake's biodiversity, said protection chief Wu Yonglin.
According to the Qinghai province department of agriculture and animal husbandry, more than 35,000 tons of scaleless carp live in the lake, 13.5 times the amount in 2002.
The province dealt with 34 violations of the fishing ban, confiscated 4,422 kg of illegal harvests, and destroyed 4,500 pieces of fishing equipment this year, Xinhua News Agency reported on Nov 28.
