Embodiment Construction

[0017] A kind of method for the earthen pond artificial seedling raising of Procambarus clarkii comprises the following concrete steps:

[0018] (1) Establish an earthen pond with an area of ​​about 15 square meters as a nursery pond, control the water depth of the earthen pond to be more than 1.3 meters, set up an inlet and outlet, set up 4 bait tables and equip 2 aerators, and set up concealed objects at the bottom of the pond including aquatic plants and PVC Tubes, nets, etc., account for about 40% of the pond area. The broodstock shrimps are exposed to the sun 20 days before entering the pond, and the dry pond is disinfected with quicklime. Filter and inject water about 1 meter deep;

[0019] (2) Select individuals with body length of more than 15 cm, weight of more than 80 g / tail, healthy and disease-free, complete and smooth appendages, bright color, and strong activity as broodstock, and control the ratio of male to female at 3:1, October After the middle ten days, the...

Abstract

The invention discloses a method for artificial breeding of procambarus clarkii in a soil pond, which is characterized in that a soil pond is set to serve as a nursery pond for procambarus clarkii, natural breeding conditions of procambarus clarkii are simulated through controlling the male to female ratio of parent procambarus clarkii, the feed protein ratio of parent procambarus clarkii and thewater temperature during the breeding season, and gonad maturation of female procambarus clarkii is promoted so as to shorten the arrival of the breeding period and promote the female procambarus clarkii to lay more eggs; the young procambarus clarkii and the female procambarus clarkii are separately fed after egg laying of the female procambarus clarkii so as to avoid the parent procambarus clarkii from killing the young procambarus clarkii, bait feeding is carried out according to the activity, feeding and development conditions of the young procambarus clarkii, and the procambarus clarkii are fed on demand, thereby achieving the growth of procambarus clarkii without the occurrence of intestinal diseases. The technical method of the invention carries out young procambarus clarkii breeding by adopting the soil pond, the bred young procambarus clarkii are good in quality and high in breeding survival rate. In addition, the yield and the benefit are also greatly improved. Meanwhile, ordinary foam boxes or plastic buckets are adopted for hatching during the implementation process, and the young procambarus clarkii are neat in specification. In addition, the method is low in breedingcost and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of lobster culture, in particular to a method for artificial cultivation of Procambarus clarkii in earthen ponds. Background technique [0002] Procambarus clarkii, also known as red marsh crayfish, crayfish or crayfish, has the characteristics of fast growth, miscellaneous food habits, strong adaptability, resistance to low oxygen / less diseases, easy breeding and transportation, etc., and the meat is tender and delicious. Delicious, deeply loved by consumers. The traditional breeding method of crayfish has low survival rate of shrimp seedlings, low yield and poor benefit, which greatly affects the breeding enthusiasm of farmers. Contents of the invention [0003] The purpose of the present invention is to provide a method for artificial seedling cultivation of Procambarus clarkii in earthen ponds in order to make up for the defects of the prior art. [0004] The present invention is achieved through the...
