Problems solved by technology

The time for stocking crabs in the river crab breeding pond is around March. If the parents of freshwater shrimp are cultivated in a special pond, the pond mouth cannot be used for river crab cultivation, and the pond resources cannot be effectively used.

Embodiment approach

[0027] In order to further disclose the technical scheme of the present invention, the following describes the implementation of the present invention in detail in conjunction with specific examples: a method for cultivating freshwater shrimp parents in a river crab culture pond, comprising the following steps:

[0028] a. Preparation before stocking

[0029] ① Reinforce pond banks and anti-escape facilities.

[0030] ② Disinfection of clear ponds: After drying the ponds in winter, remove excess silt and thoroughly expose the bottom of the ponds for about 1 month. 20 days before stocking, water 10-30cm, and 50kg-100kg per mu of quicklime water is evenly sprinkled in the whole pond.

[0031] ③Fertilizer and water: Inject water to 50cm one week before stocking, and use 100-200kg of fermented organic fertilizer per mu.

[0032] ④Planting aquatic plants: planting Elodea and Hydrilla verticillium. Elodea is planted before crab species are stocked, and Hydrilla verticillium is pl...

Abstract

The invention discloses a method for breeding freshwater shrimp parents by utilizing a river crab culture pond, which comprises the following steps of a, carrying out preparation before breeding; b, breeding seedlings; c, feeding; d, fishing the parents and separating the parents in different ponds. According to the invention, the freshwater shrimp parents are bred by utilizing superior ecological conditions and sufficient bait resources of the river crab culture pond; the patents bred by the method is higher than parents bred in a special pond in both the aspects of specification and yield; the specification and the quantity of carrying eggs of ovigerous females bred by the method are obviously higher than those of ovigerous females bred in the special pond; culture of river crabs is not influenced; freshwater shrimps mainly eat residual feeds of the river crabs and are properly additionally fed with soybean cakes and bran, so that pond port resources are saved and labor intensity is reduced.

Description

technical field [0001] The invention relates to a method for cultivating freshwater shrimp parents in a river crab culture pond, and belongs to the technical field of shrimp aquatic organism breeding in agricultural aquaculture. Background technique [0002] At present, the breeding methods of freshwater shrimp parents are all cultivated in special ponds. From February to March of each year, the parents of freshwater shrimp are introduced, and they are put into a special pond to start parental cultivation. After the cultivation until the middle and late May, after a large number of freshwater shrimp have eggs, they are transferred to the special pond to raise seedlings. The time for stocking crabs in the river crab breeding ponds is around March. If the parents of freshwater shrimps are cultivated in special ponds, the pond mouth cannot be used for river crab cultivation, and the pond resources cannot be effectively utilized. The river crab breeding pond has a superior ecol...
