Abstract

The invention discloses a culture method capable of reducing the mortality rate of grass carp. The method includes the step (1) of performing sand filling around a culture pond, wherein the width of asand filling area is 2-3 m and the water depth of the sand filling area is controlled to be 1-1.5 m; the step (2) of placing a water quality improver in the culture pond every 15-20 days; and the step (3) of adding 18-24 g of nutritional agent in every kilogram of fish feed. The culture method capable of reducing the mortality rate of grass carp is low in cost, the growth speed of the grass carpcan be effectively promoted, the survival rate of the grass carp can be effectively ensured, and the economic benefit of grass carp culture is greatly increased.

Description

technical field [0001] The invention belongs to the technical field of grass carp culture, and in particular relates to a culture method for reducing the mortality of grass carp. Background technique [0002] Grass carp, also known as grass squid and grass root fish, belongs to Cyprinidae, Cyprinidae, Yaluo subfamily, and grass carp genus in taxonomy. It inhabits the middle and lower layers of rivers and lakes. It is a herbivorous fish and is mainly distributed in my country. The three major water systems of the Yangtze River, the Pearl River and the Heilongjiang River are currently the most productive freshwater fish in the world, and they are also one of the four major freshwater fishes in China. During the breeding process of grass carp, bacterial red skin disease, gill rot, enteritis and other diseases often occur concurrently, which can seriously lead to the death of grass carp and seriously affect the economic benefits of grass carp farming.
