Embodiment 1

[0067] A method for cultivating loach seedling artificial propagation, comprising the following steps:

[0068] Step 1. Preparation before hatching of loach seedlings: including building hatching ponds, building nursery ponds and selecting seed loach;

[0069] 1) The steps for building the hatching pool are as follows: the area of ​​the pool is 8 square meters, and the pool is disinfected with 5% potassium permanganate aqueous solution; the 80-mesh coarse mesh and the 120-mesh fine mesh are diluted with povidone iodine Disinfect the liquid; pour in the pool water filtered by a 120-mesh fine mesh to a water depth of 0.3m, lay a layer of 120-mesh fine mesh with the same size as the pool on the bottom of the pool, and lay a layer of 80-mesh coarse mesh at a position 0.1 away from the water surface in the pool Lay a deck of aquatic plants on the 120 mesh fine net periphery at the bottom of the pond, place several plates on the 120 mesh fine net at the bottom of the hatching pond, ...

Embodiment 2

[0080] A method for cultivating loach seedling artificial propagation, comprising the following steps:

[0081] Step 1. Preparation before hatching of loach seedlings: including building hatching ponds, building nursery ponds and selecting seed loach;

[0082] 1) The steps for building the hatching pool are as follows: the area of ​​the pool is 9㎡, and the pool is disinfected with 6% potassium permanganate aqueous solution; the 80-mesh coarse mesh and the 120-mesh fine mesh are diluted with povidone iodine Disinfect the solution; pour in the pool water filtered through a 120-mesh fine mesh to a water depth of 0.35m, lay a layer of 120-mesh fine mesh with the same size as the pool on the bottom of the pool, and lay a layer of 80-mesh coarse mesh at a position 0.15 away from the water surface in the pool Lay a deck of aquatic plants on the 120 mesh fine net periphery at the bottom of the pond, place several plates on the 120 mesh fine net at the bottom of the hatching pond, conn...

Embodiment 3

[0093] A method for cultivating loach seedling artificial propagation, comprising the following steps:

[0094] Step 1. Preparation before hatching of loach seedlings: including building hatching ponds, building nursery ponds and selecting seed loach;

[0095] 1) The steps for building the hatching pool are as follows: the area of ​​the pool is 10 square meters, and the pool is disinfected with 7% potassium permanganate aqueous solution; the 80-mesh coarse mesh and the 120-mesh fine mesh are diluted with povidone iodine Disinfect the liquid; pour in the pool water filtered by a 120-mesh fine mesh to a water depth of 0.4m, lay a layer of 120-mesh fine mesh with the same size as the pool on the bottom of the pool, and lay a layer of 80-mesh coarse mesh at a position 0.2 away from the water surface in the pool Lay a deck of aquatic plants on the 120 mesh fine net periphery at the bottom of the pond, place several plates on the 120 mesh fine net at the bottom of the hatching pond,...

Abstract

The invention discloses an artificial propagation and cultivation method for loach larvae, and belongs to the field of aquaculture. The method comprises the steps of preparation before incubation of loach larvae, egg laying and incubation management, and delivery and cultivation of loach larvae. Loach is a traditional high-quality aquatic product in China, and is known as the ginseng in water. With the improvement of the people's living standard, the market requirement amount is larger and larger, and wild products cannot meet the market requirement. In recent years, the loach cultivation scale is rapidly developed, loach larvae become the bottleneck restraining industrial development, the problem of shortage of loach larvae is still outstanding, existing loach larvae are mostly fished wildly, the quality is hard to ensure, and the cultivation risk is increased. Large-scale loach artificial propagation is performed, and the key problem is how to improve the yield and survival rate of loach larvae. The artificial propagation and cultivation method aims at overcoming the defects of existing loach larvae propagation technology, solves the problem that the yield and survival rate of existing loach larvae artificial propagation are low, and improves the scientific level of loach larvae propagation and cultivation.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an artificial breeding method for loach seedlings. Background technique [0002] Loach is a traditional high-quality aquatic product in my country, known as ginseng in water. With the improvement of people's living standards, the market demand is increasing, wild products are far from meeting the market demand, and the market prospect is broad. [0003] In recent years, the scale of loach farming has developed rapidly, and seedlings have become a bottleneck restricting the development of the industry. The problem of lack of seedlings is still prominent. At present, most of the seedlings are wild-caught, and its quality is difficult to guarantee, which increases the risk of breeding. [0004] How to improve the yield and survival rate of loach seedlings in large-scale artificial propagation of loach seedlings is the key. [0005] At present, the yield and survival rate of ...
