Embodiment 1

[0015] With 10 acres of breeding land and 500 cages as the implementation unit; time: 2017, the breeding period is 110 days;

[0016] Set up net cages in the pond, choose polyvinyl chloride net cages, and the size of a single net cage is 1-2m 2 , Mesh 60 mesh, after placing the net cage, plant the aquatic plants in the net cage after insecticide and disinfection, and the coverage rate of aquatic plants reaches 80-90% of the water area in the net cage;

[0017] Throw in seedlings, and the eel breeding period is divided into three cycles: training period, feeding period and feeding period;

[0018] a. The training period is 3 days, feeding once a day from 2:00 to 5:00 in the afternoon, feeding a total of 7.5kg of duck eggs, 30kg of earthworms, and 0.5kg of Victoria;

[0019] b. The feeding period is 7 days, feeding once a day from 4:50 to 6:00 in the afternoon, feeding a total of 15kg of duck eggs, 15kg of earthworms, and 0.3kg of Victoria;

[0020] c. The feeding period is 90...

Embodiment 2

[0024] With 10 mu of breeding land and 500 net cages as the implementation unit; time: 2016, the breeding period is 110 days;

[0025] In the present embodiment, other steps are all the same, and the difference is that Tenebrio molitor is replaced with duck eggs to increase the usage of earthworms;

[0026] Present embodiment Tenebrio molitor consumption 3500kg, earthworm 2700kg;

[0027] The breeding effect of embodiment 1 and embodiment 2 is compared, see the following table:

[0028]

[0029] As can be seen from the table, under the similar situation of breeding, adopting the method of the present invention can effectively reduce the cost of Tenebrio molitor and earthworm.

Abstract

The invention discloses a method for breeding ricefield eels. The period of breeding the ricefield eels is divided into three periods including a feed training period, a feed attracting period and a feeding breeding period, and duck eggs are used as main auxiliary feed in each period. By means of the method, yellow mealworms are replaced by the duck eggs for feeding the ricefield eels, earthwormsare reduced, invasion of harmful bacteria can be effectively reduced, the ricefield eels taste smooth during feed training and are high in nutritional value of protein, unlikely to get sick and high in immunization rate, the quantity of drugs at usual time is reduced, and the survival rate is high. At the same time, due to the use of the duck eggs, eel feed with a slightly lower content of proteincan be used, the cost is reduced, and economic benefits are high.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for raising rice field eels. 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. In the traditional breeding method, earthworms and Tenebrio molitor are often used as auxiliary materials on the basis of feed, which is not only costly, but also easily increases the invasion of harmful bacteria. Contents of the invention [0003] The object of the present invention is to provide a method for raising rice field eels, using duck eggs to eliminate Tenebrio molitor and reduce earthworms, with high nutritional value, less disease, high survival rate and low cost. [0004] To achieve the above object, the p...
