Artificial multiplication technique of large silverfish in Hongshan Reservoir
Hongshan Reservoir is located in the lower reaches of Laoha River in the northeast of Chifeng City. it is a large plain reservoir integrating flood control, irrigation and aquaculture, with a rain area of 24500 square kilometers and a total storage capacity of 2.56 billion cubic meters. the fish culture area of the reservoir is 80, 000 mu ~ 130000 mu in low water season and high water season. The fertilized eggs of large silverfish were introduced into the reservoir in 1995, and the fishing yield reached 2.5kg/ mu in 1998, and the yield decreased in the following two years, but in recent years, due to the adoption of more perfect proliferation management measures, the resources have been gradually restored.
