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 artificially raising seedlings of Procambarus clarkii in earthen ponds. By setting the earthen ponds as crayfish seedling ponds, controlling the ratio of male and female of broodstock, the feed protein ratio of broodstock, and the control of water temperature in the breeding period, the simulated The natural breeding conditions of lobsters can promote the maturation of the gonads of female shrimps, thereby shortening the arrival of the breeding period, and promoting the spawning of female shrimps; after the spawning of female shrimps, the shrimp seedlings are separated from the female shrimps immediately to avoid killing the seedlings by broodstock According to the activity, feeding and development of the shrimp fry, the bait is fed on demand, so that intestinal diseases will not occur while the shrimp fry grows; Seedling cultivation, the quality of the cultivated seedlings is good, the survival rate of breeding is high, and the yield and benefit have also been greatly improved. At the same time, ordinary foam boxes or plastic square barrels are used for incubation during the implementation process. Low and easy to promote.

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...
