Disease-preventive method for cultivating four major Chinese carps

Abstract

The invention discloses a disease-preventing breeding method for four major domestic carps. 1) Fish ponds: set up successively connected grass carp fish ponds, herring fish ponds, bighead carp fish ponds, silver carp fish ponds, crucian carp fish ponds and shrimp fish ponds. pond, each fish pond is provided with a certain slope from the water inlet to the water outlet, the water inlet and the water outlet are all provided with protective devices, and the water outlets of the crucian carp fish pond and the shrimp fish pond are provided with water 2) Cultivate fish fry; 3) Fish pond management. According to the present invention, the fish ponds are set as successively connected grass carp fish ponds, herring fish ponds, bighead carp fish ponds, silver carp fish ponds, crucian carp fish ponds and shrimp-raising fish ponds, and each fish pond is provided with A certain slope makes the fish have a better activity place and circulating water flow in the fish pond, promotes the swimming of the fish, increases the activity of the fish, enhances the physique of the fish, increases the feeding ability of the fish, reduces the disease of the fish, and promotes the grow fast.

Description

technical field [0001] The invention belongs to the technical field of cultivation of fish, mussels, clams, lobsters, sponges, pearls, etc., and in particular relates to a cultivation method for disease prevention of four major domestic fishes. Background technique [0002] In the breeding process of aquatic products such as fish, it is usually stocked by relying on natural water resources by the river, lake or coast. Discharging the rivers, lakes or coasts will cause river pollution and easily lead to large-scale illness and death of the four major domestic fishes, causing heavy losses to farmers. In addition, in storms or sudden changes in cold weather, fish will die or run away on a large scale , there is another method of breeding and stocking fish by digging artificial fish ponds. However, due to the large number of genetically modified crops, the extensive use of chemical fertilizers and pesticides, and the large amount of vehicle exhaust emissions, there are still a l...

[0002] In the breeding process of aquatic products such as fish, it is usually stocked by relying on natural water resources by the river, lake or coast. Discharging the rivers, lakes or coasts will cause river pollution and easily lead to large-scale illness and death of the four major domestic fishes, causing heavy losses to farmers. In addition, in storms or sudden changes in cold weather, fish will die or run away on a large scale , there is another method of breeding and stocking fish by digging artificial fish ponds. However, due to the large number of genetically modified crops, the extensive use of chemical fertilizers and pesticides, and the large amount of vehicle exhaust emissions, there are still a lot of dust particles in the air. And acid mist particles, if left in fish ponds in rainy days, it is also easy to cause large-scale illness and death of the four major family fish, causing heavy losses to farmers
