Embodiment 1

[0038] A kind of culturing method for nesting crayfish in lotus root pond, comprises the following steps:

[0039] S1. Pond preparation: choose a pond with sufficient water source, convenient drainage and irrigation, sunny ventilation, good light, flat bottom and thick soil layer. The pond is provided with a water inlet and a water outlet, and the water inlet and the water outlet are provided with a filter. 60 centimeters of high anti-escape nets are set around the pond; shrimp ditch is dug around and in the center in the pond to form a "field" shaped shrimp ditch, and the shrimp ditch is 1m wide and 0.5m deep.

[0040] S2. Pond disinfection: spread the above materials evenly on the bottom of the pond according to the ratio of 60kg of quicklime, 10kg of tea bran and 1kg of Bordeaux mixture per mu. After 7 days in the selenium pond, add water to the water depth of 10cm and disinfect for 7 days; Drain it clean, and wash it repeatedly until the pH of the pond is about 7.

Abstract

The invention provides a breeding method for companion breeding of crayfish in a lotus-root pond, and belongs to the technical field of aquaculture. The breeding method includes the following steps ofpond preparation, pond disinfection, lotus root planting, crayfish seedling casting and aquaculture management. According to the breeding method, companion breeding of lotus roots and the crayfish isadopted, so that resources are utilized reasonably, aquatic plants and biological bait in the lotus-root pond is used as natural feed of the crayfish, not only can an effect of ecological weeding forthe lotus-root pond be achieved, but also the utilization rate of the lotus-root pond can be improved; secondly, excrement of the crayfish can be added as organic fertilizer for the lotus root pond,so that a virtuous cycle is achieved. Due to blooming of the aquatic plants in the lotus-root pond and abundance of multiple benthic animals and organic debris, the crayfish are provided with rich food sources, so that the breeding cost is low, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for cultivating crayfish nested in lotus root ponds. Background technique [0002] Crayfish are also called Procambarus clarkii, red crayfish and freshwater 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.
