Embodiment 1

[0018] Embodiment 1: The method for artificially imitating ecological seedling breeding of the field eel net cage comprises the following steps:

[0019] A. Cage production: use polyvinyl chloride cages, and the size of a single cage is 1m 2 . The mesh density is 60 mesh. From March 1st to April 20th, place the cages in a water body with a flow velocity of 0.05-1 m / s;

[0020] B. Planting aquatic plants: After placing the cages, kill insects and disinfect aquatic plants (the ratio of water peanuts to water hyacinths is 1:2.33) and plant them in the cages. The coverage rate of aquatic plants reaches 80% of the water area in the cages. ;

[0021] C. Parental selection: select the parental field eel with no disease, no trauma, strong vitality, yellow color and robustness, the age of the fish is more than two years, and the individual weight is 70-80g;

[0022] D. Timely planting: The planting time is selected from May 1st to May 20th, when the weather is fine, the planting spec...

Embodiment 2

[0024] Embodiment 2: the method for artificially imitating ecological seed breeding of the field eel cage, comprising the following steps:

[0025] A. Cage production: use polyvinyl chloride cages, and the size of a single cage is 1.5m 2 . The mesh density is 60 mesh. From March 1st to April 20th, place the cages in a water body with a flow velocity of 0.05-1 m / s;

[0026] B. Planting aquatic plants: After placing the cages, kill insects and disinfect aquatic plants (the ratio of water peanuts to water hyacinths is 1:3.2) and plant them in the cages. The coverage rate of aquatic plants reaches 85% of the water area in the cages. ;

[0027] C. Parental selection: select the parental field eel with no disease, no trauma, strong vitality, yellow color and robustness, the age of the fish is more than two years, and the individual weight is 70-80g;

[0028] D. Timely planting: The planting time is selected from May 1st to May 20th, when the weather is fine, the planting specifica...

Embodiment 3

[0030] Embodiment 3: the method for artificially imitating ecological seed breeding of the field eel net cage comprises the following steps:

[0031] A. Cage production: use polyvinyl chloride cages, and the size of a single cage is 2m 2 . The mesh density is 60 mesh. From March 1st to April 20th, place the cages in a water body with a flow velocity of 0.05-1 m / s;

[0032] B. Planting aquatic plants: After placing the cages, kill insects and disinfect aquatic plants (the ratio of water peanuts and water hyacinths is 1:4) and plant them in the cages. The coverage rate of aquatic plants reaches 90% of the water area in the cages. ;

[0033] C. Parental selection: select the parental field eel with no disease, no trauma, strong vitality, yellow color and robustness, the age of the fish is more than two years, and the individual weight is 70-80g;

[0034] D. Timely planting: The planting time is selected from May 1st to May 20th, when the weather is fine, the planting specificat...

Abstract

The invention discloses an artificial bionic method for breeding rice field eel fries in net cages. The method comprises steps of net cage manufacturing, float grass planting, parent selection, proper fry throwing, fry cultivation and the like. The method has the characteristics of low parent mortality, high spawning rate, high fry survival rate and low fry cost. The net cages can be used for simulating the natural growing environment of rice field eels, so that the probability of invasion of rice field eels by natural enemies in a breeding process is lowered; a high-nutrition mixed feed is adopted, so that the growing speed and spawning rate can be increased; the feed is applied at a temperature which is most suitable for the growth of rice field eels, so that the spawning rate of rice field eels is further increased. According to the artificial bionic method for breeding rice field eel fries in net cages, the defects of the prior art are overcome, the production cost of fries is lowered, the profit of culturists is increased, the market demand is met, and a very good market prospect is achieved.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a method for artificially imitating ecological seedling breeding in rice field eel cages. Background technique [0002] Rice field eel, commonly known as squid, is a temperate aquatic fish. It is rich in nutrients, tender in meat, rich in protein, DHA, lecithin, vitamin A, and various trace elements. It has good medicinal and edible value, and can be made into a variety of delicacies, which is deeply loved by people. [0003] Field eels have the characteristic of sex reversal, changing from female to male after laying eggs once. Naturally grown rice field eels have a small amount of eggs and low egg production. In addition to overfishing, the number of wild rice field eels is very small, which cannot meet the needs of large-scale artificial breeding, and the market gap is very large. Contents of the invention [0004] The purpose of the present invention is to provide a method for art...
