Hangali Reservoir, located in Keerqin right-wing Middle Banner in the northeast of Inner Mongolia Autonomous region, is a medium-sized side reservoir on the Huolin River. In January 1996, 780000 fertilized eggs of Ctenopharyngodon idellus were transplanted from Luhun Reservoir in Henan Province and hatched naturally under the ice. Through the growth inspection in that year, it was found that the transplanted large silverfish grew and developed well, reached sexual maturity in late December, and began to reproduce naturally, achieving the first-class introduction effect. In January 1997, in order to consolidate the population of the large silverfish, it also reported to

What should be paid attention to when releasing fish fry in winter in the reservoir
Every winter is the golden season for releasing silver carp, bighead carp, grass carp and herring to the reservoir. However, many mariculturists report that a large number of dead fish and swimming diseased fish will be found on the water surface of the reservoir within 2 ~ 7 days. The skin of these fish loses luster and the body surface mucus increases. According to the above symptoms, it can be inferred that the fish is suffering from a typical "incompatibility of soil and water". The disease is mainly caused by the sharp change of water temperature and the strong stimulation of nerve endings in the skin of fish, which leads to the dysfunction of internal organs and its death.
