Problems solved by technology

At present, there are more and more artificial breeding of rice field eels, but their systematic breeding methods are relatively limited, and most of the breeding and breeding methods are not perfect, which makes the spawning rate of rice field eels low, the growth rate of seedlings is low, and the disease of rice field eels is low. and higher mortality

Embodiment 1

[0013] A method for artificial propagation of rice field eel is characterized in that the following steps:

[0014] Construction of breeding pool: In the greenhouse, build a breeding pool with a length of 10m, a width of 5 meters, and a depth of 1 meter. The water inlet and drainage system and temperature monitoring device are installed in the pool. After the construction is completed, the breeding pool is disinfected with quicklime. Lay a layer of river mud of 15-20cm on the bottom, inject 20-30cm of clear river water, plant a layer of water hyacinth on the water surface, accounting for one-third of the entire water surface area, and put 1000g of loach in the breeding pond, which can help rice field eels growth and development;

[0015] The selection of eels: mainly artificially cultivated seedlings should be adopted, and fine varieties such as dark yellow large spotted eels should be selected. They are required to be healthy, free from disease and injury, fat in shape, brigh...

Embodiment 2

[0021] A method for artificial propagation of rice field eel is characterized in that the following steps:

[0022] Construction of breeding pool: In the greenhouse, build a breeding pool with a length of 10m, a width of 5 meters, and a depth of 1 meter. The water inlet and drainage system and temperature monitoring device are installed in the pool. After the construction is completed, the breeding pool is disinfected with quicklime. Lay a layer of 15-20cm river mud at the bottom, inject 20-30cm of clear river water, plant a layer of water hyacinth on the water surface, accounting for one-third of the entire water surface area, and put 1500g of loach in the breeding pond, which can help The growth and development of eels;

[0023] The selection of eels: mainly artificially cultivated seedlings should be adopted, and fine varieties such as dark yellow large spotted eels should be selected. They are required to be healthy, free from disease and injury, fat in shape, bright in co...

Abstract

Disclosed is an artificial rice field eel culturing method. The artificial rice field eel culturing method comprises the following steps of breeding pool construction, selection of parent eels, pre-breeding culture and management of the parent eels, parturition hastening, artificial fertilization and hatching. The artificial rice field eel culturing method ensures excellent quality of the parent eels through scientific management and a rational culturing mode, improves the spawning rate through artificial parturition hastening and fertilization, and improves the hatching rate of fertilized spawns through lentic hatching.

Description

technical field [0001] The invention relates to the field of breeding, in particular to an artificial breeding method for rice field eels. Background technique [0002] Swamp eel is commonly known as eel, field eel or field eel, also known as long fish, blood fish, luo fish, scaleless son, etc. It is edible and has economic value. Swamp eels like to inhabit ponds, ditches and rice fields, and they are omnivorous fish that mainly eat animal food. At present, there are more and more artificial breeding of rice field eels, but their systematic breeding methods are relatively limited, and most of the breeding methods are not perfect, which makes the spawning rate of rice field eels low, the growth rate of seedlings is low, and the disease of rice field eels is low. and higher mortality rates. Contents of the invention [0003] In order to solve the above problems, the present invention adopts the following technical solutions: [0004] A method for artificial propagation o...
