Ci Lake is a nationally significant wetland rich in fish, shrimp and other water creatures, attracting water birds to nest and forage. However, some people place nets to illegally catch the shrimp, crabs and fish that live in this important wetland. In cooperation with the Kinmen branch of the National Park Police Corps, 4th division of the 7th Special Police Corps, Kinmen National Park HQ will carry out investigation of illegal nets in order to reduce overfishing of Ci Lake's aquatic resources.
Kinmen is located on the East Asian bird migration flyway, and migrating water birds need wetlands en-route to nest and forage. For this reason, Ci Lake wetlands has become a favorite resting spot and winter habitat for water birds. Fishponds and interconnecting water channels can be found throughout the area surrounding Ci Lake, and the area between Shuangli Lake and Ci Lake is also a hotspot for otter activity, providing an important habitat for otters to find food. If the ecological environment within the wetlands is damaged by overexploitation, the ecological resources in the lakes will be exhausted. This will threaten the existence of organisms that rely on Ci Lake wetlands as a habitat, causing imbalance in the wetland ecosystem. Also, placing nets infringes on the habitats of birds and other animals, and sometimes causes injury when wild animals get caught up in nets.
Ci Lake wetland is situated in a National Park Special Landscape Area, and paragraph 2, article 13 of the National Park Law forbids "hunting animals and catching fish ". Therefore, the placing of nets and illegal catching of fish is not allowed in the wetland, and any illegal nets in Ci Lake will be removed. For a long time a small number of people have continued to place folding fishing nets and gillnets in Ci Lake to illegally catch shrimp, crabs and fish. Kinmen National Park HQ has stated that conservation of the natural ecology requires everyone's cooperation, and called on members of the public to comply with the law and protect the precious wetland ecology.
