Embodiment 1

[0013] A kind of propagation method 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. It is required to be healthy, disease-free, fat-bodied, bright in color, and dark yellow ...

Embodiment 2

[0021] A kind of propagation method 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. It is required to be healthy, disease-free, fat-bodied, bright in color, and dark yellow in body...

Abstract

Provided is a reproduction method of finless eels. The method includes the following steps of construction of a reproduction pool, selection of parent eels, pre-childbearing breeding and management of the parent eels, spawning induction of the parent eels, artificial fertilization and hatching. According to the reproduction method of the finless eels, scientific management and a reasonable breeding method are adopted, so the good quality of the parent eels is guaranteed from the step of breeding of the parent eels; by the adoption of artificial spawning induction and the artificial fertilization, the spawning rate is improved; meanwhile, lentic hatching is adopted, so the hatching rate of fertilized ova is improved.

Description

technical field [0001] The invention relates to the field of reproduction, in particular to a method for breeding 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. Distributed in the freshwater basins of China, Taiwan, Japan, India and Southeast Asia in Asia, the breeding season is from May to August. Field eels often have problems such as low spawning rate, low fertilization rate, and low hatching rate during the breeding process. Contents of the invention [0003] In order to solve the above problems, the present invention adopts the following technical solutions: [0004] A kind of propagation method of rice field eel is characterized in that the following steps: [0005] 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....
