Embodiment 1

[0024] A kind of Procambarus clarkii pond ecological cultivation method, described ecological cultivation method comprises the following steps:

[0025] (1) Pond preparation: choose a pond with sufficient water source, clear water quality, no pollution, convenient drainage and irrigation, strong water retention capacity, fertile soil, and an area of ​​3 acres, with a water depth of 1.2m. A mud stem is built in the middle of the pond for the Procambarus clarkii to dig holes, Build ramps around to prevent Procambarus clarkii from burrowing and escaping. Water inlets and outlets are respectively set at both ends of the pond. The water inlets and outlets are equipped with anti-escape nets and supporting aeration equipment;

[0026] (2) Cleaning and disinfection of the pond: remove the silt at the bottom of the pond, sprinkle quicklime for disinfection, and expose the pond to the sun for 2 days;

[0027] (3) Pond maintenance before breeding: after the pond is disinfected, base fert...

Embodiment 2

[0036] A kind of Procambarus clarkii pond ecological cultivation method, described ecological cultivation method comprises the following steps:

[0037] (1) Pond preparation: choose a pond with sufficient water source, clear water quality, no pollution, convenient drainage and irrigation, strong water retention capacity, fertile soil, and an area of ​​3 acres, with a water depth of 1.4m. A mud stem is built in the middle of the pond for the Procambarus clarkii to dig holes, Build ramps around to prevent Procambarus clarkii from burrowing and escaping. Water inlets and outlets are respectively set at both ends of the pond. The water inlets and outlets are equipped with anti-escape nets and supporting aeration equipment;

[0038] (2) Cleaning and disinfection of the pond: remove the silt at the bottom of the pond, sprinkle quicklime for disinfection, and expose the pond to the sun for 3 days;

[0039] (3) Pond maintenance before breeding: after the pond is disinfected, apply bas...

Embodiment 3

[0048] A kind of Procambarus clarkii pond ecological cultivation method, described ecological cultivation method comprises the following steps:

[0049] (1) Pond preparation: choose a pond with sufficient water source, clear water quality, no pollution, convenient drainage and irrigation, strong water retention capacity, fertile soil, and an area of ​​3 acres, with a water depth of 1.3m. Build mud stems in the middle of the pond for Procambarus clarkii to dig holes, Build ramps around to prevent Procambarus clarkii from burrowing and escaping. Water inlets and outlets are respectively set at both ends of the pond. The water inlets and outlets are equipped with anti-escape nets and supporting aeration equipment;

[0050](2) Cleaning and disinfection of the pond: remove the silt at the bottom of the pond, sprinkle quicklime for disinfection, and expose the pond to the sun for 2 days;

[0051] (3) Pond maintenance before breeding: after the pond is disinfected, base fertilizer is...

Abstract

Provided is an ecological pond breeding method of procambarus clarkia. The ecological breeding method comprises the following steps of 1, pond preparation; 2, pond cleaning and disinfection; 3, pond maintenance before breeding; 4, pond water injection and aquatic plant planting; 5, shrimp seed stocking; 6, bait feeding; 7, water quality control; and 8, timely fishing. The ecological pond breedingmethod of the procambarus clarkia can overcome the correlative defects that the daily management of existing crayfish is not good, the water quality is polluted easily to cause high death rate, poor quality, low yield of the crayfish.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for ecological cultivation of Procambarus clarkii in ponds. Background technique [0002] Procambarus clarkii is commonly known as crayfish. It is shaped like a shrimp and has a hard shell. The adult is about 5.6-11.9 cm long, dark red, the carapace part is nearly black, and there is a wedge-shaped stripe on the back of the abdomen. The juvenile body is uniform gray, sometimes with black ripples. Claw long and narrow. The middle part of the carapace is not separated by mesh-like spaces, and there are obvious grains on the carapace. Crayfish are very popular because of their delicious meat. Because of its omnivorous nature, fast growth rate and strong adaptability, it forms an absolute competitive advantage in the local ecological environment. Its food range includes aquatic plants, algae, aquatic insects, animal carcasses, etc. It also kills each other when food is scarc...
