Needlefish, its mouth is like a long thin needle, and then its tail swings behind like a willow leaf. He swims fast in the water. Suddenly slipped out of the picture. The relevant staff of the West Lake Water Management Office said that this is needlefish, which is quite common in the West Lake and is not an exotic species. Needlefish, also known as swordfish, is 20 cm long. This kind of fish is not a pure freshwater fish, but belongs to euryhaline. There are both populations living in fresh water and populations living in salt water. Because China has a vast land area, there will be more fresh water population and less salt water population.
Needlefish mainly live in the upper layers of rivers and lakes. This kind of fish often looks for food in groups on the surface of the water, mainly eating zooplankton, but sometimes eating insects. Every summer, needlefish swim to the offshore to breed. Needlefish are mainly distributed in tropical and warm temperate waters of Indian Ocean, Pacific Ocean and Atlantic Ocean. Needlefish are widely distributed in the middle and lower reaches of the Yangtze River and its affiliated lakes. Although this kind of fish is not very big, it is a common small food fish.

Because this fish can not only enhance immunity, but also enhance memory, Guangdong will often eat this fish. Needlefish can also prevent cardiovascular diseases, reduce cholesterol and blood lipids, and is beneficial to vascular health.
